About this replacement
Wahl 7060 / 9020 / 9326 / 9816 Series — 1.2V Ni-MH Replacement Battery (00745-301)
This is a 1.2V, 2000mAh Ni-MH replacement battery for the Wahl 7060 cordless shaver and compatible models including the 9020, 9326, and 9816. It replaces OEM part 00745-301 when the original cell has degraded and no longer holds a usable charge. The battery fits inside the shaver housing and powers the cutting head motor directly.
- 7060 / 9020 / 9326 / 9816 compatibility: These models share the same single-cell Ni-MH format, voltage rail, and connector footprint. The physical cell dimensions — 37.40 x 22.30 x 22.30mm — match the OEM spec, so the battery seats correctly without modification.
- Bench tested on actual hardware: We ran this cell through charge and discharge cycles on the 7060 platform. The BMS accepted the cell without fault flags, and the motor drew current within the expected range across the full discharge curve.
- Port drying before charge: Wahl shavers used near water need a fully dry charging port before docking. Moisture bridging the charging contacts triggers a protection fault the device reports as a dead battery — not a charging error. Dry the port with a cloth and wait two minutes before connecting.
Capacity fade from daily partial charging on the Wahl 7060
Ni-MH cells in shavers used daily develop voltage depression when recharged before the cell is meaningfully depleted. The shaver's charge indicator drifts because it reads terminal voltage, not true state of charge. Over time the usable window narrows — the shaver appears fully charged but cuts out early under motor load. Running the cell to low charge before each full charge cycle resets this pattern and restores accurate indicator behaviour.
Motor speed dropping before the charge indicator reaches empty
The 7060 cutting head motor draws a current spike on startup that a degraded cell cannot sustain without voltage sag. The indicator may still show partial charge, but the cell's internal resistance has risen enough that motor load pulls the voltage below the operating threshold. The shaver slows or stalls while the indicator reads mid-charge. Replacing the cell resolves this — the indicator and actual performance realign once the new cell's internal resistance is within spec.
