Barry’s DIY project involves an electric golf cart in this video, demonstrating how to replace the batteries on a 2010 Club Car Precedent. There are six batteries on this cart, which can be removed by section (this is shown in the video) or by replacing the whole set at once. Before starting, Barry ensures the tow switch is in the tow position. Then, he removes the battery cables before removing and replacing each battery one at a time. It’s important to orient them exactly the same as the old batteries. The cables are secured to the new batteries. Barry finishes the job by spraying sealer on the terminals, which helps prevent corrosion and battery drainage while also improving electrical flow.
