Hiab 077 HIDUO Crane Remote Replacement Battery 7.2V 2000mAh

Hiab 077 HIDUO / 088 HIDUO Series — 7.2V Ni-MH Replacement Battery (2.260.1022)

This is a 7.2V, 2000mAh Ni-MH replacement battery for Hiab wireless crane remote controls, including the 077 HIDUO, 088 HIDUO, 088CL, and 095 series. OEM part number 2.260.1022 (also cross-referenced as 22502010). It fits the handheld transmitter units used to operate Hiab loader cranes and material handling equipment on job sites.

• 077 HIDUO and 088 HIDUO platform fit: These remote models share the same 7.2V cell pack configuration, connector pinout, and physical housing dimensions (127.20 × 53.40 × 22.30mm). One battery SKU covers all of them because the transmitter circuit draws from the same voltage rail across the range.
• Bench tested on actual hardware: We ran this cell pack through charge cycles and verified the BMS handled the inrush current spike that occurs when the transmitter activates crane solenoids. No mid-operation voltage dropout was recorded at full charge.
• Infrequent-use charging protocol: Hiab crane remotes often sit unused for weeks between jobs. Charge this battery at least once a month during idle periods — Ni-MH cells left discharged can develop voltage depression that prevents a normal charger from recovering them.

Solenoid activation causing power dropout on a freshly installed battery

When the transmitter commands a crane function, solenoid coils pull a short but sharp inrush current — often 3 to 5 times the steady-state draw. A Ni-MH cell at partial or storage-level charge can't sustain the voltage under that spike. The transmitter momentarily drops below its operating threshold, resets, or cuts the output signal entirely. This is not a fault with the remote or the crane — it is a voltage-sag issue. Charge the battery fully before first use and verify cell voltage reads at or above 8.4V (full charge) before operating.

Remote showing "low battery" immediately after fitting a new cell

Replacement Ni-MH packs ship at storage voltage — typically around 6.0–6.5V for a 7.2V pack — not at full charge. The Hiab transmitter reads this as a depleted battery because that voltage sits near the low-threshold cutoff. This is not a faulty cell. Connect the battery to the OEM charger or a compatible Ni-MH charger and run a full charge cycle before inserting it into the remote. The low-battery warning should clear once cell voltage climbs above 7.0V under load.
