Reg: bq27000 battery monitor

[shariff]

Hi all,

      On our custom board we are bq27000 battery monitor chip.

      I charged the battery up to 40%(i.e from RSOC register of bq27000).

      After that I disconnected the battery and connected it after 10min.

      Now its showing 0%( i.e from RSOC register of bq27000)

      Why this strange behaviour is there?

      Is there any other way to calculate the exact capacity from other
registers of bq27000?

      Can anybody help me solving this issue?

Regards,
Shariff
