Acer Aspire V5 573g Battery Not Charging: Possible Solutions & Home Fixes for 2-3 Year Old Laptop

Hello,

The laptop is about 2-3 years old. So far it has worked flawlessly, but yesterday it turned off / went to sleep while working on the battery, with about 15% charge.
He did not want to turn on again without power, it turns on on power, but the battery is not charged.
Disconnecting the power supply immediately turns off the laptop. Without power, it does not start.
The power supply is functional.

I tried different things that helped people in similar case, nothing helped
Uninstalling battery controllers, removing battery and full reboot, bios reset, leaving laptop without any power source overnight.

Any suggestions what I can do at home, apart from changing the battery?

Either something is wrong with the battery, or the battery control circuit on the motherboard has failed.
If the BQ735 is there, it may be his fault.

Look for the LA-6582P schematic

I think it's probably the battery's fault. While DC and FCC are almost equal, the controller may have disconnected the charge due to the charge meter being exceeded. There may also be voltage differences across the sections. Exit - Have the battery checked by someone who is repairing the batteries.

It looks like it was a battery after all.
The new one works and loads, but there are 3 "problems" with it.

1. The declared capacity is smaller, instead of 3560mAh it is only 3000mAh. Is it possible that the computer misrecognizes this value (Linux and Windows give the same reading).
2. After charging to 100%, for about half an hour the battery continues to charge, and the charging speed systematically drops from 25k mW to about 5k mW.
3. After discharging to about 5%, the computer turns off and won't turn on again, on the battery alone. Again, the system does not matter, after turning on the power and unplugging it, the computer immediately turns off. Is this normal behavior? Is it a battery error or some hardware protection from Acer, because I noticed that it charges the battery only when its capacity drops below 95%, otherwise it treats it as full (tested on two laptops with original batteries).

Battery replacement?

Yes, battery replacement, good German made in China ;)

Point 2 resolved after one complete discharge and charge cycle.
Item 3 also, from what I read is normal behavior.

Point 1 remains, is it even possible?

You can try to calibrate the battery, but I don't think it will help. Probably noname cells do not have the declared capacity.

Thanks for the answers
In theory, Sanyo links, at least according to different programs.
They all read capacity identically, hence the question is how does the computer determine capacity and is there a possible error?
Overall, the battery performs very well.

If there are sanyo cells in the battery, the largest capacity known to me (sanyo GA) is 3450 mAh.
Therefore, the capacity of 3300 mAh is approx.
Then try calibrating twice.
