Gardol GAM-E 33/1 Li 18V Replacement Battery 4000mAh

Gardol GAM-E 33/1 Li 18V Li-ion Replacement Battery

This 18V Li-ion battery pack replaces the original unit in the Gardol GAM-E 33/1 Li cordless garden tool range. It fits hedge trimmers, grass shears, and pruners that run on the GAM-E 33/1 Li platform. Capacity is 4000mAh (72Wh), matching the OEM cell specification.

• GAM-E 33/1 Li platform fit: These tools share an 18V rail and a common battery bay connector footprint. The BMS in this pack communicates charge state back to the tool’s control board using the same handshake protocol as the factory unit.
• Bench tested on actual hardware: We cycled this pack through simulated hedge trimmer load profiles repeated inrush spikes at trigger pull followed by sustained blade resistance. The BMS held the overcurrent threshold without nuisance tripping across all test cycles.
• Break-in procedure for GAM-E 33/1 Li tools: On first use, run at light cutting load for two full discharge-charge cycles before tackling thick hedgerow. This allows the BMS to profile the motor’s inrush current and calibrate its overcurrent trip threshold accurately before you push the tool hard.

BMS cutoff on motor-start inrush in Gardol GAM-E 33/1 Li tools

The GAM-E 33/1 Li motor draws a brief inrush spike the moment the trigger closes often three to five times the steady running current. A new or cold battery pack that hasn’t profiled this device’s motor yet can interpret that spike as a fault and cut the output rail. The BMS resets within a few seconds, but if it trips repeatedly on the same trigger pull, the pack needs conditioning cycles. Two light-load discharge cycles recalibrate the overcurrent threshold to match the actual motor signature.

Charger not recognising the pack after extended storage

Li-ion cells stored for more than three months can drop below the charger’s minimum acceptance voltage typically around 2.5V per cell. When this happens, the charger sees the pack as defective and refuses to begin a charge cycle. Place the pack on the charger and leave it for 2030 minutes regardless many chargers run a trickle pre-charge at 100mA to recover low cells before switching to normal CC/CV charging. If the charger still shows a fault after 30 minutes, check the rail voltage at the pack terminals below 10V across the 18V pack means cell recovery has failed and the pack should be replaced.
