The flooded lead acid batteries have been replaced with Lifeline AGMs on my 30 foot trawler. The start battery is a 4D. The house bank has a pair of 8Ds connected in parallel. The existing 15 amp battery charger was not designed to charge AGM batteries. I am searching for a charger for the new batteries. The marine electrician who installed the batteries has recommended a Pro Mariner Pro Nautic 1250 charger. A Lifeline Battery support tech recommended a Victron 50 amp charger yesterday. A different Lifeline Battery support tech recommended a Pro Nautic 1250 charger today. An Amazon review of the Pro Nautic charger by Aphrael does not recommend it to charge AGM batteries.
I have the following comments/questions:
1. Why should the battery charger need to be 50 amps? I could understand the recommendation, if the vessel was a sailboat. A 30 amp charger would double the output of the existing charger.
2. The Amazon review on 10/17/16 by Aphrael states that the Pro Nautic chargers should not be used to charge AGM batteries. In addition, he states that the output is the same to all battery banks. Is this a problem? I do not have the training or expertise to properly evaluate the review by Aphrael.
3. What other brands of battery chargers should I consider?
Thanks
