I have a rather strange problem. I have a PCB assembled circuit with a 18650 Li-Ion battery and a TP4056A battery charger IC with a USB Type C socket. When I place the battery in the battery holder and switch the circuit ON it simply doesn’t work. The battery (NCR18650B) is full but it still doesn’t work, and I’ve tried with several batteries of the same kind. Nonetheless, once I plug a charger with USB Type C to the circuit and unplug it (so as to charge the battery), even for a second, then, after switching the circuit ON, it works solely on battery with the charger removed.
Why is this happening ?
Hope someone could help me. Thank you in advance !
