Performance08.12.2016 ByMark Powell This has been proven top quality battery in all the applications that our company WUMA ENTERPRISES USA calls for. We use these batteries in a few demanding situations where there is no room for failure to take place. If the battery doesn't perform correctly all the time then that can be extremely harmful to the situations we put them through. That's why this particular battery we use consistently. It's built the right way.
Optima Battery D3117.05.2016 ByBruce Collister Definitely the best batteries I've ever used,MY first pair lasted 11 years, never had a problem even though I would anchor for sometimes 8 hours with livewell,GPS,fish finder,lights,and radio on and the boat would always start. I would bring them indoors in winter and put on trickle charge
great optima batteries02.05.2016 ByPeter Black Great price on Optima Batteries. I got 2 in a week and a half. I wasn't sure of when they would arrive, due to not getting an update on the shipping. But, I got 'em in a reasonable time and they're great batteries! Thanks!
Optima D31M03.12.2012 ByDuane Williamson It is too soon to determine the longevity of these batteries, but I have installed 6 of them in my GEM 4 passenger NEV. So far I have determined that my maximum speed is sustained at a much lower voltage than with the previous batteries. These units appear to loose voltage at about the same rate as the previous batteries, but the cart runs 2 to 3 miles faster when the voltage is reduced. Thus far, I am pleased with the product.
