I have a lot of 9-volt batteries that are discharged.I didn't have a specific charger to charge them, so after thinking for a long time, I came up with an idea: let's make a line-volt charger at home.Then I took all my tools and built a line bolt battery charger.And this charger usually operates with a mobile charger, meaning that a 9-volt battery can be charged with a mobile charger.To boost this charger, I first took a TP4056 module and connected a voltage booster to its back.I set the voltage booster to ten volts and installed a small display to see what voltage we had.Finally, I charged a nine-volt battery and it is fully charged and I can easily charge my remaining batteries with this charger.If you like the video, be sure to give it a like and subscribe to the channel.
