Check the State of Charge
Check the indicator to see if the battery is okay, needs to be charged or requires replacement. A voltmeter is preferable for exact check.
If the indicator shows black color, it is necessary to be recharged. And in a general case, it is necessary to be recharged if voltage is under 12.4V.
Calculation of auxiliary charging amount
C = C20 * D * 1.2
T = C / A
