The environmental conditions of their UPS system are the primary concern for a battery system. Unfavorable environments can considerably decrease the service life available. The capacity of batteries to conduct and store energy is adversely affected by batteries that are too hot or too cold. It is estimated that the battery life is halved by each 8-10 ° C increase in temperature. Refer to the requirements of the manufacturer of the Batterie per UPS ( Batteries for UPS) for the required battery range of temperature.
In addition, making sure that the batteries are properly charged is also important. The specifications for the battery manufacturer will include a float voltage specification. This value can be specified for either the battery block’s full voltage or the volt-per-cell level. To handle line losses between the UPS and the battery strings, it is vital to ensure that the battery float is balanced as calculated at the input to the battery string.
The float voltage should be balanced in such a way that the batteries can be loaded into the published battery range within the string. Battery downloads can reduce battery life and may pose a danger to their facility or workers over charging batteries. It is recommended that they visually check each batteries at least once a year. Any inflammation or corrosion might display a premature failure-causing adverse condition. It is also necessary to look at the battery cabinet or rack itself if the battery blocks are visually inspected. Any electrical leakage will flow to the cabinet itself of the battery. The battery rack/cabinet may become corrosive or short-circuit, which could jeopardize ones vital strength and/or employees.
