A golf cart battery can last from several months to seven years, depending on the use and care it gets. Proper maintenance will keep your battery operating longer, even if you use your cart frequently.
Golf cart batteries can be destroyed in less than a year if left sitting in a hot garage without being charged.
Allow the battery charger to complete the process by turning off on its own. Short-charging can make your batteries unbalanced and shorten their lifespan.
Check your battery water level and add distilled water when needed. Don't use tap water, which contains minerals that will reduce battery capacity.
Batteries may gradually lose their charge over several weeks--even without use--which could lead to the batteries freezing. A frozen battery must be replaced.
The batteries should be stored fully charged and disconnected from any circuit that could discharge the battery pack. Clean each battery and remove from the battery case.
