new battery stuck

[5750g]

Hi I need help,

I recently bought a brandnew battery for my Acer Aspire 5750G-2414g75mknkk.and now the charge meter is stuck at 68%.

I really hope you can help me.


Info:
the new battery is not original, but a 6600mAh extended capacity battery.
The charge meter shows: plugged in, charging when power is connected.
the laptop works for a long time when disconnected, but suddenly shutsdown, chargelevel not changing.

I have already tried to reinstall Microsoft ACPI Compliant Control Method Battery

battery 8FFPANASONIC Li_Ion_4000mA < info from powercfg -energy
Design capacitet 71280 mWh < info from powercfg -energy
last full charge 71572 mWh < info from powercfg -energy
voltage 12.530mV < info from batteryinfoview

just some curious info,
12.530mV*4000mA gives = 50120mWh, which is 70% of the designed capacity, can this give a conflict somewhere?

Maybe its a higher voltage battery than your charger is made for.

I believe it is an compliant voltage. its 12.53V at full charge.
(currently 10.87V after a few hours use).
The charger supplies 19V.
The battery accepts a charge , I can easily use the comp without power, until it shutdowns due to low power, at which point I can just recharge it.

Leave it charge for 24hrs. If it doesn't get to full voltage, return it for credit, refund or a replacement.
