About this replacement
Gardena ComfortCut Grass Shears — 7.4V Li-ion Replacement Battery
This listing is for a 7.4V 1500mAh Li-ion replacement battery pack for the Gardena ComfortCut series of cordless grass shears. These shears handle lawn edge trimming and boxwood shaping using an 8 cm dual-blade system. The original pack is a 2S1P Li-ion configuration, and this replacement matches that cell arrangement, voltage rail, and physical footprint at 66.40 x 36.40 x 20.40mm.
- Compatibility across ComfortCut models: The ComfortCut 8893 and 8895 share the same 7.4V battery platform and connector, so one pack covers both units without adapter changes.
- Bench tested on actual hardware: We ran full charge and discharge cycles — the BMS held voltage steady under blade load and triggered the low-voltage cutoff cleanly without a hard drop.
- First charge after storage: Li-ion cells shipped in a partial state of charge should be fully charged before first use — this lets the BMS calibrate its state-of-charge tracking from a known baseline.
Why 2S1P cell configuration matters in compact shear batteries
A 2S1P arrangement places two Li-ion cells in series to reach the 7.4V nominal voltage the ComfortCut motor requires. The BMS monitors each cell independently for overvoltage and undervoltage conditions. This matters in a tool that sees short, repeated duty cycles — the kind of stop-start use that unevenly stresses individual cells over time.
Shears power up but cut weakly — likely a voltage sag issue
Weak cutting force with a charged battery usually means the pack can't sustain voltage once blade resistance kicks in. This is a sign of degraded cells losing capacity under load, not a motor fault. Swap to a fresh pack first before diagnosing the drive mechanism. If cut strength returns immediately, the original battery is the cause.
