Battery discussion

I have a single Optima red top 12v battery in the trunk of my avatar Demon. 408 at 10.5 CR using a mini-starter. Cranks as fast as you would ever need under any conditions I've ever had - hot or cold. 95A single wire alternator with a 4ga charging wire feeding it. First Optima battery I've had - been amazed by it. Always full up and ready to go.
