First, we should charge it and then we can get output after connection.

 Please do not mix the good battery and poor battery to use. The internal resistance of 3 battery capacity is closer will be better. Please, buyers, know the professional knowledge of this module before buying.

 Please don’t mix the good battery and bad battery because it gives different values on different qualities of batteries.
