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.
