rechargeable battery

Overview

For a long time, every time the dry battery of the remote control or wireless mouse ran out, I felt extremely unhappy when I thought about using 10 AA batteries in a year and forgetting to buy them. I also made a DIY AA battery to contribute to the cause of environmental protection. 1.5V rechargeable lithium battery, TP4054 charges the 3.7V 135mAh lithium battery with a charging current of about 100mA, M3406 DC-DC reduces the lithium battery voltage to 1.5V, XB3303 protects the lithium battery from overcharge, overdischarge and overcurrent, specially selected for low power consumption Chip M3406, 3.7V, standby current 25uA, 135mAh lithium battery can standby for 225 days, the structure is so-so and it can be used.
