Topic: The "recharge light" flash is it normal ?

When I put my 3DS in the dock for the night the light open just like it should but some time during the night or in the morning the light flash like crazy for a few minutes then goes on or off for a long period... Is it normal ? I never saw that up to a few week ago...

Nope

I think it's because of the contacts wearing out a bit on the dock. I wouldn't worry about it too much, mine does the same.

Hasn't happened to me yet, but who knows.

I just hope it won't make the battery work less longuer because of that...

The charging lens is getting scratched, happened to mine too, nothing to worry about.

So even if I change de craddle it will do the same ? // And woudn't be bad for the battery life to be charge/not/charge/not like that ?

It means that either the contacts on the cradle or on the system itself are getting worn out or corroded. Mine is doing the same, and as I have heard that (at least with some devices) repeated starting and stopping charging can impact the battery's performance, I have just started using the cradle to hold my charge cable. When the system gets low on power, I pull the cable out of the cradle and plug it directly into the system. Not as nice or elegant, but it gives me peace of mind.

Those little contacts on the cradle are fragile, so after a while they wear out. Charge normally or move it arpund in the cradle and it'll be fiine.

It's not as conveniente but I do the same for a week now to be sure that it won't make the battery go "old" faster... My local Walmart got a Craddle for 16.99$ Canadian $ but even if it's kind of cheap I don't want to put money in it if it won't work like it should... Since it's not a game will they take it back if it doesn't work ?

Walmart takes everything back!
