About this replacement
Record Saga Easy — 24V Ni-MH Replacement Battery (MGN0609 / 246-6438)
This 24V, 2000mAh Ni-MH battery replaces the backup power cell in the Record Saga Easy automatic door operator. It maintains power to the electronic control system during mains failure, allowing the door to complete open and close cycles without interruption. Fits the Saga Easy platform as a direct voltage and form-factor match at 142.00 × 49.40 × 28.60mm.
- Saga Easy controller compatibility: The Saga Easy uses a dedicated 24V backup rail that the control board monitors continuously. This battery matches that rail voltage and the connector orientation the Saga Easy expects — a mismatch here prevents the backup circuit from arming at all.
- Bench tested on actual hardware: We ran this battery through a simulated mains-fail event on the Saga Easy controller. The BMS held voltage above the low-battery cutoff threshold throughout a full open-and-close cycle under load, and the controller returned correct status flags throughout.
- Post-installation activation check: After fitting, manually trigger a power-fail test during a low-traffic period. Backup batteries in automatic door systems must complete at least one full door cycle under load at installation — this confirms the battery is charged and the backup circuit has armed correctly.
Automatic door not completing full open cycle on battery backup
When mains power drops, the Saga Easy controller draws current from the backup battery to drive the door motor through its full travel. A degraded or partially charged Ni-MH cell will sag below the controller's minimum operating voltage mid-cycle, causing the door to stall or reverse before reaching end-stop. This is not a controller fault — it is a battery voltage issue. Charge the new battery for a full 24 hours before running a power-fail test, then confirm open-cycle voltage stays above 22V under motor load.
Controller losing door programming after a power outage
The Saga Easy stores configuration — open speed, hold-open time, obstacle sensitivity — in volatile memory backed by this battery. If the battery has discharged deeply enough, that memory loses its supply during a mains outage and the controller resets to factory defaults. The door will still move after power returns, but its programmed behaviour will be gone. Replacing the backup battery and reloading the configuration via the controller's setup procedure resolves this — do not re-program until the new battery has completed a full charge cycle.
