The SMU-C series of Valve Regulated Lead Acid (VRLA) batteries is designed to meet the needs of
modern electronic equipment. The success of the AlphaCell SMU-C 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.
1.1 Features
Require no additional water throughout their life cycle, reducing maintenance costs. •
Specically 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-C batteries offer substantial savings in installation and maintenance costs •
compared to conventional vented batteries. No specically designed rooms are required
and only minimal maintenance is needed during the life of the battery.
Smaller, more compact, and lighter than traditional batteries, SMU-C batteries are •
supplied lled and charged so they can be immediately installed directly into cabinets or
on easily assembled racks (also available from Alpha).
With a minimum 10 year design life, the SMU-C batteries are highly reliable and fully •
comply with established international standards. The SMU-C range has been fully tested
with respect to charge and discharge characteristics, cycle life, recombination efciency,
mechanical strength, vibration life, and ame retardancy.
