Calling Florida Power and Light, told me I am caller number 475, please wait patiently, and my cell phone had 30% battery left, with no way to recharge. 

I replaced the batteries at the controller near the bedroom and it worked.

This is only a 4-plex but the CE officer told me that the big complexes will send someone through a few days before to change the smoke detector batteries and make sure they work but by the time the inspector comes, 25% have been removed by the tenants. 

They battery went out on the garage remote and they told me the garage door was broken. 

Have you checked the batteries ?

At the same time , not only does the 90 day challenge put a battery in my back, but a mentor falls out of the sky.

It's true that Battery Park and Barton Heights are dramatically improving.

By not motorizing the extension and retraction of the deadbolt, battery life is much longer and you do not need to worry about the deadbolt sticking if the door and jamb are a little out of alignment as the building shifts with the seasons.We've had some of these locks in-place for 5+ years.

Some with extra features may require batteries.

1) standardize to one battery type for your power tools 2) impact driver 3) fluke multimeter
