Another great video - Thanks. A great shame that the main case isn't sealed properly given the trouble they went to elsewhere with o rings on screw holes, clamps on cable glands and rubber buffer for the button. Perhaps the silicone was expected to go into the rim when the case is closed? They put a fair bit in and its obviously extruded when the case is assembled. I wouldn't wonder that when enough was used in production it came out the sides and the volume was reduced to save cleaning up. It that was the sealing 'mechanism' it wasn't really in line with the engineering elsewhere. I have expected a ring seal really. My early Ctek had a flat gasket but it was crimped in one place so probably didn't work 100% - not that I left it exposed to the elements. It was in a tent garage rather than indoors and eventually blew up. Thanks again for the repair. I suppose it would be easy enough for an owner to open the case on their Noco and seal it back together if the were thinking of using it outside. Obviously that would invalidate the guarantee if it failed though 😡

Pleased you found it useful. This one leaked at the seal between the upper and lower housings. On the NOCO 2 it had a bad leak around the label as it hadn't been fully pressed down at the factory. If you have no surveillance and quality sample testing at the factory then faults like this will almost always creep in. The early CTEKS had a peripheral seal and now use ultrasonic welding. Even car manufacturers have problems sealing light modules reliably. I'll do a video that puts the quality of the seal into context.

Before putting the order I googled CTEK and saw the disaster internal design, I don't think will ever buy a CTEK. I am thinking about the leakage, could it be: when charger is working it heats the internal air, creats some presure so some amount of air is presured out first, then when the charger cools down, the internal presure goes lower then sucks the water in. just a guess :)

If the dew point is reached at any point then condensation will occur inside the unit. None of the units I have tested are watertight but Noco have attempted to mitigate the risk by using conformal coating. Leave a CTEK sheltered but in otherwise outside conditions then it fails due to moisture ingress.

You can leave the charger permanently connected as a maintenance charger, Also these chargers are not designed for prolonged loads because they get too hot.

Thank you for your videos! I've been watching them for the last few hours (!). You've mentioned in comments sections elsewhere that you might compare the NOCO2 and the NOCO5 in a future video, but would you expect, in theory, an advantage in bulk phase charging at 2A versus 5A? I haven't heard you address it in passing, so I assume it's not something you're concerned about in terms of improved battery charging or affecting the lifespan of the battery. Is it therefore reasonable to assume that the NOCO5, functioning as designed, is a better option because of its speed of charging, or is the NOCO2 the better choice because it is slower, assuming the charger is functioning as designed?

@razenby

Thanks. The manufacturers of Small/medium car batteries recommend a charge current of 3 amps. Higher currents on low/flat batteries (not over discharged) can cause the exposed areas of the plates to be eroded. Slow is better but faster and slight overcharge might rejuvenate a tired battery, however you wouldn't give a healthy patient drugs with bad side effects just in case they might get sick... These considerations might be knocked into a cocked hat by the car charging system. I believe that as the battery starts t oget a bit tired the car itself accelerates it's demise especially if it isn't driven far enough or often enough to deliver the full float charge. That is when a frequent safe charge pays off.

A beefier charger (3 or 5A) for an AGM battery is probably best. AGM starting batteries can take (need) a higher charge current up to a higher terminal voltage that ordinary VRLA. You might need the higher current at near to the charge termination voltage to give you the best chance of convert excess sulphate build on the plates.

There is no magic bullet for an aged battery - Snake Oil salesmen gave moved onto Battery Charger Sales. You only need a short battery terminal voltage excursion below 11.5 volts to seriously reduce AH capacity. I have little doubt that a regular maintenance charge with full float/absorption will increase the life of the battery. Especially n modern cars that are infrequently used or used only for short journeys. However when the damage is done modern VRLA batteries do not respond well to so called 'repair' therapy. Being stranded with a flat battery is no fun so personally I would invest in a lithium starter pack or a new battery. However a quality charger will prolong the life of your car battery if you have the discipline to use it.

Hey magic, my battery is now 5 years old and if the car stays sit for a couple of days, it usually gives what I consider a slowish crank and sometimes if I don't drive the car for 5 days or more the crank is even weaker like gives a very slow crank like it's dying then wakes up. I was thinking of changing the battery but someone recommended me charging the battery instead. The battery is a varta blue 60ah 540a, I was going to buy a ctek but since I saw your videos I decided to lean towards the noco but I'm not sure which one is better for me, the genius 2 or 5, there's a 10€ difference right now. Or should I just save that money towards a new batttery ? Thanks.

Great video thanks. I wonder why lots of chargers like Noco are completely sealed and have no fans or at least some big vents plus bigger thicker heatsinks. My guess is very few people truly needs a water or moist resistant charger. Heat is enemy of fine electronics. The moment a circuit gets hot then performance is compromised. These are smart chargers that needs to take decisions based on measurements. I dislike this tendency of chargers completely sealed and electronics crammed inside. Maybe they want them to fail the sooner the better so we buy another one. I measured temp on a Noco 5 charger putting temp sensor right on one screw then it measured 67 Celsius.... Imagine the temperatures inside the crammed space.

@razenby

Dew point condensation is the problem. Vents help cool the internals but also let the moist air in. Temperature cycling of any dust-proof enclosure causes it to breath. If it breathes in moist air and then you will get condensation when the temperature drops to the dew point. The only way to prevent this is to have a hermetically sealed enclosure. Mots manufacturers don't recognise this fact so they fail to conformally coat the electronics with waterproof lacquer.

I suspect the 'silicone' goop you found between the under board heatsink and case floor is to improve thermal conductivity from the heatsink to the case (rather than provide waterproofing). The strengthening ribs on the inside of the case would otherwise cause a considerable insulating air layer between the flap /extension of heatsink and the case. Maybe you could test the thermal conductivity of the 'goop' to see if it conducts heat well?

Fuse is good, and behaves the same when connected to a different battery. Seems to be cycling in and out of standby mode. Still under warranty, so I paid to mail that one back too.

Although it is getting quite hot but charges normally and keeping maintenance charge between 14.38v to 12.86v and I’m leaving always connected to my 45Ah, CCA 285 battery for two reasons - not driving much, and added dash cam that drains about 500ma from the battery.

Purchased in 2012, used about 50 times, never left connected to the battery indefinitely as their manual claims. So, I would never know if it was a defective charger or happened afterwards. I learned about it lately for above mentioned reasons. That is why I purchased these new chargers. And finally, this is what is going on with G7200 - leaving connected to the battery for about 12 - 17 hrs. G7200 goes on stand-by mode. I tried many times but it keeps doing the same. I wiggled the wires when it was working normally - everything was normal. And one more thing, this charger on maintenance mode keeps the voltage between 14.23 - 12.53v never charges 14.4v to 12.8 as their manual claimed.

Is there any chance you could do a summary of ctek vs noco? I'm in the process of deciding between them now.

@razenby

I have kind of done that but it is long winded. I decided to present the evidence and let you decide. Since you are asking, to summarize: CTEK: If you want a battery charge that isn't very reliable and cheaply made, but can be effective with slightly sulphated wet lead acid batteries (not modern VRLA Starting batteries) , then buy a CTEK. Keep it dry and away from dew point crossing conditions. Don't leave it plugged in for long periods because mains transients will end it. NOCO: If you want a much better quality of design and manufacture, and a charger that is good in damp conditions, and you want to charge and to support for long periods then the NOCO is a better choice.. The Noco has higher accuracy voltage sensing and temperature compensation.

Hello everyone, I have a question. Do you think it is possible, for example, in noco genius pro 50A to make a smooth current regulation without changing the voltage? This charger has a switch for 10A max, I need for example from 1A to 10A. Is it possible?

They say so. It doesn't state how long it will provide the full 50A without overheating. It just says 12V supply mode for ECU flashing and diagnostic testing. It will throttle back the power output if the charger gets too hot. What have you got that needs a constant 50 @ 12.6V?

@@razenby I need a reliable car battery charger. Now I have a Ctek msx 10 but it broke. I took it apart and saw that the quality does not match the price. In addition, the battery charging algorithm of this device is not capable of 100% charging. I want to have a reliable universal charger for batteries of different capacities. I like the way Noco Genius devices are made, it looks very reliable and of high quality. I do not need 50A, but I think this current adds reliability to the device. Charging acid batteries is recommended 1/10 of the capacity, but if the battery is old, then you can try to restore it. This requires a current of 1/20 of the capacity or even less. For a 12V 60A / h battery, a current of 6A or even 3A is needed to restore the capacity. If I connect in parallel a variable resistor to the + - output of the charger, can I regulate the current, for example, from 1A to 10A? Do you understand me? Sorry for my English.

The Genius 2 is good for cars and motorcycles. The 2 will charge a larger battery more slowly (it will take longer). The battery manufacturer's data for many 70Ah car-starting VRLA )Valve-Regulated-Lead-Acid) batteries recommend a charge current of 3 amps. If you aren't in a hurry then 2 is a good buy. We have an infrequently driven V8 Jaguar with alarms and keyless entry and I use the version 2 Noco to support the battery 24/7. The battery is good but the car discharges it if not driven for several weeks, It also charges my Range rover just fine too. If you will be in a hurry then buy the 5.

Hello Magic Smoke, I purchased a new AGM 12v Interstate battery: CCA 410, Ah 41, RC 75min. I cleaned the posts with wire brush and started charging the new battery before connecting to my 08 Prius. Before charging I tested the new battery with Ancel BA-201 - SOH -100%, SOC - 88%, CCA - 423A, STD - 410A, R - 5.88-ohm, VOLTAGE - 12.53V, GOOD BATTERY. I connected my NOCO G10 charger and started charging using AGM 12v mode. It took 16 to 17 hrs. to fully charge the new battery to 14.91v. then, I discharged the battery to 13.08v and charged it with the same charger and this time it took 7.5 hrs. to fully charge to 14.91v. NOCO G10 manual says for 40 Ah battery charge time is 3 hrs. What do you think the charge times that I described above is normal or there is something wrong with my brand new G10 charger? Right now, I connected 30ma load to drain the battery about to 13.08v and charge with CTEK US 7002 using the same modes - AGM, 12v to compare the charge times. Can you advise please? Update: today CTEK finished the charge. It took 1:20 to charge from 12.9v to 14.78v. Happy Easter

Hmm, I take the charging stats and almost everything in the manual with a pinch of salt. The fact that it is AGM then it will tolerate a higher current during the last stages of float or absorption charge. To fully charge a battery to max available capacity (without denigrating the plates) you need to carry out this low-current low-speed final stage float charge, This is unlikely not be completed within in 3 hours. If this is a car starting battery then don't ever drain it as they are designed to be drained. In normal operation is will be a quick blast on the starter and then off you go. every time you take it below 11.5 volts a degree of irreversible damage will be done.

The circuit of the power components in the manufacturers data will be very similar to the implementation on the product. You will have to change the PWM chip, the components in the gate drive circuit and check the snubber/flyback diode, the bootstrap supply diode and the current sensing resistor usually in series with the FET source and the AC 0V rail. Good luck.

The Explorer 500 wouldn't support the NOCO for long. Maybe a week. The Explorer batteries would quickly deteriorate if you discharge them fully. You would be better off putting a small solar panel on the shed to provide top up. A controller would be required. An even better plan would be to simply charge the battery every 3 or 4 months. A good battery left alone with no discharge current will look after itself and just need a charge quarterly. Is it possible to run a mains cable to you garage? Probably cheaper than the explorer and will last for ever?

Very much enjoy your videos. I was wondering if your chargers were warm or hot before you started the water ingress test? Perhaps the industry standard / factory tests permit (read 'cheat'), the internals to be chilled / cold-soaked to temperatures well below ambient air / water temp before testing ? (thus air would be escaping as the air inside was warming up while being sprayed). I suppose a possible reason for keeping the case very small and cramped, is that a bigger case would mean considerably more air volume inside and thus more water vapor / liquid water would be sucked in as the air inside contracted each time it cools.​

@razenby

Room /garden temperature. If you warm them up then it can make ingress more likely. However they leak like a sieve. The CTEK blew up immediately I turned it on. The NOCO worked OK because it has silicone and a conformal coating on the electronics and a sealed tact switch. The CTEK does not.

Higher current chargers are best for large batteries. The manufacturer's recommended charge current is nominally 5 per 100 Ah of capacity. Regular charging from a health but low discharge state with high bulk charge current will shorted the battery life.. However the occasional boost can help condition the battery by eroding the electrodes and undermining light sulphate build up. If you have the occasional need to going fast and need a shorted charge time then buy a bigger charger.. If you just need long term battery support then buy a reliable smart charger with temperature compensation. If you are cycling a battery in leisure situation the refer to the manufacturer's specification for the battery.

Understandable, have a nice day.

19:44 When charging a car battery everything should be turned off in the car. In modern cars (2000 onwards), you should always close the doors, lock the car, and wait 15 minutes for all the Command Units (Engine, Infotainment, Doors, ABS, etc...) to turn off completely. On some cars, you can let the doors open. In that case, you should wait up to 20 minutes for the entire system to turn off. Only after that off state of every Command Unit and light can you start charging. During the charge cycle, you should not unlock the car, open a door, or even turn on a dome light. If you do so, you can simply trick the charger in the reading of the battery voltage (making the charging process not linear), or even fry your battery. On the case mentioned, the charger fried itself - which is better than having a fired battery (that we are trying to save), or worse fry a Command Unit. I usually park my car, lock it, and go get the charger. During this time, all Command Units can turn off completely. Afterwards, I leave the battery charging over night; when I know I will not be needing it. This gives the charger the opportunity to do its thing without me interfering.

If you have the exterior lights coming on each time you unlock the car, you can imagine. This amount of Wattage (divided by ~12.4V to have current in Amperes) should not be discarded lightly.
