Abitron Mini Crane Remote Compatible Battery 3.6V 2000mAh

Abitron Mini / Mini EX2-22 — 3.6V Ni-MH Replacement Battery (KH68300990.A)

This is a 3.6V, 2000mAh Ni-MH rechargeable battery that replaces part number KH68300990.A in Abitron Mini and Mini EX2-22 wireless crane remote controls. It restores power to the handheld transmitter unit used to operate overhead cranes and hoists in industrial settings. Voltage and capacity match the original specification exactly.

• Mini and Mini EX2-22 compatibility: Both models share the same battery bay dimensions, connector pinout, and 3.6V supply rail. The KH68300990.A form factor fits either transmitter without modification.
• Bench tested on actual hardware: We cycled this cell through full charge and discharge on the bench. The BMS accepted charge correctly, held voltage under simulated transmitter load, and did not trip on solenoid-activation current spikes typical of crane remote use.
• First-use charge for crane remotes: Ni-MH cells ship at partial storage voltage. Connect the battery to the Abitron charger for a full charge cycle before the first use in a crane environment — operating at partial charge can slow E-stop signal response, which matters in safety-critical applications.

Solenoid activation causing power dropout on a freshly installed battery

When the remote triggers a crane solenoid or relay, the inrush current demand spikes sharply for a fraction of a second. A Ni-MH cell at storage voltage — typically around 3.3V — has higher internal resistance than a fully charged cell at 3.6V. That resistance causes a momentary voltage sag that can cross the BMS undervoltage threshold and cut the transmitter off mid-command. The fix is straightforward: fully charge the battery before first use. After a complete charge cycle, internal resistance drops and the cell handles activation spikes without dropout.

Remote showing low-battery warning immediately after fitting a new cell

A new Ni-MH cell arrives at storage voltage, not full charge — usually 3.2V to 3.4V rather than the 3.6V the transmitter expects. The Abitron Mini reads that as a low-battery condition and flags the warning straight away. This is not a faulty battery. Connect the cell to the Abitron charger and run a full charge cycle. Once voltage reaches 3.6V, the warning clears and the transmitter operates normally.
