before you connect the new battery. This duration is the minimum amount of time that is needed for the
card to recognize that the battery has been replaced.
Note: The battery is a lithium ion battery. 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.
Attention: To prevent data loss, if the cache battery pack is not already in the error state, follow the
steps described in Forcing a rechargeable battery error before proceeding. If the cache data present LED is
flashing, do not replace the cache battery pack or data will be lost. See the feature descriptions and the
figures in the following sections to determine if your adapter has a cache data present LED and the
location of the LED.
