  2. Apply proper face charge. Refer to L.T. (Load Test) described on battery caution label.

    For example, if it is 190, apply 190 ampere load.

  3. Remove the load and wait 15 seconds to let battery recover.
  4. Apply same load as in Step  2. Read voltage after 15 seconds.
  5. Remove the load.
    • The voltage does not drop below the minimum as listed in table. - Battery is good.
    • The voltage does drop below the minimum as listed in table. - Replace the battery.
    NOTE: Temperature of battery will affect minimum voltage required to pass load test.
    See the figure and estimate the temperature battery has been exposed to for the last several hours.
