⚠️⚠️⚠️NOTE REGARDING 1.5V LI-ION BATTERIES:

This charger does not support modern 1.5V constant-voltage lithium batteries. Due to the specific design of these cells and the safety systems built into the charger (which include a voltage-range lockout between 1.65V and 1.85V), they require dedicated chargers provided by the manufacturer.
