Description

The Accu 2.2 is an external battery backup for Sommer evo+ and pro+ openers, with far more reserve than the internal Accu: up to 36 hours on standby or 75 door cycles on a charge, so a power outage does not shut the car in the garage.

Performance varies with operating conditions, and the pack mounts outside the opener.
