It's a car battery in my 2015. Those optima batteries need to be kept fully charged. If they drop below 9-10 amps you have to use two car batteries to bring it back up. Way different than a standard battery.
Please elaborate. I have the Yellow Top Optima in mine & when we were at the beach I ran it down (SS wouldn't start "click, click, click") we pushed started it (pop'd the clutch) & haven't had any issues. I assume you mean when they get old and drop? Or is 9-10 amps low not a "normal" thing?
