Analytical Laptop battery charge and discharge errors

• Misunderstanding number one : the depth of discharge can enhance the battery capacity

Zhang Xin is a SOHO owners, a years ago bought laptop due to frequent on battery power as 85wh apple A1172 Adapter, and now the battery is fully charged, the battery life is only half an hour, Zhang Xin's boyfriend, the computer to understand more , so plan on Battery depth of discharge , he believes the depth of discharge, can enhance the battery capacity , increased battery life. But once the discharge was found , in fact, battery life did not increase , but also to reduce a little bit , because Pavilion DV1000 Battery a reduction of one charge cycle , battery life will naturally decrease point, but a lot of friends there is such a misunderstanding that the depth of Discharge can increase the battery's actual capacity.

For Zhang Xin this case, first of all we know , due to number of charge cycles excessive , the battery in the first charge cycle endurance capacity on the decline, this time due to memory effect so the chip can not properly identify the PA3284U-1BRS battery capacity , there will not be charged Case, battery life less than 40 minutes, we must its discharge operation to repair the battery capacity , but certainly not increase the the battery actual capacity of , because when the first charge cycle the end of , through deep discharge the battery to the next a charge cycle , But each dropped a charge cycle , the battery the total electricity consumption will have a certain decline in , for example, battery deep discharge 10 after will only keep the original charge about 80% of , and the depth of discharge 200 times , the battery may be only 30% , and To 300 charge cycles to come to an end .
Obviously, when the battery the actual capacity of and control circuit the record of capacity not the same as when the battery a depth of charge and discharge operation, to the control circuit record , bringing them closer to the Compaq Evo N610C Battery the actual situation of , this is the battery the real capacity of reflected , not Enhance the battery capacity, although some battery calibration software allows the battery capacity is increased , but this is the software 's " virtual "of promotion, because the battery 's actual capacity is sometimes often unable to and control circuit in record capacity the same , of both the low percentage , Indicating the may be required discharge operation to repair , and when the ratio is high, may be the battery correction software deliberately blur , so to remind everyone that no matter what calibration procedures the battery discharge , and its actual capacity will not be changed Or even lower.

• Misunderstanding of two: long-term need to be periodically charge and discharge

Guo Yue to buy a notebook with more than 3 months , and because it is in the home used , so basically using the power supply, in order to reduce VGP-BPS9A/B battery charge the number of , he will take off the battery put in the drawer , when my colleagues know his situation, and then said the battery Do has been not use , otherwise the battery will gradually fail , and advised him even not the battery , it is best full charge or discharge to take down the place, and preferably month or so, the battery a charge and discharge . Undoubtedly, this is most users think it is more correct battery maintenance of way, if you think to carry out this operation no trouble , and each month to remind ourselves discharge , then to tell you , a waste of time in the same time, some Operation is likely that seem futile , but rather not a good thing .
First of all make it clear that if the
Dell Latitude D620 Battery charged when place a long time not , is likely to as save the environment is not ideal for power loss, then loaded onto a notebook found power did not, then you can charge it to continue to use . However, for battery storage , either charged or discharged, save it with the battery remaining 1% , 30% or 50% of the such power preservation of there is no difference , on the contrary , fully discharged save the will batteries loss of activity , and even lead to the control Circuit protection self-locking and can not re-use , full power long-term preservation will bring security risks , and the A1045 battery save the life of most affected is the high humidity and temperature , as long as the battery on the humidity of 30% to 80%, room temperature 10 ~ 30 ℃ Between place , the basic will not be any problems.
Many users believe that the battery even if is not used , also need a monthly Chedi charge, discharge time, the memory effect of a strong nickel-metal hydride batteries, this step is obviously very necessary , but the lithium batteries memory effect of relatively low , and No Biyao monthly charge and discharge time , too frequent charge -discharge cycles not only a waste of time , but will reduce Pavilion dv9000 Battery life , course, despite the notebook lithium batteries have not completely eliminate the memory effect, but has greatly reduced the memory effect, if Batteries long do not , it is necessary 3 to 4 months charge and discharge time, but not full or complete discharge, if discharge to even laptop is open not , this time belonging to the lithium batteries have greater depth of injury discharge, Often counter-productive.
