how to keep a notebook battery

Dec 2, 2008 8:30PM PST

hi dear all friend,
i have sold laptop battery for a long time, as to the suggestion of my friends, i stand here to say something about how to keep your notebook battery.

people know that battery is expensive, so we should take care of them after we buy them. so how to take care ?

first, when we first use them, we should charger them for a long time (no more than 12hours)in order to activate its capacity, and continue this process for three times. it's important.

second, when use them for a long time, we should let them have a good rest

third, when we use them for some month, we should release their capacity totally and then charger them totally in order to avoid memory offect.

forth, when the PC tell you that the battery has 10% capacity, you can charger now. when it has 30%, continue to use it until 10%.

so if you want have more information about notebook battery, you can add my
MSN: or email to

Sorry but memory effect was NiCad days.

Today your common laptop has LiON, LiPO and newer batteries without that memory effect. Your method would only accelerate the aging and is great advice for those that sell batteries.

hi my dear friend,
thanks for your reply,i agree you in some way!
but i should say that every battery has memory effect, such as Lion.people say that lion has no memory effect, it means that the memory effect of lion is less than Ni-MH. so we should take care of them .
you may have a notebook, so the battery is important, let us take care of them.
if you have more suggestion, just give me email.

No, it doesn't

No, it doesn't... Really. LiIon batteries do not suffer from memory issues like older nickel based batteries did. They will hold roughly the same capacity charge for about 500 cycles before gradually losing capacity.

There is a certain margin of error on each individual charge, but it should be within a couple of percent each time.

you are so cool, you have more knowledge than me on the battery ?
it seems that we have different ideas on the memory effect. so god know it!
some professor say lion is good than nickle, yes, it's good, because so many people like to use lion instead of nickle.
lion is easy but we should take care of the temperature, if the temperature is higher than 80 degree, we should stop it !

The advice given here is erroneous.

There is ample battery research available so I'm going to state clearly that those that sell batteries want to sell more batteries. Some of these sellers give out very bad advice.
