The SMU-HR series of Valve Regulated Lead Acid (VRLA) batteries is designed to meet the needs
of many industrial and utility applications. The success of the AlphaCell SMU-HR series is due to a
product design purpose-built for the needs of critical backup requirements, and an industry-leading
manufacturing technology which delivers product consistency. Safety, reliability, and long service life
in standby applications are the result.
Alpha offers a full line of racking solutions to accommodate the SMU-HR series of batteries. SMU-HR
batteries provide easy terminal access for installation and maintenance, and can be upright-, side-, or
end-mounted. The SMU-HR series includes eight models to make it easier to install and maintain the
batteries.
1.1 Features
Require no additional water throughout their life cycle, reducing maintenance costs. •
Specifically designed to meet the requirements of modern electronic equipment. •
Compatible with commonly available recharging systems. •
Compact construction and excellent performance at high rates of discharge provide big •
savings in volume and weight compared to conventional vented batteries.
SMU-HR batteries offer substantial savings in installation and maintenance costs •
compared to conventional vented batteries. No specifically designed rooms are required
and only minimal maintenance is needed during the life of the battery.
SMU-HR batteries are very easy to maneuver. Smaller, more compact, and lighter than •
traditional batteries, SMU-HR batteries are supplied filled and charged so they can be
immediately installed directly into cabinets or on easily assembled racks (also available
from AlphaCell).
With a minimum 10 year design life, the SMU-HR batteries are highly reliable and fully •
comply with established international standards. The SMU-HR range has been fully
tested with respect to charge and discharge characteristics, cycle life, recombination
efficiency, mechanical strength, vibration life, and flame retardancy.
