Hi everyone, I have a problem. I bought used DSi in perfect condition, but the battery life is very bad, about 2 hours on backlight level 5 with AK2 and DS game. Later I bought a battery for replace from DX, but it runs ~2h too. Then I bought a battery "DragonPRO 1800mAh" from eBay, but it is identic chinese noname, and runs even less. I used amperemeter to measure DSi power consumption and it says that is about 230 mA (backlight 5, AK2i). If battery runs 2h with this consumption, it's real capacity is about ~500mAh. It is 40% less than DSi original battery 850mAh. But I can't find any possibility to buy original battery. eBay sells only noname or used, DX too. It is possible to buy unused original battery? I live in Russia, thus I need a seller that can ship overseas. Sorry for my bad English and thanks for replies. Warning: Spoilers inside!
