Battery recharging
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 - Recharging

ing rate if the battery cells begin
gassing (boiling) violently or if
the temperature of the electrolyte
of any cell exceeds 49°C (120°F).
Wear eye protection when check- ing the battery during charging.
Disconnect the battery charger in the following order.
1. Turn off the battery charger main switch.

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 author-ized HYUNDAI dealer.
Do not open or remove the cap on top of the battery. This may causeleaks of internal electrolyte that
