Default Dell Mini 9 Battery care? what do you do? - 10-24-2010, 07:32 PM


What is the best way to care for the life of the battery? of the dellmini and laptops in general?

This has been my typical usage with laptops in general (and now the mini).

Installed battery and plugged into AC at all times,
Remove from AC to go mobile, battery typically gets discharged to 60% if that
Plugged into AC again - battery goes to 100%
Keep using it with both installed battery and AC while on desk (doing work/browsing etc)
When I go mobile again, unplug AC

My concern:
My battery hardly gets discharged to 0, I am concerned that perhaps not discharging the battery to 0 may wear it out more often (quick charges from 60-80 to 100) but to be honest I dont know. I never concerned myself with how to best take care of the battery.

How do you care for your battery? do you charge to 100 and unplug it from the mini9 while working at desk? and install battery when you are going mobile? or just do the same thing I do?

Mobile for me means just around the house, reading in bed, maybe a trip to starbucks.

I have seen many SSD's die when they battery goes to 0, not sure if its related but I wouldnt let it go down to zero, on my Mini 10 I usually have it plugged in, every now and then maybe every couple of weeks I let it go down to about 40% then plug it back in again, but I dont use mine that much, it sometimes sits in the case for 2-3 weeks at a clip, even now I am on my big HP 17" laptop, the Mini is in the case, but even sitting for 2 to 3 weeks when I do fire it up its still at 100%

I charge my Li-ion batteries when possible and run off wall power when possible. Li-ion batteries only have so many discharge/charge cycles in them, don't waste 'em. But it might be a good idea to run the battery down every so often, if just to calibrate the OS battery life estimates.

I have read it's best to undercharge Li-ion batteries (maybe to 70% instead of 100%), but that'd require the chore of removing the batteries when partially charged and reinserting them before unplugging. And I bought the batteries to be used, not to be neurotically cared for. So, I don't bother.
