I work on electric forklifts and other small electric powered equipment and deal with deep cycle batteries daily. In a race car if you can handle the weight run a AGM 12 volt deep cycle and forget about them for 5 years or more. I have had good luck with deka brand group 24 AGM batteries. Weigh 45# each. I had a pair of them in the car for over 5 years and then moved them to the trailer and they are still powering the winch, lights etc. Plus you can leave them for months and still hold a decent charge.
Years ago had good luck with optima brand but at some time there manufacturing was moved out of the country. After that they did not last as long, not sure where they are made now or if that problem has been corrected.
