NOCO GENIUS2X2 6V/12V 2-Bank 4-Amp Smart Battery Charger
The GENIUS2 is one of NOCO's highest-performing, most energy-efficient & compact chargers yet. The GENIUS2 is a 6V & 12V battery charger, battery maintainer & battery desulfator rated at 2 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. GENIUS2 includes the battery charger with interchangeable connector, clamps with integrated eyelets (M6), mounting bracket and strap with 2x screws and user guide.

The 24v charger on a commercial building sweeper failed and a replacement cost about $1000. I bought the double charger, hooked one output to each battery and it has worked perfectly so far. The batteries are deep-cycle but the charger is able to handle it although it may have a problem if the chargers were used excessively day-in and day-out.

Bought this to keep a small boats batteries topped up whilst on shore power in a marina. Excellent for a dual bank battery system as is very compact and comes with a comprehensive set of leads and all feel top quality.

This charger is primarily used to maintain the batteries in your boat. I always charge both my batteries individually rather than wait days for my onboard charger to charge them.

One side of the 2 failed almost immediately. I messaged NOCO about it and they said to change the fuse. I changed it and it happened right away again. Since it was so new I just returned it. I like the ease of these, but I hope they're not failing too often.
Working great on my 2 snowmobiles for keeping battery topped up and ready to go between using them. Like how you can just for about it once hooked up. This is the third NOCO product, great quality. Also have their booster pack and larger charger.
I am disabled with ALS. I had to charge my Permobil M300 power wheelchair which has 2 gel batteries. This product pulse charged bot batteries at the same time. Great product!
Quite impressed with the quality!I was originally looking for a Ctek, the guys suggested I look at the NOCO range so I chose this unit, as it was able to charge 2 cars at once and is wall mountable. Cables are 3m long to clips so they go across my garage. The item is higher quality in every way than the Ctek, better priced too. Definitely worth considering if you are looking for a new charger.
Well priced. Easy to set up. Instructions were clear. Packaging was very professionally done. My only criticism is they provided multiple power connectors for use in various parts of the world, which I thought was unfortunate because I only needed 1 out of the 5 or 6 provided. Just more waste. :(
Box says it'll charge up to 40 Ah battery, but maintains all sizes. Connected to a pair of 232 Ah 6V deep cycle RV batteries, which had been fully charged 2 months prior, and this unit couldn't top them off. It would just run endlessly before timing out and going into standby, and never reached the maintenance stage. I'm sure it would work fine on smaller batteries. I ended up getting the Noco 10, and it was up to the task, but only has 1 bank. The 25 wouldve been better, but CT doesn't sell the professional line, and the price is over $800.
For starters, the box is incredibly well packaged and ships with quite a few accessories, particularly with regards to AC plug options. Dare I say, too many? The charger is easy to mount to the wall, comes with long cords to practically mount anywhere, puts out consistent amperage when charging. When charging has completed, it automatically moves to a maintenance mode and slow-flashes a green light. Both banks work great and the small form factor is nice, too.#sweepstakes
