Lighting Battery for Lithonia D-AA650BX4 Exit Sign - Squared

Working great after 1 week, October 2016. Had to release latches on contact pins to reverse the polarity of the connector for our exact application, but that's child's play; no wire cutting required. There is probably a video out there to show you how to do that easily if you don't know already.I will try to update this if they either fail or survive for a few years.

I wonder why the the Polarity is different than need be , had to cut the and switch polarity , so watch out. no harm done but i was high up on a ladder to see this , come down the ladder , sit down cut wires , solder back together , insulate connection, where for my money i wish i could just plug it in and forget it. At my age is hard to go up high on a ladder !!!

The item arrived as promised. We haven't used it yet, but it appears to be what we needed.

I've seen two different battery wire configurations, check the wire position before you install it. Mine was right, I checked another unit in my shop and it was the opposite. It's a manufacturer thing, not the battery. Battery plugged in and worked fine.

Glad that we wereable to save the emergency exit signs with a simple battery exchange.

I got these batteries to replace it with the emergency light unit that we have at work and I was glad to find it here. It works great and it fits like the original one.

Worked like a charm on my apartment hallway ceiling exit lights. Recommended.
