SUA750rm2u with RBC22 or RBC24 Battery

[Anonymous user]

I've got a SUA750rm2u, in a phone rack. Power is running about 35% of design. The RBC22 battery tray only has two batteries. I notice the RBC24 (which is for the SUA1500rm2u) is the exact same tray dimensions with 4 batteries, but still at the same 24 volts.

Can I pick up one of those and get about double my run time??

No it would not because the SUA750RM2U was not designed to function with an RBC24 and the battery charger of the SUA750RM2U won't be able to handle the charging.
