LENGTH OF CHARGE
The following instruction will allow you to determine how long it will take to bring a specific battery to full charge.
a. Test the battery for state of charger with a hydrometer or electronic percent-of-charge tester.
b. Determine the size of the battery in Amp-Hour or Reserve Capacity. If the ratings are not printed on the battery, contact
your local battery dealer for this information. These are the only ratings that can be used to determine length to charging
time.
