NOCO GENIUS5AU, 5-amp Fully-Automatic 6V and 12V Smart Battery Charger, Maintainer, Desulfator With Temperature Compensation
The GENIUS5 is one of NOCO's highest-performing, most energy-efficient & compact chargers yet. The GENIUS5 is a 6V & 12V battery charger, battery maintainer & battery desulfator rated at 5 Amps for lead-acid automotive, marine & deep-cycle batteries, including flooded, gel, AGM & maintenance-free, plus lithium-ion batteries. The NOCO Genius range is completely automatic. Genius chargers will safely charge any battery with no technical knowledge required. They will detect damaged batteries and intuitively repair them. Beyond just repairing damaged batteries, Genius chargers actively monitor for long-term battery maintenance and help extend battery life. This system allows for continual operation without user intervention and zero risk of overcharging your battery. Genius uses an integrated thermal sensor to detect the ambient temperature and alter the charge to eliminate over-charging in hot climates & under-charging in cold climates. They will charges dead batteries as low as 1 Volt, or go manual with the new Force Mode that allows you to begin charging dead batteries down to zero volts. Connect Genius to the battery, plug in and select a charge mode to start charging your battery. Genius is a fully-automatic, worry-free battery charger for year-round use. The charger detects sulfation and acid stratification then restores lost performance for stronger engine starts and extended battery life. GENIUS5 includes the battery charger with interchangeable connector, clamps with integrated eyelets (M6), mounting bracket and strap with 2x screws and user guide.

Great little charger. Easy to use and the compact size is good. Only concern, that it gets pretty hot.

Great price for such a small, powerful charger. This completely restored our flat car battery and saved having to buy a brand new one.
Easy to use, Charged batteries as described. Well packed and feels a solid unit.
Bought this today from SCA Menai. Sent the misso to get it. Staff very helpful today and also historically when i have been out there to get stuff.NOCO Genius 5- Packaging looks very good quality.- Designed in USA- Instructions clear and consise.- All parts look and feel good quality- Unit is IP65 rated so can be used outside- Has about 1m cable at both 240v side and battery side - makes it easy to connect up and close bonnet- unit is intuitive to look at and work out- running fine so far- very happy so far
I was after the 15amp but the only lithium charger in stock was the 5 amp version. Does the job but just slower. It is a well made compact charger.
Works as per advertised. Happy with the purchase. Would be a great option to have an Anderson plug option also
Great charger, instructions are clear, eyelets on battery clamps could be bigger to suit battery terminal eyelets for permanent install. Others very well made and certainly a much better option than most generic brand chargers, would say a better option than the ctek brand as well .
Doesn’t live up to the hype - didn’t charge a flat battery. Wouldn’t trickle charge a healthy battery - go figure!
