I replaced a 2 month old other brand battery in my motor home because it didn't have enough power to start my on board generator. The Optima started it immediately and has never failed in the month I have owned it. It was a little pricey, but I hope to get years of good service from it.

The battery in used in a tournament fishing boat. This product is good, however for the degree of use that it is used may be better to go with a d27 or d31. The battery seems to be good but not quiet what I was looking for, I was actually looking for the D27 when this one was bought but nobody close by carried the D27. On the boat this battery does not hold its advertised standby time.

This battery is great! I use it on my pontoon boat. Stereo for hours and motor cranks every time. I keep it on a battery tender year round. That is the key to a battery's life.

Replaced my bargain $100;marine battery with this incredible battery. It was night and day compared to old battery even when it was new. Thia battery spun and fired my Yamaha 130 on less three seconds. Before old would battery would take for ever to fire. A+. I am sold on Thu battery twice the price but worth every penny.

Comments about OPTIMA Batteries Blue Top, Deep Cycle Battery, Group Size 34, 750 CCA:

I have put several Optima batteries in my cars, when the originals started to fail. Now I own a truck and wanted to add a winch, but didn't want to tap off my existing wiring. With the extra set of terminals, I was able to keep the factory wiring and add the winch wiring.
My only complaint is that the install would have been a lot easier if I could have gotten this battery with the terminal positions reversed.

      This battery packs a punch! Dependable starting power even during cold weather. This is the fourth one I have purchased this year to replace all of the lead acid batteries in the boat. The biggest advantage is the substantial weight difference compared to other batteries the have the same reserve and CCA.

          Hi, I'm considering replacing my 2 group 27 lead batteries on my boat with 2 of these in this size. The old batteries are 750 cca but I'm not sure about amp hours.. I don't run much with them but I guess Im wondering if the upgrade in materials would offset the larger size of the lead batteries? It would be great to save space and have equal or better output!

        • Q:

          I am considering using this battery in my Jeep. My reasoning is that I don't want my winch hooked up to power all the time. With this batter I was thinking that I could leave it disconnected until I need it. I was thinking on being able to just hook it up to the stud post with a wing nut and unhook it when I was finished using it. Would this be a good battery to use? My winch usage would most likely be 1-3 times a year.

          How long will this battery hold a charge when not in use in cold temperatures?

          • CUSTOMER CARE

            A:

            Excellent question! I wish I could give you an exact number, but you can never tell with batteries. Heat damages a battery more than the cold does so it really should not be too affected just sitting unused. Since it is an AGM battery, they hold up better in all climates than a regular flooded battery. You will want to keep the battery above 12.4 volts while storing it. If you do not have a battery maintainer, you will want to check the voltage about once a month to ensure it is not below 12.4 volts. Charge the battery if it falls below 12.4 volts. We do carry Part Number 150-40000 which is the Optima battery maintainer. It will monitor the battery state and charge when needed.
