NOCO Genius5 6V/12V 5-amp Battery Charger

We’ve gone through a few chargers, and this one is the best we’ve tried.

The GENIUS5 is a 6-volt and 12-volt battery charger, battery maintainer, and battery desulfator rated at 5-amps for lead-acid automotive, marine, and deep-cycle batteries, including flooded, gel, AGM, and maintenance-free, plus lithium-ion batteries.

• The all-new GENIUS5, one of NOCO’s most powerful, highest-performing, energy-efficient, and compact chargers yet.

• Designed for 6-volt and 12-volt lead-acid automotive, marine, and deep-cycle batteries, including flooded, gel, AGM, and maintenance-free, plus lithium-ion batteries.

• An integrated thermal sensor detects the ambient temperature and alters the charge to eliminate over-charging in hot climates and under-charging in cold climates.

• Charge dead batteries - Charges dead batteries as low as 1-volt. Or use the all-new Force Mode that allows you to take control and manually begin charging dead batteries down to zero volts.

• Simple to set up and use - Plug-in, connect to the battery, select a charge mode, and start charging your battery. A fully-automatic, worry-free battery charger for year-round use.

• Restore your battery - Detects sulfation and acid stratification and restores lost performance for stronger engine starts and extended battery life.
