Battery life explained by <linux_geek>

do u know if it better to keep battery out of my laptop when i am on powersupply Depends on the sort of battery. NiCad: need full charge+discharge. Li-Ion: is quite happy with a “shallow” discharge and constant recharging

I've been told that the best way to keep a battery “fresh” it to keep it in the freezer - slows down the chemical reactions. Unfortunately you can't use it while frozen though…

I never tried it myself though - i like (and sometimes need) the built-in UPS on my laptop…

i know they are limited to 500 cycles full cycles are known to be better it it true ?

500 sounds a bit low… that would make it just under 2 years? Mine are on their 5th year - but they do discharge within 1 hour though… I'm not sure whether full cycles are better or not. There are too many variables in there the manufacturers don't tell….

ni/cad vs li-ion : is usually written on the outside. But the rest of the information: anybody's guess. there is always some electronics involved to avoid over-charging and under-charging. That might interfere with things. Or enforce a manufacturer-specified limit, to force you to buy a new one.

Some batteries have a little bit of non-volatile memory in their circuitry to keep a “history”. But this is nearly always hidden away…
