Purchased 4 12v / 9AH batteries, 2 12v / 6.5 AH batteries and a couple of NIcad 3.7v / 2000 mah battery packs to replace the backup batteries of 3 UPS units and 2 emergency light packs. Shipping was quick, batteries were a good physical fit to the old batteries and they all work. Price was well below what I found elsewhere.
