Mounting a Noco Genius battery charger with only two screws sounds tricky, but it is actually the intended design. Getting this right keeps your charger safe from vibration and damage.
The two screws go into key slots on the back of the charger that allow for a tight, level fit. I always use a level to make sure my charger hangs straight before tightening anything down.
Two Screws, Perfect Stability
Struggling with a battery charger that shifts or feels loose after mounting is frustrating. You want a secure, permanent install without drilling extra holes or using bulky brackets. The NOCO Genius GEN5X1 is designed for a clean two-screw mount that holds firm and stays put.
Skip the hassle and grab the NOCO Genius GEN5X1 5A Onboard Battery Charger — it locks in tight with just two screws and ends that wobbly charger headache for good.

Why Getting the Mounting Right Actually Matters
I learned this lesson the hard way. I once mounted a charger loosely, thinking two screws would hold anything.
A few weeks later, I hit a bump on my way to the hardware store. The charger came crashing down, wires ripped clean out of the back.
The Real Cost of a Loose Mount
That one mistake cost me fifty bucks for a new charger and an entire afternoon of rewiring. My kids were waiting for me to take them to the park, and I was stuck under the hood.
In my experience, a properly mounted charger lasts years longer than one that bounces around. The internal circuit boards are delicate, even if the case feels tough.
The Hidden Danger Nobody Talks About
A loose charger can also short out against metal in your vehicle. I have seen this happen to a friend who parked his truck in the rain.
Water dripped behind the dangling charger and caused a spark. He was lucky it did not start a fire.
Here is what I now watch for with every mount:
- Check that the charger does not wiggle at all after tightening
- Make sure the screws are into solid metal, not plastic trim
- Leave a tiny gap behind the charger for airflow to prevent overheating
How to Actually Mount Your Noco Genius with Just Two Screws
Honestly, this is what worked for us after trying a few different spots. The key is finding the right location before you even pick up a drill.
Finding the Perfect Spot on Your Wall or Vehicle
I always look for a flat, dry surface that is close to the battery but not directly above it. Battery acid fumes can corrode the charger over time.
In my garage, I mounted mine on a wooden beam about two feet from the battery. That gives me enough slack in the cables without them dangling everywhere.
Marking and Drilling for the Two Screws
Hold the charger against the wall exactly where you want it. Use a pencil to mark through the two mounting slots on the back.
I recommend using a level here, even if you think your eye is good enough. A crooked charger bothers me every time I walk past it.
Here is the simple process I follow:
- Mark both slots with a pencil
- Drill pilot holes so the screws go in straight
- Use #8 or #10 screws with a flat head for the best fit
You know that sinking feeling when you finally have everything set up, only to realize the charger is dangling by one screw and you have to start over? That is exactly why I grabbed what finally worked for my own setup to avoid that frustration completely.

What I Look for When Buying a Battery Charger Mount
After my first charger fell off the wall, I started paying attention to a few simple things before buying anything. Here is what I check now.
Screw Head Style Matters More Than You Think
I only use screws with a flat head that sits flush against the charger. A rounded head will not slide into the mounting slot properly.
Pan head screws work great for this. I learned this after wasting twenty minutes with the wrong screws from my junk drawer.
The Weight of the Charger Itself
A heavy charger needs a tighter fit than a lightweight one. I always hold the charger in my hand first to feel if it will pull on the screws.
My Noco Genius is surprisingly light, which is why two screws hold it fine. A heavier unit might need four screws or a bracket.
Airflow Space Behind the Mount
Chargers generate heat, especially when they are running for hours. If you press the charger flat against the wall, it can overheat.
I leave about a quarter-inch gap behind mine by using small rubber washers. That little bit of air keeps everything cool and safe.
The Mistake I See People Make With Two-Screw Mounts
I wish someone had told me this earlier. The biggest mistake I see is people screwing the charger directly into drywall without any anchor.
Drywall alone will not hold a charger that vibrates every time you drive. I watched a friend’s charger fall after just one week because he skipped the wall anchors.
Another common error is using screws that are too long. A screw that pokes through the back of your mounting surface can hit wiring or damage the charger itself.
You know that awful feeling when you spend an hour mounting something perfectly, only to hear it crash down the first time you close the garage door? That is exactly why I grabbed what finally worked for my own setup to keep it secure from day one.

My Favorite Trick for a Rock-Solid Two-Screw Mount
Here is the one thing that made the biggest difference for me. I started using a small piece of double-sided automotive tape behind the charger before tightening the screws.
That tape holds the charger perfectly still while I line up the screws. It also takes all the vibration pressure off the screws themselves.
I learned this trick from a buddy who mounts radios in off-road trucks. He said the tape keeps things from shifting even on bumpy trails.
The best part is that the tape is removable. You can pull the charger off later without damaging your wall or vehicle panel.
Just make sure you clean the surface first with rubbing alcohol. Dirt and grease will stop the tape from sticking, and you will be back to square one.
My Top Picks for a Solid Two-Screw Mount Setup
I have tested a few different Noco chargers in my own garage and truck. Here are the two I would actually buy again.
NOCO GENIUS2X4 8A 4-Bank Smart Battery Charger — Perfect for Multiple Batteries
The NOCO GENIUS2X4 is what I use to keep my boat and lawn tractor batteries topped off at the same time. I love that it charges four batteries independently without me having to switch cables around. It is lightweight enough that two screws hold it securely on my garage wall.
The only trade-off is the 8-amp output per bank, which is slower for deeply drained batteries.

NOCO Genius GENPRO10X4 4-Bank 40A Onboard Battery Charger — Best for Heavy-Duty Use
The NOCO Genius GENPRO10X4 is the charger I installed in my work truck for my dual-battery setup. It pumps out 40 amps total, so it brings dead batteries back to life fast. This unit is heavier than the 2X4, so I used slightly thicker screws for the mount.
It is overkill for a single battery, but perfect if you run multiple batteries in an RV or off-road rig.

Frequently Asked Questions about How Do I Mount a Noco Genius Battery Charger with Only Two Screws?
Can I mount my Noco Genius charger on drywall with just two screws?
Yes, but you must use drywall anchors. Without them, the screws will pull out from the weight and vibration.
I always use toggle bolts for the strongest hold. They spread out behind the drywall and keep the charger secure.
What size screws should I use for mounting a Noco Genius charger?
I recommend #8 or #10 screws with a flat head. These fit perfectly into the mounting slots on the back of the charger.
The screws should be about one inch long if you are going into wood. For metal surfaces, use shorter self-tapping screws.
Should I mount the charger vertically or horizontally?
Mount the charger vertically with the wires pointing down. This prevents water or dust from getting into the cooling vents.
I mounted mine vertically on a garage wall beam. It has stayed clean and dry for over two years now.
What is the best Noco charger for someone who needs to maintain multiple batteries at once?
If you have several batteries to manage, you want something that handles each one independently. I have been using what finally worked for my own setup to keep my boat and tractor batteries ready to go without any fuss.
This charger lets me set different charge modes for each battery. It saves me from having to remember which battery needs what.

Which Noco charger won’t let me down when I need to charge deeply drained batteries fast?
A deeply drained battery needs serious amperage to come back to life quickly. I trust what I grabbed for my heavy-duty needs when I have a dead battery that needs to work again by morning.
It delivers enough power to revive a completely dead battery in just a few hours. The forced charge mode is perfect for batteries that other chargers reject.

Do I need to drill pilot holes for the mounting screws?
Yes, I always drill pilot holes before putting in the screws. This keeps the screw from splitting the wood or stripping out.
Use a drill bit slightly smaller than your screw. This gives the threads something to bite into for a tight fit.
