Recently I swapped the OEM battery in my DS Lite with a 1200 mAh one from Ostent. After the swap, I noticed that the battery door doesn't fit as snugly as when the original was installed, and isn't flush with the back of the console, but figured it could be attributed to the extra capacity. When playing, I pressed the on the upper left-hand corner of the touch screen (above the battery), and the console immediately shut down. I tried this a couple more times, and each time the console would power down afterwards. After taking the new battery out and putting it back in, I've noticed that this no longer happens.

Now to the point, I'm considering returning the battery and getting a 1000 mAh one instead. Would that just be a waste of time? From what I can find online, the extra performance from the larger capacity battery is practically negligible, maybe a few minutes at best. But I'm mostly "concerned" about the battery cover no longer sitting flush with the housing.
