Powakaddy FW3 - Not Perfect

FW3 Powakaddy Golf Cart - Not Perfect Condition Includes cart, battery and charger... Cart is perfect - wheels, frame, folds and works fine Issue - battery stops every so often - I can't tell if it's the battery or the switch or what May suit someone that can fix it? Works fine most of the time but the battery sometimes stops working... can do 18 holes no problem but you sometimes have to take the battery out and put it back in again for it to work. Might just need a new battery? Or to get it looked at and rewired? No idea... Price based on perfect cart and not so perfect battery, thanks! Contact me if you want more info please
