6 Essential Tips For Storing Your Electric Golf Cart For 6 Months
Storing an electric golf cart for six months comes down to the battery type and the resting state. Lead-acid packs tolerate idle time best when kept partially charged, while lithium packs require a specific resting voltage. The first label to check is the storage voltage in the manual, then set the charger to match that setting.
Storage guidelines for six months: Charge each battery pack to the level recommended by the manufacturer, typically around 60 percent for lead-acid and according to Li-ion specs. Disconnect loads, remove from the charger, store in a cool dry place at 50 to 80 degrees Fahrenheit, and check voltage monthly.
