I bought this for my pop-up camper about three years ago and this Optima started deteriorating about a year ago. Now it is completely dead and will not take a charge. I took it to a local Batteries Plus store and they tested it and tried charging but no luck. I followed Optima's instructions on how to revive a dead battery but still no dice. I was expecting the Optima to last at least 6 years or more.

I kept this battery charged during idle times and only occasionally allowed it to go below 11.8V. My other cheaper, off-brand 12V batteries lasted lot longer and perform better than this over-priced Optima.

Lesson learned...I'll just buy cheaper flooded lead-acid or off-brand sealed lead acid batteries from local stores.
