iBook 14" battery innards

what the actual cells used in a 14' iBook battery were? If they are something I can get from Maplin/RS

I think Adrian Tuddenham has looked inside iBook batteries, in the past, and revived them. I remember looking inside a dead one and the actual cells are fairly 'normal' looking NiMH ones. AA sized at a guess. Plus a number of resistors and/or diodes. At that point I gave up but I'm sure that with a bit more determination it might have been fixable.

Perhaps I'll try and find an appropriate screwdriver and give it a go. Is there anything in there that will give me a shock, I wonder?

How expensive they are if you have to buy a new one?

Oh, I already got one from ebay for GBP20 - nearly a year old, and only at 78% capacity, but cheaper than GBP88 for a new one.

=A320!? Last time I looked they were about =A350 - that was for a 12" though....I'll have to have a furtle.

Lots are buy it now for =A345 with about =A39 postage, occasionally people put them up for real auctions and you can be lucky - if you don't mind a slightly older battery. 4 hour life is better than the couple of minutes I was getting with the old one!

Only the complication of the wiring and the diodes... No, nothing at all. After all, the whole thing is very low voltage.
