excellent
What can I say. I got tired of battery's lasting two years. I bought this battery soley to run my trolling motor for my canoe. I use a Minn Kota 55lb Endura motor. On my first canoe trip this year I was able to go 2 and a half days on a charge. That equaled 30+ miles of river. I did paddle some but I also went back up stream through good fishing holes. It holds a charge like no other battery I have ever owned and that includes the days of bass boats and bass tourneys that I have gladly left behind. Thanks for a great product - Butch from Ohio

terminals not the same size
the negative and positive screw-on terminals are not the same size, so one lug and wing nut (the positive terminal) from previous setup doesn't attach to the terminal without modifications, and when I asked for nuts to fit the terminals I was given two of the same size.

Awesome battery - wait for sale

Not much to say, it started my truck engine in the coldest, longest winter I ever knew. The only drawback is it's really heavy. Getting it into the engine bay requires lots of effort and care. It needs some sort of handle or strap to do this alone. Plus I only had a few tenths of an inch to spare in my Tundra battery box.

I would recommend this product to a friend.

7 years and still going

Own fishing boat. Bought 2 of these in April 2007. One for starting and one for trolling motor. Use at least 10 to 15 times a season. Never ever had an issue. I keep an on board charger on them when parked during season and pull them in the fall and keep on a charger all winter. I just bought a new starter battery now as I feel safety is important. 6 miles out and I really want to get back to dock with out worry. Still using the trolling battery. Worth every penny.

I would recommend this product to a friend.

Platinum marine 31 m battery

I have three in my boat. Large amp stereo and takes a lot to start this boat I have. I don't see how this battery could **** out, unless you are charging it wrong with the wrong type charger. I go out every Saturday for over two years and never had problems.huge heavy battery but never have to worry. Does take a while to charge but no issues. Starts every time and I run stereo loud all day long while not running boat.

Good while it lasted

But it didn't last. The battery is door nail dead after four years. I was running it in my old Land Cruiser, no winch, just the engine and normal stuff. Considering how much I spent, and the size of this battery, I would think it would last longer. I've had Optima batteries do better.

Going to purchase

I want to know why any one thinks if they get a three year replacement warranty and they have to use it after a year ,why do you expect a new three year warranty when they replace it with a new battery ? i have a Die Hard Marine Battery i have used since 2008 never a problem and it has set and not been used over every winter,i had to charge it once since i had it,I purchased one of the Optima batteries at Sears and it didn't last two weeks, took it back and got the Die Hard and not a problem yet,so no i will buy this one for my other boat i am rebuilding.

I would recommend this product to a friend.

Battery failed in less than 2 yrs

Failed in less than 2 yrs. more disappointing was the way the warranty works. I received a new battery but the new battery only has 15 months of the warranty left. You'd think that a new battery would carry the 3 year warranty. This may be the industry standard but it isn't right. Wasn't even offered a chance to buy back the 21 months of warranty. Won't deal with sears again.

Outstanding. Shipped direct from manufacturer.

Best value for the price. Made by a first class facility right here in the USA. Shipped directly to me from the factory. Outstanding performance as house and starting batteries on a diesel engine boat.

I would recommend this product to a friend.
