I recently replaced a hybrid battery in my gen II and was wondering how much the old battery would be worth? There is a chemical corrosion on all the bolts. I haven't tested each cell for voltage differences. I also don't have much experience with reconditioning batteries or testing/balancing the pack. I'm thinking if I could get the good cells identified then I could get a little bit of cash back from parts. The battery was from a 2005 model in Australia.
