Remaining Active Relative Capacity (RARC) [%]: RARC reports the capacity available under the current
temperature conditions at the Active Empty discharge rate (IAE) to the Active Empty point in relative units of
percent. RARC is 8 bits. See Figure 16.

Remaining Standby Relative Capacity (RSRC) [%]: RSRC reports the capacity available under the current
temperature conditions at the Standby Empty discharge rate (ISE) to the Standby Empty point capacity in relative
units of percent. RSRC is 8 bits. See Figure 17.

Calculation of Results
RAAC [mAh] = (ACR[mVh] - AE(T) * FULL40[mVh]) * RSNSP [mhos]
RSAC [mAh] = (ACR[mVh] - SE(T) * FULL40[mVh]) * RSNSP [mhos]
RARC [%] = 100% * (ACR[mVh] - AE(T) * FULL40[mVh]) /
{(AS * FULL(T) - AE(T)) * FULL40[mVh]}
RSRC [%] = 100%* (ACR[mVh] - SE(T) * FULL40[mVh]) /
{(AS * FULL(T) - SE(T)) * FULL40[mVh]}
