I have an old Cat 12 grader that has 6 volt starter on the pony motor. Have an Optima in it. Sat for two years and fired right up a couple weeks ago. Yes, spendy, but less so in the long run. On the other hand, had a heavy duty Fleet Farm tractor 6 volt in my '36 sedan that just crapped last week--build date sticker was 2009. And it sits a lot with a tender on it every once in a while. I am going to replace it with an Optima.
