Laptop batteries work principle

General electric batteries use core notebook is 10.8 V or 11.1 V, and a single battery can't satisfy requirements so notebook computer batteries are using more monomer battery series and parallel composition of the battery. As for everyone in the exterior of the battery often see 3300 mAh, 4400 mAh etc refers to the capacity of the battery, it is the indicator of the current for battery for electric discharge can use the one hour, for example: 4400 mAh of lithium battery can to the mA's current discharge 4400 an hour. So the values the bigger the better proof it can work time is longer.

Charge and discharge control and protection circuit just as its name implies is responsible for the battery charge and discharge control and protection, it is this principle of work PANASONIC Lumix DMC-FS3 Charger, because of lithium battery during charging to very close to full of voltage of a slight fall a bit, so control circuit testing to the situation that the battery has filled with, the protection circuit also cut off the power supply work to prevent overcharge; When the battery voltage is discharge basic stability constant, only in the battery left little power will be suddenly slumps, when the control circuit testing to the situation that the battery power out and notify the protection circuit cut off power to prevent excessive discharge make battery life for short. The laptop batteries, the internal structure of actually simple of impending, a shell, a work circuit and a battery.

Remember this battery basic is the battery is mainly battery joke + circuit board + core, it looks like the most important part of the core is, in fact, is the most important part of the circuit, because a battery of use process itself, is recorded in the circuit board. Maintenance a battery, if simply replace corePANASONIC Lumix DMC-FS25 Charger, it is useless, because the battery on the stand or fall of itself, have been recorded. So if you have to ask if the battery maintenance, will find a unlock the words, in fact, is that the relevant records will be locked circuit board of the battery replacement information, such as the number and use time charging, etc to set, plus all the good of the core is tie-in, will achieve new battery with the continuation of the time. These are behind us part of the maintenance to explore the content.
