Carregador de bateria NOCO GENIUS2X2 4A 2 saídas, 4A total, duas saídas independentes

NOCO GENIUS2X2 4A 2-bank is a compact battery charger that delivers a combined 4A charging current through two independently controlled outputs. It is designed to charge and maintain two 12V lead‑acid or lithium batteries simultaneously, using multi‑stage charging algorithms that optimise charge, reduce overcharging risk and prolong battery service life. The unit is suitable for vehicles, small boats, ATVs, motorcycles and other equipment where dual‑battery maintenance or simultaneous charging is required.

Advantages

The charger provides two independent charging channels so batteries of different capacities or chemistries can be charged simultaneously without cross‑interference. Automatic multi‑stage charging adjusts current and voltage throughout the charge cycle to maximise battery health. Integrated protection features guard against reverse polarity, short circuits and overcurrent, while an automatic maintenance mode holds batteries at optimal charge once fully charged. The compact housing and straightforward connectors make installation and storage convenient.

Suitable for

• Charging and maintaining dual 12V starter or deep‑cycle batteries on cars and trucks
• Maintaining batteries on small boats and marine tenders
• Servicing batteries for ATVs, UTVs and motorcycles
• Keeping batteries topped up on lawn equipment and seasonal vehicles during storage
• Charging lithium and lead‑acid batteries in workshop or garage settings

Key specifications

• Output configuration: two independent charging outputs
• Total maximum charge current: 4 amps
• Battery types supported: 12V lead‑acid (including flooded, AGM, gel) and 12V lithium
• Charging stages: multi‑stage smart charging with maintenance/float mode
• Protection features: reverse polarity protection, short‑circuit protection, overcurrent protection
• Form factor: compact, wall‑mountable housing suitable for garage or onboard installation

How to use

Connect the charger to a standard AC outlet, then attach the charger leads to each battery following polarity indicators: positive to positive, negative to negative or to a suitable chassis ground when specified by the vehicle manufacturer. Select the appropriate charging mode if the unit requires manual mode selection for battery chemistry; otherwise the charger will automatically detect and apply the correct charging algorithm. Monitor the charger indicators to verify charging progress and wait until the maintenance/float indicator shows the batteries are fully charged before disconnecting. Disconnect AC power first, then remove battery connections in reverse order.

Recommendations

Store and operate the charger in a dry, well‑ventilated area and avoid exposure to extreme temperatures. For long‑term battery storage, leave the charger connected in maintenance mode to prevent discharge and sulfation of lead‑acid batteries. Inspect battery terminals for corrosion prior to charging and clean as necessary to ensure reliable contact. Follow manufacturer instructions for batteries with special charging requirements and avoid using the charger on batteries with visible damage or leaks.
