Hello everybody,
My problem is: plugged in, my laptop battery sometimes charges and sometimes not, stuck between 93 and 95%, and when unplugged, it only lasts 5 minutes or so.
But, I opened the battery and checked the voltage, which is 16V exactly.
I am clueless, if anybody can help me, it would be appreciated.

Thank you,
Ralph.

Sounds like a dying battery. What voltage is the battery rated for? Also although the battery can deliver 16v with no load does not mean it can hold its voltage while under load from the laptop.
