NOCO Genius 5 EU 6V/12V 5A smart battery charger

The NOCO Genius 5 EU is a compact 5 A smart battery charger for 6 V and 12 V lead-acid (flooded, gel, AGM, MF, SLA) and lithium-ion (LiFePO4) batteries. It charges, maintains and desulfates batteries in cars, vans, motorcycles, boats, RVs, ATVs, lawn mowers, snowblowers, tractors and many other applications.

Multi-voltage, multi-chemistry design: one unit covers 6 V and 12 V batteries across multiple chemistries and types. The all-new Force Mode manually charges flat batteries below 1 V — down to 0 V — and the integrated thermal sensor automatically adjusts the charging cycle to ambient temperature, preventing overcharging in hot climates and undercharging in cold ones.

Precision pulse charging detects and reverses sulfation and acid stratification to restore lost capacity and extend battery life. The Genius 5 includes 24/7 overcharge protection, spark-proof technology and reverse polarity protection.

Key features:

• Charger, maintainer and desulfator — 3 functions in one device
• 6 V and 12 V output, 5 A charging current
• For lead-acid (flooded, gel, AGM, MF, SLA) and lithium-ion (LiFePO4) batteries
