NOCO GENIUS1EU Battery Charger, Maintainer and Desulfator

NOCO GENIUS1EU Battery Charger

NOCO GENIUS1EU is an ultra-compact and high-efficiency 1-Amp 6-volt and 12-volt battery charger, battery maintainer, and battery desulfator for lead-acid and lithium-ion batteries.  

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

NOCO GENIUS1EU can charge safely 24/7 without any risk of overcharging your batteries.
Additional safety is provided by spark-proof connections, and reverse polarity protection.

The GENIUS1EU charges dead batteries as low as 1-volt. The all-new Force Mode allows you to take control and manually begin charging dead batteries down to zero volts.
