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.
