The RMHMDU1 is a controlled discharge unit for Hawk 24V batteries — universal 110–240VAC input, real-time voltage/current/Ah/time display, failsafe interlock, fully automatic cycle.
The RMHMDU1 is a purpose-designed controlled discharge unit for Hawk 24V Ni-MH batteries, enabling batteries to be discharged to a defined level before storage or reconditioning. The unit accepts 110–240VAC input and displays four key parameters in real time: voltage, current, amp-hours discharged, and elapsed time — providing complete visibility of the discharge process without additional instrumentation. A failsafe interlock prevents inadvertent connection or operation, and the fully automatic discharge cycle terminates at the programmed endpoint without operator intervention. The RMHMDU1 is an essential tool for Hawk battery fleet management, preventing the capacity loss that results from inadequate discharge management and ensuring batteries are maintained in peak operational condition.
Displays voltage, current, amp-hours discharged, and elapsed time in real time throughout the discharge cycle — complete battery visibility without any additional test equipment.
A hardware failsafe interlock prevents inadvertent connection or premature activation, protecting both the battery and the equipment from accidental discharge outside the intended discharge cycle.
The discharge cycle runs automatically and terminates at the programmed endpoint without operator intervention — operators can leave the unit running unattended, freeing time for other tasks.
Auto-switching universal mains input accepts 110–240VAC, 50/60Hz — compatible with military and civilian power infrastructure across all operational theatres and base locations worldwide.
Proper controlled discharge before storage and reconditioning prevents the capacity loss that degrades Ni-MH batteries over time. The RMHMDU1 is the correct tool for maintaining a Hawk battery fleet in peak condition.
Controlled discharge before storage and reconditioning is essential for Ni-MH longevity. The RMHMDU1 provides the correct, automatic, repeatable discharge cycle to maximise Hawk battery service life.
