So i bought My DS lite when it launched and i've been using Flascarts since the m3 lite came out. then i switched over to the Real once that came out and i used the Rumble Pack . Now My battery is starting to die alot quicker and i dont know if its the Rumble Pack or not. I stopped using any kind of slot 2 device but my battery is still giving me about 2.5 hours of the highest brightness with out a rumble pack on a full charge. Should i just buy a new battery or does my battery need to recover
