A friend's company is changing out a bunch of large ups batteries and I have access to basically whatever I can use of the old ones. They are Northstar NSB-12-730RT Pure lead batteries that have been in an industrial online UPS for about a year. Online UPSes are dual conversion, where grid power charges the batteries and an inverter generates AC from the batteries. It is not standby mode. This means the batteries have been in constant use, albeit not heavily discharged, for the past year. These are 62kg a piece and hold about 190ah.
I have seen Northstar AGM batteries mentioned favourably on this list before, but not this specific model. What are your thoughts / opinions?
