Hyundai Tucson: 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.

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 place the ignition switch in 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.
• The negative battery cable must be removed first and installed last when the battery is disconnected. Disconnect the battery charger in the following order: Turn off the battery charger main switch. Unhook the negative clamp from the negative battery terminal. 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.
