I've heard that backlights don't drain that much extra battery in comparison to a stock-standard GB.
As for which batteries I use, I barely use them.
I have a homebuilt AC Adapter at hand when I'm in music class or at home, a USB power cable I built myself for hooking up to my laptop, and one set of AAs for when I'm on the road or out of the vicinity of a USB port or mains power.

I've used the same set of AAs since May this year, and they're still kicking. I've probably only used them for a total of five hours.

When using the ems64 usb carts on battery power (or on ac power if the cable slips out), there's a 9/10 chance the memory block you are writing your song in will be corrupted if you lose power while tracking, I've got 4 of these carts and the problem spans across all 4 of them, Just a heads up.

My experience with battery life on the DMG is that for me, I get about a week of usage before the battery gets low. I know that because my backlight dims when the battery gets low. Overall I was amazed with the life of the batteries on this dmg.

Doesn't seem to be as though anyone is worried about it much, and the DMG seems to work fine but I'm curious as to what is going on electrically in this case. I was under the impression that the DMG stepped 6V down to 5V for everything but the LCD. I assumed a regulator was used for that, but a linear regulator would not work in cases where you were already under the output voltage, no?

If you want good rechargeables, its going to be like 100 for a good set that will last for 100s of charges. NiMh batteries have advantages over LiPo, Li-Ion, and LiFe batteries as they perform better in the cold and heat. Lipo batteries have an extremely consistent voltage right until the end, problem with them is you need to balance charge each cell, and make sure to never over charge or discharge as they will catch fire. LiPo batteries have 3.7v usual per cell, NiMh is 1.2v. Lipo batteries may be the best to use in the case of a rechargeable but the practicality of buying a balance charger then creating a circuit to provide the gameboy with the proper voltage is a huge hassle. I run energizer 2500mah (NiMh) rechargables and use my really expensive RC charger to peak charge them perfectly every time yielding wonderful results.

Also, I had to remove the power led to make the mod (LEDx3). So, for those thinking about why people take it off.

There is a fix for the flickering, I read it in nonfinite's website the other day.

But it was actually good, I knew the battery was dying! It doesn't happen when the batteries are ok.

I use 2700mah recharagables, and probably run through a charge twice a month or so.

I have a rather nice charging station though that lets me control how fast/slow to charge batteries, has a discharge feature, among other things. I think the negative feedback I see from rechargeables is due to crappy chargers and/or poor handling.

That said, I've been wondering about creating an external battery pack using lithuim batteries. SparkFun has some nice offerings that should make it pretty easy to do, I would think.
