Bought two for my boat and they are working great. Hope I get 3 years out of them.

Battery was over a year old

Purchased 2 batteries in March 2017. Both failed after just 14 months .My covered boat is on a lift yet the bilge flooded as a result of these failed batteries. My repair cost to the starter and bearings cost $1100 Invest in a better battery not Duracell

I have a size 24 in boat that is still working - only job is starting 305 SBC and running a few lights. I have a second size 27 just replaced - that was 8+ years old and finally could not crank the 305. I have a Subaru forester with a 4 year old Duracell - still working fine. And - a 1997 F150 with a size 65 - also going on 4 years now All engines are maintained to top condition along with Mercury Outdrive engine. All not-regularly-used (boat/F150) have standby trickle chargers Finally I have a Toro lawn tractor - with a 5 year old Duracell - also kept on a trickle charger when not regularly used. Lead-acid battery chemistry tidbit - leaving battery partially charged for a long period accelerates loss of current suppy capacity. Keep them fully charged as soon as possible after use. Make perfectly sure charging is working properly.

excel expatations

We bought two of these April, 2015 for lake fishing (about 7-10 times per year). Have kept maintained and on slow trickle charge. One died completely after 2 years 2 months.... expected 5 years for our usage. Original boat batteries lasted 8 years.... may be you get what you pay for.... not sure what original type cost in comparison...

When I got it, the battery was filled with full level water, but at 70% charge. I used it with intex trolling motor 40lbs. After 1hr50min, most @speed3, the battery remains 85% charge.

It has worked great but next year will be the real test. For the money it is a good buy.

The process for picking up the battery was easy and the clerk who helped me was exceptional
