ok thanks. I have many rechargeable AA Panasonic Evolta (2200-2550 mAh) but I don´t want to use them because of lower voltage. Rechargeable AA have only 1,2 V, real around 1,33 V I think, so for me they don´t last too long and they are heavy.. Standard AA have 1,5 V real around 1,45 I think, not sure. Low voltage alarm in GT5 is set to 4,4 V I think, so I´m afraid to use AA rech for longer expedition. But maybe my rech AA are older so They don´t last enought. In Xbox controller They last almost 2 weeks but in GT5 maybe 2 hours?
