Genio 1565 Shaver Compatible Battery 1.2V 1800mAh Ni-MH

Genio 1565 / 1574 Series — 1.2V Ni-MH Replacement Battery

This is a 1.2V, 1800mAh Ni-MH replacement battery for Genio electric shavers including the 1565, 1565A, 1565B, and 1574 models. It fits the original battery bay directly and matches the voltage and chemistry the shaver's charging circuit expects. When the original cell degrades and the shaver dies mid-use or won't hold charge, this replaces it.

• 1565 and 1574 series compatibility: These models share the same single-cell Ni-MH voltage rail at 1.2V and the same cylindrical cell format — 49.90 × 14.30 × 14.30mm. That shared spec is why one cell covers the whole model range.
• Bench tested on actual hardware: We ran this cell through charge and discharge cycles on the shaver platform and confirmed the protection circuit accepted the full charge without fault. Discharge behaviour under motor load matched factory cell performance.
• Wet shaver port care: If the shaver is rinsed after use, let the charging port air dry fully before docking — even a thin film of water bridging the charge contacts can trigger a protection fault the device shows as a dead battery rather than a charging error.

Capacity fade from daily partial charging on the Genio 1565

Ni-MH cells in shavers degrade faster when they are charged daily without being fully depleted. This shallow-cycle pattern means the cell never reaches a full discharge, and over time the charge indicator drifts out of sync with actual remaining capacity. The shaver may show charge remaining but cut out under motor load. Replacing the cell resets this — but avoid topping up after every shave. Let the cell run down to low indicator before charging.

Shaver motor speed dropping before the low-battery indicator activates

This happens because the motor draws a current spike during shaving that the cell can't sustain at low state of charge, even if the indicator hasn't flagged empty yet. Voltage sags under load before the BMS cutoff threshold is reached, so the motor slows but the shaver stays on. It's a cell condition issue, not a motor fault. A fresh cell holds voltage through the load spike — check that the replacement cell reads at least 1.2V off the charger before fitting.
