So far, so good!

Great batteries

Purchased 3, 12 batteries to replace my 6, 6 volt batteries for my Duffy pontoon boat. These batteries are great, l saved 270 pounds of weight right off the top. There things are so lite compared to my out deep cycle batteries. My boat goes faster and battery life is unbelievable.My boat volt meter shows full battery even after several hours of use. They are well worth the investment.
