Bartschneider EP50 Replacement Battery 1.2V 1800mAh

Bartschneider EP50 / EP60 / EP80 / EP100 Series — 1.2V Ni-MH Replacement Battery

This is a 1.2V 1800mAh Ni-MH replacement cell for Bartschneider shavers including the EP50, EP60, EP80, and EP100. It replaces the original internal battery when the shaver no longer holds charge or the motor noticeably loses speed before the indicator shows empty. Capacity matches the original at 1800mAh (2.16Wh).

• EP50 / EP60 / EP80 / EP100 compatibility: These models share a common 1.2V single-cell Ni-MH architecture and the same physical cell format — 49.90 × 14.30 × 14.30mm. The motor drive circuit draws directly from this cell without a separate voltage regulator, so cell voltage and capacity must stay within the original spec or motor performance suffers immediately.
• Bench tested on actual hardware: We cycled this cell through load conditions matching the EP50 motor draw. The cell held stable voltage through multiple discharge cycles with no thermal events, and the charge termination responded correctly to the shaver's delta-V cutoff circuit.
• Post-rinse charging on waterproof models: If your shaver is rinsed under the tap, dry the charging port and housing seams fully before docking. Moisture bridging the charge contacts triggers a protection fault the shaver reports as a dead battery — not a charging error. A dry cloth and 20 minutes of air time clears it.

Motor speed dropping before the indicator reaches empty

Ni-MH cells in shavers age through voltage sag — the resting voltage stays acceptable, but the cell can no longer sustain voltage under the motor's load current. The shaver's indicator reads remaining charge from resting voltage, not under-load voltage, so it shows 30–40% remaining while the motor is already starved. You feel this as a drop in cutting speed or a change in motor pitch before any low-battery warning appears. Replacing the cell restores full under-load voltage delivery and motor speed across the full discharge cycle.

Capacity fade from daily partial charging on the shaver

Ni-MH cells degrade faster when repeatedly charged from a shallow state — common in shavers that sit on a dock every night regardless of charge level. This creates a soft memory-like effect where the cell's usable capacity shrinks to match the shallow cycle window. The shaver appears fully charged but cuts out far earlier than expected. Running the cell to full depletion before a complete charge cycle at least once a week slows this drift.
