dell laptop battery

General laptop batteries with a battery or 10.8 11.1, and a single cell can not meet the requirements of so many laptop batteries are of the composition of individual cells in series and parallel battery-based. Since we often see in the Dell X284G battery compartment 3300mAh, 4400mAh and thus refers to the capacity of the battery, which is an indicator for the current discharge of the battery can be used for an hour, for example: 4400mAh lithium-ion batteries discharge can 4400mA for one hour . Therefore, the proof of the value, the better the longer it can work.

Charge and discharge control and protection circuit suggests that it is for the DELL Studio 1537 battery charge and discharge control and protection, the principle that it works, because the process of charging the lithium battery to provide a very full, if the voltage drop that something, so that the control circuit detection If this situation is that the Battery full, the work and the power is off protection circuit prevents overcharging, discharging of the HP Pavilion DV7 Battery voltage basically stable and unchanging, and very little energy in the battery is present only when a sudden drop when loop detects this situation is that the battery ran out and inform the protection circuit cut off power supply to prevent over-discharge the battery life shortened.

About the internal structure of laptop batteries, in fact, incredibly simple, a shell, a working circuit plus a battery.

In general, the battery through the adhesive joints bonded together so we can easily find the position of liability, but basically the position of the interface, not powerful tool is not always open.

Decomposed, we can see that the volume is more than 95% of the Dell Inspiron 1545 battery, plus a piece of circuit board

The battery board is mainly shell + + batteries, it seems the most important part is the batteries it is not true, the most important part is the circuit, because the process of using a battery is even recorded in the board. Maintenance of a battery, if you simply replace the batteries, it is useless because the battery itself is good or bad, have always recorded. So find out if we know if the battery have maintenance, you can unlock a word, the castle is actually exchanged in the Board information on the DELL Latitude D830 Battery, for example, the number of charge cycles and the use of time to re-set, plus all recorded core wires of the game, it is to achieve the same with the new battery life. These are some of the repairs to the back of our content.
