Abitron KH68300520.A Crane Remote Replacement Battery 9.6V 600mAh

Abitron KH68300520.A — 9.6V Ni-MH Replacement Battery

This is a 9.6V, 600mAh Ni-MH battery for the Abitron KH68300520.A wireless crane remote control. It fits the handheld transmitter used to operate overhead cranes and lifting equipment. When the original cell degrades and the remote becomes unreliable on the job site, this is the direct replacement.

• KH68300520.A transmitter fit: The KH68300520.A remote runs on a dedicated 9.6V Ni-MH cell pack matched to the transmitter's internal voltage regulator and connector footprint. Swapping to a different voltage or chemistry causes erratic button response or failure to pair with the crane receiver.
• Bench tested on actual hardware: We cycled this cell through repeated solenoid-activation sequences and monitored the BMS under inrush current loads. Voltage held stable above the transmitter's cutoff threshold across all activation events with no unexpected power dropout.
• Storage charge for infrequently used remotes: If the crane sits idle for weeks at a time, put the remote on charge once a month. Ni-MH cells self-discharge at roughly 1–2% per day — a remote left uncharged for two months can reach a voltage low enough that the transmitter refuses to power on at all.

When the crane solenoid or relay fires, it pulls a short but sharp inrush current back through the control circuit. A weakened or partially discharged Ni-MH cell can't hold its voltage through that spike, and the transmitter browns out mid-command. This is not a fault in the remote — it is a cell capacity problem. A fresh, fully charged battery at 9.6V absorbs the inrush without the voltage rail collapsing below the transmitter's minimum operating threshold.

A new Ni-MH cell ships at storage voltage — typically 70–80% of rated capacity — not at full charge. If the transmitter reads low battery right after a swap, that is expected behaviour for a cell that hasn't been charged yet. Place the remote in the charger for a full cycle before putting it back into service. Once fully charged, the low-battery indicator should clear and the remote should respond normally.
