Step 15: Enjoy not Using the Charger!
Ever since I did this to my DS, I have never had to plug it in to charge it. If you have used for a while, set it in the sun to charge some. ~~Don't let it sit in the sun all day every day, it's probably bad for the battery. The cells don't produce much current, but it's probably best not to risk the battery.~~ (see update)
Enjoy your DS "light"! :-)
