Few people know that battery lights are more than just a battery light to tell you when your batteries are less than 25%, Part Number Battery Lights tell a lot more. With the proper tool (CDM Reader) or using a credited repair facility who has these capabilities the battery light emits valuable information to tell you what's going on with your cart. 1. Battery Pack Voltage 2. Energy Units Removed Since Last Charge 3. Total Energy Units Used on Batteries (basically mileage on the batteries) 4. How the Last Charging Cycle was Completed (Was it unplugged prematurely, it complete itself, was it interrupted...) Battery lights are not just battery lights. So before you purchase somewhere else, make sure you know what it's supposed to do!!!
