If it is a lithium ion battery, than that is not the case. If it is NiCad, then that is true.

Apple used to recomend draining the battery completely, then recharging the battery when it started no longer holding a charge for as long as it should. Unfortunately, this process actually had a nasty habbit of kiling the battery in question permanently. I believe apple has addressed this issue in their newer batteries, but I was one of the unfortunate victims of this policy. And, although apple replaced my battery for me, they also informed me at that time, that this is no longer their recomendation of how to handle the battery. However, in general, letting a battery run down to almost empty before recharging it does indeed make the battery last longer, over the whole life of the battery. Multiple micro discharges and recharges tend to reduce the overall battery uptime, due to something called memory which develops in the materials the battery are made from, after a a while, the battery simply won't discharge below a certain point if it's not been allowed to reach that point for several charge/discharge cycles. Of course, all this information is only current as of 1.5-2 years ago when I had my battery issues, so it's always possible battery technology has changed, though I doubt it's changed significantly. It's always been my experience every since I was old enough to observe such things, that batteries overall last longer if allowed to mostly discharge before being plugged in to recharge. I've seen nothing in my everyday dealings with all kinds of rechargable equipment to disillusion me of this just yet, but as always, your mileage may vary. <--- Mac Access At Mac Access Dot Net ---> To reply to this post, please address your message to [email protected] You can find an archive of all messages posted to the Mac-Access forum at either the list's own dedicated web archive: <http://mail.tft-bbs.co.uk/pipermail/mac-access/index.html> or at the public Mail Archive: <http://www.mail-archive.com/[email protected]/>.
