Hyundai Equus: 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 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.
