Battery Rating Method
Use the following table to more accurately determine the time it will take to fully
charge a battery that is initially at 50% State-of-Charge. Identify your battery type and
its associated Charge Time in the table. Common battery types are:
• Small batteries, motorcycles, garden tractors, etc., are usually rated in Amp-Hours
(AN).
• Car and truck batteries, usually rated in Reserve Capacity (RC), Cold Cranking
Amps (CCA), or both.
• Marine, or deep cycle batteries, usually rated in either Amp-Hours or Reserve
Capacity (RC).
• NR means the charger setting is NOT RECOMMENDED.
• NA means not allowed. DO NOT charge at this setting

To find the time needed to fully charge your battery, determine the battery's charge
level with a voltmeter or electronic State-of-ChargeTester. Use the table below to
convert Voltmeter and State-of-Charge readings at room temperature to the appro-
priate Charge Factor. Then use the formulas that follow the table to determine the
approximate Charge Time.
