About this replacement
AL-KO Multicutter / Grass Shear — 7.4V Li-ion Replacement Battery
This 7.4V, 2000mAh Li-ion battery fits the AL-KO Multicutter GS 7.2 Li grass and shrub shear line. The GS 7.2 Li is a cordless multi-tool used for trimming grass edges and light hedging. Rated at 14.8Wh, this pack matches the original voltage rail and connector the tool expects.
- Compatibility across GS 7.2 Li variants: The Multicutter GS 7.2 Li, Strauchschere GS 7.2 Li, and related 113 371 units share the same 7.4V battery bay, connector orientation, and BMS handshake, so one pack covers the range.
- Bench tested on actual hardware: We ran full charge/discharge cycles on this pack — the BMS held voltage steady under cutting load and tripped cleanly at the low-voltage cutoff without requiring a manual reset.
- First charge after storage: If the pack arrives in storage mode, run a full charge before the first use — Li-ion cells shipped partially charged can read low on the tool's indicator until the BMS calibrates to a complete cycle.
Why voltage accuracy matters in a 7.4V shear tool
The GS 7.2 Li motor controller is tuned to a narrow voltage window. A pack that delivers even half a volt over spec stresses the FETs in the tool's drive circuit. At exactly 7.4V nominal, the motor runs at the torque curve AL-KO set for the blade assembly, which keeps the cutting action consistent across both the grass and shrub blade attachments.
Tool stops cutting mid-use — what's happening and how to fix it
If the GS 7.2 Li cuts out suddenly during use rather than slowing gradually, the BMS has triggered an overcurrent cutoff — usually caused by blade binding or a jammed cutting head forcing a current spike. Remove the blade attachment, clear any debris, and reattach before restarting. If the tool won't restart immediately, remove the battery, wait 30 seconds for the BMS to reset, then reinsert and try again.
