OPTIMA Batteries High Performance 35 RedTop Sealed AGM Car, Truck and SUV Starting Battery, 720 CCA, SAE Terminal, Maintenance Free, Versitile Mounting

Got this for a 2005 Mustang GT. Fit perfectly. It has WAY higher CA and CCA ratings than the Duralast Gold it replaced. I've ALWAYS went with Optima because they last forever. Yes, they are expensive, but they are TOUGH, they don't die on you if you happen to let them drain dead overnight by leaving the radio and lights on for 20 hours or whatever like many batteries do. I'll update if any issues come to plague us, but if you don't see me come back, just know the battery is still doing perfect, even if it's 8 years from now. I may update every 3-4 years and say how it's doing, but I have faith 4 years will be trouble free with an Optima Red Top. I'm just saying, it's worth paying the extra hundred for one of these than saving that hundred and needing to buy another car battery 8 months to 2 years MAX later. These last forever AND they blow the competition away with the cold cranking amp ratings (the important rating). I've used these since 2005 or 2006. I even keep a spare that I've had for 6 years that I keep to bring with jumper cables if I ever need to jump someone off since it's so much easier. I think it may be 8 years old now, actually, lol. Long story short, this is one of the most important components of your vehicle. THIS decides whether you crank and leave or get stuck where you parked. This decides if you run it dead, will it still be good (yes) or will you kill a cell with some other cheaper brand (you will). Spend the money for one of these and then you can forget about worrying about your car battery for YEARS to come.

I just replaced the Optima Battery I installed Sept. 26, 2016 with the same one, on Nov. 13, 2020. This Battery probably would have lasted longer but my Alternator failed and I drove the car home 15 miles on just the Battery, 3 weeks after I replaced the alternator. I went to start the car yesterday (11/12/2020) and when I turned the key the usual dash lights and gauge lights did not illuminate and there wasn't even the usual click from the starter it was also 17 degrees outside. I checked the Battery with my Multi-tester and it registered 3.6 volts. I used to get my Car Batteries from Walmart, El-Cheapos and get maybe 2 - 2 1/2 years not much more. I never had a Car Battery last over 4 years. The Battery cost more than I could get for the 1999 Nissan Sentra 1.6 liter, with 220,000 miles on it, that it's in, but I work the graveyard shift and the last thing you need is Car trouble and what's even worse is during Utah winters, and as long as it gets 25 City / 45 High-way mpg. I'll keep driving it . I also replaced the Pressed Plastic Tank Radiator with a Griffin Aluminum one it's been in there 10 years. I will continue to buy and install Optima Batteries in all my vehicles. I also have one in my Subaru Outback, and that Optima Battery has only 2 years 7 months use on it. Thank you Optima.

I bought this because I wanted a super powerful battery that won’t prematurely die in Florida heat. It meets or exceeds my car’s battery specs and starts INSTANTLY. Even the a/c seems to be running a little more briskly! I’m very happy so far

I installed this thing after my so called 80 mo battery died. Fired up my Titan with MagnaFlow Exhaust & 3 1/2" - 4"" inch Tru-Flo Air Intake and the damn thing Roared like a Lion! Hmmm, maybe I'll post a video so you can hear it.... OK ok, so the battery had nothing to do with the sound, but it made the truck start really quickly - I mean it turned the thing over like it was mad at it or something. LOL - Well if you need a good starting battery, then get it... I've had it installed for about two weeks now, and I've completely drained it twice with interior lights and radio while working outside at night. It's still kickin' - I know it warns against deep cycling the battery, but I didn't do it on purpose. Anyway - so far - so good! I like the battery. I'm not gonna propose to it yet, but I do really like it. Hope this helps somebody. UPDATE: Feb 22, 2013 ------- OK - it doesn't roar in the winter - it clicks! it hasn't dropped below 30 degrees here, and all I get are clicks in the morning... I've disconnected my stereo turn-on lead, so the second battery and amps are not engaged by the PAC-500 solenoid, and not pulling from the alternator while driving, or coincidentally pulling the main battery (Optima) down during start. I'm using a jump-starter to start my truck when I hear the clickety-click. I will see if this clicking crap keeps up, and when I'm bored as hell, like I am right now, I will come back and update this posting! UPDATE: MAR 18, 2013 ------- Seems to be fine. 1) My negative cable end was tightened to the max, and was still loose on batt terminal, so I squeezed it together with pliers, and tapped it back down onto the battery terminal. 2) I had the batt tested before step 1 above and it was at 33%. 3) I drove truck to charge batt, but had to use my jump starter a couple more times in morning & once after work 4) I disconnected my stereo, drove it on the hwy, etc to charge up the battery 5) Has been starting just fine, even on coldest mornings here which have been down to 31F. FINAL UPDATE: JUNE 16, 2013 ------------------------- I DITCHED this battery last week for a DIFFERENT BRAND, and now my truck starts every morning - no clicks!!! Fortunately I had a jump box that started my truck every time this thing decided it wanted to take a nap. I replaced it with an O'reilly Autoparts Extreme battery. The last Extreme I had lasted 3 1/2 yrs in the Georgia heat, and with the factory Rockford Fosgate entertainment and Nav package. The Extreme has a 5 yr warranty that I did not use the last time, cause I could not remember where I bought the damn thing from. - LOL - yeah I know! Anyway, seems only a small percentage of these Optima batteries actually work. Shame, because they built such a great reputation for excellent batteries, now it's ruined. - These new ones are pure crap! 180 Degree turn on my initial review - This is a piece of Shieza!!! No Warranty - No Return - No Working = No Buy!!!

Great so far. New battery for minivan. Works flawlessly

Meilleur Batterie AGM sur le marché Évidemment je l’ai fait charger à 100% avec un chargeur intelligent car la batterie ne l’était pas sûrement à cause qu’elle était stocké dans l’entrepôt

Fits on my Nissan Frontier 2016 Pro 4 x . Shorter than the original height though. You can make a spacer underneath to match. Great product!

Best battery for Canadian winters.

Never buy in Canada. Warranty is not honoured. A dead cell and no resort but chasing amazon despite warranty.

I bought this battery as a replacement for my old lead-acid battery. I needed AGM cause I do lapping events with my car and the lead-acid batteries are unsafe in case of an accident. Especially in my case, I've changed the location of my battery, it is now in the center of the passenger compartment, right on the floor. The battery was a bit low when I received it, but it's probably just for sitting on the shelves for a while. Gave it a good charge at low amps for a couple of days and it works just fine now.
