12 V 7.5 Ah SLA UPS Battery

This 12 volt 7.5 ampere-hour sealed lead-acid battery uses advanced AGM technology to provide maintenance-free backup power for compatible uninterruptible power supplies. It arrives new and ready to install without electrolyte handling. The design matches the original form factor for direct replacement in supported units.

Replaces RBC110 RBC2 and OEM equivalents

The battery replaces APC RBC110 and RBC2 cartridges as well as Powersonic PS-12120, CSB GP12120, Panasonic LC-RA1212P, Yuasa NP12-12 and other listed cross-reference models. The upgrade is worthwhile when the existing pack no longer holds charge or has reached the end of its expected 4 to 7 year service life. Swapping the pack restores full runtime without replacing the entire UPS.

T1/T2 terminal interface limits

The T1/T2 terminal pair restricts use to UPS units designed for this specific connector spacing and polarity. It cannot be used in devices requiring bolt-on lugs, threaded studs or proprietary quick-disconnect plugs. The physical dimensions of 5.94 by 2.56 by 3.66 inches further constrain fitment to battery compartments sized for this footprint.
