So after finally getting my Prizm going again I went through a pallet
full of old batteries. Mixed in with the 100ah batteries from my shed I
had about 40 Hawker Genesis batteries that I removed from the car 3
years ago and left outside to sit.

These were used batteries that I ran in my Prizm for 3 years then pulled
because 8 of them were bad and I figured "replace the whole pack". On a
lark I tested the 40.

32 of them were able to provide 10.5 volts under a 100a load rising to
about 12.4 volts unloaded. This was after being ignored for 3 years.

I think I'm going to charge and load test these. I might put them in my
S10 truck alongside a string of 42ah Hawkers. However the fact that 7
year old batteries have as much current capacity as new UB12-260s is
something to ponder....

At the same time I need to get rid of the dead ones. I have about 600
pounds of batteries, is there anyone who would pay money for them?

I certainly don't have a lot of experience with lead-acid batteries, but my
impression is that they always have their greatest value as core charges for
people buying new batteries. In my experience, the cost you have to pay if
you don't have an old battery to exchange when buying a new battery is
always WAY more than you can get from a battery by itself.

Do you know anybody about to buy a new traction pack? They might willingly
split the core charges with you to get your batteries and avoid the new core
charges.
