Hyundai Genesis: Battery / Battery recharging

By battery charger

Your vehicle has a maintenance-free, calcium-based battery.

  • If the battery becomes discharged in a short time (because, for example, the headlights or interior lights were left on while the vehicle was not in use), recharge it by slow charging (trickle) for 10 hours.
  • If the battery gradually discharges because of high electric load while the vehicle is being used, recharge it at 20-30A for two hours.

CAUTION

AGM battery

  • Absorbent Glass Matt (AGM) batteries are maintenancefree and we recommend that the AGM battery be serviced by an authorized HYUNDAI dealer. For charging your AGM battery, use only fully automatic battery chargers that are specially developed for AGM batteries.
  • When replacing the AGM battery, we recommend that you use parts for replacement from an authorized HYUNDAI dealer.
  • Do not open or remove the cap on top of the battery. This may cause leaks of internal electrolyte that could result in severe injury.

WARNING

Always follow these instructions when recharging your vehicle’s battery to avoid the risk of SERIOUS INJURY or DEATH from explosions or acid burns:

  • Before performing maintenance or recharging the battery, turn off all accessories and press the Engine Start/ Stop button to the OFF position.
  • Keep all flames, sparks, or smoking materials away from the battery.
  • Always work outdoors or in an area with plenty of ventilation.
  • Wear eye protection when checking the battery during charging.
  • The battery must be removed from the vehicle and placed in a well ventilated area.
  • Watch the battery during charging, and stop or reduce the charging rate if the battery cells begin boiling violently.
  • The negative battery cable must be removed first and installed last when the battery is disconnected. Disconnect the battery charger in the following order:
    (1) Turn off the battery charger main switch.
    (2) Unhook the negative clamp from the negative battery terminal.
    (3) Unhook the positive clamp from the positive battery terminal.
  • Always use a genuine HYUNDAI approved battery when you replace the battery.

By jump starting

After a jump start from a good battery, drive the vehicle for 20-30 minutes before it is shutoff. The vehicle may not restart if you shut it off before the battery had a chance to adequately recharge. See “Jump Starting” in chapter 6 for more information on jump starting procedures.

✽ NOTICE

An inappropriately disposed battery can be harmful to the environment and human health. Dispose the battery according to your local law(s) or regulation.
