I am thinking of purchasing a pair of Optima batteries. Any opinions as to how good they are? Will they last longer than other batteries? The cranking Amps are quite high for the starting battery and that is what I need.

They are expensive but give twice the CCA for the same weight conventional battery.
The high end builders use them with excellent results.

I installed 3 of them a little over a month ago. 1 starting battery per engine and 1 for the house. One of the starting batteries was discovered to be bad right out of the box. But, the battery distributor replaced it with another no questions asked. I've only got a little over 80 hours on my engines but am very pleased with them so far.

I love mine. Be careful with a complete discharge. One of my kids was playing on the boat and left the spread light on for a couple of days (I forgot the master battery switch) and ran it down dry. The battery dained down to -0.0 and couldn't be revived.

The good news is that with a 18month non-depreciating warrantee the battery was replaced without a question asked with a brand new one.

Hard to beat that.

I have a pair in my boat, A starting battery and a dual purpose up front. They work well and they are little lighter than the others.
The best place I found to buy these batterys is Sams Club as they have the best price and you have a place you could take them back if you need!

I have two D31M Optimas. Optima and Interstate are owned by Johnson Controls. If you have an Interstate Battery Store near you; you'll pay less for the Optima battery. AGM & Battery FAQ

It's the only battery I will use. Used them for years in very harsh race car situations as well as boats and every day cars. We broke the bottom off one and used it for a month with no loss of performance. It used it sit 6" away from 1000 degree exhuast for long periods of time as well.

When buying, do some shopping on the net. You can get some great buys on Optima batteries and really save some $$$'s.

Thank all of you for the replies. It put my mind as ease and I will be purchasing them. One more question. I have a guest charger on board. Will this work with these batteries? I heard that some of the newer batteries cannot be charged with this charger.

Optima can be charged by all regular and the onboard guest chargers.

Three (3) D31's in the boat and in every vehicle I drive and the EZ Dump trailer. The '99 Sub has two that are 6 1/2 years old. Can't find a reason to replace. Started in the cold of our last NE winter.
They are like the energizer bunny - keep going..going..going..going.

The best part of having them in the boat is that they will not freeze. I leave them in the boat all year. Even when not charging, they do hold a charge a lot longer than a acid battery. You can read about all the other plus's for yourself. I'm a believer.

BTW - all are yellow top's.

I have 2 Optimas in my boat. They are 7 years old. I have had the boat for a little over 2 years and they have been perfect.
