How to recycle old laptop battery into power bank | DIY | Arun

This video shows you how to make power bank from used/old laptop battery. The li-ion 18650 battery cells present in laptop battery are connected in parallel and then connected with battery charging board. Here I made 8000mah power bank from four 18650 battery cells. NOTE: *Check all the cells with multimeter, a good cell should contain 3.7V.. In my video, I already checked those cells with multimeter. Since those rusty two dead cells contains 0V, so I ignored those cells. Other four cells contains approximately contains 3.7V while checking* By recycling the old batteries, we can reduce the electronic wastes. It's simple and you can do it yourself.
