    • Finally a solid battery!
Product Packaging: Retail
Reliable power to start your diesel truck is crucial. Especially when you have two batteries paralleled, they both have to be on the same page. I had tried 3 separate times with flooded Interstate batteries from Costco, but they just couldn’t handle the demand of a diesel truck. I finally bit the bullet on these AGM Redtop Optima’s and I couldn’t be happier. They start my truck fast every time and charge faster with the alternator so it doesn’t have to work as hard and lasts as long as possible. Highly recommend for a diesel truck application! ... show more

Fits 88 Buick Reatta. It's a good quality battery, and you pay for that quality. Is it worth it? To me, it is.

    • Each Optima Battery Has Lasted Well Beyond 8 Years
Product Packaging: Retail
By no means was the Optima battery that I was replacing getting weak, or giving out. I merely replace my Optima batteries after about 8 years so that I don’t get stuck having to buy a new battery while I’m on the road or out of town. This is my third Optima car battery. They have always been a solid choice, and perform beyond my wildest expectations. That being said, I do charge my battery occasionally (about every 2-3mos) to keep it topped off. I have never had a dead battery with an Optima. 🔋✨ ... show more

Original hold-down bracket won't work due to thicker base rim. Fortunately, the mfr sends a replacement in the box that works. Battery is just slightly smller than original type 78 making it easy to change.

    • NOT RECOMMENDED FOR COLD ENVIRONMENTS.
Product Packaging: Retail
WARNING, DO NOT BUY IN COLD PLACES!! I purchased this battery, installed it and used it for just a hair over a year, it survived the first winter fine, this winter it frozen completely, complete failure, with multiple cells having cracked. Also be warned that depending on car model, you may need a different ground base. Due to the shape, the battery is smaller than it seems when compared to a box battery. This can lead to the battery shifting, disconnecting, or even cause shorts that can blow fuses. ... show more

    • NEVER ever completely discharge an Optima.
Product Packaging: Retail
I have an Optima that is 21 YEARS old & still starts my 4cyl pkup!! It has been in constant use & NEVER run down. Is that a record?? I'm not sure they are still made to this standard. Even with an Optima charger I've had little luck revieving a dead Optima. With almost NO corrosion or maintence, I feel they are worth the extra cost for a vehicle in regular use. They DON'T like being charged like a regular battery but can be jumped to get going again, don't trust they will accept enough of a charge to start you again once you shut off. Trickle chging has worked best for me. ... show more

    • Perfect For My RV
Product Packaging: Retail
I bought this battery for my RV. Not a motor home but a trailer. For my energy consumption needs this is the best priced battery. Let's look at some basic specifications. Cold Cranking Amperes is a useless specification when the battery is to be used in an application where an engine or large electric motor is not used. For RV owners the most important specification is the Ampere Hour rating (AH). In short, the AH rating is the capacity of a battery to hold electricity. Just like a large glass holds more water than a small glass, batteries hold more or less electricity than one another, but in the case of batteries, they have different capacities even if they are physically the same size. This battery is rated at 50 AHs. That means that if you had all the lights on at the same time in your RV and they consumed 5 amperes, this battery would keep them lit for 10 hours (50 amp hours divided by 5 amps equals 10 hours). If the electric load was 15 amperes then this battery could run this load for 3.33 hours, and so forth. When purchasing a battery for your RV you can determine the better buy by dividing the cost of the battery by the AH rating. A $150.00 battery specified to offer 50 AHs equals 3AHs per dollar. A $130.00 battery rated at 10 AHs equals 13 amps per dollar, making it a far more expensive battery - UNLESS 10 AHs is all the capacity you need. Replace the incandescent lights in your RV with LED lights and the energy needed to light your RV will be cut by 75%. Also remember intermittent electricity use like your water pump and overhead fans. ... show more

Product Packaging: Retail
I purchased this battery for my 2006 GMC Envoy in Nov of 2009. As you can see from the date of this review it's now March of 2015 and at the risk of jinxing myself, its still going strong. I've normally purchased Sears Die Hard batteries for my vehicles thinking that they were the best, but I don't like the fact that they sell their different grades of batteries by the number of months that they will last. There's a reason that the majority of race teams both, street and off road, use these batteries, they are top notch. Period. I drive the crap out of my car daily. It's an '06 with a little over 200,000 miles on it. For what its worth, this battery has held up very well for 5 years and 4 months and I don't anticipate having to change it any time soon because it still charges as high and as fast as it always has. Maybe I just got a good one? I'm not that lucky usually. Personally when I buy a battery I want to put it in my car and never have to think about it, or worry about it for long time and that's what this Optima 78 has been for me. ... show more
