Re: [Amel Yacht Owners] First Impressions: Firefly Batteries.
I never thought I would need to learn so much about batteries, when my original intention was just to sail.toggle quoted messageShow quoted text
We have relatively new AGM’s, and notice that they charge (generator running, Heart Interface) at 40 to 50 amps for an hour or two, and then drop down to about 15 amps. The Heart charger is set for wet cell charging, at the recommendations of the Heart people. As it’s an older model, the only other setting was for gels; there is no setting for AGM.
I had been under the impression that the charger determined how many amps were sent to the batteries. A lot at first, and then tapering to acceptance, then float. With your comment about the Fireflys accepting a lot more amperage than AGM, I now question my understanding. Does the battery also determine how many amps flow in? I had thought that if the charger sent more amps than the battery could handle, the result would be toasted battery or worse. Is there some sort of interplay between the batteries and the charger?
Thanks a always to all those who continue to educate me.
