About this replacement
Wolf Garten Cordless Grass Shear & Shrub Shear — 7.2V Ni-MH Replacement Battery
This listing covers the 7.2V, 3000mAh Ni-MH replacement battery for the Wolf Garten cordless grass shear and shrub shear range. It matches the 7099-056 part number and fits the 7.2V battery platform shared across the GH60, GX-M, and GS40 models. Capacity is 3000mAh, delivering 21.6Wh — identical to the original specification.
- GH60, GX-M, and GS40 compatibility: All three models draw from the same 7.2V rail and use the same connector and BMS handshake, so one battery pack covers the full trio.
- Bench tested on actual hardware: We ran full charge/discharge cycles — the BMS held voltage steady under the light, intermittent load typical of shear blades and released cleanly at the low-voltage cutoff without tripping the tool's protection circuit.
- First charge after storage: Ni-MH cells that have been sitting lose charge memory faster than lithium. Run two to three full charge/discharge cycles before judging capacity — performance improves noticeably after conditioning.
Why Ni-MH still makes sense for low-draw shear tools
Grass shears and shrub shears draw short, intermittent bursts of current rather than sustained high loads. Ni-MH chemistry handles that pattern well without the thermal sensitivity lithium packs carry. The 3000mAh capacity is a meaningful step up from older 1500–2000mAh packs in the same physical footprint. Storage below 50% charge in a cool, dry location extends cell lifespan significantly.
Shear powers on but cuts weakly — what's happening and how to fix it
Weak cutting force on the GH60 or GS40 usually points to voltage sag from a degraded or deeply discharged cell rather than a blade problem. When individual Ni-MH cells drop out of balance, the pack can show a surface charge but collapses under load. Charge the replacement pack fully before first use, then run it down completely — this balancing cycle resets the cell matching. If the symptom persists after conditioning, the issue is mechanical, not electrical.
