Today I was so excited for my MIDI to come with the energy pack. I am just starting my Festool collection. I fully charged both batteries (both had 3 green lights when completed the charging) and then signed into the app on my phone to register the batteries. I had to add each separately as there is software updates to install. All went well for the first one, but the second one had an error, and now every time I push the green button the blue lights blinks for quite awhile until it stops. The battery will now not even charge and the charger light is red. I never expected to get a battery like this from a company that has such expensive tools. Customer service will be sending me another battery but I can't work this weekend like I had planned. Anyone else have this experience? Was this just an anomaly?
