We haven't used these that much but they already have proven to be much better than the 12 volt marine batteries. They last twice as long as 4 of our others and can be discharged more without causing harm.

We spent weeks searching for some good battery's for our golf cart. We found them at a great price at Sam's, and Sam's had them charged and ready to install when promised. They are everything and more as advertised.

I bought 6 of these batteries for my golf cart . The price is very good. So far the batteries seem comparable to other $150 batteries. Time will tell.

4 batteries lasted 2 years in a scissor lift. Trojan and Oreilly Auto Parts GC2 batteries lasted at least four years. I have not had any Duracell auto or gc battery last. I will not be buying any more.

Perfect for Club Car

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 have used a set of these batteries for 5 or 6 years in a golf cart that I use for towing aircraft and driving around an airport. Total use time is typically less than 30 minutes a day. I only charge the batteries when the cart slows down significantly (when battery voltage under load is around 5.6 volts). Fully charged batteries are 6.3 volts. I am very happy with these batteries. They have outperformed other brands I have tried. They don't consume nearly as much water as other brands either. I seldom have to add water. I just bought another set for the second cart.

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.

Bought 8 of these Batterys 8 years ago. Darn it they are now failing. Actually I do have to keep an eye on them in the summer. As for bang for the buck these are my goto for Off the Grid. I will be replacing my 8 failing batteries with these. The Life span was way better than expected

Going on three years,these things are still performing. They run my off grid 30 foot yurt. We have had an apartment sized fridge powered since the day the batteries were connected. Our solar keeps them topped off and healthy. Don’t forget about watering these things and never discharge below 50% capacity. I think I’ll get another 2-3 years of service.
