Battery Charging

Using a Battery Charger

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

• If the battery has been discharged in a short time (for example, the headlights or interior lights were left on while the vehicle was not in use), recharge it with a slow charge (trickle charge) for 10 hours.
• If the battery gradually discharges due to high electrical load while the vehicle is in use, charge it at 20-30 A for two hours.

CAUTION

AGM Battery

• Absorbent Glass Mat (AGM) batteries are maintenance-free, and we recommend that an AGM battery be serviced by an authorized HYUNDAI dealer. To charge your AGM battery, use only fully automatic battery chargers that are specifically designed for AGM batteries.
• When replacing an AGM battery, we recommend that you use replacement parts from an authorized HYUNDAI dealer.
• Do not open or remove the cap on top of the battery. This may cause internal electrolyte to leak, which may result in serious injury.

WARNING

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

• Before performing maintenance or charging 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 a well-ventilated area.
• Wear safety glasses when checking the battery during charging.
• The battery must be removed from the vehicle and placed in a well-ventilated area.
• Monitor the battery during charging, and stop or reduce the charging rate if the battery cells begin to boil violently.
• The negative battery cable must be removed first and installed last when disconnecting the battery. Disconnect the charger in the following order:
  (1) Turn off the charger main switch.
  (2) Disconnect the negative clamp from the negative battery terminal.
  (3) Disconnect the positive clamp from the positive battery terminal.
• Always use a genuine battery approved by HYUNDAI when replacing the battery.

Jump Starting

After starting from a good battery, drive the vehicle for 20-30 minutes before turning it off. The vehicle may not restart if you turn it off before the battery has been adequately recharged. See "Jump Starting" in Chapter 6 for more information on jump starting procedures.

✽ NOTICE

Improper disposal of the battery can be hazardous to the environment and human health. Dispose of the battery in accordance with your local law(s) or regulation(s).
