H-3 battery 7.4 amps


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.
