At laptop, the laptop battery is a love-hate parts, it gives the laptop the ability of mobile use, but often continue to work compared to days or even week-long mobile phone and the MD, the notebook’s battery time remains a tooth If the cell phone battery can only use eight hours, ten thousand people will surely be reviled, but such a score in the laptop already outstanding are proud to say laptop in the development of the slowest parts, except the keyboard should turn the Inspiron 9200 battery , and that there is such a joke:
Intel’s investment and technology through participation in support of the new Latitude D620 battery technology, “For us, the lithium batteries in the 1990s have been good enough,” director of marketing for Intel’s mobile platforms, said Mooly Eden, “Improvement of the battery is like a teenager the relationship between young people and the same: Each person talking about, but no one has done. “
Battery maintenance has been a laptop user’s hot topic, but in fact there a lot of misunderstanding, in the final analysis are from two aspects, one is “thinking has not kept up with nickel-metal hydride batteries to lithium Inspiron 5000 of changes”, while a more comedy, from the mobile phone, mobile phone because most users are in fact the earliest use of repeated exposure to a rechargeable battery of equipment, so will take it for granted a number of mobile phone habits put into the laptop body.
I did not intend to put the majority of notebook users trained experts, that there is no need, thinkpad r40 battery , I just want to put some of the most vulnerable to clarify the misunderstanding and give the correct perspective and practices.
Thinking behind the changes in battery
Misunderstanding 1: Laptop bought three required repeated charge-discharge in order to activate the Sony battery .
Unless you buy the laptop for more than one year are the product inventory, or need not do so, because now the battery batteries at a time when the factory has been activated, and the batteries into a package at a time when notebook batteries PCGA BP71 , VGP BPS8 , VGP BPS9 , after a equivalent to activate the test, so you get hands batteries, already have been activated, and again three times charge-discharge process was an increase in unnecessary depletion.
Misunderstanding two: first charge must charge enough for 12 hours
This early stage those who do not have the VGP BPS9/B control circuit of the Ni-MH battery models are applicable, but for now has a smart charge and discharge control circuit for the notebook battery is a joke, when the toshiba battery is full, the charge current will be automatically cut , even if you continue to charge 120 hours, state and there will not be changed, in general, even the slowest machine charge, 6 hours completely filled, the remaining “charge” is just a waste of their time. It is time to get new machines should first rechargeable toshiba PA3383U-1BRS .
Three errors: the need for regular calibration thinkpad a20 battery once a month put the total charge.
Strong memory effect for nickel-hydrogen batteries, which is an essential task, but for Li-ion toshiba PA3285U-1BRS battery , the cycle is too frequent, and lithium batteries toshiba PA3399U-1BRS , toshiba PA3395U-1BRS does not completely eliminate the memory effect, but has greatly reduced the memory effect, if you use the battery is frequent, then you should discharge the battery to the relatively low (around 10 ~ 15%) rechargeable, but even if the discharge to the open machines are not (0 ~ 1%), on the lithium battery to belong to a greater depth of injury discharge generally every two months to do such a operation on it. If you rarely use the battery, then every 3 months as long as the first such operation carried out on it.
Four errors: Calibration can be carried out to upgrade the evo n410c battery capacity
The so-called correction, when the actual capacity of the battery and control circuit capacity not the same record, the depth of a battery charge-discharge operation, so that control circuit record to make it closer to the actual situation of the battery, this is a true performance of the Inspiron B130 battery capacity operation rather than to enhance the capacity of the key factors here are the actual capacity of the battery, if the actual battery capacity than the control circuit in the capacity to record high Calibration can make the battery appear to increase capacity, if the actual battery capacity than the control circuit the capacity to record low, the correction will reduce the capacity of the battery looks, which is much debate on the reasons for the effect of Calibration, Calibration Please keep in mind are the true capacity of the Latitude D600 battery is shown by the elimination of the battery and control circuit between the deviation, as demonstrated by the capacity will increase or decrease, this is the status of the battery itself, rather than your Calibration determined. Calibration is very likely because the battery discharge when the depth of injury, but a substantial reduction in capacity.
