Mighty Max Battery 6volt 7.2ah Battery Replacement for WKA6-7.2F - 4 Pack

Seems to do the trick. Only time will tell, but we're back and running with fire exit emergency lights for now! Great price too!UPDATE: Got 3 years out of this. Please don't review something until you have truly given it a "test drive". I got 5 years out of the D***cell brand. Done with this brand.

The price is right and fast shipping, exactly as described and they work well.
