Battery Check

BATTERY TESTING PROCEDURES

A. VISUAL CHECK

A 1. Check the Container , Cover and terminals When physical damage is present, replace the battery.
A 2. Check the Indicator (If battery have the Indicator) Always look right down when viewing the Indicator and lightly tap the Indicatoron the battery to dislodge any air bubbles.

B. VOLTAGE CHECK

  • If OCV is below 12.4V, recharge the battery immediately.

C. 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 rating
  • Apply the load for 15 seconds and read the voltage when this time is over.
  • Compare measured values with the values in the table. If values is outside in
    TABLE.2,

recharge and test again. If the battery fails the load test twice, then replace the battery.
Some times, 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.

BATTERY CHARGE

If the battery is below 12.4V or fails to pass the load test, battery must be recharged as soon as possible to prevent lead sulfation. During charge, if the battery sprays electrolyte through the vent holes or gets hot (over 52???), the charge must be stopped for a time to allow the battery to cool.

CONSTANT CURRENT CHARGE
General guidelines for constant-current-charge are given in Table 3.
The table summarizes approximate amperes and hours in need of charge according to 20Hr-rate capacity and OCV.

CONSTANT VOLTAGE CHARGE
Another method is to charge a battery at a specified voltage(14.4~16V). At the beginning of charge, a high rate
current flows into the battery and as battery is charged the current is getting reduced. Generally this method needs
more time than the constant-current-charge, but overcharge risk is less.

END OF CHARGE
If a battery has been properly charged, voltage output across battery terminals on charge can be maintained at
constant level for 2 hours.
