Thanks for coming back on this. It looks like if i stick with the lead acid, I cannot just use one string, but need both, so 32 batteries. I cannot find online whether I can put in cheaper 12V 7.2ah batteries instead of 9ah. I just need it to deliver 1kW for 15 minutes occasionally before it's...
Hi guys, I'm sitting with this problem now.
I have a Eaton UPS with 32 9ah VRLA batteries. It takes 2 strings of 16.
9 Ah sealed, valve-regulated lead acid (VRLA), maintenance-free, minimum 3-year float service
life at 25°C (77°F), voltage 192 Vdc (96 cells per string)...
