How to make it :

1. Print out the PDF document : charge_indicator.pdf
  ( alternative version with numbers : charge_indicator_2.pdf )

2. Cut out the indicator, fold and tape it on the inside of the battery case.

3. How to use it :
- Place the positive side of the battery to the green if its charged
   and turn it around to the red side if it is empty.

it is more practical to tape a single sided indicator on the outside.
