I thought they were made by Johnson Controls???

I just put mine back in the boat for the season and they showed 90% and held it with a load tester in test position for 10 Sec! I topped them off with a charger and I'm good to go! BTW this is their 5th season.

One thing that was not discussed is the fact that regular "Plate" style batteries with electrolyte sloshing around do not like the hard bouncing and abuse from big water and will or should not last like a spiral or gel type battery. But then again it's hard to argue the price difference but I'll stick with the maintenance free Optimas.

They are maufactured by Optima Batteries Inc out of Aruora Co. You are exactly right, even though alot of money goes into the reasearch in making lead acid style batteries more capable of holdng up to the rough atmosphere that marine life offers you still simply cannot beat the Optima. But as you know, price reflects that.....

we run optimas in our race cars and in my boat. Great batteries, they can be fast charged if you buy a smart charger with the Absorbed Glass Mat setting, they can be charged at up to 25amps with one.

Do it all the time between heat races.

There are many variables that effect a batteries performance and different type batteries will perform much differently based on the environment it resides in. I have purchased around 10000 batteries over the past 20 years in my job, and from the majority of the major companies mentioned in the above threads.

In my "opinion" DEKA (GELL style) makes one of the best batteries on the planet. This opinion is based on many engineering hours testing and the manufacturing methods East Penn Manufacturing (DEKA) uses in the constructing of their batteries.

If they (gell) are charged correctly they will last a very long time. If they are over charged their life will decrease up to 60%. This is a problem is a standard auto/marine charging system. Gell type batteries are also temperature sensitive and the float voltage should be regulated based on the battery temp. Again this is very difficult in a boat. I attached a chart showing float voltages as a reference.

Also gell style batteries work very well in deep cycle applications. Again as long as they are recharged correctly.

Gell type are best if you do not mind putting out the money up front and can properly maintain them. I use standard led acid batteries (Walmart) because they are cheep and last a long time when maintained.

I hope this wasn't to much information, just an opinion.

Deka is what Skater used when they built my boat.
Deka Part # 24M7
875 cca @ 0 degrees F
1000 MCA @32 degrees F

I could not find another battery that compares

Odyssey batteries are smaller and have more output . Optimas were ok to me but not great.

I have both Trojan house batteries and Bass Pro(Made by Dekka) for starting batteries. The Bass Pro branded Dekka's are the best for the money spent in my opinion.

Also make sure your shore power charger is recomended for AGM if you go that route.

Walmart/Sams is EXIDE . try and find the distributor in your area and they will sell you direct cheaper than walmart and Sams,

Also ask about there blims/seconds . I bought the Blue top Exide gel cell for 50.00 each
