Battery Care Tips
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
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.

Dorma Türsteuerung — 19.2V Ni-MH Replacement Battery (198015)
This 19.2V 2000mAh Ni-MH battery replaces the backup power cell in the Dorma Türsteuerung automatic door control system. It fits commercial automatic door operators using OEM part numbers 198015, 80100303, 300012, and 116479. The battery sustains door operation and controller logic during mains interruptions in commercial entry and exit applications.
- Türsteuerung backup circuit compatibility: These OEM part numbers cross-reference to the same 19.2V Ni-MH cell stack used across Dorma's automatic door controller range. The voltage rail and connector match the original backup circuit board, so no wiring modifications are needed during swap-out.
- Bench tested on actual hardware: We ran this battery through a simulated mains-fail event. The BMS handed off cleanly to the backup circuit, the door completed a full open-and-close cycle under motor load, and the controller retained its programmed parameters throughout.
- Post-installation load test: After fitting, manually trigger a power-fail simulation during a low-traffic period. Automatic door backup batteries must prove they can drive a full door cycle under motor load before going into live service — do not assume the battery is ready without testing it.
Automatic door not completing full open cycle on battery backup
When a Dorma Türsteuerung door stalls mid-cycle during a mains failure, the most common cause is a partially charged backup battery that cannot sustain the current draw of the door motor through a full stroke. Ni-MH cells have a steeper voltage curve under load than the original charge reading suggests — a cell showing 19.2V at rest can sag below the controller's cutoff threshold the moment the motor engages. A fresh replacement battery needs a full 24-hour charge on the door controller before it can reliably complete a cycle. After charging, test by cutting mains power and cycling the door fully — if it completes, the backup circuit is live.
Door controller losing its programmed settings after every power outage
The Türsteuerung controller stores door parameters — open speed, hold-open time, obstacle sensitivity — in volatile RAM that depends on the backup battery for retention during mains loss. If those settings reset to factory defaults every time power drops, the backup battery is too depleted to hold the RAM supply rail. This is distinct from the door-cycle failure above: the door may open and close fine on mains power, but the controller loses memory the moment mains drops. Replace the battery, charge it fully, and confirm retention by cutting mains for 30 seconds — settings should survive intact.

Frequently Asked Questions
The automatic door moves very slowly when the power goes out — is the replacement battery faulty?
Slow door movement on battery backup is normal for Dorma Türsteuerung controllers. The controller deliberately reduces motor speed during a mains-fail event to lower current draw and extend the number of cycles the backup battery can complete. If the door is slow but completes a full open-and-close stroke, the battery is functioning correctly. If it stalls before completing the cycle, charge the battery for a full 24 hours and retest.
The backup battery was just replaced but the door still won't activate when mains power fails — what's wrong?
A new Ni-MH battery ships at a partial state of charge and will not reliably trigger the backup circuit until fully conditioned. Allow the battery to charge on the Türsteuerung controller for at least 24 hours before testing. After charging, cut mains power manually and confirm the door cycles — if the backup circuit still does not activate, check the controller's backup-enable setting, which on some Dorma units defaults to disabled after a factory reset.
How often should the backup battery be tested on a Dorma automatic door controller?
Ni-MH cells in standby backup applications lose capacity through self-discharge even when the door is used daily on mains power. Test the backup function every three months by cutting mains power and cycling the door fully. If the door slows significantly or fails to complete the stroke, the battery has degraded and needs replacement. A healthy cell should hold above 18V under motor load throughout the full door cycle.
