Fitment
For golf carts that run 6V lead-acid batteries: six 6V batteries make a 36V cart, and eight make a 48V cart. Order one battery for each position and replace the whole set at once. Check that the group size (GC2) and terminal type match your current batteries and cables, or send us a photo of a battery label and we’ll confirm.
Care
Interstate recommends charging after every use and not letting the battery sit discharged. Top off the cells with distilled water only, after charging. Clean the terminals with a baking soda and water solution and keep connections tight. In storage, keep the battery fully charged, and don’t let a lead-acid battery drop below 50% charge.
Warranty
12-month free-replacement warranty from Interstate. For full warranty terms, see interstatebatteries.com/warranty.

Core charge
Interstate applies a core charge when an old battery isn’t exchanged. Our core charge and how to return your old batteries: Each flooded or AGM lead-acid battery adds an $18 core charge at checkout. A set adds $18 for every battery in the set. Lithium batteries, chargers, and parts do not. The core charge is refunded when we receive the old lead-acid battery.
