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

I have a 2016 Toyota Tundra and the last battery I purchased was an emergency change out on the road and paid about the same. This battery has great starting amps and is half the size and weight of my last battery no issues charging, fully charged was a concern by other post.

I have a 2003 F250 with the 7.3 Powerstroke diesel engine, which requires 2 batteries. The specific size batteries for this pickup are not cheap. So for a few more bucks I decided to upgrade to Optimas. I was worried they would be difficult if not impossible to secure the same base clamps, Optima to my pleasant surprise was one step ahead. They come with snap-on adapters for several different base clamps, and a platform to raise the height of the battery for certain applications. Both batteries are solidly clamped in place with the factory provided fasteners, it took less than 30 minutes to remove the old batteries and install the new red tops. I am looking forward to years of worry-free dependable starts!

I've had about a dozen or so Optimas over the past years, and some of them last, some don't. This 34R fits my 2007 Odyssey perfectly, and comes with the required spacer for the bottom. Drop it in, hook it up, start the van. No problems. My previous one lasted 7 years, and was still going strong but the top was cracking. In the interest of safety and not getting stranded, I just decided to replace it.Update: This one failed spectacularly after 4 years. One day it was working fine. Next day... nothing. Voltage at 5.5V. Completely dead. I'm on the fence as to whether or not to use Optima anymore. Looking back, the old ones, made in USA, are the ones that really lasted. New ones don't last.Update to the above update: So it turned out that my Odyssey had a faulty A/C relay, and it was getting stuck intermittently and draining the battery when the car was parked. I used a non-standard charger (my solar charge controller) and was able to bring the battery back from the dead. Also replaced the faulty relay in the car. Considering that all the other Optima batteries that I've used have also lasted 7+ years, I'm changing my rating back to 5 stars.

I swapped out batteries on my 06 Ford Taurus the installation was fast and my car fired right up!! I'm totally impressed!! My cousin who is a mechanic says Optima is the best you can get!! He was impressed that I could get it on payments and have it delivered for free through my Prime Membership. I'm stoked!! I bought the 2year warranty offered separately as well. Thank you Amazon!!

I bought recently a battery this battery optimal battery I guess it was January 24 year and it made it through the summer almost and I’ve been charging it in the truck. What a battery tender all through the winter took the charger off three days later. Batteries is dead again I am so dissatisfied with Optima through you. And I buy everything from you so now I’m gonna have to go find a battery somewhere else else buy it and use it and probably have a better chance of it lasting more than a year than you guys sorry to say no more batteries for me. I’ll probably be cutting down on what I buy from you. Have a good day.

For decades now I have been using Interstate Optima Batteries and have loved them. Even though many say that the quality has decreased over the years, especially since operations moved to Mexico, I have still thoroughly enjoyed my Optima batteries and I've had nothing but great experiences with them.I purchased this exact battery (8003-151 34R) for use in my 2010 Chevrolet Silverado 1500 Z71 (5.3L V8). It was a perfect replacement and it did not require the modified base adapter (included in mine). The vehicle cranked up instantly without hesitation. The installation overall was very easy and was very uneventful.As far as the warranty issues are concerned, I believe that Amazon CS has improved dramatically, especially with their relationship with Interstate batteries. I would keep the box just in case it has to be returned, as I'm not sure that local branches will service the battery.

Previously running Optima Yellow Top 34 since 2016, still works and still starts but starting to go weak over the last year so trying the Red Top after 7 years for more CCA and hopefully same level of longevity. Strangely, after installing the battery I remembered ordering the 34R which is model -003, and the box label shows 34R -003, but I didn't remember seeing "34R" on the battery during installation. Sure enough, the battery in the box is a 34 -002 battery, and I don't know what the difference is between these batteries.I checked the battery voltage upon unpacking, and it read 12.4V. I charged the battery over a few hours to full, and it read 13.1V when installed. First start was very powerful with no power sag as the old battery was typically exhibiting when idling. The car sits for days or a week without starting so during these early periods upon installation I'm keeping it charged when not running to maintain battery health, and after a week the battery reads either 13.2V or 13.3V after charging and will drop down to 12.6 or 12.4 after sitting for a couple days slowly discharging, a good sign it's a healthy battery.7 years ago the Yellow Top was $130 less in price and lasted that long without the attention I'm giving this Red Top right out of the box, the old one is disconnected and fully charged with some life left in it. Although Amazon says this does not fit my vehicle it is a perfect fit. Maybe I got lucky getting a 34 instead of the 34R because I don't even know why I'd need one over the other, they look exactly the same.

This is worth it. I needed a battery for my Silverado. I looked for what’s best cold cranking for Montana winters good for 5 years. The price is up there but I see where you can make payments on it if you need to go that route. I’m totally satisfied with this.
