Red flashing lights on one of the batteries?

[SwiftyNI]

Still haven't received my replacement Anafi ( Yikes! My Anafi now lives at the bottom of a lake... ) so I've been using my friend's Anafi when I discovered one of their batteries is flashing red it's LEDs and not functioning in the drone. The drone has been barely used (4-5 flights). They said they haven't been using because of this since they have 2 more spares so thought I might as well try and find a solution for him! Any ideas?

Connect battery to charger,press and hold power button on battery for 12seconds,let go of power button,let it charge for few hours ,install battery in anafi and see if its working

This is part of the Anafi battery being smart! It goes into a hibernation type of mode after not being used for 12 days & then needs to be plugged in to a charger to reawaken it.
