The most complained about component on an Electric Golf buggy. Everyone has there theories on which are the best way to charge them. Some people will tell that they let them run flat after a few games and give them a full charge believing that this helps.
Maybe sure but the way our batteries are designed and the chargers that we use, it’s not quiet the case. All battery manufacturers and suppliers will tell you that you should have your battery on charge with a smart charger at all times when the battery is not in use. The way a deep cycle battery works is that they are designed to work without being charged for a period of time, then they need to be rejuvenated by being charged right up until next use. Not like a car battery, as you are driving the alternator is rejuvenating the battery at all times.
The most important thing that I have learnt about deep cycle electric golf buggy batteries, is that when you strike a problem on the course; hopping on the 17th hole or similar, most people would take the battery to the auto electrician or the buggy manufacturer and they will perform a battery load test.
Problem, most cases they will tell you that the battery is okay, but this does not simulate it driving on a golf course. This procedure works with car batteries as they are testing the cranking amps which would start the motor of your car. Golf buggies don’t rely on cranking amps so this is not a true test.
They accurate way to test the Deep Cycle battery is to fully charge the battery then set them up on a system that drains the battery over a period of time drawing the amps that it would on the golf course. Times logged of procedure started and the rate that it loses its charge and the final outcome is worked out mathematically with the specifications of the battery. Sounds boring but it’s the only way to truly test the battery.
