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.
