Woah hello I’ve seen your vids before

Best panel scantronic ever made imo and arguably the best domestic alarm system you could get, not many out there now but I guarantee the ones still in operation will far outlast most modern panels installed today!

nothing beats the old scantronic 9600. my 9600 is 32 years and still works perfect to this day, good solid panel as long as you remember to change the battery. they are very rare now. its just a shame a lot of people replace them for cheap trash. nice to see you have looked after yours. as for your question probably all they had in the van at the time or simply couldn't be arsed to get the correct size,

Haha, some fucker's thumbed this video down already. Some people are never happy! What's the matter, afraid you're gonna be stuck with that box of 1.2Ah batteries you were planning to install? :D :D :D

Bro, bro, smiling, i not understand them either, why they thumb you down. You call them fuckers ? I smile, fuckers !

Price and money making. many people who have security systems installed, do not know much about them, or if they even have a battery in them, a tiny battery is more likely to get deep cycled if ever used, and for those who do not know much about them, when the system starts giving warnings. they simply call the company, and they whack in another cheap tiny battery and then charge the customer like $150-200. so while many people will replace it on their own, there are those who will rather call the company to come out and do it, and due to the high profit margin, i they can make those calls happen more often, then it is a nice addition to the bottom line for the company.

any alarm engineer would have fit a 7 ah battery...if they had one in there van,otherwise they probably just used a 2.6 ah battery to save a return visit and not look stupid!! the 7 ah battery is recommended for this panel as it can keep several devices running longer.having a 7 ah battery means your alarm will last longer in a power cut over a 2.6 ah.i have the same panel it ran for a day whilst the electric was off..Batteries should be changed every 5 years,regardless of what they look like.Some last 8/9 years,others will last a mean 3 years,bit of a lottery,really.not worth risking,though,im an alarm engineer and ive seen faulty batteries damage the pcbs and cause all sorts of mayhem for the owner at 3 am.9600 best panel ever made imo

I am a licensed installer from Perth Western Australia. When an alarm is monitored (in WA monitoring can include the alarm sending you an SMS with the zone(s) that has gone off) the battery must be sized to keep the system running for a minimum of 16 hours. If the system does not have monitoring it must keep the system running a minimum of 24 hours. ALL the panels I install come from the factory with 7 Ah batteries as standard. If I have a system that has a greater need for more than ~300mA draw from the battery (ie the panel, all the keypads, detectors etc) I split the power across the panel and a second enclosure with a battery backed supply and another 7Ah battery (Why 7Ah batteries ? Enclosures and PSU boards and a 7 Ah battery are usually cheaper than 17Ah batteries (which need a higher charging current as we can not take longer than 48 hours to fully charge the battery (most smaller panels only charge at ~350mA)..... If I am using a commercial panel (and most of my work these days is industrial sites) then they can charge 17Ah batteries and have a link on the board to put the charger into a high current mode for the larger battery.

I just left the alarm panel field as a technician, prototype board creator, and software developer a year ago. The batteries are rated at a particular mohs level and a specific amp/hr requirement. We had specific requirements for how long the panel should last unpowered, but also gave the customers the option to upgrade them. The amp/hr rating you can see, however the mohs value you cannot. It is all about efficiency for the application the panel is to be used in along with the customer's requirements of operation.

Battery size selection should be based on how long you require a system to run in the event of a mains fail. The battery should be selected based on the total current draw of the system and the minimum time you require the system to function without mains power. The battery is then generally replaced when the capacity falls below 60% of its rated capacity

I had made a similar observation. The alarm system in my rental property had been installed with a no-name 1.2 Ah battery. After about 3 years, it was dead and could not even sustain the alarm panel for 2 seconds. I replaced it with a 7.2 Ah standby rated Yuasa battery. 2years later, I tested it and found that it could barely sustain the panel for 5 minutes. I guess the issue is that even a 1.2 Ah battery could sustain the panel for 6-12 hours if it was in good condition, and that's good enough for 99% of power cuts. However, landfill-grade charging circuitry in the panel will destroy any battery within a couple of years. Possibly even more so, if the panel is installed in an area exposed to heat (e.g. airing cupboards, or plant cupboards shared with a boiler, etc.) The smaller batteries, may be slightly cheaper, but they will be lighter and smaller, so easier to transport and ship - I guess, if you're installing loads, it all adds up.

Purely economy. Not that the SLA batteries are ideal for the constant trickle charge they get. They fail quite quickly.

@jakubbrach1045

I guess most of the batteries chemistries are prone for trickle charging (specially if performed poorly, with cheap circuit without temperature compensation). However, Lead-Acid chemistry seems to be most robust, for sure more robust than lithium based ones. When Led-Acid battery is tricke-charged it's just loosing water, due to electrolysis. Old fashion Lead-Acid batteries offered possibility to refill lost water and it made them immortal in this application.

It's basically because a 2.8Ah battery will give a minimum of 12 hours of back up (as per the British standard) and it will last about 2-3 years in the panel before it needs changing. Whereas a 7Ah battery will work perfectly, but will not necessarily cause any issues until about 5-6 years. Therefore, it's purely a profit making scheme as the wholesale cost of the batteries is only about £1-3 difference. Ex alarm installer

As long as the voltage and battery chemistry are compatible any battery could technically be fitted. From a design and product engineering standpoint the manufacturers will choose the most cost effective option that meets performance specifications within a given cost constraint, and variations throughout a manufacturing cycle occur due to supply forces such as availability, cost variations and vendor relationships. Suitability of a variety of different commodity items gives the manufacturer agility throughout production, support and service operations.

I'm a licensed installer. It's a combination of things. Many panels come with the 4.5ah from the factory because it's cheap. Then the technician who replaces it may not have the good sense or decency to recommend a bigger battery. If you can fit a 7 or 12ah battery, making sure the terminals do not short anything out, go with that. Be sure to replace your battery every five years. Also, I would recommend you test your system on AC and battery, AC only, and battery only, on a regular basis. You should probably muffle the siren when testing so your neighbors don't get accustomed to hearing false alarms causing them not to pay attention during a real alarm. Oh, and don't forget to inform your monitoring service you will be testing.

+AintBigAintClever Sounds good. Also, when the installer replaces the battery every 5 years, keep your old battery. You may need it for a temporary fix should your new battery fail. Lots of times, the service company just sends it to the recycler. It's your battery, you paid for it, find a use for it. Turn it into a backup charger for your phone or something. One more thing, I would make sure your siren goes off if the phone line is disconnected, this is optional in most systems I've seen.

Interesting, I'd have thought the main battery will make the alarm stay quiet for longer (not sound for longer) before it goes flat, at which point the battery in the bell box will start sounding the alarm. A bigger battery IN THE BELL BOX would make the alarm sound for longer (up to the 20 minute time limit) and keep the strobe going for longer (until the battery goes flat). That a larger capacity battery wouldn't make the alarm louder is pretty obvious.

I'd say for price reasons.

Im not an installer, but my hobby is electronics. Sounds like they get deals on lower capacity batterys, the question i would ask is: how long would the alarm run for on a certain capacity battery when the mains has failed?

what's on back of van half the time, but if you measure a Yuasa 2.8ah battery it may have up to 4ah in it

I think that the 7Ah battery is generally cheaper then the odd smaller sized batteries, as the 7Ah are very common, you can even get 9Ah capacity in the 7Ah casing. (thinner and more plates) Most alarm batteries last about 3 to 5 years as they never get a proper discharge test, and generally fail on overcharging. The series glowlamp will light up when the battery is on the way out. No idea why the smaller sized batteries are fitted. The Yuasa batteries are very good quality

Bloody bean counters always have to ruin things. Yep it's totally cost. If you're really keen, you could replace it with an 18Ah, and mount it externally. Would take longer to charge after a blackout, but it's more backup time. If you go any bigger than that, you may want to use an external float charger to help it out.

Where i worked we had intruder and fire alarm panels, many had Yuasa batteries, but they were replaced over the years with the CS3 batteries like the one you have. I can only guess it's what the guy had in the vehicle at the time, do a quick fix and get onto the next job. I actually have a CS3 12/7,5 that i use occasionally, still holds the charge after over 5 years.

The CSB batteries seem to be the unit of choice in APC UPS systems. For our various UPSes at work it's usually my job to change the batteries and it's usually CSB out, CSB in. Other ones I've come across have been BB Battery and Panasonic (Compaq T1000h UPSes had four 6 volt Panasonics) although I think the Vision battery in this video was one of two survivors from a rackmounted APC. I've got about 50 CSB GP1272s in the garage, they're all just over five years old but still hold between 3.5Ah and 4Ah.

AintBigAintClever The dead RBC-7 pack that came with my used APC Smart-UPS 750XL had a couple of 17AH batteries made by "sacred sun". I've never heard of them before but it seemed to be a genuine APC pack. They got replaced with a couple of ritar batteries and I've plugged a couple of Lucas LSLC12-22 into the back too. As to your question I guess the smaller battery would die quicker because of deep cycling so the installer gets more business.

AWesome video!

Learned this a long time ago. Mine had a 1.2ah battery, called alarm company they said its only $59 plus install fee to replace. Opened the panel, measured what I could fit, put in a 10ah from Ebay with 5 year warranty for like $20 shipped. Have not looked back.

When I did alarms (15+ years ago) the battery was supposed to be sized depending on the type of panel and all the devices connected to it - the idea being that the battery would be able to power the whole system for at least 24 hours without any mains power. As for smaller batteries - cost cutting, cheapness, people who shove in any size battery without actually knowing what size they should use, those that buy cheap alarm kits which include a tiny little battery. Old batteries cause false alarms - the battery should be replaced every few years, same with the outside siren module which also contains a battery. Fairly likely that people who don't have an annual maintenance contract don't have the battery replaced ever.

I have a question, can you fit a battery to those gsm alarm system that come with really small battery that won't last more than 2h. I just wonder if the gsm alarm system does not have a charge controller (that will handle changing external 12v batteries like shown in this video) any comment will be much appreciated. Many thanks

I would think one of 2 things: Its either the 2 or 3 pound price difference or it is to fit into minimum standards then charge a shit ton of money to make a profit on it. Personally I would after an installation actually look into the alarm and check what kind of battery is in it and just replace it with a larger one like 7 aH if it can handle it and if there is a smaller one in there. The other thing I would do if possible is request that it be installed with a 7 aH or 9 aH battery. I am NOT a security system installer or technician, just an electronics hobbyist at the moment, so what I'm stating here is purely opinion.

It's purely the installer trying to save cash back when gel-cell lead batteries used to have a lot of cost difference between capacities, and as you said, they probably hadn't been touched in over a decade.

Simple cost cutting. The battery will need to provide power only to drive the siren for 5 minutes when it is activated. The smaller one will always be cheaper wholesale and will do the job so long as the power supply is reliable. Here you might find panels with 2 separate batteries and 2 chargers, simply because power cuts are commonplace and tend to last for a few hours. If the expected power cut is 15 minutes in a year then the cheap small battery will last exactly as long as the big one, 5-7 years. Likely most of the batteries were over 5 years old, and have never been replaced since the systems were installed.

Hardly any of that is true for a professional system. The only point I would agree with is that those smaller batteries were probably installed many years ago.

Not many 9600's out there now...... the reason why is cost and space and what is in the van, and whats in the panel. our regs state that the back up battery has to last for 8-12 hrs, so an appropriate capacity battery is fitted to comply with the regs, however we don't carry an unlimited amount and selection of battery's in our vans so if your running low on battery's then a couple of battery changes come in at the end of the day you end up fitting whats in the van, so long as it comply's with the regs of course. I usually have 3 of each type in my van, which is ok most of the time but sometimes emergency comes in and you use what you have.

The latest panels take 18 ah batteries now to cope with eu regs on grade 3 jobs. Some old panels are designed to only take the 3.2 ah battery others the 7ah and some only a 2.1 ah battery it depends on the size of the system. The battery life depends on where the panel is, if its in a boiler cupboard for instance it will cook the cells and only maintain optimum charge for a few years. 7 ah yuasa batteries tend to last about 4 years in my experience before the ACT battery tester fails them. On very large systems there are psu's next to expander panels holding further backup batteries.

It's down to what the engineer has on his van.

im not an alarm installer but i am an EE and my guess is that the smaller battery that they do install has a longer life, lower drop or a lower ESR

I installed a 1.3ah into my Menvier TS900, but then it started to fizz and crack, so it is about the electronics. I put in a 7ah and it works fine!

9600, old Skool-- open end station --

I've just re-read the original video description and realised that I got called out the Sterling 10 mentioned above a few weeks ago, because of a faulty panic button (the house has changed ownership since the battery was replaced). Having seen the documentation showing who originally installed the panel, I'm not surprised at the choice of battery. They've pulled their socks up since then but back when the panel was installed they had a reputation of being fucking cowboys and are the sole reason we now have a list of approved network jacks at work (to prevent them installing the cheapest shit they could get their hands on).

One thing I have thought of, which no-one else has yet mentioned is....... Speed of recharge. A small one may recharge to full power quicker than a large one, meaning that if there was a power cut and then the power came back on, the battery would recharge to its top power sooner than what a big one would. Another thing as well: Lets suppose that, after recharging a small battery, the recharging electronics were quite warm..... Installing a larger battery might mean that the extended recharging time may cause the electronics to overheat and =POP=. And then there's things like weight and cost. If those batteries you have there are past their useful lives, I have heard that they can be recharged on an arc welder. They let you know when they're fully recharged, because they whistle at you! :D ROFL!! Aaaah, go on.....make a Whistley-Squeeler. It's always fun! :D Thanx for showing, -BoomBoxDeluxe. _23rd February 2014, 18.31_

But a larger one would've lost less charge (as a percentage) than the smaller one, so recharge should take the same time (unless the power was off long enough to flatten the smaller one, where the big one would keep going).

Or ofcource the alarm company could have ordered one in massive bulk or had a contract allowing the producer of the battery to raise their prices who want to have it replaced

The alarm on this house (dead as a dodo, have no way of knowing how to work it!!) had a 1.2Ah battery in it which was completely goosed, though I'm not sure if it would even take a bigger battery, haven't looked inside the panel since last year... :P

The battery is smaller because it does basically the same job But it also saves money on your electric bill, because a battery is constantly losing power, so it is in a constant state of recharging, So logically the battery takes more to charge a bigger battery... That what I think... Others may think differently though :D

Self-discharge rate of a sealed lead-acid battery is very, very small, about 5% per month, so there won't be much difference in the amount of power being consumed by keeping that battery topped up.

Purely economy. When they buy them in pallets of 1000 at a time the price is more sensible with small batteries costing less.

The standby times are specified in the BS regulation, and vary depending on the the type of systems installed ie police response systems

they do it to make you feel bad

I dont really understand the difference, both batteries will do the same work. I have the small 1.2Ah battery installed, when i was on holliday it screamed for 4 days nonstop due to power failiure (it was powerded by the battery) until someone had to come and turn it off. Cost saving might be the factor, but i dont think its crippleing your security.

It shouldn't have gone off due to the power failure, the battery's meant to prevent that. The siren has its own battery and will go off if the power to it is removed (in other words mains has gone and the backup battery has gone flat). A bigger battery would've kept the alarm quiet for longer.

@TheNeurall

Yeah thats right, when power goes off, it should be queiet until its restored. What happent here is, that power went off, than in went on for a while and it started screaming, but the power was on for about an hour, than it went off for about 5 days until electican came to fix it. If it managed to scream almost 4 days on battery, im sure the battery could keep it quiet for much longer. But anyway im thinking of changing the alarm, the problem is stupid design, not the battery as much, i think.

Economicly reason thats all what is the best deal for that moment. The capacity 7 9 or higher is depending where you use it and how often and how long you have power blackouts. The higher the nr the longer it can overbridge the blackout. The when the alarms goes off it needs to work for 20 min as seen in other comments that is i thing police reaction time. The chargers in those systems are most of the time just power supplys that are keeping the battery on its stabelize voltage. From discharge till fully charged take most of the time a few hours. The the size of the battery needs to fit in the alarm unit. But the engineer makes it so the cheapest battery goes in the unit. So actualy there is no difference in different size of the battery the voltage and ah are the important numbers. The tell you the capacity of the battery.

TECHNICAL in my opinion they might didnt make battery rechargable so it can handdle system longer and i saw somewhere in simmilar box bouble 7ah batteries so yea

Personally in my opinion. Its a money thing. First of all they won't expect you to run it long enough to drain even though its possible and 2nd, seeing as lower capacity batteries are cheaper, I would think they could score a higher profit margin using lower cost batteries (and even more to pay extra to upgrade them.) thats just my opinion though.

I my self fit the biggest I can fit, ( I am from this trade) if the engineer does his job correctly then this should all be worked out as to what size should be fitted by what is on your system and what mA it's drawing, a lot of engineers are lazy and normally have messy installations so can't fit the biggest they can as there are cables all over the show! Just to put you in the picture on some industrial installations and depending on the grading there will be a 17ah fitted or two 7ah together. Andy

I'd be careful about that, you don't want to overload the panel's battery charger. A CSB HRL1234W is an 8.5Ah battery that would fit a 7Ah hole, for example, but the charging graphs on the datasheet seem to suggest that it would pull a lot more current than a "normal" 7Ah battery, so I wouldn't fit one to a panel unless someone more knowledgeable about such matters told me otherwise. Constant voltage charging appears to be the order of the day when it comes to these, but I don't know if the panels feature current limiting or will just dole out whatever the battery asks for (or die trying).

That's one way of doing it. Another would be to replace the panel with a newer one (look on eBay) and use the alarm's various outputs to interface with the Pi. That way you keep the built-in security features of the alarm (tamper detection, EOL resistor support, etc.) and add web/email capability. Choose an alarm with inputs capable of acting as a key switch and you've got the whole lot under Pi control. The Menvier TS790, TS900 and TS2500 for example will support this (the TS2500 incidentally can take a 17Ah battery, along with 1040 zones and 512 keypads). Plenty of scope there too to decipher and interrogate the keypad data bus :)

increased call out charges

sorry 15 minute time limit at nacoss

Weight, price and long term power not needed

The battery is only there to power the alarm during power failures. All a bigger battery will do is make the alarm sound for longer before it goes flat. It won't make the alarm louder, or more reliable. However, your alarm should have a time limit of no more than 20 mins before it silences itself (this is to comply with noise abatement issues). The standard battery will last for MUCH longer than 20 mins in a power failure before it flattens, so why waste money fitting a bigger one? No reason not to fit a bigger one, but it's your money, so go ahead and waste it if you wish.

Probably laziness and convenience of what they had in the van.

Less Weight. Cheaper shipping

Economy and cheating, here many companies install smaller battery in place of a bigger one to save those few dollars. We had many places where things like that were done, for personal use I would say normal size will do, besides this batteries die after time, so no point for bigger, it only needed to stay alive if mains gets cut off and to send a message to guards or you or just to start the alarm in that moment, well depending on setup.

The bigger the ah (amp hour), the longer the alarm will be up and running in a power failure.

Makes it much easier to figure out what's going on, especially when getting your head round the "wards" and translating that into groups for part-setting and stuff (hint: if a zone is in two wards, it's only armed if both wards are armed, also if your entry exit is in ward A and you have an access route only in ward B, you WILL set off the alarm on your way to the keypad).

I would say for the sake of making money these companies want to drain every last dollar out of you.

This is why alarm engineers that are self employed can spend up to 50 minutes using the toilet...... So no, there is no reason not to use a 7AH battery. This grade of panel is for large domestic / small commercial installs. NACOS and other industry bodies do actually specify the time a system should run on standby. The 9600 was the brother of the 9800 panel that just had an LED display. Its a rock solid and very reliable panel aside from the keypad keys wearing out and having a dodgey back tamper they are great alarm panels. I installed one in my parents home for them that ran for nearly 20 years before they moved. It looks you yok have the zone expander and a comms board plugged onto that panel. Keep it and use it. Sadly scantronic have been purhased by Cooper Menvier and my personal opinion is that the quality has dropped since then. Scantronic made some great panels like the 9100 (showing my age now) 9500, 9600, 9800 and the 448. Shame they didn't carry on as they were. I still have a 9100 boxed and its works as well today as it did 20 years ago. Nice to see one again. Thank you and all the best. :)

Economicly reason thats all what is the best deal for that moment. The capacity 7 9 or higher is depending where you use it and how often and how long you have power blackouts. The higher the nr the longer it can overbridge the blackout. The when the alarms goes off it needs to work for 20 min as seen in other comments that is i thing police reaction time. The chargers in those systems are most of the time just power supplys that are keeping the battery on its stabelize voltage. From discharge till fully charged take most of the time a few hours. The the size of the battery needs to fit in the alarm unit. But the engineer makes it so the cheapest battery goes in the unit. So actualy there is no difference in different size of the battery the voltage and ah are the important numbers. The tell you the capacity of the battery.
