i want to reset my notebook battery

Hi, I want to reset/revive my notebook battery. The battery never gave good performance even from new. At most I can get about 30 minutes out of it. Does any one know how to reset the battery (not sure if i am using the correct terminology).
Thanks
Maku

 

How new/old is it?

 

you cannot reset/revive a notebook battery.

you need to buy a new one.

check ebay or your contact your notebook manufacturer.

 

If you've got nothing to lose, try putting the battery in the freezer for 2 hours or so. I've heard that the temperature change will refresh the battery a little. Be careful, though, I've never tried it myself (friend did it) and I can't tell you how the chemicals in the cells may react to extreme environment changes.

 

If its under a year it should be 100 persent convered by warrenty. becouse it seems very odd that you have bin gettin 30 min max!

 

If you're talking about recalibrating the battery, then it should be in the bios

 

If it's lithium-ion... do not put it in the freezer, they don't like cold. Lipo's give worse performance in the cold... the freezer cannot help it.

Lithium packs have a much reduced life-span than the old Ni-Cad/Ni-Mh packs... they can go for 1000 cycles or so. The older packs however can go through many more cycles without deterioration... problem with the older packs though is that they developed memory and people didn't treat them right, so they die prematurely also.

...but for Lithium's, you can't mistreat them (well, outside of puncturing them of overcahrging/discharging) in terms of cycles, no memory or whatever... it's just that they have a much reduced lifespan in terms of cycles.

 

This friend of mine did it w/ his cell phone battery and Sony VAIO battery and they gave much better performance after that. But, if thekm says it is not advised, then its probably best to be safer than sorry.

 

Freeze it, then thaw it completely before you use it again. It's the temperature change that affects how it works. It's a last-ditch thing, though, to try to get it working better because it may "shake loose" some of the build-up of the state-changes of the chemical interfaces in the battery. The most important thing is to treat them right initially, charge it up all the way, then discharge it all the way, then charge it up all the way again and then you can start using it "normally". That should ward off any memory effect or reduced performance. Thinkpads recommend that you "recondition" your battery like that every month or two. I do it about every 6 months. Usually use a Linux LiveCD and run some CPU intensive program until it shuts down, so I don't have to worry about losing data on the hard drive to a bad filesystem unmounting.
