THE EFFECTS OF EXTREME TEMPERATURES ON BATTERIES

NOVA’S RUGGED GALAXY-SERIES RACK-MOUNT UPS SYSTEMS HAVE AN OPERATING TEMPERATURE RANGE OF –20 TO +50 DEGREES CELSIUS, WHILE THE STORAGE TEMPERATURE LIMIT IS –40 TO +60 DEGREES CELSIUS. HOWEVER, USERS SHOULD BE ADVISED THAT HIGH TEMPERATURES POSE A SIGNIFICANT PROBLEM FOR THE BATTERIES USED IN (OR WITH) NOVA ELECTRIC (OR ANY OTHER BRAND) UPS SYSTEM SYSTEMS. EVEN THOUGH THE STANDARD SEALED, MAINTENANCE FREE BATTERIES USED WITH NOVA UPS SYSTEMS ARE RATED FOR USE UP TO 50 DEGREES CELSIUS, HIGH TEMPERATURES SERVE TO DECREASE THE OVERALL BATTERY LIFE EXPECTANCY. SPECIFICALLY, AT 50 DEGREES CELSIUS, THE BATTERIES WILL SELF-DISCHARGE AT A RATE OF UP TO APPROXIMATELY 0.75% PER DAY. FURTHER, LIFE EXPECTANCY OF THE BATTERIES USED AT 50-60 DEGREES CELSIUS IS REDUCED TO THE RANGE OF 9-18 MONTHS, AS OPPOSED TO A LIFE EXPECTANCY OF 3-5 YEARS FOR BATTERIES USED IN THE IDEAL AVERAGE OPERATING TEMPERATURE OF 25 DEGREES CELSIUS. CONVERSELY, LOW OPERATING TEMPERATURES OF -20 DEGREES CELSIUS AND BELOW SIGNIFICANTLY REDUCE RUN-TIME FROM THE RATED AMOUNT TO ALMOST ZERO! IF LOW TEMPERATURES ARE PART OF YOUR APPLICATION, PLEASE BE SURE TO COMPENSATE FOR THE REDUCED RUN TIME BY INCREASING THE RATING OF YOUR BATTERY SYSTEM – CONSULT THE FACTORY FOR DETAILS. FOR MORE INFORMATION, BATTERY CHARACTERISTIC CHARTS ARE AVAILABLE UPON REQUEST FROM THE FACTORY SO THAT USERS CAN SEE THE NEGATIVE EFFECTS OF PROLONGED EXPOSURE TO EXTREME TEMPERATURES ON BATTERY LIFE IN MORE DETAIL.

PLEASE NOTE THAT ON CERTAIN UPS SYSTEMS, WE ALSO OFFER PREMIUM HAWKER ENERGY BATTERIES. THESE SPECIALIZED, SUPER-RUGGED BATTERIES ARE LESS SENSITIVE TO TEMPERATURE FLUCTUATIONS THAN THE STANDARD BATTERIES, AND ARE ALSO MUCH MORE RESISTANT TO SEVER SHOCK AND VIBRATION APPLICATIONS. THESE BATTERIES ALSO HAVE IMPROVED WEIGHT / RUN TIME RATIOS FOR SHORT RUN TIME APPLICATIONS. PLEASE CONSULT THE FACTORY FOR FURTHER DETAILS.
