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.
Battery recharging by vehicle
After a jump start from a good bat-
tery, run the engine for 20-30 min-
utes at idle or driving the vehicle
before it is shutoff. Vehicle may not
restart if you shut it off before the
battery had chance to adequately
recharge.
CAUTION
• When you don’t use the vehi-
cle for a long time in a low
temperature area, disconnect
the battery and keep it
indoors.
The power trunk is not closed
completely when the battery is
removed. When you remove
the battery from the vehicle,
refer to "Power trunk" in sec-
tion 4.
• Always charge the battery
fully to prevent battery case
from being damaged in a low
temperature area.
• If you connect unauthorized
electronic devices to the bat-
tery, the battery may be dis-
charged. Never use unautho-
rized devices.
WARNING
Removing the battery from the
vehicle should be done at an
authorized EQUUS dealer.
