The GENIUS2D is the ultimate direct-mount onboard battery
charger, designed for under-the-hood charging. It acts as a
battery charger, maintainer, trickle charger, and desulfator,
making it the perfect solution for 12-volt lead-acid batteries
(up to 40 amp-hours), including AGM, gel, SLA, VRLA, flooded,
maintenance-free, deep-cycle, marine, and RV applications. It is
compatible with a vast array of vehicles, such as cars,
automobiles, lawn mowers, ATVs, UTVs, tractors, trucks, SUVs,
RVs, campers, trailers, boats, pickups, classic cars, and more,
including automotive brands like BMW, Mercedes-Benz, Porsche,
Bentley, Maserati, Lexus, Audi, Ford, Chevrolet, Corvette,
Cadillac, Prius, Toyota, Subaru, Nissan as well as lawn and
garden vehicles such as John Deere, Kubota, Toro and more. With
its rugged snap-fit mounting bracket and truss-head self-tapping
screws, installation is secure and effortless on most surfaces.
The GENIUS2D can charge batteries as low as 1 volt and even
offers Force Mode to manually charge completely dead batteries
(as low as zero volts). Its advanced monitoring system keeps your
battery fully charged without the risk of overcharging, while
precision pulse charging reverses sulfation and acid
stratification, restoring battery health and extending
performance. The package includes a 2A onboard charger
(120-240VAC), 24-inch AC and DC cables with eyelet terminals, a
mounting bracket, screws, and is backed by a three-year warranty.
Proudly designed in the USA, the GENIUS2D makes battery
maintenance simple, reliable, and hassle-free.
Review: Great product at a reasonable price - Installed on a Ford
Flex that is not driven much. Always needing charged. This
product worked great. Just unplug and go. Battery stays charged
and saves may battery and less work from the alternator.
Review: Keeps Batteries Charged Eliminates Inconvenience And
Aggravation - Few have the experience with batteries and charging
systems that I have. I'm 68 years old and a retired professional
mechanic who SPECIALIZED in batteries, starters, alternators and
electrical systems. This is what I did for a living and managed a
specialty battery store then my own shop that sold virtually
every battery for vehicles, diagnosed and installed all related
charging and starting system parts. The number one cause of
alternator failure is a LOW BATTERY. The alternator is NOT A
BATTERY CHARGER. It will not charge up a discharged low battery.
Many many folks have heard to jump start a dead battery and let
it run or drive the vehicle and it will charge up. I will NOT and
puts only a small surface charge on the battery. Essentially the
battery is 99% discharged. I have seven vehicles and only one
doesn't have a maintainer on it. That vehicle is a
non-computerized F-100 Ford. However, my Winnebago RV, 2023 ATV,
Honda Sabre M/C, Honda Fit, Ford Ranger and my Dodge Caravan all
have maintainers on them. Computerized vehicles that are not used
daily that sit for any amount of time get low on charge. That's a
fact. As a professional, I can tell you that if you want to do
yourself a HUGE favor, use charger maintainers. I use the Noco
Genius 1 on many things I own and this Genius 2 now just
installed on my Honda Fit. Little is worse than going out to a
low or dead batteries. Just as bad is starting a car with a low
battery then driving it. It's very bad on the charging system and
related components. These Noco products feature wide
compatibility, are highly functional and are very simple to use.
It really is a plug in and forget product that is highly useful.
You just have to remember to disconnect it when you use the
vehicle.
