If you want to get daring.
Buy a handheld multimeter to check battery voltage periodically.

Take two measurements.
First, with the engine off, system on - read the voltage ( this is nominal battery voltage)
Second, with cart running - read the voltage.
Engine on voltage should be on average 1.5 to 2 volts higher than engine off voltage.

If the voltages are not different by that amount, you need new Alternator (generator)
