Mike, absolutely right about the 7 years. I should have said that they are not being used for electric drive.
Do suspect that the leading cause of batteries going quickly in an electric drive capacity is that they so often run way down and that, as we all know, is just a killer

The conversation about chargers is part of the conversation about batteries.
Thought you guys should know that the state of California has decided that transformers battery chargers are melting the polar ice caps and should be banned. We have had very good results with these types of chargers. Would those of you who have had experience with chargers when the charger drove power into a battery bank while the batteries were driving the boat please share you experiences. I am thinking of 2 to 6 hours usage of running a small generator and over several years. I would like to know what the experience is with Advanced high-frequency switching design chargers such as Elcon and others.
There has been recent conversations about batteries on this site. As a seller of batteries my view is that cheap is not the way to go but quality at good value are more important. When buying new batteries for a new installation be sure to verify the "core charge" and delivery costs.
Deka (also West Marine SeaVolt) are very adequate for our usage. Lifeline are still the best we have seen over hundreds of installations. Trojan batteries are also well though of. TPPL are becoming more of an option with Northstar and Oddessy being the ones that come to mind. We have seen 7 years as an expected useful life for AGM batteries in our "traction application". We have had very little success with Lithium based sales as the costs are often beyond the budget of our clients. That being said, I would like to know the experience of those of you who have built your own Lithium battery systems and what products you used.
Now for the ad!
My website has new full warranted batteries normally delivered to the dock that I think are good value and are priced to make it easier to go electric in California. The West Marine SeaVolt are sold and delivered nationally.
