That UPS in your server room is running on a battery that's past its prime. You've probably noticed the runtime shrinking, or the self-test flagging a weak cell. This is the 48V cartridge your SMX unit was built to take. Four sealed lead-acid blocks in one enclosed cartridge — plug it in and you're back to full protection. No disassembly, no guessing at voltages. Arrives with all connectors, an installation guide, and a recycling sheet. Three to five years of dependable backup ahead of you. 2-year warranty included. Compatible with SMX1500RMI2U, SMX1500RMI2UNC, SMX48RMBP2U, and SMX48RMBP2US. Add to cart while the old battery still holds a charge
