I have a Sega Gamegear and i just ordered a original Atari Lynx. Usally i use the power adapter for the gamegear due to in about 2 Hours the 6AA's Ran out real quick on me. Since the Lynx is alittle larger and im guessing has a little bit bigger screen it will suck the life out of original Alchaline AA's. Ive been looking at the Entergizer website and they have these Hi-Power Rechargeable,Titanium and Litium Batterys. Buy what the site says these high tech batterys last longer in high tech devices like digital cameras and mp3 players. So my question is has anyone tested these batterys in there Lynx or Gamegear and how long did they last?
