Review on ⚡️ Efficient TOPAC 3.5/7A 6/12 Volt Automatic Car Battery Charger: Ideal for Automotive, Motorcycle, Boat & Marine, RV, Toys, Power Tools, Lawn & Garden Battery Systems by Logan Goozmer

I bought this unit to keep a group 27 battery charged for my gate opener. Works well, easy to set up. However, since installing it I've had 3 instances where the unit has reset to 6v instead of 12v (probably after a power outage) which I only discovered after the battery had drained to the point where the gate automatically opened . I will be remapping this charger and replacing it with a 12V only unit.
