Interstate 6v Golf Cart Batteries Deep Cycle 1yr old, Still in cart

Six deep cycle 6 volt Interstate batteries. Date tabs punched at May 2023. I'm a retired old fart, bought a 36v golf cart to soup up. Previous owner had replaced the batteries last year. I'm replacing the six Interstate batteries with lithiums and selling these. They're still in the cart, take it for a spin. Bring a load tester, or use mine. Current price at Costco for their generics is $105, plus tax, plus $15 core, $753 out the door assuming you don't have cores, so this is half that. * Price is firm, NO trades, cash only * If the ad is up I still have it, please don't ask. I will delete the ad the minute it leaves * Nothing else included, just the batteries These will fit Yamaha EZGO Club Car Columbia EZ GO golf carts or RV camper trailer motorhome $375, cash, price is firm.
