6.1

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).
If the UPS requires any type of transportation, verify that the UPS is disconnected and turned off
and then disconnect the UPS internal battery connector (see figure 28 on page 28).
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.
6.2

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 internal batteries charge to 90 % capacity in less than 3 hours. However, Eaton
recommends that the batteries charge for 48 hours after long-term storage. If optional EBMs are
installed, see the recharge times listed in table 24 on page 33.
Check the battery recharge date on the shipping carton label. If the date has passed and the batteries
were never recharged, do not use the UPS. Contact your service representative.
6.3

When to Replace Batteries

When the
displays, the batteries may need replacing. Contact your service representative to order new batteries.
6.4

Replacing Batteries

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 "UPS Shutdown" on page 18.
Consider all warnings, cautions, and notes before replacing batteries.
