            How does the laptop batteries work

Laptop batteries are complicated pieces of equipment. They are somewhat redundant as well. There's a 'smart circuit' in the hp pavilion dv6100 battery pack that monitors the conditions of the battery cells, however, it does not do what a lot of people say it does.

The image below is a typical smart circuit. It has four wires running out of it: ground, power, and two 'intermediary power' wires (actually the ground wire is just the tab on the right).

Lithium cells output about 3.7 volts. Like all batteries, in order to increase voltage, they are connected in series. However, charging a "pack" by adding power through the positive node and negative node of the whole hp pavilion dv6500 battery pack is dangerous. They are not guaranteed to charge evenly (refer to resistance in series in a physics text). This means one cell may overcharge and explode, which is very bad especially since it's lithium. The intermediatary power wires are sandwhiched between every series connection of the battery pack so that it monitors each individual cell.

Laptop batteries are made with lithium ion/polymer or nickel metal hydride. No matter which kind of hp pavilion dv6700 battery is in a laptop, that battery will not last forever. When a user plugs the power cable into a laptop, the chemical process of reversing the electrons back to the first terminal begins. This action is normally fine, unless the laptop battery has been nearly drained. A full recharge on a typical laptop battery can be done several hundred times before the battery needs to be replaced. Things that can drain a battery rapidly include using the brightness at full capacity and playing movies from the DVD drive. Video games can run down the hp hstnn-c51c battery, especially if the game requires a CD to be in the drive during play.
