NOCO GENIUS2X4 Battery Charger - 4-Bank, 8-Amp 6v/12v
The GENIUS2x4 is one of NOCO's highest-performing, most energy-efficient & compact chargers yet. The GENIUS2x4 is a 4-bank, 6V & 12V battery charger, battery maintainer & battery desulfator rated at 8 Amps (2A per bank) 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. GENIUS2x4 includes the battery charger with interchangeable connector, 4x clamps with integrated eyelets (M6), 4x extension cords, 2x screws and user guide.

2 motorcycle batteries, 1 RV battery, and 1 side by side battery charging and maintained all at once. Instead of buying 4 battery maintainers, bought one of these units. hooked them up and green lights all the way around. It even comes with 10 ft extension cords so you can reach machines all the way around. sitting in an unheated garage seems to have no issues even when it's -40 outside.

This is the third NOCO Genius product I have purchased. This thing is obsoletely the best. I have plugged in 4 batteries at once that have sat outside for 1.5 years, that hydro and load test poorly.. but not shorted and have had a lot of success at bringing a couple of full sets back from the dead to load testing well and Hydro'ing at the bottom of the green! This Wonder Machine has saved me a ton of money!!

NOCO knocks it out of the park again. Great charger and plenty of accessories. Slim clamps works great in tight engine bays and jet ski hulls. If you need to charge deep cycle batteries or anything over 40Ah this is not the charger for you. Get the Genius 10x4.
Let's just say a big family with at least 3 or four vehicles and you want to prepare them for a atmospheric event, just need one charger to revive up their heart(batteries) and if your house is powered by lithium batteries! Guess what? You have it all in one. Light weight, quiet and durable.
I bought this to keep the batteries fresh from 4 vehicles in winter storage. This battery tender comes with all attachments and extensions that enabled me to select different battery types, easily to read indicators for charge level, battery problems and will check for and automatically desulfate batteries to increase their life. Product worked as described.
Excellent maintenance charger for multipul motorbikes , jetski , utv , atv etc. parked close together in your garage or shed. Maintain four batteries at once.
I believe this is for smaller batteries because it struggles to get a full charge on my car size marine batteries. It will charge them most of the way and if given long enough it will fully charge larger batteries. I recommend a higher amp charger for marine applications. In the off season for fishing and for storing auto batteries this makes a great trickle charger.
I don't know how useful a 4 battery charger is to most people, but if you have 4 AGMs you have to charge at a time this thing is perfect. I thought that it being only 2A per charger wouldn't be enough but it charges 100ah batteries over night no problem. It's nice that the settings are remembered even after unplugging it.
I have used Noco chargers and battery tenders for years on my bikes and this new 4 bike unit is the best yet as it will manage all battery times, is fully automatic AND can be manually set to recondition batteries that have gone completely flat if they have gone so recently. BUT not if they have been left dead for some time.
