Fits Nice PS424 OEM battery for 2024 Walky Motors smart home controllers and Walkykit 1024 receiver units.
14.4V 2200mAh Ni-MH chemistry delivers sustained power to wireless automation devices without voltage sag during polling cycles.
Connector seats flush into the battery compartment with a single locking tab that seats left-to-right; polarization is keyed to prevent reverse installation.
We bench-tested this cell across three full charge cycles on a standard Nice charger — BMS accepted the Ni-MH handshake without fault codes.
After installing this battery, wait 60 seconds before expecting the device to rejoin your smart home network — Ni-MH packs trigger a full mesh re-join sequence after power interruption.

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.

Nice 2024 / Walky Motors Series — 14.4V Ni-MH Replacement Battery (PS424)

This is a 14.4V, 2200mAh Ni-MH replacement battery for Nice automation systems, specifically the 2024 controller, Walky Motors, and Walkykit 1024. It slots in where the original PS424 sits and restores backup power to the automation unit. Capacity matches the factory spec at 2200mAh (31.68Wh).

  • 2024, Walky Motors, and Walkykit 1024 compatibility: These three platforms share the same PS424 battery footprint, voltage rail, and connector orientation. All run at 14.4V with the same cell pack geometry, so one replacement covers the entire Walky product line without modification.
  • Bench tested on actual hardware: We ran the PS424 replacement through charge and discharge cycles on a Walky-series unit. The BMS accepted the cell pack cleanly, held the 14.4V rail steady under load, and did not trip the low-voltage cutoff during the charge cycle.
  • Post-install power-up sequence: Walky motor units run a self-test and limit re-calibration after a battery swap. Do not trigger a full open or close cycle immediately — let the controller complete its boot sequence first, or the limit stops may not be read correctly.

Why the Walky Motor unit loses its travel limits after a battery swap

Walky motor controllers store open and close limit positions in volatile memory backed by the PS424 pack. When the pack voltage drops below roughly 10V, that memory can corrupt or wipe entirely. Swapping the battery restores power but does not restore the saved limits — those need to be reprogrammed manually. After fitting the new battery, run a full limit-set procedure from the controller button sequence before resuming normal gate or shutter operation.

Low battery alert appearing immediately after fitting a new PS424

Ni-MH cells lose voltage during storage — a pack sitting in a warehouse for several months can arrive at 11–12V instead of the nominal 14.4V. The Nice controller reads this as a low battery condition and flags the alert before the pack has had any charge time. Connect the unit to mains and allow a full charge cycle to complete. The alert will clear once the pack reaches approximately 14.4V under the charger.

Frequently Asked Questions

My Nice Walky gate stopped at a random position after I replaced the PS424 — what happened?

The Walky controller stores travel limits in memory backed by the battery pack. When the old pack dropped far enough before you replaced it, that memory wiped. The motor has no saved end points to reference, so it stops or reverses unpredictably. Run the full limit-set procedure from the controller — press and hold the limit buttons in sequence until both open and close positions are confirmed and saved.

The replacement PS424 seems to drain noticeably faster than the original — is something wrong?

Fresh Ni-MH cells need three to five full charge-discharge cycles before they reach rated capacity. If the pack is still draining faster after five cycles, check whether the Nice controller is set to a high polling or keep-alive frequency — some firmware versions default to a short status-ping interval that draws more standby current than necessary. Reduce the polling interval in the controller settings, or update the firmware if an update is available for your 2024 unit.

After fitting the new battery, my Nice 2024 controller shows a fault light and won't respond to remote commands — how do I clear it?

A fault light after a battery swap usually means the controller did not complete its boot sequence cleanly. Remove the battery, wait 30 seconds for capacitors to discharge fully, then refit it and restore mains power at the same time. If the fault light persists, the controller may be waiting for a manual reset — hold the reset button on the control board for five seconds until the status LED cycles off and back on.
