OPTIMA Batteries High Performance 34 RedTop Sealed AGM Car, Truck, and SUV Starting Battery, 800 CCA, SAE Terminal, Maintenance Free, Versitile Mounting

My last Optima Red Top lasted 8 years in my 2001 V8 Grand Cherokee. It recently developed a bulge on top and did not hold much charge/got weak but after 8 years I cannot fault the battery it did a great job and never left me stranded and always had reserve power to run the stereo etc with the engine off from time to time. So I checked Amazon and found the same battery to replace my old one. Hope for another 8 years. When I sell the Jeep I will be keeping my Optima. I also have a Optima Blue Top deep cycle in my boat and it was bought in 2007 and still takes a full charge and works great. Optima is the best battery for the best cost hands down. People who are having issues with them are not using the correct charger or charging at too fast a rate. Never charge a Optima over 10 amps slower is better 6 amps or less is preferred and only use a charger designed for AGM batteries. Never discharge a Optima all the way down and you won't have issues.

Put this in Subaru Forester. Fit fine with slight plastic under pan adjustment due to longer length. I did buy an oversize battery so don't consider that a down check. Came almost fully charged which I topped off with a Battery Tender charger. Has worked flawlessly for a couple of months. I know some people seem to have a problem with these, but mine is fine. Now if it lasts for many years, I will be pleased. Car starts quickly every time. Compared to local auto stores this price was 2/3. Make sure you are aware of the Amazon on line warranty support. You cannot take this to a local auto store if there is a problem.

These Batteries are Fantastic, My truck starts super fast. I switched from Super Start Batteries in my 07 F250 and won't buy anything but Optimas from now on. It was a tight fit on the Drivers side since I chose to keep the plastic cover the battery posts were what made the cover fit snug. Other than that the adaptors that came with them worked perfect. Update- I have owned these batteries for about 3 months now and have put roughly 4000 miles on them with close to 250 starts off of them. They are working great still even though my short commutes daily hardly seem like enough time to recharge after the energy it takes to Crank the ole 6.0 power stroke. These batteries do charge a lot faster than the old batteries I had from the local parts store. I will try to keep updating this review if after 12 months or so anything changes. I am incredibly happy that I spent the extra money and bought these over the competitor.

EDIT: DO NOT BUY THIS!! These used to be the best on the market, but these must be old stock! Mine lasted about 3 months and only one drive in my truck! I had a lot going on at this time and couldn't drive my truck more often, nor take time to return the battery, but I will never buy here again! We drove it ONE NIGHT and then it wouldn't even turn over the starter on the truck.. tested it and it was toast!! I will now have to find another company and hope they are as good as Optima USED TO BE.. This is a great battery as everyone knows by now. This only my 2nd one I have ever bought, because they have long lifespans. I put this one in my 2003 Ram 1500, that has the Off Road Package. Though it was a little too small for the battery tray in my truck, they provide adapters to make this battery fit in many vehicles. My truck had the upgraded battery when I ordered it from Dodge new, which was up from 500 amps to 700 amp. This battery though, even blows those numbers out of the water with 800 & 1000 respectively! I installed this along with a new Gladiator alternator and a new Gatorback serpentine belt and it all runs beautifully! I can't say enough about these batteries and have converted my whole family of gearheads over to the Optima line of batteries. Those people saying that these are overhyped, obviously either got that one in a thousand dud, or they think that batteries are indestructible and abused the heck out of them. Remember, there isn't a battery on earth that will not eventually die.. It was shipped to me in double box packaging, which very thick foam pieces holding it in place and arrived in perfect condition. You just can not beat Amazons price and ease of shopability with things like these. You go to Autozone and pay 185 for a junk battery that will maybe last one year, or you can buy this and just wait 2 or 3 days to have it.

Perfect high performance battery.

I was advised to get this brand and they were right. The winters up here are harsh and the cold had my battery feeling the pain of a weak start. Once this beastie was installed, easy job, the vehicle leaps to each morning in a single crank. As to installation. Use the instructions. They outline which of the plethora of adapter plates are required for the particular vehicle. Once done correctly, the battery is housed tight and secure. This technology is safer and more powerful. Batteries do not last for eternity and at roughly 60 bucks a year for this in its expected lifetime is security well worth the cost.

Installed the RedTop in my weekend project car, an older model that doesn't see daily use. Initial impressions? Solid. The cold starts have been noticeably quicker, even after sitting idle for weeks. The build quality seems up to par with the premium you pay, and installation was straightforward with the included instructions and adapters. Haven't had the chance to put it through extreme conditions yet, but so far, it's living up to expectations. If it holds up over the next few years as my last battery did, it'll be worth the investment. Only time will tell, but for now, it's performing as advertised.

Battery lasted 6 months. Won't hold charge. Defective, charged with special AGM charger, shows Defective. 3 year warranty doesn't apply because Amazon is not an authorized dealer.

over priced not worth money
