subject: Questions On Laptop Battery From Rookie-1 [print this page] One friend got an IBM Think Pad (42T4504 Laptop Battery
); he came to ask me about how to maintain the battery. He posed a lot of question that we often encountered. That strikes me to write something about the commonly misunderstandings of laptop battery. Last time we mentioned three points. Today we are going to continue this topic, just take this 42T4504 Laptop Battery for example.
The battery requires periodic calibration, its necessary to charge and discharge completely once a month?
For Ni-MH battery which has strong memory effect, this is essential. But for the lithium battery, it is too frequent for the lithium batterys memory effect has greatly reduced. If you use the battery too often, then you should discharge to about 10 ~ 15%, and then recharge. But if the battery can not boot, the lithium battery will have damaged by the discharge. So generally it should be done once every 2 months. For those who use battery too frequently, take this as long as once every 3 months.
As this 42T4504 Laptop Battery, my friend has it at home for entertainment use. So he can discharge once half a year.
The battery capacity can be raised by the calibration?
Calibration is when the batterys actual capacity is not the same as the record capacity of the control circuit, have the battery charge and discharge completely so that control circuit record refreshing which is a manifestation of the true capacity of the battery operation rather than enhance the capacity. 42T4504 Laptop BatteryHere should notice that the calibration is to reveal the real capacity and remove the gap between battery and control circuit. As the capacity demonstrated increases or decreases is the state of the battery itself. Its not determined by your calibration.
According to the description talked above, I suggested that his 42T4504 Laptop Battery should follow these tips.42T4504 Laptop Battery
