These can't be the same Duracell as other stores. I'm on my second one in 2 years. First one, a terminal cracked. This one it has been less than 12 months and after starting a 150HP Mercury Pro XS one time and then running electronics (6.5 amps of draw) for 6 hours I get a low battery alarm. The battery had been sitting on Noco charger for over a month. The battery was definitely full charged. Why only 18 Months Warranty? Because of the Price or quality? I'd rather pay a little more and have 30 month warranty and a better battery.

I recently became a member with a groupon. My husband went with me to look around and came back really excited that you had these batteries available for his boat at an excellent value. We bought them online checking for availability to pick up at the store that had them.

Battery was good while it lasted. We kept it on a Battery Saver most times, since it was used in a tractor. It got left unplugged and was fully discharged one time and would never hold a charge again. After 100% full charge at 2Amps it dropped to 4.3V in less than ten hours without use. Not the best battery that I have used.

The batteries were shipped and available for pickup exactly as promised. But...I ordered the batteries online for store pickup, then found them for sale at a lower price in the store! Not a sale price either. I needed 3 from the same lot; the store had 2 and would not meet their in-store price for my online order. But either price was a fair price, so this is a minor “gripe.” (No actual or specific price is mentioned)

Bought total of eleven, three for diesel start engines (2 drive and one generator) and eight for the boats house bank. The eight used for the house are shot after less than 4 years. Would not buy again since we got double that with Trojan brand batteries. Will now convert to lithium batteries.

I have purchased several different batteries over the years, and opted to try one of these batteries because lead batteries have performed very well for me, and these claim to last longer, however they don’t. Best I have done with these batteries is 3 years. First one died 15 months from purchase, yes it was replaced, however it’s more the addravation of dealing with it. Second battery made it 3 years. My batteries are on a maintainer for AGM batteries year round, when not fishing, so that takes maintenance out of the equation. Next, during owner ship I was not able to troll on high for more than 4 hours with 2 fully charged batteries (24 v). This is a problem, considering 31 series leads get me all day. I say buyer be ware.

These batteries worked well until I accidently left the key on in my 1990 shuttle bus. The batteries were completely drained. Now I cannot get them to charge to 12V. Maybe I got a bad batch? I'm going to trade them in and try again.

Worked fine for 22 months then within a month stopped taking a charge. That's nowhere near long enough to justify the price. I won't get fooled again.

My first set is four years and still going strong.
