Battery replacement guidelines
If you have to replace the UPS internal battery, make sure that you replace both
internal battery modules and also replace the connected extended battery module
at the same time. Replacing these batteries at the same time avoids internal
damage to the UPS and the battery modules.
Notes:
1. The internal battery module CRU contains only one battery module. Make sure
that you order two each of CRU part number 81Y2315.
2. The extended battery module CRU comes without the front bezel.
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 batteries every 6 months by
connecting the UPS to a power source. The batteries charge to 90% capacity in
approximately 8 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.
Note: The UPS can be charged with or without load. The charging can occur with
the UPS connected to a power outlet (it automatically goes to Standby mode) and
not turned on.
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).
