ETA 1423900000 Replacement Battery 9.6V 2000mAh Ni-MH

Up to 19% off
New arrival
From $49.99 USD $61.99
Shipping calculated at checkout.
Fits ETA model 1423900000 and 1423 Verto II cordless vacuums; replaces OEM battery 142300100.
9.6V Ni-MH chemistry with 2000mAh capacity delivers stable voltage under motor load on carpet and hard floors.
Connector seats vertically into the handle dock with a positive-lead orientation; locking tab engages on insertion and release.
We bench-tested this cell on a 1423 motor stage — BMS held steady under sustained suction draw with no early cutoff.
Do not leave the vacuum on the charging dock continuously after the battery reaches full charge; trickle charge degrades Ni-MH capacity faster than charge-and-remove cycles.

Battery Care Tips

🔹 Getting Started

Charge your new battery fully before you use it for the first time. Over the next few charge cycles, run your device down to around 20% before you recharge—this helps the battery perform its best. After that, charge whenever you need to.

🔹 Keep It Healthy

Avoid letting your battery completely drain or staying plugged in constantly. Both extremes wear it out faster. Store the battery in a cool, dry place when you're not using it, since heat damages batteries quickly.

Delivery and Shipping

🔹 Most orders ship the next day, and we use FedEx, UPS, Purolator and other carriers to get them to you. Lithium batteries have to ship by ground only, not air or USPS. Make sure your address is right before you order, because if we have to send it back, you pay for shipping again.

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.

Frequently Asked Questions

My ETA 1423 Verto II had noticeably shorter run time after a few months — is the replacement battery going to do the same thing?

Capacity fade on the original pack was almost certainly caused by continuous dock charging. The ETA 1423 dock does not cut power when the battery is full, so Ni-MH cells absorb trickle current for hours or days at a time, which degrades them faster than normal charge cycles. With the replacement, charge fully and remove the vacuum from the dock rather than leaving it sitting there. That alone extends usable capacity significantly over time.

The replacement battery charges but the vacuum suction is noticeably weaker than I expected — what's wrong?

Weak suction on a freshly charged pack usually points to a blocked filter, not the battery. A restricted filter forces the motor to work harder, drawing more current and causing voltage sag, which drops motor speed and suction output before the pack is anywhere near depleted. Remove and clean the filter, then retest. If suction improves, the battery was fine all along. If suction stays weak with a clean filter, check that pack voltage under load holds above 8.4V — if it sags below that, the cells are underperforming.

The ETA 1423 motor suddenly stopped mid-use, then started working again on its own — is the battery defective?

That stop-and-restart pattern is a BMS overcurrent trip, not a dead battery. It happens when the motor hits a restriction — a blockage in the nozzle, hose, or a clogged filter — and current draw spikes past the pack's protection threshold. The BMS cuts the circuit for a few seconds, then resets. Check the nozzle and hose for blockages and confirm the filter is clean before concluding the battery is at fault. If the motor keeps tripping on a fully clear vacuum, measure pack voltage at rest — it should read at or above 9.6V on a full charge.
