Where do i find the back up battery

Look at the manual it has a list of part numbers, I ordered from amazon

What is the maximum height door in which this cohld open?

Residential go for 10 ft Commercial go for 14 ft

Why is this one almost $200 more than other places for the same part number?

I believe this is a kit that comes with lots of options including the optional locks and safety eyes
