## Questions & Answers

**Q: What does the "Amp-Hour" rating of this battery translate to in deep-cycle mode?**
A: For trolling motor use you would divide the current draw of the motor into the number of amp hours to find out how long the battery would perform at that level.

**Q: Does this come with any 5/16 wing nuts for the studs or something's similar?**
A: Yes it does.  I'd have to go check, but I think it has a 3/8" stud for the positive and 5/16" for the negative, along with standard battery posts.

**Q: Can this be mounted on its side?**
A: Yes no acid

**Q: I hear these batteries are damaged if they go below 80% charge, is there a guarantee I will receive a fully charged battery?**
A: My boat mechanic is a optima dealer he told me a standard battery charger will never get the battery to full charge you need to get a optima charger. I had a battery that wouldn’t charge. I used the optima charger and it finally got a full charge.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Top Quality
*by J***R on August 15, 2007*

Optima batteries are one of the best on the market. I am very impressed by their longevity and high power delivery. I have had a yellow top Optima in my 4wd truck for 9 years now and it is as strong as the day I installed it. Other great features of Optima batteries are the facts that you never have to add water, they can be mounted in most any position and the terminals never corrode.This purchase was a second blue top D31M. I use two of these batteries in parallel to power a 2000 watt inverter. I tested it by placing a 1500 watt load on the inverter which drew 137.5 amps from the two batteries in parallel. They were able to sustain this load for 27 minutes. That is like cranking a 6 cylinder engine for half an hour. I previously used marine deep-cycle flooded-cell batteries for my inverter but they would only last about two years and I constantly had to check and add water as well as clean corrosion from the terminals. The bottom line is even though you pay more initially to buy an Optima battery the long life and power delivery quality actually make it cheaper than other batteries when you divide the cost by the number of years of service.

### ⭐⭐⭐⭐⭐ The batteries that won't die when you need them
*by B***G on December 22, 2015*

I originally purchased these batteries 5 years ago for my old 5th wheel. I stored the rv at a campground in Arizona for 6 months and forgot and left the ceiling fan on. Of course the batteries eventually ran out of juice and were in a constant discharge for the whole time. When I returned, I put the rv on shore power and charged the batteries. I kept them in use for 2 more years for dry camping and solar charging, then transferred them to my new truck camper, where to this day, they are storing power from my solar panels and are still working as they should. They have been in service for a total of 5+ years so far. I have never been able to get regular plate batteries to last more than 3 years, definitely worth the difference in price if you need reliable power storage.

### ⭐ 2yr Battery UGWU$4
*by A***S on October 18, 2024*

Purchased 09/16/2022, NEW, to replace an old Dual Marine NON-AGM Battery that was 6yrs old. Did hours of reading and research and reviews before we made the decision to purchase this Blue Top AGM Battery from Optima. We weren't able to get the boat in the water in 2023 due to my FNL having medical issues, so we kept it on a battery tender and then April of 2024 we put in the boat, 2012 Hurricane SunSport 202 w/Evinrude E-Tec 200HP OB and it ran great all spring and Summer. We pull the boat out approximately 4 weeks ago and noticed battery was week and it says it has a dead cell and won't charge completely. Will not purchase another battery from Optima and will go back to a traditional marine battery with much greater life expectancy. Spending more money for what would seem to be the "best" AGM battery for our application turned out to not be the case. Thanks, Optima, for a subpar performing product.SincerelyUGWU$4
