Ohh...No.....Don’t Throw Your Empty Battery

In this post, I want to share about 1.5 Volt batteries that have been discharged. You have many empty battery in your house? Sometimes a battery that we use have not really empty. Generally, people will throw it away. but the battery still save a little of energy that can be used with a simple trick.


Joule thief is one of the tricks to use empty battery, joule thief will increase the battery voltage up to dozens volt. Joule Thief circuit is very simple to make. Many articles on the Internet that post this circuit, many communities on social media sharing and experimenting about this circuit. People often call this circuits with “JT”
Main component is

>> Transistor type C 9014
>> 14:14 coil with ferrite toroid from Power Supply of CPU and  wire from UTP cable.
>> 680 Ohm Resistor
>> 5 Watt LED HPL
>> Small Switch
>> Battery Housing
>> 1.5 Volt AA Battery

Joule thief is able to turn on the HPL LED only with 1 piece of 1.5 Volt battery. HPL LED is High Power LED which can lit if get voltage supply around 2.8 Volt. I use this circuits to emergency lamp. Besides that, I want to take advantage from empty battery before it really discharge.  So, there are many people develop this circuits become a mobile charger. Of course this makes me interested to try it. You can look this picture and video for more detail.
