Absorbed Glass Mat batteries are also referred to as dry cells.
I can remember a number of teachers who would go into convulsions over that usage.
But there is a certain logic to the usage. Since a flooded cell battery is often called a wet cell, then a non-flooded cell could be called a dry cell. Not accurate, since both have liquid, but understandable.
Heck, even a classroom-described dry cell is really a damp cell. Then they become a wet cell and leak.

Not cheep but they work great. For areas that are OK with less light like the bunks I have the warm white, a little softer too.
Yeah, we use them, too. They are particularly good as a patio light if you are prone to forgetting and leaving it on.

My trailer draws 500 milliamps just to run the fridge and detectors and stuff. So 1/2 amp x 24 hours is 12 amp hours per day and nothing is yet turned on.
Then add up the amp draw of what you use and multiply by the time you will use the item. Say furnace draws 8 amps and runs 25% duty cycle or 2 amps per hour and you want it on 10 hours. That give 20 amp hours. Make a sheet for all item you use and add it up.
Take the total and multiply by 2 to get how much battery you need as you don't want to go much below 50%. Or at least have some reserve if you want to run something a little more than planned.
