The reviews are true. This battery will not hold its charge after a few months. I bought this in March 2021 and died mid-Aug 2021. I even installed a battery tender, but did not need it. It did not make to the winter months. You get what you pay for. Do not waste your money and your time on installing / reinstalling / driving to the store. So much for the copper top!

My battery is 5 years old now and still performing like new. I attribute that to one simple thing; it's connected to a cheap (9 bucks) automatic float charger from Harbor Freight whenever my mower is parked. Lawn tractors aren't used that often so putting the battery on float charger makes all the difference in the world.

I have had this battery less than a year and it has died. I bought it for a whole house generator and it stayed on a trickle charger. I have had smaller batteries on portable generators that stayed on trickle chargers for a few years with no problems. I don't recommend this battery.

My first Duracell battery was purchased on 8/11/2016 and lasted until 5/3/2021 when I bought another. Since buying a smart charger in 2018, I routinely use it to charge the Duracell periodically throughout the year in addition to when I service my lawnmower. The smart charger cleans the lead plates of sulfate thus restoring lost voltage. Failure to maintain your battery will result in a shorter battery life.

When I started bought these for my Scotts tractor they were great. Lasted about 3-4 years with no starting problems at all. Had to replace it about 2 years ago - I had to jump it before I even used it, and then had to jump it about the first 5 times I used it. So I took it back for a replacement. #2 was no better, so on to # 3, which was "OK" for about a year and a half (needed to be jumped randomly). And I was tolf every time that no one else has these problems (wasn't true - lots of 1 star reviews in the past couple of years). Now it's tIme to get a new battery - but it will be from somewhere else. I don't want to have to keep jumping the battery when it decides it's not going to work, especially if I have to pay Sam's new higher price. BTW, my mower has been checked out and it is fine. Definitly a battery problem.

I bought one new in April 2016 and only need to replace it this year, 7 years later. 7 years! I charged it a couple times during each winter, usually around end of Dec and again at end of Feb. I don't know why there are so many negative reviews. Maybe I just got a good one? My 2016 version was 275 CCA. Not sure what the CCA is on these now. I see the cheaper brands at other places are as little as 215 CCA for around same price as these at Sam's.

I bought mine 2/21 but only used my rider 6, 7 times summer of 2021, and same for 2022. Already deader than a doornail. Have had to recharge it about 6, 7 times. I can't recommend it, but who makes a good lawnmower battery, they all seem to be weak.

This is the THIRD Duracell U1 I have had to replace in as many seasons. Battery lasts just beyond 6 month free replacement period (9-12 months) and voltage drops significantly and needs recharging. Has shown repeated failure to start at 1 yr since purchase date, despite higher (365CCA @32) CCA.

The failure of the Briggs & Stratton "compression release canshaft" is giving riding mower batteries a bad reputation. Your battery didn't fail, your Briggs compression release failed and the torque resistance required to start your engine overcame your battery. (It's a starter motor killer too)

I purchased a Duracell battery for my mower from Sam's Club about 3 to 4 years ago ant it was amazing! Started everytime, including the first mow of the season, until the end when I needed to jump it. (i could have bought a new one but since it was end of the season, I wanted to wait until the spring for a fresh one.) No question of which battery I was going to buy, Duracell was fantastic, right? Oh how wrong I was. I am on my way back to Sam's Club to exchange my battery FOR THE SECOND TIME SINCE APRIL!!! Problems? The first one had to be jumped for the first use, was OK for the second, then for the next month had to be jumped every time so it want back on my next Sam's run, The second battery started on the first mow (Yippee, it's a good one?) then for the next 2 months had to be jumped on every mow. I mow about every 1 to 1 1/2 weeks, the mower is garage kept and not exposed to extreme temperatures. I contacted Duracell and was told it wasn't their problem. Their mower batteries are sold/produced by East Penn (apparently name licensing). So another call, to East Penn, where I just got a "thank you for your input" that I would almost guarantee is going nowhere. Duracell, you need to wake up. Your name is on the battery and that is what consumers remember. I was buying a Duracell battery, NOT an East Penn battery. And I now know Duracell makes lousy batteries.
