Question about HEWLETT-PACKARD Hewlett Packard Battery for HP/Compaq Presario CQ40 (4400 mAh, DENAQ)
You have the same problem as me. Don't forget that batteries have their shelf life as well. After a few years laptop batteries become inefficient and are unable to store the full 100% capacity as storage sectors become obsolete. I had to go straight to the Producer and order a replacement battery for around 100 bucks.
