Where I work we just paid a large sum of money to get our electric golf cart fixed. Evidently, golf cart batteries aren’t sealed, and leaving the charger plugged in doesn’t ensure the batteries will work when you need them. Some preliminary research indicates golf carts use special deep cycle batteries. We haven’t used our golf carts in a while, and now we’re using one of them them when we don’t need it in order to make sure they stay charged and in good shape.
I have several questions:
Do these things really need deep cycle batteries? Wouldn’t some large truck batteries, like the lead acid batteries used as house batteries on RVs, work? I know some home made electric cars use regular car batteries wired together. Why couldn’t we put regular sealed car batteries in a golf cart that rarely gets used?
Does anyone make a sealed maintenance-free deep cycle battery? I can’t seem to find them in the right size (big). When I google “sealed deep cycle batteries,” I mostly get the types of batteries that are used for computer back-up power supplies.
Shouldn’t I be able to use a smart battery charger (like the Battery Tender or Battery Tender Jr.) so I can plug in the charger and forget about it? The chargers that came with the golf carts look pretty old, and can’t be left plugged in indefinitely, at least according to what I’ve been told.
What else can you tell me about electric golf cart maintenance that I don’t already know and should know?
