    • Best Marine Battery !!
Style: Single
This is the ONLY battery you'll ever see in my boat !! Holds a charge a long time and can go the distance running lights and sound system for hours then still crank the boat up like a boss. I keep a tender on it all winter, then in Spring it fires my boat right up like it was brand new !!

    • Update: OK, customer service doing the right thing
Style: Single
I bought this battery a bit over 1 year ago (on May 2023). Even after completely charging the battery on an OPTIMA charger, the battery would barely crank over a 20 hp outboard motor. I should have tried to return the battery then, but it still worked (barely), and I needed it for the boat. In Nov 2023 the battery was placed on an OPTIMA charger over the off season. Once again, this spring, the battery is still weak. The battery is not much better than the OPTIMA battery I replaced which I used for 9 years! Very disappointed and I will not be purchasing OPTIMA batteries again. UPDATE: I called customer service and explained the problem, and they will honor the warranty. Following the phone conversation, I got an email that said: We will need a picture of your proof of purchase and a picture of the bar code on the side of the battery Put your case # in the subject line and email to [email protected] I have yet to send in the info, but it seems like I will be able to get a replacement (I'll update here if I do not) So, great Optima customer service! (I knocked off one star as I did receive a faulty battery) Last update: Replacement battery just arrived!! Added back a star ... show more

    • Quality
Style: Single
With the price of batteries these days , I hated to spend the money, but this battery is lighter than most. Making easier to take in and out of my boat. High quality and long lasting charge.

    • Optima trash!
Style: Single
Warranty process is painful. Then some one tells you to take the defective battery to ups drop off and then they'll issue a refund. Would not ship a replacement. Say 30 day return, that's not true. When filling out a claim it say non returnable. Should have gone to Autozone!!!!!!!

    • Works perfect!!!! Heid up all day
Style: Single
Much lighter than a walmart battery so far so good, we will see if it holds up with a all day fish, I will update later Upadate 4/20/16 Used this 8 hours on a 52 lb minn kota, It was windy and I used it hard hard figured it would go down before I left the lake, I was afraid it would not start my 25 hp motor, At end of day my trolling motor has a gage to check battery reserve and it said 3/4 full is that impossible so I had another battery checker and it checked 3/4 full can that be true, can that light of a battery hold that kind of reserve, If this is true and I guess it is,this is the only battery I will ever have. Finally something that gets me thought the day and I can carry from the boat that does not weigh a ton, I will update if things change. Update 5/3/16. Ok had it out 11 hours used hard hard, showed 12.2 volts, check with meter showed 1/2 charge left, unbelievable only battery I will own know matter the cost. Will update after a year 5/1/17 Ok bought a bigger boat with a older foot controlled trolling motor, the battery. We fished and used it from 9:00 am until 8:00 a 11 hour day of pretty much nonstop. After about 11 hours battery died. I still am very happy, if I had to do it over I would of bought the D31M check it out. It has 75 ah. That would have enough to run the day. Just a thought. It not that much more to buy the 31. My friend has a 31 and has had it for years maybe 6 or 7. Still works perfect. ... show more

    • Old Battery?? Apparently not.
Style: Single
The battery showed up with no date stickers. The only time I've heard of this happening is when someone doesn't want it known just how old the battery is. I emailed Optima about this and never got a response. I probably bought a battery that has been sitting on the shelf for years. Thanks a lot Optima!! * * Before I returned it I decided to call Optima and got through to customer service fairly easy. Apparently the Non-Spillable tag has the date code in it. First number (5 on my battery) is the year it was made, 2025. the next 3 numbers is the days it was made (044 on my battery) meaning 44 days into the year or February 13th. It would have been nice to have got this info the easy way but now I am happy I have a fairly new battery. I also learned that the Optima's 3 year factory warranty is honored on purchases through Amazon Now I'm very happy!! ... show more

    • Updates: Less than a year and won’t hold charge—junk
Style: Single
I’ve updated from one to 4 stars because Optima and Amazon worked to get me a warranty replacement. Used less than 3 months as a deep cycle accessory batter (3-5 amps total draw during that time). Used a float charger especially designed for AGM batteries; battery was never depleted. Voltage 3.5v today and won’t take a charge. YTD Sport was the seller (through Amazon) and punted to Optima. “Customer service”. At least with a brick and mortar store you take it back and they take it—no hassle. Live and learn. ... show more
