I'm on my second set of these batteries. The first set started going down when they were about 18 months old. And, by the time they were 2 years old, they were barely usable. Foolishly, I replaced them with another set of the same battery. They started going down at about 13-14 months. They are 18 months old now and I doubt that I will be able to get more than another 6 months out of them. My original set was Trojan. They lasted about 6 years. I chose the Duracell to save money. Penny wize ... pound foolish.

I bought 2 of these in 2009 for the house batteries in our motorhome. I just replace them (10/5/2017) with 2 new ones due to becoming weak. And we are full timers in our coach. They lasted 8 1/2 years! You can't expect better than that for this price. I have recommended these to many friends and never had anyone disappointed with them.

Like others have said, you have to keep these watered. I have them series in a boat, they work great running lights, charging phones, and keeping everything cold in an Isotherm fridge overnight. That's a 40Ah draw and 100W of solar puts half that back when it's sunny. They winter on the boat in MD trickled by solar. Got 4 years out of the first set, but I skipped the watering and paid the price. Now I check every spring as part of commissioning, year 4 again and they're going strong.

I use these batteries as the battery portion of my off-grid Solar power system. Though they are not the same quality as the batteries choosing 4x as much, the do a good job for me at a lower cost. I never discharge my batteries past 50% state of charge which helps the longevity of your batteries. People who drain their batteries past 50% week drastically shorten the life of their batteries no matter how much they cost or who makes them. These are good batteries for their cost. An inexpensive way to get started with an off grid lifestyle.

Great Golf Cart battery. Average life in my carts are about 6 years. One of the best thing I like about this battery is that there is about 2 inches of water above the lead. Most golf cart batteries I had have to be checked constantly because just a little evaporation of the acid and the lead is exposed and causes damage. These Duracell's can go 3-4months between fills before the lead gets exposed.

Always, always, always check the battery acid level just after you buy ANY battery. None of the eight batteries that I have bought are up to the proper level. AND, with a new battery---put in real battery acid to give it the best start in life for the longest service life. After it starts with all it was intended for, then you can top off with distilled water the rest of the time. Water vapor is what escapes and needs to be replenished as it is used. Having the right amount of sulfuric acid to start (from the battery acid (available at any auto parts store) will reduce the failures that so many report. Consider a de-sulfinator device to keep it running longer---it is worth the investment and can make a battery last twice as long.

I bought four of these less than two years ago and they are no longer any good. In defense of the battery I have bought many of these over the years (golf cart uses six and RV uses four) and have had solid luck. The four I bought in the Spring of 2015 are all bad...used two different chargers plus the coach charger and they all read bad. The use on these batteries was fairly low and I typically kept them charged even when not in use. They stopped taking a charge late last year with an error reading on my inverter. Super disappointed! I even removed them from the coach and tried to individually charge them multiple times with two different chargers. I'll buy a different brand now!

These Duracell batteries demonstrate good performance in an EZ-Go golf cart with a high speed motor. (Carts are used as main transportation in our community.) Have used them for over 4 years and they perform well. Cart is a 36 Volt cart using six 6 Volt batteries. Quality is good and batteries are priced well below other brands by over 30%. Will definitely install them in my other carts. Purchase process was online and the batteries were ready for pick-up the following morning. Very pleased with the service. Sams made sure all the terminal nuts were included. Went very smooth.

Perfect for Club Car

I bought six of these batteries about 2 ½ years ago at Sam’s, I called and got the specifications on them and compared it other Batteries. They compared very close to the leading batteries that sold for 25 percent higher. I have maintained water (distilled) in them from the onset and to my dismay they did not last to even 3 years. I do use my golf cart every day and my first set of batteries lasted 5 years, this is my second set. I would not purchase them again. In my opinion they are not the worth the money
