We know they are expensive. We know they can be dangerous, although for the most part, as long as they aren’t abused, over-charged or spring a leak, they are safe and reliable – given they have been around since the mid-19 century and we’ve learned how to build them quite well. Frankly, unless we drop one on our foot, they are very safe and very dependable until they get old and run out of juice.
That said, lithium batteries are sealed, maintenance-free, quick to recharge, long-lasting and very light. Obviously, these reasons lend themselves very well to running golf carts, where less weight means more speed and where long lifespans make them cost-effective. It doesn’t hurt, either, that they are quick to recharge and require virtually no other maintenance.
