CHARGING TIME INSTRUCTIONS
First, determine percent-of-charge-NEEDED to bring the battery to
full charge. This is 100% minus the present percent of charge of
the battery (determined above). Then, to use it in the equation,
express the percent-of-charge-needed as a decimal.
EXAMPLE:
Battery,s Present State of Charge = 25%
Percent-Of-Charge-Needed: 100% - 25% = 75%
To express as a decimal, insert a decimal point two digits to the
left of the percent sign (%), then drop the percent sign: 75% = .75
Next, use this decimal in the equation below, along with the =
battery's amp-hour rating, and the charge rate (amp) setting
selected on the charger, to determine time to charge,
