Recently I bought a G3 iBook from a car boot sale for £5 - I didn't honestly expect it to work but was hoping to salvage a hard drive and maybe a RAM stick. However getting it home I was amazed to find it booted ok and it turned out to be the 800Mhz model with max RAM and a CD/RW albeit with a completely dead battery. From what I could gather the iBook had last been used in 2009 - so no surprise with the failed battery. I decided to give Panther a whirl on it and after installing realised the battery wasn't seated correctly. After being placed correctly the battery was now showing a dismal faint red line in the battery indicator and one flashing green light on the battery. I reset the PRAM and tinkered away with Panther for about 4 hours - after which the battery still had only one green light. I decided Panther wasn't for me and then did a fresh install of Tiger…imagine my surprise when the battery was suddenly showing 4 green lights and 100% in the indicator! After setting up Tiger with updates etc I tried the iBook on battery only and got just over 3 hours out of it! I suppose the point I'm making is don't judge the condition of an old battery too quickly - give it time to see if the dormant chemistry can be kick started.
