That guy.

APC RBC43

RBC43 Batteries are compatible with the following APC UPS's DLA3000RM2U, DLA3000RMT2U, SUA2200RM2U, SUA2200RMUS, SUA3000RM2U, SUA3000RMT2U , SUA3000RMUS , SUM1500RMXL2U, SUM3000RMXL2U

I unwrapped the plastic wrap around it, but the battery has literally not been removed from the shipping box.
