Golf carts should not be exposed to the sun. The environment with too high temperature will increase the internal pressure of the battery and force the battery pressure limiting valve to open automatically. The direct consequence is to increase the water loss of the battery. The excessive water loss of the golf cart battery will inevitably lead to the decline of the battery activity, accelerate the softening of the electrode plate, and cause fatal damage such as heating, bulge and deformation of the shell during charging.
