Batteries High Performance D27F YELLOWTOP® Sealed AGM Battery | Dual Purpose Car, Truck and SUV Battery, 830 CCA, Maintenance Free, Versatile Mounting

I have been reading mixed reviews of Optima batteries since Johnson Controls took ownership, but decided to give it a shot since I could not find a comparable alternative that was proven superior. So far the battery is everything I expected - strong and consistent with a nice reserve capacity. If anything changes I will update this review but so far so good. The only issue was the packaging - actually there literally was NONE the way I found it on my porch. I came home and found the battery lying NEXT the box it was shipped in on it's side, and the box had simply "busted" at both the top and bottom. The UPS guy did not even make an effort to put it back, and I don't blame him as it's not his job. Why the shipper used a paper-thin box with only one strip of tape, I cannot understand. I know for a fact when you order an Optima from the factory it comes in a very thick cardboard box with strong tape. This was the opposite - a box meant for shipping teddy bears not heavy batteries. I would not purchase this battery from Amazon again, simply because this vendor chooses to save a few dollars on economy packaging methods. I would rather pay more and not find my battery lying on the ground, obviously having burst through the bottom before the delivery man was finished setting the box down.

I just replaced my Optima Yellow Top, 6.5 years after it was manufactured. My current battery is close to the end of it's service life, but that may be another year or ? My neighbor will let me know how long the old battery lasts in his spare truck. This is a premium AGM battery that fits my Tundra without modifications. This is a dual purpose battery used for starting and high amp hour use. So you run your Jeep or 4x4 Truck in remote places, need extra juice for lights, winch, or fridge? Or you just never want to have a dead battery in your work truck. Yeah, spend a few extra bucks for the right tool. If you just want the best battery available then you want either Optima or Odyssey AGM batteries.

I bought one of these, here on Amazon, in 2015 and have used it on my tractor for the past 10 years. It finally started to have trouble holding a charge about a year ago, so I added a trickle charger (battery minder) hard wired into the tractor - and that worked until today. Today, I had trouble getting the tractor to crank, and trouble getting the battery to take a charge. So I put it on a battery booster for about 20 minutes. I got back on the tractor and turned the key and BLAM!!!. The battery exploded and blew the top off in many pieces. But I didn't notice any acid and nobody got hurt. The top blew apart, but the sides remained intact. So my advice is to buy this battery and enjoy many years of reliable operation. But after 10 years - pitch it and get another. Don't go through nutrolls trying to get even more years out of it. Take the win.

This battery is pretty nice! I've bought 2 recently. Hopefully they last. The batteries (different brands) they replaced were 10+ and 8+ years old. I'm expecting long life!

This was the best battery I have found for the intended use. It combines a deep cycle with the power to start. Now made in Mexico and has gone downhill. Will not hold a charge even with no load on it. Consider carefully buying online as it is nearly impossible to return or get replaced under warranty. Optima is zero help.

Honestly, how can you go wrong with this battery. Expensive, but worth every penny. Starts my Toyota Tundra like an F/A 18 spinning up it's jet engines!! Also, can mount this dry, non flooded AGM battery in any position. Cannot get any better!!!

It's an Optima, need I say more? Best battery on the market! I've had a number of batteries for my '05 Toyota Sequoia and this is the best. We tow a boat or our travel trailer a lot and use the lights a lot. I have an upgraded alternator however the other AGM and Gel batteries deep cycle and not could keep up and none have performed as well as the Optima YellowTop. This pup fires up my SUV like a rocket and always has the power to run everything. I love it and if you can drop the extra money you will not go wrong! Long term you'll save money as I've go through 3 batteries over the years and this one will out last all three!

These used to be way better and I would swear by them. They would last 10years and multiple full discharges. Lastest one, I'm 4 years in and its completely shot. Was treated well with no full discharges. Basically what you get out of a standard battery for 1/3 the price. I'll look to see if there are other others available now before pulling the trigger in another one of these. It's possible I just got subpar one compared to what I was used to with Optima.
