Actually I have a doubt whether battery health could be checked accurately (I mean, telling like 75% good or 45% good).  By which parameters the health status could be given accurately.?

It can be checked accurately. The parameter to check is "Hybrid battery usable capacity". In Honda Ni-MH batteries the max capacity is 75%. If the usable capacity is 35%, that means the battery has 35/75% of its original capacity.

Isn't those are the variables controlled by the battery management program and not the unique values related to the battery health condition?

Value controlled by the battery control module is called the State of Charge (SoC). It's a value that moves between 0-100% regardless of the usable capacity. 

I forgot to mention earlier that BCM will reset the 'usable capacity' when the system is reset. But it will always normalize to the actual value once you run 100-200km or more. So when getting the report, always ensure that it is not taken immediately after a system reset (this can be figured out in the same report as it shows the mileage since last reset).

Good Info.

Are the system reset on Honda Fit GP1 can be done by a scanner or disconnecting 12V battery or from both way will reset usable capacity?

AFAIK only the Scanner can fully reset the IMA. Disconnecting the battery terminals would clear out any error codes (DTC) and force a re calibration of the BCM.
