The battery maintains the blade configuration, date, and time information in the NVRAM when the blade is turned off. You may need to replace the battery if an incorrect time or date is displayed during the boot routine.
You can operate the blade without a battery; however, the blade configuration information maintained by the battery in NVRAM is erased each time you remove power from the blade. Therefore, you must re-enter the system configuration information and reset the options each time the blade boots until you replace the battery.
