For those who have ordered from Olike know the battery and charger is shipped separate. Much slower I was told, the glasses I ordered on Friday are already on a plane. With no tracking number will assume it could be weeks until I see it. I was wondering if there is an alternate battery Ni Cad or alkaline that can be used temporarily to replace the "Ultra Fire BRC 18650 3.7V 300ma", they (Susie), Only informed me of the separate shipment after the transaction cleared and already had a tracking number. Had I known would have opted to drive into the city, and picked up a set from one of the hundred stores that sell special order batteries. Obviously I'm not doing that now. Only complaint about Olike thus far.
