Poor design that needs work before use
on October 13, 2013
My garage door has a battery with a F1 negative and a F2 positive. If I had to do over I would never have purchased the adapter as the F2 terminal fit the F1 battery terminal without any problems with a tight fit.
If you look at the photo you will see there is a tit on the adapter that goes in the slot in the battery terminal. The tit is useless and makes it extremely hard to install the adapter. Once installed the adapter moves all around as it has a very loose fit and the slot in the batter terminal is very large compared to the tit.
I wound up flattening the tit and squeezing the clips on the adapter so that it now has a tight fit and is easy to install.
