I order 4 gel marine battery and got them the same day everything looks good haven’t connect them yet is one thing I noticed is that only one battery came with bolts nuts the other 3 didn’t come with it it makes no sense but besides that everything looks like the pic

What can you possibly say about the Optima Blue other than this battery is the best I've ever used. Installed two in my boat and I can now run the stereo for about 4 hours before having to switch to the 2nd battery.

Very good, better than expected. My Mastercraft Prostar V8 turns over quicker, starts right off; it never did before even when my previous lead-acid car type battery was new. Will not disappoint. Saved about a hundred dollars, shipping included, over purchasing it from the local auto-parts store and didn't require a core charge and all that fuss. Was packaged very well.

Such a great battery. I use it in my mild compression 2276 VW sandrail. I really like the battery accessory terminals on this battery. This is my second 34M battery in this sand car. The first one lasted more than 12 years before I decided to replace it. I also picked up an Optima Digital 400 battery charger... I love it as well.

Our boat has two of these, one for engine start and the other as house battery. In 12 years of boating, I replaced one at 6 years and the 2nd one at 12 years. Neither failed in service, I changed them as their electrical characteristics changed and they held a lesser charge. I never had a fail to start or a condition where I had to operate the manual parallel to start the engine.

Now THIS is a battery. Had to replace mine and went with these because it can be difficult to get in the boat and check levels of water in flooded batteries that you have to open. I noticed that these while a bit heavier, they do hold a charge much longer from what I have seen thus far.

These are awesome just do your research and buy the one for your needs. If you need a deep cycle battery don't buy a cranking battery and be disappointed

Using two in my RV and they've handled all the power requirements with no issue. Being more compact than regular lead/acid batteries is a bonus. I'll purchase again in the future.

Optima's are great batteries. This is the house battery for my VW Camper Bus and its perfect for the job with no risk of leaking.

This is my fourth optima battery. I have had excellent experience with them. I bought this one to replace a Sears platinum battery that was more expensive than this battery when I had to replace the Sears for the second time in 5 years. I have had my other optima batteries for 7 years and they still work great. These are an excellent choice for boats, and I even have one in my car that has been going for 8 years. I love these batteries.
