I am now attempting to charge my second Verso rechargeable light. First one the battery would not charge. After 16 hours on charge, arm would not swing out, light would not come on.Exchange light #2 after charging all afternoon,and till 10pm no light, arm would not swing out. With charger plugged in arm would swing around and light would come on. Unplug the charger, light goes out. The light is useless.
