Hello,   There is no command.  Once the new battery is installed it should reset itself.  Doesn't sound like a new battery is my guess.   You can get standard support for 7 years after ship date or Post Standard Support for 12 years.  Both now include firmware updates for array and drives.    Just something to consider.   Regards, Don
