AGMs hold a charge longer when sitting. And no watering or corrosion is really nice. Forget the money.. just cry once and get them. You'll never look back.
That is about it. They are widely used in the marine world where vented gas from wet cells has nowhere to go but the bilge. They are used in aviation too. Planes are not always level & acid does not go well with aluminium.
I got rid of the wet cells after a couple of years & went straight to a single AGM 4D by Lifeline. A 4D gives very similar amperage to 2 6V in series.
That 4D gave 9 years service life of over 150 nights use each year. It also sat, disconnected & with no maintainer, for 7 months straight each of those years.
Subject to Covid 19 our 2nd AGM will begin it's 3rd year in a month or so time, after more than 8 months no maintenance this time.
If money is going to be spent on an AGM it might also be a good time to upgrade what is probably a cheap & nasty converter/charger to a multi stage smart one with a wet,AGM,gel ability.
