Charger

The charger is generally a smallish black box,  supplied with your trolley to charge up the battery.  The charger plugs into the mains at one end with the other attaching to the battery terminals.

Most have a red light to show the battery is charging  at full voltage output (bulk charge) with a green  light to show it’s dropped to a low voltage output (float charge) and the battery is ready for use. Some chargers may also have a yellow light to indicate nearly charged.

The most common fault with a charger is when the voltage output malfunctions and causes the battery to prematurely deteriorate. This is not easy to identify as the lights on the charger normally still function.

The answer is to have your charger periodically tested (Golf Trolley Garage have the neccessary equipment), also to purchase a new charger if yours is over 4 years old.
