My laptop battery charge rate is very slow. It charges between 50% - 100% in almost 4, 5 hours. Is it battery or charger problem? I have changed my laptop battery 4 months ago but the charger is 4 years old. My laptop is HP Compaq 6910P (Core2Duo 2.0, 2GB RAM, 80GB Hard disk).

Is it an Original (HP approved) battery, or an aftermarket battery –  Akash Apr 21 '12 at 8:07
    
I don't think its original battery –  Daud Apr 21 '12 at 8:08
    
Laptops (or the batteries themselves) often reduce the rate of charging for aftermarket batteries to increase lifespan and compensate for lower quality –  Akash Apr 21 '12 at 8:09
    
Did the problem start around the time you switched batteries? –  David Schwartz Apr 21 '12 at 9:45
    
The problem started after a month after changing battery –  Daud Apr 21 '12 at 14:02
