Re: Dolphin power 1 battery chargers

Ross and Donna,
It is hard to say for sure. I had the same "non-changeable" Dolphin chargers on 2003 BeBe SM 387. In about 2007, I wanted to replace almost 4-year-old original Delco France Freedom batteries with FullRiver AGMs. I sent the FullRiver AGM charging parameters to Dolphin and asked them if I could install them. Their response was "Yes," which was obviously what I wanted to hear. I do not think it is that simple.
I believe the more exact the charging parameters match the battery, the longer the life of the batteries. Those AGMs lasted about 4 years...not bad for the price I paid. For full-time cruising, regardless of the battery you buy (except for Lithium), my advice is hope for 3 years and if you get 4 years, consider yourself lucky. The worst set of batteries I bought was the set to replace the above AGMs. They were Varta Freedom batteries bought in Greece for 3,000 euros for 13 batteries. They began to fail in 6 months and were completely gone in 12 months. Varta did nothing! The measure of the experience was not the failure, but what Varta did. Of course, they suspected my use and chargers. That was a bad assumption on their part, even though I suspect that it is a valid assumption more times than not. The chargers were fine and I never allow the bank to go lower than 70%...you were wrong Varta and I hope many read this.
Lastly, do not forget the 24-volt alternator. It charges the battery bank more than you realize and if your SM has the original, it does not have a smart regulator. Installing a smart regulator can probably do more to extend the life of your battery bank on a SM than anything else you do.
