Thanks for the help. Got the batteries revived

I have 2 ninebot mini pros that have not been turned on in about a 6 months. They are stored in our house. Neither one will turn on at all now. I plugged the battery charger in and the light on the charger pack stayed green. Left plugged in overnight just in case, but still will not turn on this morning. Any ideas to correct this issue are greatly appreciated
