The battery is great. Ordering online was the pits! Online order said I could pick this up at a local store in a couple of hours. Ordered and went to the store that evening (30 miles). They didn't have any order. They checked and asked me for a order number. I gave it to them and they couldn't find it. The store manager was nice enough to sell me one outright, honoring the online order price. The next morning I received an email saying I could pick up my battery now. I canceled the order as I already picked it up. This glitch was troublesome and could have been prevented if it weren't for the nice store manager.

Optima battery fits well and performs even better

Comments about OPTIMA Batteries Blue Top, Deep Cycle Battery, Group Size 31, 900 CCA:

Bought to replace two 6V batteries in my van camper. Also found an Optima battery tray that I mounted in my slide out compartment and then secured the battery to it. Battery fits and looks good and no more worries about fluid spills. It should be more than adequate for several days of dry camping.

Comments about OPTIMA Batteries Blue Top, Deep Cycle Battery, Group Size 31, 900 CCA:

As a suggestion, measurements should be given on all batteries, in this instance I had the room for a larger battery. This Marine Battery was chosen for the increased "reserve" or deep cycle power, to start and operate an older auto with s High Compresion engine. Not everyone, would able to easily, remove the battery tray, hammer, Dolly and flatten the ends, in order adapt s larger length on the lower area. I also had modified the inner fender reinforcement, years ago, preped, primed an painted tho to blend in color.

            Can I use this blue top battery as a dual purpose battery? Can I use it both on starting engine and at the same time use it on my trolling motor ?
            Asked on 9/27/2015 by Butch from Pensacola, Florida

            1 answer

            • CUSTOMER CARE

              A:

              Great question Butch, I will be happy to help! Deep-cycle batteries can be used for engine starting but there are specific batteries designed for this application. A deep-cycle battery has the ability to be deeply discharged and charged many times during its service life. It is designed specifically for powering electrical equipment for long periods of time. For applications where both engine starting and light deep cycling are required, a dual-purpose battery is often used. This type of battery is neither a starting nor a deep-cycle battery but rather a compromise between the two so it performs both functions adequately. The Optima duel-purpose part number is # D31T-1125.
