Laptop Batteries - How does a Laptop Battery work?
Just like their AA, AAA, and C cell cousins, laptop batteries create an electrochemical reaction that forces a stream of electrons from one place to another. And just like household batteries, laptop batteries have a positive and negative terminal where electrons are received and sent, respectively. However, have unique characteristics compared to household batteries.
1. They are rechargeable
2. The toshiba satellite m50 battery is composed of multiple internal cells
3. They contain a small printed circuit board
4. Their overall shape of a laptop battery and the location of their terminals vary from model to model
Rechargeable Toshiba PA3534U-1BAS batteries are significantly more complicated to design than a non-rechargeable toshiba tecra a8 battery because the electrochemical reaction that provides power must be reversible. As Lawrence Berkeley Lab's staff scientist Frank McLarnon explained to Scientific American.com:
"When a is discharged, an electrochemical oxidation reaction proceeds at the negative electrode, and an electrochemical reduction reaction occurs at the positive electrode. When one attempts to recharge a toshiba pa3534u-1bas laptop batteries by reversing the direction of electric current flow, the opposite takes place: a reduction reaction proceeds at the negative electrode, and an oxidation reaction takes place at the positive electrode.
"In the case of the rechargeable toshiba satellite m60 battery, the electrochemical oxidation-reduction reactions are reversible at both electrodes???In the case of the non-rechargeable battery, when one attempts to recharge the pa3534u-1bas battery by reversing the direction of electron current flow, at least one of the electrochemical oxidation-reduction reactions is not reversible. When the battery is charged, the overall reduction reaction that proceeds at the negative electrode may not be the true reverse of the oxidation reaction that proceeded when the toshiba satellite p25 battery was discharged.
If the laptop battery process isn't exact, then unwanted build up can take place on either terminal over time, which can cause a dangerous short-circuit.
Also unlike a household battery, toshiba satellite pro p200 battery are composed of multiple internal cells. These cells are arranged in series and in parallel in such a way that the toshiba laptop batteries has a higher voltage level than the individual cells. Laptop batteries also contain a small circuit board that controls the way the cells are recharged. Without this board, the laptop battery would not function properly.
