Emergency Lighting Mounted on Ceiling?

[Dan Cullen]

In the hallways of a recently constructed mid-rise condominium building I found the battery back-up emergency lighting was installed on the ceiling. What is normally the back of the emergency lighting fixture was secured to the ceiling. Wouldn't this put the battery in an inappropriate position and perhaps lead to the battery electrolyte leaking? Thoughts? Thanks!

Batteries used in such units are normally sealed batteries and have no proper orientation.

Much obliged!

You can search online with the model number and see what the manual says about installation orientation.

If you have the newer LED units, the battery is not a "dry cell" but MiCd, Ni metal Hydryde, etc. Sorry for the "spelling".

They last much longer that the old dry cells and are much lighter.

Until LED units came about, most batteries for these units for the past 40+ years were sealed lead acid batteries.
