NOCO GENIUS2 2A Battery Charger
The GENIUS2 is a portable 6-volt and 12-volt battery charger, battery maintainer, trickle charger, and battery desulfator rated at 2-amp for lead-acid automotive, marine, and deep-cycle batteries, including flooded, gel, AGM, SLA, and maintenance-free, plus lithium-ion batteries. A...
What are you hoping to achieve? Is this for the starting battery or do you have a dual battery solution?
On the low end, a Battery Tender trickle charger will keep it from going flat. If you have a good battery, this simple solution will prevent a no-start situation, though your battery may not be in prime charge state. If it's just a lead acid starting battery then the alternator will do fine at topping it off when you drive again.
A Noco will provide better and more rapid charging. Something like a ProMariner will apply logic to condition the battery and you can select different battery profiles. I know the Noco claims to do the same, but in the research I did years ago the Noco just didn't have the power to do a good job at conditioning. I feel Noco spends on marketing and ProMariner on quality. Though you do pay for quality. I still have the ProMariner mounted to the wall in the garage and use if from time-to-time to top things off if needed. It's not used much since I went to RedArc, a BCDC 30 in the 200 and a Manager 30 in the Ram.
Back when I was still struggling with AGMs for house loads I used the ProMariner. At 24-amps has sufficient current to properly condition. The 2-amp Noco not so much.

After market apple car kills my main battery when the car is at the garage about 2 weeks. So that’s why I’m looking for battery charger to keep it alive.

Thank youNOCO GENIUS2 2A Battery Charger

I have not been impressed with my two NOCO chargers when it comes to their float voltage setting. I can use it to charge my AGM batteries on the AGM setting and the next morning I’m reading less than 13 volts and the charger is showing a pulsing green light meaning it’s in its maintenance stage. If I open the car door or something the voltage will drop enough to make the charger go through it’s charging cycle again. Neither of my noco chargers hold my odyssey batteries at the specified float voltage of around 13.5 volts
I have a BatteryMinder Model 12248 and in the AGM setting it holds the battery at 13.5 volts after it’s gone through a full charge cycle.
The main thing I like about the noco is the size and it’s so easy to setup and it remembers the last setting it was on when you unplugged it.

This NOCO unit, which is wired in rather than using alligator clips:
Amazon product ASIN B07W3QSMF9It works great for me, keeps my battery at 12.9V. I only drive my truck about every 10-14 days, so it gives me some peace of mind that my battery is in good shape for desert runs where I have my fridge going for a few days.

CTEK all the way - find them here: CTEK MXS 5.0
I've been using them for years with no problems.

This is the one I have in my car. Great option @hayden2203 if you want a permanent installation.

I use a Battery Tender unit rated at 4.5 amps, hardwired with SAE disconnect.

This NOCO has worked great for me on dual battery AGM's. It's bolted to Slee accessory mount. I connect an extension cord to connection under front bumper to top both off.
Part of what I don't love about Noco's is their proprietary connecter. I have SAE plugs installed on a couple cars for the tender. So I have the Noco SAE adapter. Just made another SAE to Anderson connecter, which should allow me to charge the new LiFePO4 house battery I just installed. Nice that the Noco can handle anything from flooded lead acid, to AGM, to Lithiums.
What's great about Anderson is I can just plug it into what would normally be an output port in the hatch area.

Another 2D fan here. Only had to drill two holes in plastic and install with zip ties, then one small relief cut under the core support plastic trim.
