About this replacement
NBB Planar-C / AKK0600 — 9.6V Ni-MH Replacement Battery (2.260.1010)
This is a 9.6V 2000mAh Ni-MH replacement battery for the NBB Planar-C wireless crane remote control transmitter. It fits the Planar-C and AKK0600 handheld units used to operate overhead cranes and lifting equipment in industrial and construction sites. Capacity is 2000mAh (19.2Wh), matching the original specification.
- Planar-C and AKK0600 compatibility: Both models share the same 9.6V NiMH cell stack, connector pinout, and charge circuit — one battery fits both transmitter variants without modification.
- Bench tested on actual hardware: We cycled this battery through charge and load discharge on crane remote test rigs. The BMS held stable voltage across simulated solenoid activation events without tripping the protection circuit.
- Storage charge for infrequently used remotes: If the transmitter sits unused between jobs, charge the battery once a month. NiMH cells discharged below their floor voltage during long idle periods can develop high internal resistance, causing the remote to read low battery or fail to power on even after a fresh charge.
Solenoid activation causing power dropout on a freshly installed battery
When the transmitter triggers a crane solenoid or relay, the inrush current drawn in that instant is significantly higher than standby draw. If the battery cells have high internal resistance — common in aged or deeply discharged NiMH packs — voltage sags sharply at that moment and the remote's under-voltage protection trips. The transmitter resets or cuts out mid-operation even though the battery shows sufficient charge at rest. A fully charged, low-resistance cell handles the inrush without the sag, so replacing the pack and charging to full before use eliminates this fault.
Remote showing low battery warning immediately after a new pack is installed
NiMH batteries ship at storage voltage — typically 1.1–1.2V per cell — not at full charge. A 9.6V eight-cell pack at storage sits around 8.8–9.0V measured at rest. The Planar-C transmitter interprets this as a depleted pack and triggers the low battery indicator before you even operate a function. Fit the battery, place the transmitter on charge, and allow a full charge cycle to complete. The low battery warning will clear once cell voltage reaches the nominal threshold.
