Windows 10: Very odd Acer battery situation

The Acer netbook originally had a battery of model number AC14B8K. I bought one that looked identical and was lower priced, with a model number of AC14B3K (Notice the 3 instead of 8). I plugged it in, it didn't charge.

There is a battery reset button on the motherboard and near that there is another button. The battery reset button is accessible through a small hole on the case though the other button is only accessible with the case removed.

If I hold down that other button, the battery will begin to charge and the orange battery light remain solid to indicate such. If that button is not pressed down, it will stop charging.

Do you know what that button is, why it causes the different battery model to work when pressed down and a solution to get the battery to work without that button being pressed down?

What if the battery unremoveable? Should I disassemble and remove it? also there is a switch underneath the case and around the RAM slot that prevent the laptop to turn on when the case is open and without the charger. Is that the same as removing the battery? although when turned on with charger, the laptop still see the battery. Thanks

I took the report, the design capacity was 41.440 mWh but full charge capacity is now 25.752 mWh. Is it that bad? Before this happened I believe HWMonitor also show the same number with 38% Wear Level.
Here's the report file

 

Acer Recalls 27,000 Laptop Batteries

considering sony made all the defective batteries, why hadn't sony taken the step to contact all buyers about potential risk and insist on an immediate recall of all defective, and possibly defective batteries..oh right, they didnt wanna "waste" the time and money...


Regardless if sony knew about the potential problems (though if they did and still decided to ship them they would have proven to be more negligent than ever) they have the exact production numbers, know how many batteries went to which buyer, and how many should have been recalled. I dunno what legal obligation sony has/had to contact its customers about the issue, but the fact is they would rather say "everything is fine" and let their image go down the toilet than admit they had a problem and are willing to do everything in their power to fix the problem.

It is a shame that more companies are not on the ball with recall lists, but the fact is the manufacturer should be the one putting in the extra effort, not their customers, and certainly not us...
