I own a EGO twist vv battery and recently it's been refusing to charge. Before I put the battery on the light on my charger shows its working, but about halfway through screwing it on, the light turns off and it stops working. I tried to raise the center piece on both my battery and charger and the same thing kept up. The strange part is, I found if I push the button on my battery while it's plugged in the light on my charger will turn on and it'll start to work until I let go of the button. Any help would be greatly appreciated
