About this replacement
Wella Eclipse Clipper — 3.7V Li-ion Replacement Battery (8725-1001)
This 3.7V, 2200mAh Li-ion cell replaces the OEM battery in the Wella Eclipse Clipper cordless hair clipper. It restores full cordless cutting power for barbers and stylists when the original pack degrades. Capacity is 8.14Wh — matched to the stock specification.
- Eclipse Clipper platform fit: The Eclipse Clipper runs a single-cell 3.7V Li-ion architecture with a BMS that monitors cell voltage and temperature. This replacement matches the OEM voltage rail and connector footprint so the clipper's charge indicator and protection circuits communicate correctly with the pack.
- Bench tested on actual hardware: We cycled this cell through full charge and discharge passes on the Eclipse Clipper platform. The BMS accepted charge handshake without fault, and cutoff triggered at the correct low-voltage threshold without dropping into protection lock.
- Motor load tip for daily salon use: Heavy continuous passes through thick hair spike current draw sharply. Let the clipper cool for two to three minutes between extended cutting sessions — sustained high-draw use without a break accelerates cell temperature and can trigger the BMS thermal cutoff before the battery indicator shows low.
Why the Eclipse Clipper loses blade speed before the battery indicator shows empty
The Eclipse Clipper's indicator reads state of charge from a resting voltage estimate, not under load. When the motor pulls peak current — during thick or dense hair passes — cell voltage sags below what the resting estimate predicts. The BMS registers this sag and reduces output to protect the cell, which the user experiences as blade slowdown even though the indicator still shows charge remaining. A worn or partially degraded cell sags harder under the same load, making this symptom appear earlier in the charge cycle.
Eclipse Clipper not charging after cleaning product exposure
Spray disinfectants and clipper coolants used in salon environments can leave residue on the charging contacts. Moisture or chemical film bridging the contacts causes the BMS to trip a protection fault — the device reports a dead or unresponsive battery when the actual fault is at the contact interface. Wipe both the clipper charging port and the charger pins with a dry cloth before reconnecting. If charge still does not initiate, allow the contacts to dry fully for 30 minutes, then reconnect — the BMS should re-initialise and accept charge above 2.5V cell voltage.
