The small sealed PowerSonic PS-640F1 batteries were designed for stationary applications - like EXIT signs and electric fence chargers*. When they die, they seem to die suddenly with no forewarning. So, using two of them in parallel with spade terminals gives you the ability to quickly disconnect one of them should one die. Two of them will fit in one of the fake battery cases. There are other brands of the same size battery. I also found some 5.5 amp-hour batteries of the same size, but they are hard-to-find and more expensive.
Most people ride their Hummers on short lower-speed trips, so we're not talking major vibration here. I have used two batteries (the 5.5ah) in my Henderson, and got a couple years of before one died. And that was NOT short low speed rides. The Hen has magneto ignition, but battery-operated lights. Since I don't ride it at night, battery death is not a big concern. Tom (Lisa) says he used them in his K for 4 years. So they seem to be pretty reliable.
I don't know anyone who has used the Power Wheels battery. They don't fit in the fake battery case, so they're ugly.
V-Twin has imported the repro H-3s for 20 or 30 years. They had a bad reputation back then of only lasting about 1 year - and at a cost of $100. Maybe they've improved since then. Perhaps
Raleypc can let us know when his battery finally dies. In contrast, the genuine Harley batteries were very high quality. The big-twin H-2 batteries would last up to 10 years.
In my 1954 KH, I use a
Duane Taylor fake battery case with a Yuasa 6N6-3B lead-acid battery inside.

* Solar electric fence charger - my lawnmower is a 1954 Ford NAA which is still 6 volts. The solar electric fence charger I used to keep deer out of my garden has a PowerSonic PS-640F1 in it. Solar power slowly charges the battery. The battery is connected to a coil - like the ignition coil in your motorcycle. The coil is connected to the fence wire and to a ground rod. When a deer standing on the ground touches the fence wire, he/she gets the same jolt as you get when you touch a spark plug wire. Ouch!
If you remove the battery from the solar charger, and hook wires (I used Romex) to the battery connections of the charger (NOT the fence terminals), add some battery clips to the end of the wire, and Presto - you now have a solar-powered tractor 6v battery trickle charger which you can leave connected all winter long.
