I'm using GOKI for NK BL5J as a spare battery for N900. Its sticker says "Made

Below please find the hal-device dme dumps for your reference:

Orignal Nokia battery comes with N900
Code:
  battery.reporting.design = 1258  (0x4ea)  (int)
Hope this help.
This is unfortunately quite irrelevant.

BME does not read the capacity of the battery using any charge meter - it simply measures the value of one component - a resistor - in the battery - which is set to indicate the designed capacity of the battery.

This means that a battery can declare whatever capacity it wants - simply by changing that $.005 component.
This does not however change the fundamental capacity of the battery.
That could in principle be measured by the http://wiki.maemo.org/N900_Hardware_Charge_Meter onboard charge meter - but this is not functional with the existing software.

Early models of the mugen battery - while having a greatly increased real capacity read very low on BME due to this.
