Re: Battery charger "reconditioning" mode, water loss, and SLA batteries
My point was that "if your ONLY REASON" is difficulty in access for watering, there is another, less expensive solution than AGM or gel batteries.
As for the "high acceptance rate" claim, it’s true for the batteries, but I’ve seen few boats with charging systems that can provide enough amperage to take advantage of it. The lower self-discharge can be an advantage, but if you’re a full-time live-aboard, it doesn’t mean much. "Ease of placement" might be an advantage, but on a boat with adequate space for flooded batteries it’s a moot point.
There are certainly places and applications for AGM and gel cells. I use two of them, one mounted sideways to fit a space. But they’re not the be-all-end-all solution, nor the best solution for every application.
