NOCO Genius 2D Onboard Battery Charger

She stables in the garage, wild and untamed, ready to bust out. But rarely allowed to flex her muscles, and never in wet or wintery weather. And because there’s a slight (but normal) parasitic draw of her electronics (somewhere around 25-40-milliamp), I installed the NOCO Genius 2D onboard, direct mount battery charger, and maintainer under her feather-weight aluminum hood.

The NOCO Genius 2D is a 115 Volt x 12 Volt 2 Amp fused and completely automatic tender that “features an integrated thermal sensor that automatically monitors and adjusts the charging cycle based on fluctuations of ambient temperature.” Advanced diagnostics keep you informed about your battery’s condition: temperature, reverse polarity, bad battery, battery short, and high voltage. That’s a bunch in a little package for less than forty-bucks.

Using 8×1/2″ flathead countersunk screws, I secured the included mounting bracket to an L-bracket and wrapped the bracket assembly in black electrical tape to match the underhood blackness, then bolted it to a spare mounting hole on the under-hood fuse box with a self-locking nut.

The positive lead I fastened to the aft terminal on the terminal block that runs directly to the battery’s positive terminal. The negative lead I secured to an existing ground on the strut housing. You can, if you prefer, connect the Genius 2D directly to the battery. For aesthetic and routing reasons, I opted not to.

With the Genius 2D in place, I used black wire loom and wire ties to complete the professional look.

Solid green shows the battery at 100%. And slow pulsing green indicates an ongoing optimization. It all works to extend battery life without the risk of overcharging your battery. Like the innovative folks at NOCO say, it’s a more powerful, compact, and incredibly smart device.

It’s backed by a 3-year hassle-free warranty.
