Several small knowledge of the laptop battery

The laptop is becoming more and more favorite, is its portability and mobility. It was generally felt that the small size of this thin is better mobility. In fact, not at all qualified to decide whether the laptop mobility, there is an important factor is the battery. Why do you say that? We can imagine, if you buy a small size laptop, but the usage time of the battery is not very satisfactory, then the mobile PC, what difference does it make?

Laptop battery type
First, we have to look at the type of laptop battery. Laptop battery is divided into a total of three ways: 1. Nickel-chromium batteries, nickel-metal hydride batteries, 3. Lithium batteries. Their side: nickel-cadmium NI-CD, Ni-MH NI-MH, lithium battery LI. Mainstream notebook lithium battery.
Laptop battery capacity
A lot of people buy notebooks are beginning to care about battery businessmen who configured single write-only the battery capacity for xxxxmAh the without writing the voltage of the battery, in fact, the real unit is not a reprint of the size of the battery energy mAh but Wh. The battery power is calculated by: a battery power (Wh) = the battery voltage (V) x the battery capacity (Ah). Please note, here Ah battery capacity units instead mAh, 1Ah = 1000mAh. The example the the module battery nominal 10.8V/2200mAh, then its power is 10.8Vx2200mAh/1000 = 23.76Wh. Battery voltage and capacity usually marked on the battery, calculate know. Some vendors will not be marked on the battery specifications, so we can only use the test software.
Notebook battery core replacement
Laptop battery battery inside the core with our usual battery is about the same, just larger. Many batteries are designed with a self-locking function, that is, once the battery from the control circuit will enter a self-locking state. Into the status of the self-locking battery will not work, the battery is tantamount to scrapping, only certain techniques in order to unlock, which only a professional engineer to do. So we can only choose to replace the battery core. Replace the battery core can not be so casual, I hope to find a more professional personnel to replace. If they replace, end-of-life of a battery is a little thing, but did not succeed in the kind of effort to combat the most maddening.
