Maintenance
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
whilst 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 whilst the
vehicle is being used, recharge it at 20-
30A for two hours.
