Initial Charge of 3DS

Pluged in my 3DS a little under 3 hours ago and just noticed the charging litght turn off on the 3DS but I picked it up and put it down again and the charging indiciator came back on.

I will let the 3DS keep on charging until it goes off again... but I want to make sure its first charge is 100% (Haven't booted yet)

Its probably already charged. I mean if the charge light turns off it has to be fully charged. The charge usually takes 3 hours and 30 minutes for a full recharge.

I charged it for two hours before playing it, if that helps

Should be fully charged. Mine only took about 2 hours.
