The batteries compatible with the Automatic Sanitiser are 4 x standard C size. Approximately 30,000 shots per battery loadout to help minimise the amount of workload for your team. Just like refilling, they are super easy to change. Just unlock the door and pull the door down to a 90-degree angle, remove the battery cover and replace depleted batteries, replace the battery cover and close the door. Now you’re ready to power up! Note: Batteries not included.
