Imagine that you have 2 celular phones, you know they have different chargers, suddenly your favorite celular phone charger
explodes, dissapear or even if you connect your charger to your favorite phone, the phone says is not charging your battery is diying! and you NEED to use your fav phone because it haves the photos, videos etc that you want to share or is just that
YOU NEED TO USE YOUR FAV PHONE IN THAT MOMENT AND YOU CANT BUY A NEW PHONE CHARGER AT THAT MOMENT
or maybe you just want to charge a 3.6 volt batteries from disposed celularphones.
here is how:
you will need:
2 cell phones
1 working cell charger
1 rubber band
1 male header pin with 3 pins
Also you cant use the charger directly because cellphone companies loves to make you buy a special cellphone chargers with weird connectors.
Open both cellphones and remove the batteries, check that both batteries haves the same voltage, in this case 3.6 v, also check the polarity of each battery, double check the polarity of both batteries with a multimeter IS VERY IMPORTANT!
If you did everything right, then you can check if your battery is charging by turning on the phone, if the cellphone works fine, then you are charging your battery, if the phone dont turns on then you did something wrong or the pins are not connected right.
Give it 2 or 3 hours so the battery can get full charge, the celphone will tell you when the battery is at full charge.
dont overcharge even if the cellphone haves protection for the battery, just dont tempt your luck
NEVER LET THE BATTERIES WITHOUT SUPERVISION, YOU HAVE TO WATCH OVER THE BATTERIES JUST IN CASE SOMETHING GOES WRONG, IF YOU HAVE TO DO SOMETHING AND YOU CANT CHECK THE BATTERIES THEN DISCONECT ALL THE COMPONENTS AND DO IT WHEN YOU HAVE TIME TO WATCH THE BATTERIES.
I TAKE NO RESPONSABILITY FOR ANY DAMAGE, IS YOUR RESPONSABILITY IF YOU WANT TO TRY THIS INSTRUCTABLE.
