DS development > DS Battery Info Request?

Hey,
I saw a pic of the DS battery, which Nintendo is selling at this website:

http://store.nintendo.com/html/Nintendostore/prodlink.html?part=83647&parent=58694

But the pic is too small to read anything off of. I was wondering if anyone could take the DS battery out and tell me what the voltage and mAh rating is? And the DS battery looks strikingly like the SP battery...could anyone compare the two and tell me if they are the same size/dimensions? Because then I could order a spare DS battery and replace the SP battery with that one.

Thanks,
Robert Aldridge

According to http://www.lik-sang.com/news.php?artc=3530

It just uses a GBA SP battery that's had the sides sanded down.

3.8V, 600 mAh according to this shot: http://forum.lik-sang.com/other/nds-release/nds-release18.jpg

Oops. Yeah, the DS battery in that shot does say that. I was looking at the GBA battery. Mea culpa.

I was thinking that since the battry recharge ratios are about the same for the DS and the SP, Nintendo could have released a battery charger that would recharge the DS batter much faster than 4 hours (considering the SP charges in 3).

GBA SP: 600 mAh, 3 hours
Nintendo DS: 850 mAh, 4 hours

Based on those numbers, it looks like the charging circuit pumps 200 mA or so either way. It may be some inherent limit against overheating.
