Magnetek BT114-0 Crane Remote Replacement Battery 7.2V 2000mAh

Magnetek BT114-0 — 7.2V Ni-MH Replacement Battery (BT114-0)

This is a 7.2V, 2000mAh Ni-MH replacement battery for the Magnetek BT114-0 wireless crane remote control. It fits the BT114-0 remote used to operate overhead cranes and material handling equipment in industrial facilities. Same voltage, same form factor — direct swap into the original cradle.

• BT114-0 remote compatibility: The BT114-0 remote runs a 7.2V rail with a connector and cell pack geometry specific to Magnetek's crane remote platform. This replacement matches that exact configuration — voltage, cell count, and physical envelope — so the remote's internal BMS recognises the pack without fault codes.
• Bench tested on actual hardware: We cycled this pack through solenoid-activation sequences and monitored BMS response under the inrush current spike that relay engagement produces. The pack held voltage above the remote's cutoff threshold across repeated activation events without tripping.
• Infrequent-use charge schedule: Crane remotes often sit idle for weeks between jobs. Ni-MH cells self-discharge at roughly 1–2% per day. If the remote has been sitting for more than three weeks, connect the charger for a full cycle before putting it back into service — a partially discharged pack can drop below operating voltage the moment the solenoid fires.

Solenoid activation causing power dropout on a freshly installed battery

When the BT114-0 remote triggers a crane solenoid or relay, the inrush current spike can briefly pull pack voltage below the BMS cutoff — causing the remote to drop out or reset mid-command. This is more likely if the replacement battery arrived at storage voltage and was not fully charged before first use. Ni-MH cells at storage state have reduced internal current delivery capacity, amplifying the voltage sag during high-draw events. Charge the pack to full before operational use and the dropout behaviour typically disappears.

Remote showing low-battery warning immediately after new cell install

A fresh battery that triggers an instant low-battery indicator is almost always sitting at shipping or storage voltage — not a full charge. Ni-MH packs are not shipped at 100% state of charge. The BT114-0 remote reads cell voltage directly, so a pack at 6.8V will register low even though the battery is not faulty. Put the pack on the charger until the charge cycle completes fully, then reinstall. The low-battery warning should clear once the pack reaches 7.2V under normal operating load.
