What are the advantages of using the VDC instead of lead-acid batteries?
When compared to the traditional lead-acid battery in UPS application the VDC has the following advantages: • Reliability – Up to a 20x higher reliability than a single string of VRLA (Valve Regulated Lead Acid) batteries that are typically used in UPS applications. • Predictable availability – The flywheel energy storage availability and status is always known with its built in monitoring and reporting system, unlike a battery system which requires a very expensive add-on monitoring system. Even then the state of availability is only really known once the battery is called upon to be used. • Longer Life – The VDC has over a 20 year expected life and run time performance never degrades during that period. VRLA batteries are typically replaced every 4 years and run time performance degrades with age and usage. The VDC can perform thousands of discharges and the run time on the last discharge will be the same as the run time on the first. • Reduction of Required Maintenance – The VDC req
