Re: Battery choice

The advantage of an AGM is less (no) maintenance, the disadvantage is the specific charging requirements.
For a weekender with a trickle charge or low amp outboard alternator and low amp needs, stay simple and stay sailing.

Re: Battery choice

jeff, AGM is no better or cheaper than wet acid UNLESS you can benefit from the diffferences in the design. AGM can sit over the winter witout being charged, without permanent damage. Wet lead takes permanent damage (irreversible sulfation) if it sits for 30 days without recharging, regardess of charge state. AGM will never eat a hole in your clothing. Wet lead will at any opportunity including the carpet in your car. AGM will cost more than wet lead, but it will cost less than the clothing wet lead ate. Wet lead can be topped up if you overcharge it, AGM can't.

And gel batteries require totally different charging, for most users that's not an option.

Whether you chose wet lead or AGM, if the boat sits a a dock most of the time, a good shore charger will pay for itself by keeping the battery properly topped up but not overcharged. If you can't or don't have that option, hook up a small (20-30W) solar panel with controller and that probably will keep the battery topped up just as well. Keeping any battery properly and fully charged may double the life you get from it, and with battery prices skyrocketing that's good economy.

Re: Battery choice

If you want to pay the admission price, you can typically pack more amp hours into the same space with AGMs too. Sounds unnecessary for the OP.
