Hi All,
A friend has a TiBook whose battery was allowed to run down, and now won't charge. I understand that before this particular problem reared its head, that the battery was holding enough charge for at least 3/4 hour of work (max time it was recently away from AC power, don't know what the real max was).
Any suggestions as to how to determine if it can be recharged, or how to determine if it's really dead? (strikes me as strange that it'd completely die like that, rather than just holding less and less charge until it held no more).
Thanks in advance for any help,
Chas

Sometimes oyu can drian a battery past the point where it can recharge, that is why when your cell phone battery dies you really don't want to keep trying to turn it on to get that one last 30 sec call out.
I am no chemist but I believe this window of no return grows as the battery ages. The same crystallization that cause the battery to hold less charge is also the route cause of the problem of batteries not being able to recharge at all.
Suck it up and get a new battery, it is relatively cheap and newer batteries hold more charge then old ones did; your friend will final get the 5 hours of battery life apple promised in the first place.
My pismo is on it's 4th battery and it now get fantastic battery life, I actually like it more than my ibook for traveling because even though it is slow, I can surf the web write e-mail the airport for as long as my flight is delayed.

thanks for that info tinkered. I wonder what Tibook batteries go for in the UK these days? Guess we'll find out! (hey, he was only keeping it for his kids, and they've already got a Mini :-)
Cheers!

It's dead, Jim. These batteries have three or four individual cells in them. One of the cells was likely dying before, that's why you would only get less than an hour on battery. Now that it's dead, the entire battery is dead.
That's how a battery can just "die", there's a threshold voltage which the battery as a unit has to drive in order to get the laptop to power up. If one cell dies, the battery can't get to that voltage anymore.

A lot of people like to get brand name batteries, but the generic batteries off of eBay usually work just fine. And their is always a chance that the official batteries are bought from the same company anyway.
