So that probably means the output from the generator output is lower than
10 amps.

If the ratio between battery rating and generator output holds between the
big Harleys and the lightweights, generator output might be around 5
amps.

Gene,

I spent some time looking for some kind of specs regarding
Hummer/Model 165 generator output and had no luck. It looks like the
Model 61 6V generator used on the 1936 - 1961 big Harley's is rated at 6
V / 15 Amp. For no really good reason, I would suspect that the
lightweight bikes would not have output that high- maybe 10 Amp

I found several chargers for the SLA batteries - the recommendations are
a 6V / 1Ah charger for batteries from 3.3 to 10Ah capacity or a 6V / 4Ah
charger for batteries from 13.3 to 40Ah - figure that a 13Ah SLA needs
close to the 4Ah rating to charge correctly.

The old H-2 battery was listed at 22Ah. I can't find specs for the H-3
battery, but it looks smaller so would be less, *maybe* somewhere around
15Ah.

Given the recommended chargers / charge rates on the SLA batteries, it
seems possible that the generator with the standard regualtor setup might
actually be charging too much for the SLA batteries... or I could be
completely wrong...

Question is; Will the existing Harley generator actually replenish these gel
cells? Or do you purchase a special charger or discard and replace when
dead?

I found a 6v 4.5 ah gell cell at Tractor Supply for $9.99 they are so small
you could probably install a couple and hook them up in parrallel to fill the
battery box.
