Storing the UPS and batteries
If you store the UPS for a long period, recharge the batteries every 6 months by
connecting the UPS to a power source. The batteries charge to 90% capacity in
approximately 3 hours. However, you should charge the batteries for 48 hours after
long-term storage. Check the battery recharge date on the shipping carton label. If
the expiration date has passed and the batteries were never recharged, do not use
the UPS. Contact your technical-support representative.
Replacing the battery modules (for qualified personnel only)
CAUTION:
Lead-acid batteries can present a risk of electrical burn from high,
short-circuit current. Avoid battery contact with metal materials; remove
watches, rings, or other metal objects, and use tools with insulated handles.
To avoid possible explosion, do not burn.
Exchange only with the IBM-approved part. Recycle or discard the battery as
instructed by local regulations. In the United States, IBM has a process for
the collection of this battery. For information, call 1-800-426-4333. Have the
IBM part number for the battery unit available when you call. (C004)
Servicing of batteries must be performed or supervised by personnel who are
knowledgeable about batteries and the required precautions. Keep unauthorized
personnel away from batteries. Batteries can present a risk of electrical shock or
burn from high short-circuit current.
Determine whether the battery is inadvertently grounded. If it is inadvertently
grounded, remove the utility source from the ground. Contact with any part of a
grounded battery can result in electrical shock. The likelihood of such shock can be
reduced if such grounds are removed during installation and maintenance
(applicable to equipment and remote battery supplies that do not have a grounded
supply circuit).
Replace batteries with the same number and type of batteries as originally installed
in the UPS. Do not dispose of batteries in a fire. Batteries might explode when
exposed to flame.
Do not open or mutilate the batteries. Released electrolyte is harmful to the skin
and eyes and can be extremely toxic.
The 11000 VA UPS might have an extended battery module option.
If the message Service Battery is displayed and the audible alarm is on
continuously, you might have to replace the battery module. Contact your
technical-support representative to order new batteries.
Important: Do not disconnect the batteries while the UPS is in Battery mode.
Consider all warnings, cautions, and notes before you replace batteries. Disconnect
the charging source before you connect or disconnect the battery terminals.
