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).
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.

If you store the UPS for a long period, recharge the battery every six months by connecting the UPS to utility
power. The batteries charge to 80% capacity in fewer than five 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 DO NOT DISCONNECT the batteries while the UPS is in Battery mode.
Batteries can be replaced easily without turning the UPS off or disconnecting the load.
If you prefer to remove input power to change the batteries, see section 5.12“Individual Paralleled UPS
Shutdown.
Consider all warnings, cautions, and notes before replacing batteries.
