Nine (9) new batteries and counting just this year.

As soon as the Speedster is ready to go it will be 10 - or more, who knows.
I just hope the Volt's battery doesn't follow in the golf cart, tractor, 911, and Tundra's footsteps.
The Tundra is especially hard on batteries, averaging only about 2 1/2 years before they quit.
This is getting spendy!!
