@a funyun this is why the internet was invented.

I actually rebuilt the battery for my ThinkPad 701C myself. You can do it without a spot welder - all you need is a decent soldering iron and some strong flux. It makes it much easier if you sand down the smooth contacts at the end of the battery, apply flux, and then tack the solder directly to the battery. It should take without too much effort, and after that it's just a simple solder job to attach the wires. I've done it many times being lazy (don't want to wait for shipping) trying to connect a cr3032 to the existing ThinkPad CMOS battery cables that I've pulled off the dead one. The sanding down of the surface is a very critical step or the solder will not take. Those ones also get pretty hot pretty quick. But still as a warning, too much heat can make a battery go boom. You'd probably have to go at a (larger) battery for an extremely long time for anything to happen, but warning included in case.

I'm just imaging Clint sitting at Starbucks surrounded by Macbooks and Ultrabooks using his Thinkpad 380.

On battery meter thing: It likely calculates the capacity based on the exact voltage the battery is putting out. The cells in this "new" battery probably have much less droop and stay at a fairly consistent voltage (whatever your laptop expects for 80%) for most of their charge. And then sharply drop off. I've run into this with many devices over the years when powering them with completely foreign power sources. First time was back in the early 00s when my first cell phone's battery died and I modded it to run off AAs. It'd report being at full charge for most of its battery life and then show 1 bar of battery 5 minutes before it died.

There are two kinds of people who tell people to "rebuild the battery!" 1.

Everyone who watched someone do it on KZread, and barf it into the comments section whenever a bad/non-functional battery comes up. IT AIN'T THAT SIMPLE! At least it isn't on the super old stuff, and I don't want to hear anyone say "it was super easy!" because it isn't. Even changes to battery chemistry can make the charger report wrong values--or if it even does that at all, it might be stupid and just charge at a constant (wrong) currant and/or a wrong end-voltage as well.

@eDoc2020

If your replacement cells are a compatible chemistry it _should_ just work. The biggest thing getting in the way is the smart protection circuits on modern batteries. In most cases the capacity reporting will be way off, like it could drop from 100 to zero in ten minutes but then keep working for hours on zero. Unfortunately this is more than just cosmetic, as usually laptops will refuse to boot if the battery reports itself as discharged. In other cases the controller will permanently disable itself if anything abnormal is detected. In these cases you _could_ reset the chip except there is approximately zero public knowledge on how to do this and it varies greatly between different batteries. And that's just some electronic issues which can happen after the swap. There's still the issue of safely performing the cell swap itself without destroying anything. But one thing I will disagree with you on: simple cell swaps are more likely to work on older stuff, not newer stuff. Old dumb Ni-MH or NiCd batteries don't have any smarts to fight you, and I think earlier smart batteries tend to be more likely to automatically adapt to new cells.

Then, just write a simple VBA program which will just decrease the "battery percentage" linearly with time, so that it reaches 0 by the end of the time period measured above. Not super accurate for sure, but, given that those CPUs did not throttle and always worked at full speeed, it might be reasonable to assume that battery discharge speed was more or less constant. For bonus points, the script could adjust the timer based on CPU load, if the relation is still there :) I hope it makes sense!

@jdslyman That feature was introduced when Lenovo took over. I _think_ the T60 and T61 let you limit the charge but the T400 definitely does.

I used to rebuild batteries for years, including these. Some batteries needed the board to be "reset" to get them to report correctly or even work at all. It involves shorting across some contacts on the board with a volt meter. It's more like glitching it than resetting it, but it works. Honestly, it's not worth the trouble unless you really need it to report correctly.

Clint, Usually to re calibrate the battery meter on a laptop you do the following: 1: Charge the battery to a full charge 2: Unplug the charge cord and run the laptop continuously until the battery runs out and the machine shuts off 3: Plug the power supply back in and just let the machine sit untouched and charge the battery back to a full charge. Once you have completed these steps the battery meter should be properly calibrated.

Clint invented a new level of difficulty in Doom that reads: playing outside, on the original 1997 computer under the sun's rays, cobwebs and flying bugs, let's see who is now the "king" for "Doom"!

Rebuilding a battery is no easy task, that is for sure. Not something for 99% of us.

Now you can truly enjoy the great outdoors!

The battery remaining percentage is determined by cell voltage. As a battery Is depleted the voltage decreases. If it’s an older battery it’s possible that it just can’t produce those high volts anymore.

I have a gateway 2000 colorbook2 that came with one of those batteries and it has always worked great which is nice. I have noticed that it only goes to 75% and then when it starts to die it will say 25% so i think it just is the way some batteries were calculated back then. It can last up to two hours which is nice.

Transflective displays are a mix of both and can be used in the dark or in bright light except they generally aren't as bright in either situation. These used to be common in older phones and MP3 players with color screens, but are rare in newer devices (likely due to cheap high-efficiency LED backlights). If you want to run a modern LCD in the sun the "best" option is to remove the display's inner foil and backlight the screen directly using the sun.

Usually the charge circuit creates and maintains a charge profile to display an accurate reading, but to get it to a reasonable level you should give it some somewhat complete discharge and charge data so it does not have to guess, so just sacrifice some of the limited charge cycles and fully discharge and charge it 2 or 3 times in one go, then it should give you an accurate percentage, and as a bonus it would often last longer before cutting off. Usually recommended this back when I sold and repaired computers, and it does work at least for the Windows 2000 to Windows 8 laptops I have experience trying this with. I think it was called training the battery.

Good times :P

battery charge level is measured by the voltage the battery puts out, as the battery charge decreases the voltage does too, for a 3.7 volt lithium ion battery fully charged generally means around 4.2 volts and 0% generally means around 3.0 volts

I've never found older laptops to have accurate power-meters. Honestly, I think it was the way they measured the power-level of the battery back then -- it would hang on some not-quite-100% level forever, and then just drop like a rock after a couple of hours. I've had several late '90s / early '00s laptops that did that. I think it's just the nature of the beast.

Old laptops can be pretty wacky from a power management perspective.

I'm gonna get me one of those for my 380ED!!! Thanks!!!

I find it funny that the game you're testing it with is doom. Way back in college when I picked up a pentium 2 toshiba laptop doom was what I ran to benchmark the battery. 45 minutes.

I got a new (if you wanna call it new) battery for my Dell Inspiron 4000 a couple of weeks ago on sale for 30 bucks (normally 50) just so I wouldn't be tied to the wall either. Gives me about two and a half hours on a full charge which is pretty awesome for a 20-year old machine.

I had a 380XD in the mid 2000's and the battery on it was still good, I had good times playing half-life, nfs3, divx movies on CD and flash games with it until the backlight died, I sold it to a classmate for around 50$ if I remember correctly. Also had a 380ED but it was just not the same.

Usually for the battery meters, run the device till fully discharged, charge fully, repeat 3-5 times

I want to make it known that I liked the video after I cracked up to the fact that clint almost strangled himself with his mic cord xD

I have a Samsung Chronos and there is a setting for the battery to cap the charge at 80%. The premise is to make the battery take more charges over time and hold up better...

You've probably already thought of this but did you notice the screen go dimmer when your unplugged the mains? That's the software power saving kicking in. Fiddle with it and you'll get it a fair bit brighter outside. Whether it makes enough difference, I don't know. But yeah, software AND hardware brightness controls on that thing.

I found an unopened battery for a Compaq LTE Lite a couple months ago. It was from 1997 but it held a charge like it was new.

You know oddly enough I had been "servicing" a Think pad for a relative until they finally decided to upgrade until last year. Didn't really occur to me that the model was so outdated. I guess there are newer models but yeah, it looks strikingly similar.

Regulations forbid shipping a fully charged battery. From what I remember, there was a tool out there to resync batteries. Used to run it on an Acer i bought from HSN for 5 easy payments of $200. I think to recalibrate it… you have to drain it completely… and charge it back up completely… and drain it completely… maybe do this about 3-4 times and it should be calibrated… going back to my days of computer repair.

Battery calibration issues are par for the course with most replacement batteries - but then it is exactly the same with old batteries that still hold a charge, many of those don't fully know what their calibration is even after several cycles. And at this point in time, it is very hard to judge how much is the battery, and how much is the laptop's internal circuitry as well.

As others have said, you may need to calibrate the new battery before you will get a accurate charge remainingreading from it. Try discharging it fully then recharging it fully.

The battery percentage is measured from the voltage (as you probably know), but the voltage drop is not linear, It drops quickly from the 4.2V per cell maximum down to about 4.1V then drops slowly down to about 3.7V and then drops quicker down to around 3.1V at which point the battery is pretty much empty. I guess these older devices are reporting the raw battery percentage without applying a curve to account for the non-linear voltage drop, so the percentage reported is never going to be as accurate as we are used to from newer devices. The exact curve of the voltage drop differs between different models and brands of battery as well and maybe they just did not tune it for the specific batteries they used.

Why doesn't the replacement have the metal bonding strips?

I have two Compaq Armadas (1750) from the late 90s. The batteries each last just over an hour. Agreed on replacing the cells - I tried it on my 4/25 LTE and it... yeah it's still not done.
