Nickel cadmium batteries in UPS design features

Abstract

The author presents design features and service experience gained which indicate why the nickel-cadmium pocket plate battery is a viable alternative to lead-acid batteries in UPS (uninterruptible power supply) systems where reliable standby power is essential. Laboratory testing indicates that nickel-cadmium pocket plate batteries are not influenced by the unique voltage conditions in UPS systems. Field experience from a large number of installations confirms these results. Cost considerations are also reviewed.<>
