Large batteries systems used in heavy industrial and commercial equipment, the telecom industry or renewable energy systems require emergency recharging and often at the most inconvenient times and places.  ALTEN Battery Chargers recharge flat batteries quickly and efficiently, anywhere, anytime. ALTEN stationary models automatically backup batteries used in critical service applications to ride through primary battery charging trouble periods.

Powered by Hatz 1B20 diesel engine, the DUKE 120 is a 12 VDC battery charger/generator that delivers 1.7 kW peak power and 30.2 kWh from a standard 4.5 gallon tank of fuel. Stationary EX models have a 20 gallon base-mounted fuel tank for approximately 80 hours of run time versus 18 hours on the standard 4.5 gallon top-mounted fuel tank.

All DUKE series battery chargers/generators are built on an all-welded, powder coated aluminum frame for a durable, corrosion resistant finish.  Check out our models and optional add-ons below.

Remote Communications

Remote Monitoring System
With MODBUS support, the DUKE Remote Monitoring System provides Internet browser-based remote access to the engine controller to view, adjust, start and stop the DUKE anywhere Internet access is available. The DUKE RMS includes serial, Ethernet and USB ports.

Hot Weather Kit

Hot Weather Kit
A recommended add-on for any application where ambient temperature is expected to exceed 30'C (86'F). Increased ventilation to the engine is provided by a filtered DC-powered fan and ductwork, and is controlled by an on-board thermostat.

Cold Weather Kit

Cold Weather Kit
A recommended add-on for any application where ambient temperature is expected to fall below -10'C (14'F). An on-board thermostat controls an 80 watt block heater, and a glow plug is added to the engine start sequence.

Auxilliary Fuel Kit

Auxiliary Fuel Connection
For applications where an alternative diesel source is available, such as a vehicle fuel tank, an auxiliary fuel connection is available and includes connections and fuel pump.  NOTE: Use of diesel fuel not recommended by the engine manufacturer may void engine and battery charger warranties.
