There is a good one on amazon here: http://www.amazon.com/Liftmaster-485LM-Battery-Backup-Opener/dp/B001T3WHZ8. You can also try googling a replacement battery and find various other places and comparitive shop, however beware of places that are selling them very cheap or that you have never heard of because they may not be safe to purchase from. Good luck!
