Helmar On-Board Battery Charger 120V 60Hz Input – 20-261

The Helmar Inc. 1 on-board battery charger recharges a lift truck's battery from a standard 120 volt, 60 hertz wall outlet, plugging directly into the truck's on-board charging port. Input rating is confirmed at 120V 60Hz, the standard household and shop-outlet supply used across on-board charger applications in this class, and the unit fits Yale equipment. The charger measures 2.75 by 4.75 by 10 inches, a compact footprint built for on-board mounting rather than a stand-alone charging bay, so it occupies the same physical space as the unit it replaces without requiring a bracket change.

Because the confirmed record does not carry a DC output rating or target battery voltage, matching this charger correctly means confirming the output voltage and connector type against the charger currently on the truck rather than relying on the wall-input rating alone; two chargers with identical 120V 60Hz input can still differ in what they deliver to the battery. This is standard practice for on-board chargers generally, since the wall-side input rating only describes what feeds the unit, not what the unit produces. For a Yale-equipped fleet running this charger class, confirming the physical footprint and the DC output side together is what keeps the replacement a drop-in swap rather than a rewiring job.
