Old car batteries are at the end of their life because they have low capacity or have shorted cells.

A battery with only 50% capacity is pretty useless for a car but if you get it for cheap, its a great deal for a home battery.

The realities of batteries is that most of the cells will be at 90% capacity while a few will have dropped to 50%. So recycling really can be just plucking out the good cells and breaking down the few old cells.

Those 90% cells will also have a pretty nice degradation curve as most of the loss happens within the first few years of operating.
