Speaker 1: Today, we're taking a look at the Noco Genius mini-onboard batter charger. This onboard battery charger is designed for charging and maintaining, two 12-volt marine starter deep cycle batteries.So, it's a two bank charger. Mounts directly to your application, like your boat, trolling motor, generator, electric vehicle, or any type of industrial equipment. It's ideal for batteries up to 120 amp hours or, 12-volt batteries. It simply, converts AC power into safe, DC power for battery charging.Charging the amperage is, eight amps. That's four amps per bank.

It's also, designed to monitor battery activity for safe, fast, and efficient charging of lead acid batteries such as, wet, gel, AGM, EFB, and maintenance free batteries without the worry of overcharging.Now, this unit has smart technology built into it. So, it begins charging when needed and, it allows for continuous operation without supervision. It is a 100% sealed so, it does have waterproof rating to it and it is fully submersible. It's also, salt water tested to combat corrosion.It's a nice design. The mount holes are already pre-drilled into it.

And it does come with installation hardware. Located right here are the charging LEDs so, this allows you to visually see the charging status. They'll light up red when it's in the charge mode. And then, they'll turn green when charging is complete. Also, it has the air LED to notify you when an air condition occurs or exists.Internally, it has a built-in battery diesel fader, which is designed to rejuvenate under-preforming batteries.

So, it recovers deeply discharged batteries. And, the unit is ignition protected. It's a non-igniting and temperature . Excuse me. It's a non-igniting and temperature controlled onboard battery charger, which allows for safe, and worry free operation.It's really simple.

You have your AC connector here, three prong power chord. And then, it converts it to DC power. Each one of these connectors, does have built in fuse, so it's fuse protected with a 15 amp fuse. And then, you have your black terminal for your negative post. Red terminal for your positive post.Also, these feature a lay flat design, so they don't take up much room once they're connected. And, they are designed to fit over a 3/8 inch diameter post. Few measurements to go over with you real quick. We're going to take measurements of the actual, unit here.So, at the widest portion, I've got a measurement of seven and 7/8 of an inch, by five and half inches, by two and one quarter inches. The mount holes on the unit, side-to-side this direction. They're separated on center by six and half inches. Going this direction, they're separated on center by four and 5/16 inches.That's going to do it for today's look at the Noco Genius mini-onboard battery charger.

  • Can Blue Ox Patriot Supplemental Braking System be Charged with AC Power
  • Since the Blue Ox Patriot part # BRK2019 is designed for use in a vehicle it's charging system requires 12 volts of power and would not charge if connected directly to an AC power source like you described. You'd need an adapter to convert the AC power to DC like the NOCO Genius Mini On-Board Battery Charger # 329-GENM2 and you'd be able to charge the Patriot in your house.

  • The NOCO Genius Mini On-Board Battery Charger - AC to DC - 2-Bank - 12V - 8 Amp # 329-GENM2 is showing that your batteries are not being recognized by the charger.

  • Can NOCO Genius Mini On-Board Battery Charger be Used to Charge Deep Cycle Battery
