Does Arris NVG589 Gateway Backup Battery Need to be Replaced?
While reconfiguring my home office, I powered down my AT&T U-verse Gateway, Arris NVH589. Once I powered the router back up, I noticed the battery light was blinking. However, after 10-20 minutes it stopped. Does the backup battery need to be replaced? If so, what is the Motorolla P/N for the replacement battery and where may one be purchsed?
