UPS and Battery Care
For the best preventive maintenance, keep the area around the UPS clean and dust–free. If the atmosphere is
very dusty, clean the outside of the system with a vacuum cleaner.
For full battery life, keep the UPS at an ambient temperature of 77°F (25°C).
Note: The batteries in the UPS are rated for a 3–5 year service life. The length of service life varies,
depending on the frequency of usage and ambient temperature. Batteries used beyond expected
service life will often have severely reduced runtimes. Replace batteries at least every 5 years to keep
units running at peak efficiency.
Storing the UPS and Batteries
When storing the UPS and optional cabinets, the following requirements should be met:
l
Verify that the battery circuit breaker is in the OFF position.
l
Avoid temperature and humidity extremes. To maximize battery life, the recommended storage temperature
is 59°F (15°C) to 77°F (25°C).
l
If you store the UPS for a long period, recharge the batteries every 10 months by applying utility power. The
batteries charge to 80% capacity in approximately 3 hours. However, it is recommended that the batteries
charge for 48 hours after long-term storage.
l
Check the battery recharge date on the shipping carton label. If the date has expired and the batteries were
never recharged, do not use the UPS. Contact your service representative.
When to Replace Batteries
When the indicator flashes and the LCD panel displays Battery Failure, the batteries may need replacing.
Contact your service representative to order new batteries.
Change the batteries approximately every five years.
Recycling the Used Battery or UPS
Contact your local recycling or hazardous waste center for information on proper disposal of the used battery
or UPS.
