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 exam-
ple, 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.
AGM battery
• Absorbent Glass Matt (AGM)
batteries are maintenance-free
and we recommend that the
AGM battery be serviced by an
authorized retailer of Genesis
Branded products. For charging
your AGM battery, use only fully
automatic battery chargers that
are specially developed for AGM
batteries.
• When replacing the AGM bat-
tery, we recommend that you
use parts for replacement from
an authorized retailer of Genesis
Branded products.
• Do not open or remove the cap
on top of the battery. This may
cause leaks of internal elec-
trolyte that could result in
severe injury.
NOTICE
Always follow these instruc-
tions when recharging your
vehicle's battery to avoid the
risk of SERIOUS INJURY or
DEATH from explosions or acid
burns:
• Before performing mainte-
nance or recharging the bat-
tery, turn off all accessories
and press the Engine Start/
Stop button to the OFF posi-
tion.
• 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.
