OPTIMA Batteries High Performance 75/25 RedTop Sealed AGM Car, Truck, and SUV Starting Battery, 720 CCA, Dual SAE and GM Terminals, Maintenance Free, Versitile Mounting

Bought this battery as it is SUPPOSE to be a great battery. Long Life 3 year free replacement. Battery is DEAD will not charge at a OPTIMA Retail store "Other than Amazon". they will not back any Warranty as the battery was not purchased from them, and I don't blame them. 1 (888)OPTIMA Customer No Service sucks, Their answer is " if you can get it to charge, return to the main menu, buy a new battery" are you freaking kidding me! AMAZIN needs to do something, like not allow them to sell a product they refuse to stand behind!

Why did you pick this product vs others?: Very good product love that I could pay it in payment because it’s a great battery but high price but worth the money in the long run

It's a great battery It's started my truck every single day since I put it in

From day 1 it seemed to just be OK. It worked for a while , but then I had to start to charge it. Then it required a battery maintainer, I'm not sure this battery was as good as it should have been for an optima. I had one in the jeep years ago , and it worked for a long time, But not this one

Great battery so far. But, time will tell how long it keeps doing what it does best for my car.

I have purchased seven Optima batteries elsewhere and never had a problem, then I purchased the eight one through Amazon. It failed after eighteen in months. I contacted Amazon they would not help and said to contact Optima, I contacted Optima and was told that they sell the batteries to Amazon and that Amazon is responsible for the warranty. Neither company will help. I wish I would have read the other poor reviews and never waisted the money I spent with Amazon for the battery. I consider myself a very good Amazon customer and have been satisficed for the most part until now. WHO IS RESPONSIBLE FOR THE WARRANTY ??? WHAT A WAIST OF MONEY!!!!!!!!

Darned oddest battery ever. Had it 3 years, it sat a lot, I cranked on it to ocassionally spin over and then start an engine in a Chevy Luv... like no resistance, right? It was also used to test aftermarket GM wiring kit circuits as they went... Even with the alternator not working... it would bounce back with ocassional charging. It proved to be one tough battery. Then a couple months ago I got the alternator sorted out, and got 14 volts... and was a happy camper... the engine ran strong and didn't die from running down the battery anymore. (missed exciter wire cuz Hitachi Delco instructions didn't indicate need for one but the wiring kit did) That was until two days ago with one more circuit to hook up to be street legal... The weather had turned last month but it rarely got below freezing and the Luv is in an attached but unheated garage. Nontheless the battery went completely dead... like to no nothing, zero, ziltch, no meter, no test light dead... bummer. So out came the charger. After charging overnight It would barely light the test light and showed 4 volts. So I kept on it until the green light lit on the charger, and proceeded to test it this afternoon. No change. How frustrating. At that stage I figure I can't ruin it, so I left it on the charger for a couple more hours and then went back out to check on it... Hmmm... the green light was out and the yellow ones were back on.. meaning it's charging again. So for curiosity I unhooked the charger and tested the battery... 11.70 volts. Hey hey.. From there I tested that last circuit (wiper washer motor)... and got a buzz... that's better, even the headlights worked... maybe all is not lost. From what I'm getting to understand through trial and error, and many reviews; they're weird. In charging they must hit a level where the charger is forced to push through some kind of resistance before it really takes hold. The battery has a diconnect to prevent drawdowns, and the charger is the proper kind. I am a little taken aback by how quickly temps between 28 and 45 degrees killed it. I have a grody 10 year old battery from Les Schwab I use on a winch... and it showed 13 volts today... it hasn't been on a charger since spring... I'd run it in the Luv, but won't fit. Even the cheesy WalMart special in our lawn tractor holds up better in the cold. Weird.

Works great, no core charge, my c5 starts everytime now!
