Most lithium chemistry allows for DOD to be 80% and still gets 1500-2000 cycles. While Lithium is twice the price, you get 3 times the life if are traveling 2 hours between charging. Plus Lithium is half the weight of lead, never needs water and absorbs recharge with less loss. Generally speaking, Friends don't let friends drive on acid.

Both EZGO and STAR say they are batteries get about 4000 cycles. To put it into a proper perspective you have to also understand how many miles you get per cycle. I get about 70 miles on a full cycle charge. That equates to 280,000 miles before the battery needs to be replaced. Considering the average golf cart is 20 miles an hour and topped out at 24 miles an hour… To go 70 miles it would take me 3 to 3 1/2 hours every single day of riding in my golf cart. If I was actually able to do that it would take me almost 11 years to accomplish. I'm pretty sure there will be other parts wearing out on my golf cart...not to mention my butt before that actually happens
