Don’t you feel annoyed when your car doesn’t start? Batteries that are not charged can be quite annoying at times. Maybe you want to go to your summertime lodge for the weekend and your Jeep won’t start. Or it’s time to mow the lawn, and your lawnmower is out of its battery. Or maybe it’s time to go on a bike ride, and your favorite one won’t start.
All of these are battery problems. They are out of charge. That is why you need to have a battery charger handy at all times.
There are different charges for different types of batteries. Not all chargers can charge every vehicle’s battery. Some charge small vehicles, and other charge heavy vehicle batteries. Some battery chargers don’t support all battery types. So it is better if you know about them before buying one.
Here we have gathered all the best 12 volt battery chargers available on the market right now. They start from bike battery chargers and go to personal plane or RV chargers.
Top 5 Best 12 Volt Battery Chargers for Bikes, Cars, RVs, Tractors, and Personal Plane
1. NOCO GENIUS1, 1-Amp Fully-Automatic Smart Charger
If you are talking about battery chargers, portability should be your priority. Today, you no longer need to wait for someone to help you get going.
The NOCO Genius1 is an automatic car charger that is steady, stable, and reliable. It is cost-efficient and does what it says. The best part of NOCO Genius1 is that it can charge all types of batteries, be it AGM, Lithium-ion, or deep cycle. It can charge both 6 volts and 12volt batteries.
It has the function to trickle charge and keep your battery charged for a long period of inactivity. The inbuilt temperature sensor makes the necessary adjustments to make the 1-amp charge distribute accordingly. Also, the temperature sensor understands the climate and provides the correct charge accordingly. So there is no fear of undercharging or overcharging.
Another fine feature of the NOCO Genius1 is it can revive a completely dead battery. Although it is an automatic charger, it has a Force Mode which acts as a manual charger. So it can do a continuous charge to a dead battery that has zero battery voltage without any trouble at all.
Although it is a battery charger, it only charges batteries up to 30amps. Over that, it can’t charge. So it is good for bikes, lawnmowers, and batteries that are not over 30 amps. So be sure to check your battery amps before you order this product. Otherwise, your battery will charge slowly like a sloth.
If you check the manual, it lets you know how long it takes a particular vehicle battery to charge. With NOCO Genius1, it takes a motorcycle battery 15 hours to charge in 20 amp/hr, a lawnmower battery 30 hours in 40 amp/hr, a full-size car battery takes 60 hours at 80 amp/hr, and a truck battery 75 hours on 100 amp/hr. So it is wise to use a high amp charger than a Genius1 to charge larger batteries.
- Automatic detection, automatic charging, and turn off.
- Temperature control built-in.
- Great value for money.
- Not made for all cars and obviously not trucks.
2. TowerTop 2/10/25A 12V Smart Battery Charger/Maintainer
This charger from TowerTop does what it says and more. It can charge many types of batteries. It has automatic battery detection so it can charge at the appropriate amp rate. GEL, AGM, and STD batteries can be charged with this. After the battery is fully charged, it detects it and turns it over by itself. So you don’t have to worry about overcharging and heating the battery.
You can even view the battery charging level from its LCD, which is a nice touch from the manufacturer. You can also test or view your battery’s current charge with this charger. But to do that, you have to plug the charger into the power socket. Otherwise, the LCD won’t turn on.
One of the nicest features of this TowerTop smart charger is that it can start your car within 120 seconds.
It works as a battery maintainer too. It has a 7 level charging step for every cell of your battery. So you don’t have to worry about your battery getting overheated or facing any trouble while charging.
There is a float function that lets your battery sit on standby without losing any power or charging. It is a sweet little function to keep your battery full at all times.
It doesn’t charge dead or frozen batteries. Meaning, if our battery charge is below 4V, then the charger won’t be able to charge it.
Although it is a smart charger, it is not automatic. So it forgets its settings if there is a power break. You will have to set it once again the configuration you want to charge. For this inconvenience, it is not a wise choice if you are thinking of keeping it in your winter cabin to maintain your battery. Because you might come back to a fully drained and uncharged battery if there is a power surge. But it performs well under supervision.
- Keeps the battery on a full charge without charging or losing power.
- Supports various types of batteries.
- Charges every cell individually before moving to another one.
