Running a traction battery into deep discharge repeatedly shortens its service life, and this indicator is what gives the operator the charge reference to avoid it. Jungheinrich builds it under part number 51047440 as an LED panel-mount display, seating into an existing instrument cutout rather than requiring new wiring.
This battery discharge indicator is a genuine Jungheinrich part, confirmed under Jungheinrich's own part number 51047440, and it reads state of charge on Jungheinrich electric forklift batteries through an LED panel-mount display. As the truck runs, the module tracks how far the battery has discharged and gives the operator a running visual reference so the truck does not get run down further than the battery chemistry tolerates before the next charge, the core function this instrument category serves across electric lift truck platforms. Panel-mount construction means it installs into an existing cutout on the truck's instrument panel rather than requiring new wiring runs beyond the connection to the truck's electrical system.
The specific Jungheinrich truck models this display was originally installed on are not confirmed, since Jungheinrich's public reverse-lookup coverage for older part numbers is limited compared to more widely documented brands. What is confirmed is the manufacturer and part number match, which is the detail that matters most for a like-for-like replacement: matching part number to part number rather than guessing compatibility from truck model alone. A technician pulling a failed BDI from a Jungheinrich electric forklift can use the part number itself as the primary confirmation that this is the correct replacement display.
