Battery Backup for the AC41 Door Controller

Learn how to use a backup battery on your Verkada AC41 Door Controller

Verkada door controllers bring plug-and-play simplicity to enterprise-grade access control. The Verkada AC41 Door Controller supports existing door hardware and card readers while enabling cloud-based access to a limitless number of doors and events across your organization.

Verkada offers the ACC-BAT-4AH for use with the AC41, where it can be powered by a 12V 4.5Ah, sealed lead-acid (SLA) battery as a backup power source.

Install a backup battery to your AC41

In case of a power outage, or situations where your Verkada Access Controller is powering locks, or being used in critical safety applications, we strongly recommend that you to consider a battery backup plan.

Connect the red lead with the positive (+) connector on the battery and the black one to the negative (-). The battery pack can then sit inside the Verkada AC41 case.

Wire backup batteries to the AC41

To get double the amp hours (capacity), while maintaining the same voltage, you can connect 2 batteries in parallel (not in series) to provide twice as much battery capacity.
