Charging Recycled Li-ion Batteries Answered
I have busted mp3 players that I've already thrown away but decided to keep the Li-ion batteries in them for future use. Now i tried to connect them to LED's to turn into flashlights and they worked perfectly. Now the main concern is if i will use them as batteries for my flashlight how will i be able to charge them?
Can I replace the jacks of the mp3 players' original charger with bulldog clips and just connect them to the terminals of the Li-ion batteries to charge them or do i need to connect a simple circuit for the Li-ion batteries?
