Four tips for How to Test the Capacity of Your Laptop Battery

In the measurement of battery technology

, there are four kinds common method (open-circuit voltage measurement, Coulomb calculation, impedance measurement, integrated look-up table method), usually using a combination of methods to one of the main method of supporting the rest of the way computing power.

First, impedance measurement, measuring its resistance to get the remaining battery capacity value.

Second, open circuit voltage measurement, this method is that measuring the battery voltage under static values to calculate the remaining battery capacity, but as a result of stationary lithium-ion battery voltage and remaining capacity relation is non-linear, so this method measured valueis not accurate, the vast majority of mobile phone batteries are calculated using this method

Third, comprehensive look-up table method, by setting up a related form, the voltage, current, temperature and other parameters, you can query the remaining battery capacity.

Fourth, Coulomb calculation, the method is by measuring the Toshiba laptop battery charge and discharge current, the current value and time value After the calculation of product integration has been carried out by filling the battery into the power and the release of electricity, Coulomb?s method is a accurate method of calculating power.
Laptop batteries can be 6-cell or 4-cell, meaning that there are that number of battery cells inside the battery. The batteries cells conenect together, the battery capacity reduce reason is that: all the batteries quality and discharge rate can not be in the same level. After discharge, one battery cell capacity in substantial reduction, in order to maintain voltage stability, the battery management chip will be according protection of core power as the ?bucket principle?, so after the electricity charge will decrease.
