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 25°C (77°F).

Storing the UPS and Batteries

If you store the UPS for a long period, recharge the battery every 6 months by connecting the UPS to utility
power. The batteries charge to 80% capacity in fewer than 5 hours. However, Eaton recommends that the
batteries charge for 48 hours after long-term storage.
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.

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.
