Bang for buck battery
Optimas are a decent bang for your buck. Not the most high dollar too of the line battery but better than most. Above average quality at a price that is not too far above average for a decent battery. Walmart shipped them via a 3rd party seller which is usually fine but I have been waiting on the third battery for 10 days past the delivery date and the seller has not updated me on what is going on as they said they would a week ago. Pretty sure Walmart will make it right though
Verified Purchase
Expensive compared to other batteries but the warranty and the cold cranking amps are worth every penny. I highly recommend
Verified Purchase
Solid battery
I went with this battery for a battery relocation for my c5 corvette. Everything seems to be fine so far. Fit in my battery box fine. No problems with cranking.
