Necessity of Previous Hints?
Authored by: Enkerli on Apr 02, '03 12:48:52PM

There's been several posts on battery life lately, but what's the bottom line? Is draining-and-recharging really necessary? With current [i,Power]Books? What should we expect from, say, a one-year-old battery?
(I rarely use my iBook on battery for extended periods of work)

No one really knows. But Apple has put out a knowledgebase article (http://docs.info.apple.com/article.html?artnum=86284) that suggests you should try it.

According to BatteryUniversity, you should avoid a full discharge cycle with Li-ion (as found in newer Powerbooks) as overall battery capacity is reduced.

The whole site makes interesting reading and there's a summary table at http://www.batteryuniversity.com/partone-21.htm.

Very true. This is not something that should be done regularly. But if it helps to do it once in a blue moon you are going to gain more than lose.

Batt.Bash
Authored by: tgermer on Apr 02, '03 11:56:55PM

I tried this last night and now when I running the batt.bash script that was recently posted here it says my capacity is 4231. Where before I did the battery drain it was 4285. Weird.
