Re-use is bigger and more efficient than recycling so far, though there are several recycling businesses in North America.
A lot of used car batteries are being used in stationary applications.
When a battery gets too inefficient for a car it is still a good battery, it just not efficient enough for the demands of a car (weighs too much for the amount of energy it can store). It works fine if it's sitting still, storing energy for a stationary application. I think a car battery is declared "dead" when it's storage capacity drops to something like 80% of its new capacity.
