About this replacement
Wolf Garten Cordless Shrub & Hedge Shear — 3.7V Li-ion Replacement Battery
This 3.7V 6000mAh li-ion cell replaces part numbers 7086-918, 7085066, 7085918, 7086918, BS 100, and 5031-M6-0011. It fits the Wolf Garten Power 100 cordless shrub and hedge shear, along with the Classic 60 Mit, BS80 Plus, and MTD5031-M6-0016 among others. Voltage and capacity match the original 22.2Wh specification exactly.
- Shared platform compatibility: The Power 100, Classic 60 Mit, and BS80 Plus all run the same 3.7V rail with an identical connector footprint and BMS communication protocol, which is why one cell covers the full range.
- Bench tested on actual hardware: We ran full charge/discharge cycles — the BMS held voltage steady under cutting load and triggered the low-voltage cutoff cleanly without a hard drop-off.
- No break-in required for li-ion: Unlike older NiMH packs, this chemistry delivers full capacity from the first charge — no cycling ritual needed before putting the shears to work.
Why cell dimensions matter in compact hedge shear handles
The Power 100 uses a narrow handle cavity — 66.40 x 40.00 x 18.60mm is the precise envelope this cell must fit. A cell even slightly outside those tolerances will bind against the housing or leave the connector misaligned. This replacement is sourced to that exact dimension, not approximated from a similar-looking pack.
Shear won't power on after storage — here's what's happening
Li-ion cells stored below roughly 2.5V trip an over-discharge lockout in the BMS, and the shear shows no signs of life even when placed on charge. The fix is to connect the charger and leave it for 15–20 minutes — the BMS uses a trickle recovery phase to bring the cell back above the threshold before resuming normal charging. If the shear still won't respond after that window, the cell has likely dropped below the point of safe recovery and needs replacement.
