What is the amp hour rating and total charge?
I need a battery to use with a ham radio, for the backyard, at the park, etc.---activities, where I don't have AC access for my power supply. I need to know the amp hour rating for this battery, and the total charge. Most radios/batteries have an initial charge of 13.8 VDC. Amp hours determine how high I can set the power vs. battery drain. Also, what is the difference between the model 81 and 83? They are the same price. Thanks, Steve

N4BYO here. This is not a deep cycle battery. It is not designed to be fully discharged and then recharged. You want a marine battery for that purpose (if used outside). If you want to run a ham shack inside, you should use a gel cell or other high capacity sealed battery. Typical lead-acid batteries will gas when charged and can create an explosive environment in an enclosed space.

Good question. But this is not the type battery you are likely to want for your application. I would highly recommend you look into a RV or Marine type battery designed for deep cycling. I am in a simialr dilema though. Seeking a deep cycle, preferably gel battery that weighs under 15 pounds. So considered this one as well. Actually the size and weight of the battery are my biggest concerns. I need it inder 15 pounds and a half cubic foot by volume. So thought something like this might work. I could live with about 15 ampere hours and my currend draw will be mostly 2 amps but could breifly be as much as 8. Probably very similiar to what you might be seeking. In your case you might simply look into using your vehicle battery to operate your radio. They make a device to attach to bvatteries that keeps a reserve for starting. So you don't habve to worry about using it all with the radio operation. Or you can go the other way and simply add a second auxillary battery to your vehicle. As for home operation, I would simply feed the radio from a battery charger as you are almost certain to have 120 VAC there. If you need 120VAC, you might do as I do. I have a number of Power Inverters that produce 60 to as much as 1500 watts. The big thing with Inverters is to use as small of one as possible or you simply use up battery. Remember the 12 to 120 ratio is 10 to one. So for each amp at 120, 10 amps comes out of your battery. And ten amps for about 3 hours will take most car batteries down to the point they cannot start the engine.
Just as some other considerations, they make a nice little 900 watt 120 VAC/ 9 amp 12 VDC generator that runs on gas mixture for about $80. Good little generator. A good photovoltaic panel might be worth looking into. I have three nice WindGens I built, each can make over 1500 watts and are working with 2 MPH wind. Very compact really. And each cost under $00 to build. I even have a theromocouple generator. But you can forget about that one working if it is freezing outside. Course if it gets tioabout 10 below zero it starts back up again but in the opposite polarity of course. Doesn't concern me though as it never gets that cold here. Oh, and the temperatures are in Celsius. Neat thing though is it uses no fuel and has no moving parts. Only thing to wear it out is the electrolysis causing the two dissimilar metals to errode. But figure that will take about 50 to 60 years.
