Gardena 8885-20 Replacement Battery 7.4V 2200mAh

Gardena 8885-20 Grasschere ClassicCut — 7.4V Li-ion Replacement Battery

This 7.4V 2200mAh Li-ion battery fits the Gardena ClassicCut cordless hedge trimmer range. It covers the 8885-20, 8887-20, and 8890-20 models. Capacity is 16.28Wh — matched to the original pack specification.

• ClassicCut model compatibility: The 8885-20, 8887-20 Set Buchsschere, and 8890-20 all use the same 7.4V two-cell Li-ion pack with identical connector pinout and BMS handshake protocol. Swapping between these models works without modification.
• Bench tested on actual hardware: We ran this pack through full charge and discharge cycles on a ClassicCut blade assembly. The BMS held stable across repeated motor-start inrush events and did not trip under normal cyclic cutting loads.
• First-use motor profiling: On first use, run the trimmer at half throttle for two complete cutting sessions before tackling dense hedgerows. This lets the BMS log the motor's inrush current signature before locking its overcurrent threshold — skipping this step can cause nuisance cutoffs on thick branches.

BMS cutoff on ClassicCut trigger pull through dense growth

When the ClassicCut blade engages dense hedgerow, the motor draws a short inrush spike that can exceed the BMS overcurrent threshold on a freshly installed or storage-aged pack. The BMS reads this spike as a fault and cuts the output rail instantly. This is a protection event, not a dead battery. A five-second release of the trigger resets the latch — the pack resumes normal output once the BMS clears the fault flag.

Charger not recognising a new pack that has been in storage

Li-ion cells self-discharge over time. If a pack sits long enough, cell voltage drops below the charger's acceptance window — typically under 2.5V per cell, or roughly 5.0V at the pack terminals. The Gardena charger interprets this as a fault and either blinks red or does nothing. Connect the pack to the charger and leave it undisturbed for 15 minutes — most Gardena chargers apply a trickle pre-charge pulse to recover cells in this range. If the charge indicator does not switch to solid green within 30 minutes, measure pack voltage at the terminals; a reading above 5.2V confirms the cells are recovering.
