Sears 200.713201 Calculating Charge Time, Battery Battery Rating Charge-Time Hours Type, Cca Amp

CALCULATING CHARGE TIME

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 (AH).

•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

Charge Time Table for Batteries at 50% State-of-Charge

Voltmeter Method

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.
