I was having few old laptop batteries in my junkyard therefore I have decided to make some use of those batteries. Normally laptop batteries are of 3.6 to 4V rating therefore I have searched a LED strip from market here in Pakistan those LED strips are very common and easily available therefore I have selected a strip of 18LEDs, such strips are available for 20 cents (20 Rupees) from Pakistani market.

Now I have purchased Nokia battery charger socket a charging indicator LED and a switch and a diode all those spares are available for 10 cents (10 Rupees)
