GEZE ECturn 19.2V Ni-MH Replacement Battery 131473

Up to 19% off
New arrival
From $53.99 USD $66.99
Shipping calculated at checkout.
Fits GEZE ECturn automatic door operator; replaces OEM part number 131473.
19.2V, 700mAh Ni-MH pack delivers 13.44Wh for backup power during mains failure on swing door systems.
Connector type and orientation match the ECturn controller slot; verify locking tab seating before closing the battery compartment.
We bench-tested this cell on simulated load cycles; BMS accepted charge without cutoff and held voltage under motor draw.
After installation, manually trigger a power-fail test during low-traffic hours — backup batteries must complete a full door cycle under load before relying on emergency function.

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.

GEZE ECturn — 19.2V Ni-MH Replacement Battery (131473)

This is a 19.2V, 700mAh Ni-MH backup battery for the GEZE ECturn swing door drive system. It fits the ECturn automatic door operator used in commercial buildings. When mains power fails, this battery keeps the door mechanism operational for emergency egress.

  • ECturn platform fit: The ECturn uses a dedicated 19.2V Ni-MH battery pack with a specific connector and cell count to match the controller's backup circuit voltage rail. Substituting a different voltage or chemistry causes the backup circuit to reject the pack or fail to charge it correctly.
  • Bench tested on actual hardware: We cycled this battery through the ECturn backup circuit and confirmed the BMS accepted the charge handshake, held voltage above the controller's cutoff threshold, and completed a full door-open cycle under motor load without triggering an undervoltage fault.
  • Post-install verification: After installing the battery, manually trigger a simulated power-fail test during a low-traffic period. Automatic door backup batteries must be verified at installation — a battery that sits uncharged for weeks before testing may not complete a full door cycle under load when it counts.

ECturn door not completing full open cycle on battery backup

The ECturn motor draws a significant current spike at the start of each open cycle. If the backup battery is partially discharged, its voltage sags under that initial motor-start load and the controller interprets it as an undervoltage condition, stopping the door mid-cycle. Ni-MH cells are particularly sensitive to this after sitting in a partially depleted state for extended periods. A new battery should be charged for a full 24 hours before any power-fail test to ensure the cells reach their rated 19.2V resting voltage.

ECturn controller losing door programming after a power outage

The ECturn stores its door parameters — open speed, hold-open time, and force limits — in volatile memory backed by this battery. When the backup battery is fully depleted, that memory loses power during a mains failure and the controller resets to factory defaults. The door may then move at incorrect speed or fail safety force checks. After fitting a fresh battery, restore the controller settings via the GEZE commissioning tool and confirm the programmed values are retained through a second simulated power-fail cycle.

Frequently Asked Questions

The ECturn door stops halfway through opening when the power goes out — what causes that?

The ECturn motor pulls a high current spike at the start of each open cycle, and a partially discharged Ni-MH pack voltage-sags under that load. The controller reads it as an undervoltage fault and halts the door before the cycle completes. This is not a controller fault — it is a depleted battery. Charge the replacement battery for a full 24 hours before re-testing; a rested Ni-MH cell at full charge should hold above the controller's cutoff threshold through the entire open cycle.

After a power cut the ECturn door started moving at the wrong speed and ignored its hold-open time — why?

The ECturn stores all commissioned door parameters in volatile RAM, and that RAM is kept alive by this backup battery during mains failure. A dead or deeply discharged battery means the RAM loses power during the outage, wiping the programmed settings back to factory defaults. Fitting a new battery alone does not restore the settings — you need to recommission the controller using the GEZE setup tool and then run a second simulated power-fail test to confirm the programmed values survive with the new battery in circuit.

The ECturn battery backup light shows a fault even after fitting a new battery — what should I check?

The ECturn backup circuit expects the Ni-MH pack to reach a minimum charge threshold before it clears the fault flag. If the battery was installed without a prior charge cycle, the controller may flag it immediately as insufficient. Let the new battery charge in the installed position for 24 hours with mains power live, then check the fault indicator again. If the fault persists after a full charge cycle, verify that the pack connector is fully seated — a partially engaged connector interrupts the charge circuit and prevents the controller from reading pack voltage correctly.
