Restore Chapter 71 Battery | ← Up → |
Model 125 and Model 165 used the 66001-47 battery, also known as an "H-3". This battery was also used on K and early Sportster. Production of these batteries probably stopped in the 1970s or early 1980s, since the Sportster changed to a 12 volt system in the mid 1960s. Some aftermarket companies such as WISCO also produced them, but they too probably stopped production around the same time.
The H-3 measures 4-3/16 x 3-9/16 x 5-3/8 tall. This appears to be an unusual size - attempts over the years to find a similar size wet-cell battery have been unsuccessful. V-Twin Manufacturing sells a replica battery, but around the year 2000, some purchasers reported short battery life. We have no reports on the longevity of current V-Twin production.
Most Hummer owners use a plastic look-alike shell with a smaller battery inside - either a gel-cell or a wet-cell. Several Club members (Duane Taylor, Leroy Lange) sell these shells. Check the "Parts" section.
Original batteries came in at least four different case styles. The production dates are unknown. Rough estimates are shown below. Also shown are two different versions of the aftermarket WISCO brand battery.
