Keep critical infrastructure protected with a replacement battery built for supported CyberPower UPS systems. The RBC55-CP uses a 2 x 12 V 17 Ah lead-acid configuration to help preserve runtime, stabilize backup performance, and extend the service life of your power protection investment. For IT teams managing uptime-sensitive environments, a battery cartridge replacement is often the most cost-effective way to restore UPS performance without changing the entire unit. This pack is designed for maintenance windows, refresh cycles, and aging battery replacement where consistent backup power matters more than a full system swap. At 53.6 lb, it reflects the substantial battery capacity required for enterprise-class backup support. Use it to return a compatible UPS to service with less disruption and more predictable runtime behavior. When power quality is non-negotiable, replacing the battery on schedule helps protect servers, network gear, storage, and edge systems from avoidable downtime.
