Okay, now, let's help the person.
There's an obvious encoding problem here - weirdly enough, his text is in UTF-8... I changed all the encoding - and voila, Chinese shows, though still with some weird question marks.
Anyway, my translation from Chinese:
OP bought a K200D in the end of 2008. In 2009, camera started showing newly charged batteries as dead. Since it didn't happen too often, he didn't pay too much attention to the problem. Now, it occurs all the time (I think that's what he said - there are a lot of question signs instead of letters here and I have to guess)
So, OP has no idea what's going on and if this situation has happened to anyone here.
Also, he says that the kit lens he's got has no dust - but there's a shadow visible at right bottom of his shots. My guess is that it's sensor dust - so I'll explain that to him next.
LZ,你问题显示出来全是乱码,我把它翻译成英文了,看有人知道不知道电池问题咋搞。
对于黑影,试试把光圈调成f/16, 照一张白纸或者是墙 (不要聚焦),看结果像不像灰尘。你问题应该不是和镜头有关,而是你相机里的CCD有灰。我建议你用Giottos Rocket Blower(不确定中国有没有卖,类似于这样的 - 里面一定要有一个过滤器,过滤灰尘)吹一吹CCD。
为了清洁感应器,你得要能用充满电了的相机 - 所以还是先把电池问题搞好再说吧
