This is the worst company in the battery market. I am a retired elderly gent living on Social Security. I purchased a set of batteries for my wheelchair in 12/18/20. The batteries were recommend by Chrome Battery for the application and model of my wheelchair. Within 6 months the batteries failed to hold a charge and left me without a wheelchair. After talking with the company they agreed to warranty the batteries if I would pay the freight expense to ship them to me. Now just 6 months later the second set of batteries have failed. No warranty, no wheelchair. Now have to come up with the money to by a new set of batteries. This company makes the worst products and you would be wise not to buy their products.
