Some Primary Performance Parameters About Laptop Battery

As we all know, laptop battery has some primary performance parameters like rated capacity

, dominated voltage, charge rate, resistances, lifespan and self discharge. These figures are common to us when purchasing a new replacement. However, how can we figure out the performance of laptop battery from such information?

Rated capacity of IBM Thinkpad battery

Under the conditions of designed temperature and voltage, laptop battery can release capacity in minimum with unit of mAh(C). To be sure, the capacity has been influenced seriously by discharge rate, such as C20 which is equal to 50mAh. IBM Thinkpad battery has its own features in this field of capacity so that it can be calculated by dosage of active materials of electrodes and electrochemical equivalent in reaction formula. Due to side reaction and some special needs in design, laptop battery has lower actual capacity than the theoretical value.

Dominated voltage of IBM Thinkpad T30 battery

Dominated voltage is determined by typical work voltage at normal temperatures, which is selected by different sorts of batteries as a reference. Normally, the actual voltage comes to be different from each other with different service conditions. In open circuit, laptop battery has voltage of D-value in equilibrium electrode potential between anode and cathode.

The voltage of IBM Thinkpad T30 battery is just DCV in itself while it is closely related with materials of electrodes instead of quantity of active substances. In some special conditions, metal particles caused by electrode reaction are likely to arouse tiny fluctuation which is called noise. As the range of fluctuation is small with wide range of frequency, it can be separated by self-excited noises in the circuit.

Rate of charge and discharge in IBM Thinkpad battery

Sometimes, it can be expressed by time rate and multiplying power. Time rate can be used to show the rate of charge and discharge by time which is calculated by rated capacity and hours. Meanwhile, multiplying power has the same value as count backwards of time rate. Laptop battery has been influenced seriously by charge and discharge rate so that it is significant to reach this conclusion on the data.
