Hi, all there,

Like I said in the earlier thread, the OEM battery is not a problem in China now.
Because most of the Nokia batteries (or you can say almost all the cellphone batteries / MP3 player batteries ) are produced in China, Guangdong province.

There are many versions BL-5J here and the quality is also very good.

The same quality with only 1/6 in price. Like here :

And for the size of BL-5J, the maximum capacity should be about 1350mAH.
Any capacity above 1350mAH is not the true number.

I am using a early version 1250mAH PISEN battery.

The official website is here :

PISEN is a famous brand in China. And many other brands make batteries for NOKIA / Apple cellphones.

In the battery-eye in my N900, it shows 1260mAH.
