hifistud, this is very strange these batteries like this, all are protected with pcb and prevent short circuit and overcharge.
We are sorry for this trouble, please send all batteries and chargers back too us , for testing by manufacturer.
Please send customer service with tracking number for a full refund.
Kind Regards
