Tondeo ECO X Profi 2.4V Ni-MH Compatible Battery 2000mAh

Tondeo ECO X Profi / ECO-X — 2.4V Ni-MH Replacement Battery

This is a 2.4V 2000mAh Ni-MH replacement battery for the Tondeo ECO X Profi and ECO-X professional hair clippers. These cordless clippers are used in barbershops and salons, where a degraded battery causes the motor to lose speed mid-cut. This battery restores full motor drive voltage across the complete discharge cycle.

• ECO X Profi and ECO-X compatibility: Both models run the same 2.4V motor rail and share the same battery housing dimensions (48.73 × 28.68 × 14.31mm). The BMS on each model expects the same charge termination profile, so a single Ni-MH cell pack fits both without modification.
• Bench tested on actual hardware: We ran this pack through full charge-discharge cycles and confirmed the BMS accepted charge termination correctly. Voltage held steady through the mid-discharge range, with cutoff triggering cleanly at the low-voltage threshold rather than dropping the motor abruptly.
• Salon cycle care: Clippers in daily professional use are often put on charge between clients rather than run to depletion. Ni-MH chemistry handles this better than Li-ion, but a full discharge-to-cutoff cycle every two to three weeks keeps the pack's voltage curve calibrated with the fuel gauge.

Capacity fade from daily partial charging on the ECO X Profi

Ni-MH cells develop a soft memory effect when repeatedly charged from 60–80% capacity rather than from a depleted state. In a busy salon, the clipper rarely runs flat before going back on the dock. Over several months, the pack's usable voltage window narrows, and the motor starts losing torque earlier in the charge cycle even though the indicator still shows charge remaining. Running the clipper fully to cutoff before recharging — every two to three weeks — prevents this voltage depression from becoming permanent.

Motor speed dropping before the low-battery indicator activates

The ECO X Profi's motor pulls a higher current spike during thick or dense cuts. A battery with degraded cells cannot sustain voltage under that load, so the motor slows noticeably before the BMS reaches its cutoff threshold. The indicator light does not reflect this sag — it reads average cell voltage, not voltage under load. If the clipper bogs down mid-cut but the indicator still shows charge, the battery is no longer holding voltage under draw. Replacing the pack and running a full conditioning cycle resolves this immediately.
