1348433 2013-07-10 00:11:00 depends on battery.
a lot of them have counters in them so the battery is only good for 4 years regardless of if its used or not.
the chip in the battery disables the battery when time is up.
not sure about later model ones tho.
best thing with most battery types is to simply keep them charged up and don't let them get to hot.

I have always been advised that you should discharge a rechargable battery completely before recharging. I am told that will extend its life.

Was it a keen battery salesman that told you this? ;)
For a very narrow range of superseded Ni-Cd that was once true. Lithium cells die from this treatment almost immediately. Lead Acid lose 50% of their capacity each time. Basically, Bad Idea.
To store a Lithium rechargeable, charge it fully, slowly discharge it to around 70% and then seal it in a plastic bag (to keep moisture out) then put in a plastic box (mechanical protection) and leave it in a fridge at around +4 deg C. Check the charge each 2 months or so and top up charge to 70% every year or so. However, most Lithium rechargeables deteriorate over time anyway, all the above procedure does is delay the inevitable. More practical long term is to sell the battery and buy a new one when you need to use it.
Most cells, Lithium particularly, benefit from being operated between 60% and 90% charge. So, when plugging into the mains, remove the battery before it is fully charged and operate on mains supply. Whether the nuisance value of this justifies the minor increase in life is up to you.

1348436 2013-07-10 08:13:00 but battery have charging and discharging life cycles ,for li-ion its typically 1000 cycles only,so can we use it with plugged in ashishtc1 (17126)
1348437 2013-07-10 11:09:00 A typical cycle life figure is dependent on using it in a "typical" manner. Typically, these figures are provided by battery and laptop manufacturers who typically want to look better than their competitors, test with slow, shallow cycles. Not actually the sort of use found very often outside the test lab; in fact, it is as unrelated to real life activities as the PCW test for anti-virus performance. The marketing department selects which figures will be selected from the pile.
This means you will not get the results claimed unless really weird things are happening and all the planets are lined up just so. ;)

1348438 2013-07-10 11:18:00 so can we use it with plugged in

How are you supposed to charge it if you can't use it while plugged in? :confused:

1348439 2013-07-10 12:23:00 Rather than leaving the battery plugged into the charger for extended periods of time, remove the battery and run the computer off AC power. Store the battery in a cool place ashishtc1 (17126)
