OPTIMA Batteries OPT8016-103 D34M BlueTop Starting and Deep Cycle Marine Battery

Great battery no complaints

It has been 10 years and 2 months now since we bought this battery. Put it on the boat every spring and took it off every fall. We’ve kept it on a trickle charger over the winter each year. Last week was the first time it didn’t start right up. Still not sure if it’s completely dead, but to go for over 10 years on a boat is pretty darn impressive. The other cool thing about this battery is that you can use a paddle board inflator without the boat being running. Not many boat batteries can do that! Love this battery and hopefully we can keep it going for a bit longer. If not, I’ll buy this same one again.

These batteries are amazing and lighter than standard batteries and last way longer. I use them on an electric motor while fishing and it's the best, last all day.

Excellent produit. Identique à la description: Batterie marine de démarrage et de décharge profonde. Tres bien emballé. Très satisfait.

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.
