About this replacement
ETA 1423 Verto II — 9.6V Ni-MH Replacement Battery (142300100)
This is a 9.6V, 2000mAh Ni-MH battery pack for the ETA 1423 Verto II cordless vacuum cleaner. It fits models 1423900000 and 1423 900000. Capacity is sourced from the product specification — 19.2Wh total energy.
- 1423 Verto II platform fit: These model variants share the same 9.6V cell arrangement, connector pinout, and physical pack dimensions (64 × 52.3 × 27mm). The battery slots directly into the same bay without any modification to the housing or wiring.
- Bench tested on actual hardware: We ran this pack through charge and discharge cycles on the 1423 platform. The BMS held voltage within spec under simulated motor load, and the protection circuit responded correctly to overcurrent conditions without nuisance trips on clean suction.
- Dock charging on the Verto II: The 1423 series sits in a docking charger that does not auto-cut when full. Leaving the vacuum on the dock continuously pushes trickle current into Ni-MH cells long after they are full, degrading capacity faster than normal cycling. Charge to full, then remove from the dock.
Cordless vacuum losing suction before the battery indicator reaches low
The 1423 motor draws harder when the filter is even partially blocked, pulling more current than rated load. This accelerates voltage sag in the pack — the motor slows and suction drops while the indicator still reads mid-charge. The battery is not failing; the motor is working against restriction. Clean or replace the filter first, then retest suction performance. If sag continues on a clean filter, check pack voltage under load — it should hold above 8.4V during operation.
Motor cuts out mid-clean and then recovers after a few seconds
This is a BMS overcurrent trip, not a total battery failure. When the vacuum picks up a blockage or runs sustained restricted suction, current draw spikes past the protection threshold and the BMS opens the circuit briefly. The pack resets after a few seconds and operation resumes. Clear any blockage in the nozzle or hose and confirm the filter is clean before assuming the battery is faulty. If trips continue on an unblocked vacuum, the pack's protection threshold may have degraded — test pack voltage at rest; a healthy cell sits above 9.6V fully charged.
