How to Revive a Dead Lithium Battery | 2 Simple Methods to Recharge It

Hello everyone! In today's video, I will share with you 2 simple ways to recharge (reactivate) dead lithium batteries, helping to reuse old or non-rechargeable batteries. These are methods that I have tried and found effective with 3.7V batteries commonly used in phones, tablets, electric vehicles, and other electronic devices.

Method 1: Using 1S (3.7V) Circuit with Low Charging Current

In this method, we use a 1S protection circuit (protection circuit for 3.7V batteries) combined with a low charging current from 0.1A to 0.2A to recharge dead lithium batteries. This circuit will help you charge the battery safely without damaging the battery or causing danger.

Method 2: Parallel Connection With Low Voltage Battery

In case your battery is completely dead, you can connect it in parallel with another battery with a low voltage from 3V to 3.3V. This method helps to "activate" the dead battery by using a good battery to recharge the damaged battery.

Remember to watch the video to know the details of each step, as well as important notes when performing these methods! If you find the video useful, don't forget to like, share and subscribe to the channel to see more great tips on technology and device repair.
