About this replacement
Wella Eclipse Clipper — 3.7V Li-ion Replacement Battery (8725-1001)
This is a 3.7V, 3000mAh (11.1Wh) lithium-ion battery for the Wella Eclipse Clipper. It replaces OEM part numbers 8725-1001 and 93151-101. If your Eclipse Clipper no longer holds a charge or cuts out during use, this is the direct cell replacement.
- Eclipse Clipper platform fit: The Eclipse Clipper uses a single-cell 3.7V Li-ion configuration with a specific cell footprint of 65.81 × 20.60 × 18.40mm. The BMS handshake and connector pinout match the OEM spec — no modifications needed to seat and connect the cell.
- Bench tested on actual hardware: We ran this cell through charge cycles on the Eclipse Clipper platform and confirmed the BMS accepted the cell without triggering a protection fault. Motor load draw stayed within the cell's discharge curve through full depletion.
- Clipper port care after cleaning: If you rinse or wipe down the Eclipse Clipper with product spray, let the charging port air dry for at least 30 minutes before docking. Residual moisture bridging the charge contacts trips a BMS protection fault the device reads as a dead battery — not a charging error.
Why the Eclipse Clipper loses cutting power before the low-battery indicator activates
The Eclipse Clipper's motor draws a sharp current spike under load — especially through thick or coarse hair. A degraded cell cannot hold voltage steady under that spike, so voltage sags below the motor's operating threshold before the fuel gauge registers empty. The indicator measures resting voltage between cuts, not voltage under load. A fresh 3000mAh cell with a lower internal resistance closes that gap and maintains consistent motor speed through the discharge cycle.
Capacity indicator drifts after months of daily partial charging
Charging the Eclipse Clipper daily without fully depleting the cell causes the BMS's state-of-charge estimate to drift. The indicator shows full, but the clipper cuts out well before the session ends. This is not a dock or charger fault — it is a cell calibration issue compounded by shallow-cycle degradation. Replace the cell, then run two full discharge-and-charge cycles to let the BMS recalibrate against the new cell's actual capacity.
