How best to preserve access to laptop batteries

Sunday, September 21st, 2008

Yuzhong District of Miss Fan asked: I use in notebook computers is often directly connected to a fixed power, BTP-550P, BTP-73E1, BATCL50L, TravelMate 290, the notebook’s battery configuration is always no access to, I would like to ask how best to preserve access to the battery?

Xiao Bian: You can charge or discharge notebook battery to 40%, and then on 15 to 25 degrees Celsius temperature of the Department to preserve dry, the temperature is too high and too low are easy to speed up the aging ThinkPad R30 battery. In addition, because the vast majority of notebook computers used lithium-ion battery for a long time, if not in use, often prone to “excessive discharge”, may no longer be able to charge for. Therefore, if the laptop battery needs to be shelved for a long time to save,BTP-73E1, then left in the battery to ensure a certain degree of power could be at least a month on a full battery charge and discharge, and then save the above-mentioned methods.

The remaining battery power and then run out of charge to the principle does not mean that you go to the extreme. And charging the same length of a widespread,

“As far as possible the cell phone’s battery run out of power, it is best to use automatic shutdown.” This is only a matter of fact on nickel batteries,

The purpose is to avoid occurrence of memory effect, unfortunately, BTP-550P, BTP-73E1, BATCL50L, TravelMate 290, it is also spread of lithium batteries on this. It has been because the cell phone battery had

Low warning appears, do not continue to use the charge has been used in automatic shutdown of the case. The outcome of this case, the phone in

Later in the boot of charge and there was no response, had to give customer service overhaul. In fact, this is due to the hp PP2182L battery as a result of the excessive discharge as a result

Low voltage that does not have the normal charge of the boot and conditions.

3, Li-ion battery for mobile phones boils down to the correct approach,BATCL50L, I lithium batteries used in mobile phone charging and discharging of the most important tips are:

1, in accordance with the standards and procedures, charging time, even before the three to do so;

2, When the phone prompts when electricity is too low and should start charging as much as possible in a timely manner;

3, lithium batteries do not need to activate the special method, BTP-550P, BTP-73E1, BATCL50L, TravelMate 290, in a normal cell phone use in lithium batteries would be natural to activate. If you insist on spreading the use of “three times before the 12-hour long activation charge” approach, in fact there will not be the effect.

As a result, all 12 hours long pursuit of the lithium batteries and rechargeable cell phone used in automatic shutdown, are wrong. TravelMate 290, If you are used to be in accordance with the wrong done, please correct in a timely manner, perhaps not too late.

Of course, cell phones and chargers to protect themselves and control the quality of a good circuit, for the protection of lithium hp DM842A battery or have guaranteed. Therefore, understanding the rules of the charge is the key, in some cases also may make some concessions. For example, you found your cell phone the night before bed charge, you can also start charging before going to bed. The crux of the matter is that you should know what is the right thing to do, and not in accordance with the deliberately wrong to do.
