VISUAL CHECKCheck the Container, Cover and Terminals. Where physical damage is present, replace the battery.Check the Indicator (If the battery has the Indicator). Always look right down when viewing the Indicator and lightly tap the Indicator on the battery to dislodge any air bubbles.



VOLTAGE CHECKIf OCV is below 12.4V, recharge the battery immediately.DISCHARGE TEST(LOAD TEST)Connect the battery tester to battery terminals.Measure the temperature of the battery around.Set the battery tester ampere values for ½ of the CCA ratingApply the load for 15 seconds and read the voltage.Compare measured values with values in TABLE 2.If the values are outside of the table values, recharge the battery and test again.If the battery fails the load test twice, replace it.Sometimes, electronic testers such as MIDTRONICS, SNAP-ON and etc are used instead of load tester.Electronic testers are only suitable for batteries that have been in use for a certain time.They cannot rate the performance of new or unused batteries.For this reason, ATLASBX recommends the test defined in global standards to confirm rated specifications.
