Introduction: Trick to Start Your Non-working Mobile Battries.

About: I am crazy electronics engineer.... "I love to take things apart to see what's inside. I want to understand how things work. I've been doing that since I was a little kid..." "I don't love math. It's the basis…

Can you through your mobile battery if it’s not working or charging.

Here is a simple trick to mak works your mobile battery .For this you have to make simple 12 V power circuit which gives your sleeping or uncharged mobile batteries a 12 voltage shock to charge your battery.

Step 1: Follow the Steps:

1. Remove battery from mobile.
2. Clean the surface of contact of batteries.
3. Connect the output of circuit to your mobile battery (as shown in picture) only for 20-30 sec not more than that.
4. Connect positive terminal of circuit to positive terminal of battery & negative terminal of circuit to negative terminal of battery.
5. Then connect your battery to again to your mobile, your mobile will start. Still it shows warning that “low battery”.
6. Now you can connect your normal battery charger to mobile for charging.
7. Your mobile battery is now working.

This trick can be used for following condition of batteries:

1. If your battery should be in good condition.
2. If battery should not be wearied out.

Step 2: To Make This Circuit You Required Following Things:

• Four 1N4001 diodes
• LM7812 regulator
• 230-15v step down Transformer
• 2200uF capacitor
• 0.1uF capacitor
• Jumper wires (I used some plain wire as jumper wires)
• Heatsink (optional)

Make the circuit as shown in picture.

(Note: Note that connect the circuit to battery only for 20-30 sec )

Feel free to ask me any questions. I will help you!

    I have to "jump start" lithium batteries frequently in my line of work. My method is much simpler. (This only applies to batteries at 0.0V) I use a 4V 2Ah sealed lead acid battery with leads attached to it. (You can buy flag terminal crimps at most hardware stores) Touch the leads, for as little as 5 seconds, to the appropriate contacts on the lithium battery (positive to positive, negative to negative). Done! You should have voltage now. Enough so, that your phone should be able to charge it again. I've used this process dozens and dozens of times with only one failure.

    Or you can just put it in the freezer. Works every time for me
