The zinc air battery is powered by air; if it doesnt get enough air in through the vent holes before use, it will not work properly. We ask that you remove the tab and wait a minute or so to give the air a chance to get into the battery. It will then power right up and youll get great service. We have seen some issues in the past where the consumer did not let the battery power up and we saw premature failure or dead cells. If a customer does see dead cells, tell them to wait a minute once they peel the tab off. This should solve the problem.
