I was recently given 40 of the batteries. They just came out of service.
It wasn't time to replace them yet but a new much larger power back up system was installed.
They all measure somewhere between 12.6v - 12.72v. I have the wheeled racks they go in also. Even the racks weigh 100 LBs each.
They were configured as 240 volts per rack. My RE system is 48 volt, so I'm relocating them in my shop.
Brand is DATA SAFE By ENERSYS INC. Mod # NPX-150R specs 12v, 150W/CEL 15 MIN.
They measure 7.75" wide X 6.75" tall X 6.5" deep and weigh 31 LBs each.
I picked these up in my E-Truck. 10 miles to town, pick up 1500 LBS of batteries and 10 miles home. Not a hitch. E-truck works great. Even thought about putting these in the E-truck but Nah, I need them in the RE system.
The question is, how many amp hours are these batteries? I did a load test after 1 hr charging on one to 13.6 volts. With my carbon pile 500 amp load tester I got 220 amps at 10 volts and 125 amps at 11 volts. I figure even if there good for 50 AH that should add 500 ah at 48 volts to my RE system?
Heres the pictures.
