How to handle battery

Precaution

If treated with care and taking the proper precautions, lead acid batteries can be handled safely with minimum risk.
However, lead acid batteries contain sulfuric acid which is both poisonous and corrosive.
This makes them potentially hazardous and can cause serious injury when standard handling procedures and safety measures are not respected.

Safety

  • Always wear acid resistant clothing, protective goggles, PVC gloves and rubber boots.
  • Avoid smoking, sparks and flames near operating or charging lead acid batteries.
  • Keep metal objects away from terminals.
  • Batteries are heavy. Lift carefully and do not place on unstable surfaces.

Emergency Action

  • Splashes in eyes : Wash out the eye with plenty of water for at least 15 minutes.
  • Splashes on skin : Remove contaminated clothing carefully and wash the affected skin areas with plenty of water.
  • Swallowed : Drink copious amounts of milk of magnesia, water or milk. Do not induce vomiting.

Storage

  • Keep batteries upright.
  • Never stack over 4 layers.
  • Batteries should not be directly exposed to the sun.
  • Never drop, never overthrow.
  • Keep batteries clean and always store in a cool, dry place.
  • In all cases, (First in, First Out) storage procedure should be applied.

Installation and recharging

Installation

  1. 01

    Turn off engine,
    all accessories and
    key-off.

  2. 02

    Remove the negative
    cable (Ground) first,
    and then positive
    cable from the old
    battery.

    if clamp or cables are corroded,
    remove corroded material and
    grease it

Recharging

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 voltage charge method
  1. 01

    Measure the OCV(Open Circuit Voltage)of a discharged battery.

  2. 02

    Set the OCV and capacity of the battery with moderate electric current and time stated below table.

  3. 03

    Connect the battery to constant current charger and start charging.

  4. 04

    When the charging time is completed, separates battery from the charger.

Constant current charge method
  1. 01

    Connect the discharged battery to constant voltage charger.

  2. 02

    Charge for 24 hours as following voltage upon battery type.
    - 12V MF Battery: 16V
    - 12V AGM Battery: 14.4V

  3. 03

    When the charging time is completed, separates battery from the charger.

Battery testing procedure

Test

Visual check
  • Check 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.

    Charging Necessary

  • Hankook AtlasBX – Technical Information, Battery Maintenance, Battery testing procedure, Good Condition, Charging Necessary, Replace Battery 03

    Replace Battery

  • Voltage check
    • If 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 rating.
    • Apply 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.
