Array Controller Batteries Caution Removing an array controller battery may cause data loss. The battery supplies power to the DIMMs on the array controller card. To prevent data loss, you must either ensure the array is in a dual array controller configuration, or you must perform an array shutdown. If the array is in a dual array controller configuration, it is recommended that you replace both array controller batteries. The array controller battery is a Lithium ion type. When removed, the battery must be recycled or disposed of properly. Replace the battery only with the same type. Shelf life for the array controller battery is rated for up to 6 months at a maximum temperature of 25º C. If this storage temperature or duration is exceeded, it may be necessary to recharge the battery during normal operation of the controller.
