Hyundai Elantra: Battery / Battery Recharging


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 place the ignition switch to the LOCK/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.
  • Vehicle is equipped with the Absorbent Glass Mat (AGM) battery. Do not charge the AGM battery with a general charger. It may damage or explode the AGM battery. Only charge the AGM battery with a charger that has AGM battery setting.
  • 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.


AGM battery

  • Absorbent Glass Matt (AGM) batteries are maintenance-free 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.

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 7 for more information on jump starting procedures.


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