14.1The Chart Method

Use the following table to more accurately determine the time it will take to bring a battery to full charge. First, identify where your battery fits into the chart.

•Small batteries — motorcycles, garden tractors, etc. — are usually rated in Ampere Hours (AH). For example: 6 to 12 AH, or 12 to 32 AH.

•Batteries in cars and smaller trucks are usually rated in Reserve Capacity (RC), Cold-Cranking Amps (CCA), or both.

•Marine or deep-cycle batteries are usually rated in Reserve Capacity (RC).

•NR means that the charger setting is NOT RECOMMENDED.

Find your battery’s rating on the chart below and note the charge time given for each charger setting. The times given are for batteries with a 50-percent charge rate prior to recharging. Add more time for severely discharged batteries.
