I don’t believe that Interstate has any true Deep Cycle batteries. They may say Marine/RV Deep Cycle, but they list CCA and CA (cold cranking Amps and cranking amps) which is not a real Deep Cycle. You should never get below 50% state of charge (some say no less than 80%). Anything below that drastically shortens the life of the battery and may not ever take a full charge again.
