C&D MsEndur II Series: The Pinnacle of Standby Power Reliability

The C&D MsEndur II Series represents a significant advancement in Valve-Regulated Lead-Acid (VRLA) battery technology, specifically engineered for critical standby power applications. These batteries seamlessly blend the extended service life characteristic of flooded batteries with the high-performance energy density of VRLA batteries, establishing a new benchmark for reliability and total cost of ownership in the UPS and battery backup market.

Unparalleled Performance and Longevity

The MsEndur II Series is meticulously designed for a 20-year operational life, providing long-term, trouble-free service. This exceptional longevity is achieved through the use of a proprietary patented lead-calcium-tin-silver positive-plate alloy, which minimizes grid corrosion and growth. The series boasts a high-recombination efficiency, eliminating the need for periodic water additions and reducing maintenance requirements. Its robust design is validated for demanding environments, meeting stringent NEBS and UBC seismic standards.

Core Features at a Glance:

• Extended Service Life: A 20-year design life in float service at 25°C ensures long-term reliability and reduces the frequency of replacements.
• Enhanced Safety: The batteries feature a self-resealing, flame-arresting vent (UL 924) that prevents oxygen ingress and ensures safe operation. The container and cover are crafted from flame-retardant, high-strength thermoplastic.
• High Energy Density: The series offers a high power output in a compact footprint, optimizing space utilization in equipment rooms.
• Maintenance-Free Operation: As a VRLA battery, the MsEndur II Series is maintenance-free, requiring no water additions throughout its operational life.
• Robust Construction: Designed to withstand the rigors of transportation and handling, the series is classified as "Non-Spillable" by DOT, IATA, and ICAO.
• Seismic and NEBS Compliance: The MsEndur II Series is certified to meet NEBS Level 3 and UBC Seismic Zone 4 requirements, making it suitable for deployment in critical infrastructure.
• Ohmic Ring® Technology: This innovative feature allows for quick and easy measurements of the internal ohmic values, simplifying maintenance procedures.
