Working battery detected, but Laptop will not run without A/C adapter

[aPanzerIV]

I have a Dell Lattitude D610 running XP Pro. The laptop will not run without the A/C adapater in place, but yet the LED's on the battery suggest it is fully charged, even without the battery in the system (suggesting the battery is holding a charge). The battery is detected in the bios, but as soon as you pull the plug, the laptop dies, the battery still reads fully charged.

TL;DR: Battery Detected and works, but doesn't supply the system with any power.

Did you happen to recently replace your AC adapter?

No, the A/C adapter appears to be the origional 65w genuine Dell adapter

If the battery wears off, it's not gonna hold any charge at all or it'll hold a very tiny bit of it. Have you checked the battery using batterycare?

No, but I am positive the battery holds a charge. You can take the battery out and hold the led indicator, it says it is at a full charge.

It will indicate it as full charge, based on how much is even available on the battery. It does not account for wear, so technically it can just have enough power to power a light bulb for 2 minutes and it would still count as fully charged.

I'll test this out with my multimeter after leaving it out for the night. How long should it take to discharge the battery without it being used?

A rechargeable battery can last for months if you let it sit unconnected. I don't see any reason to muck with the battery because you can get dirt cheap replacement batteries for the D610 on Amazon.

$14 and it lasts about 3 hours on light-medium usage (I bought one of these awhile back.)

The Latitude D610 is a 2004 model though, keep that in mind.

At that age the battery is very likely to be unable to supply the laptop.

Here is a video of the issue. The battery works and the laptop detects it, but it won't supply it with power.

You can mute it if you want, I put in music to drown out a conversation in the background.

Just buy a new battery, they're dirt cheap.

If the new battery doesn't work, the battery circuitry on the motherboard probably failed in some way. The D6x0 series wasn't known to have the best build quality.

I tested the laptop and the battery today with a multimeter. I found this online;

If this is true, than the negative feed inside the battery does not work. I will find out how to dissasemble the battery and fix this.

As for buying a new battery, I don't have any money, this laptop isn't actully mine, and I much rather tear shit apart and fix it myself for half a day then just wave my wallet at shit to fix things.

Edit: the origional site does not like being linked to, so I just reuploaded the image on imgur.

Double Edit: The laptop's side looks normal and produces a charging current to the battery when the A/C is connected, the battery also produces an output current of 7.5 volts or 3.5 volts depending on which daisychained dell clusterfuck pair of cells I touch. The issue appears to be on the circuit board of the battery. There is quite a bit of corrosion on the contacts which I have managed to scrape off, but it still does not work.

Ill save this battery in case I run into one with dead cells, maybe resolder that ones circuitboard to this one, It's not mine though and it could be gone by then.

Thanks for the suggestions guys!
