Fridge backup is an interesting application of the battery, though it does negate one of the advantages - not having to do any wiring if you’re only set up for gas with a regular 120v outlet.
Our current range is Dual Fuel so I'm good to go. [smile]

I would imagine that a new 240V line would cost less than replacing the battery when it goes dead.
On the other hand, I would have preferred my garage door operator to have been battery operated. That way, when there is a power outage my garage door would still open and close. At most, it would need to operate the door 4 or 6 times. Power outages in my area are rarely longer than 12 hours.
I'd be curious about the replacement cost for a new battery. My neighbor has a Tesla and they want $15K to $20K for a complete battery replacement. [eek]
My garage door opener has battery back-up and LiftMaster says the battery has enough capacity to cycle the garage door opener 6-8 times for an 18' wide steel door.
I thought the garage door opener
always operated on batteries, and the line voltage was just to recharge the battery.
I didn’t think that battery was a backup. I thought it was primary.
That's not how my Liftmaster/chamberlain works, to my knowledge. The unit runs noticeably and significantly slower on battery than on line voltage.
It saved our bacon in 2020 after a major storm left us without power for 13 days to allow us to get our vehicles out, but definitely died after the listed "6-8 times".
My Craftsman garage door operators (two doors, two operators) can be manually opened and closed by first pulling on an overhead cord that disconnects the door from the chain drive, and then lifting manually.
If the electricity is out, then I have to go through the front door and (usually) negotiate through the dark house to where I keep my flashlight. Then out to the garage and manually open the door and then manually close it.
The real burden is when the electricity comes back on. The unit is often reluctant to reconnect to the chain drive.
On a side note, we all acknowledge that the electric garage door opener is a great convenience. Less often noted is the security and safety advantage of the remote operation.
Your wife or your daughter gets home late. The house is dark. She gets out of the car to open the door and some bad guy is hiding in the bushes.
Or…
Your wife or your daughter gets home late. The house is dark. She pushes the remote button and the garage door opens and the garage is lit up. Her car is locked. She drives into the garage, shuts off the engine and pushed the remote to close the door. The bad guy is still in the bushes.
I would note that the wife or daughter should close the door while still in the locked car using the remote. Then exit the car and enter the house. (This applies to houses with garages attached to the house.). Most modern cars automatically lock the doors as you drive off. So a real safety benefit.
This is not being paranoid; it is simply best practices. No extra work; just a prescribed procedure.
You live in a good neighborhood? Why break into a rundown, low value house? A upscale house is going to have more valuables to steal.
