When a vehicle is in storage, the batteries gradually lose power. Use a battery maintainer to keep your car’s battery alive. Nothing is worse than finding your car battery drained as you prepare for a road trip or are simply running to the store. Yes, you could always ask a neighbor to jump-start your dead battery and get you running again, but they might not be home. Owning your battery charger is crucial because it’s not the best idea to rely on the possibility that someone may be around.
Using a battery maintainer that ends up harming and reducing the lifespan of your car batteries is not something you want to do. Because of this, we took the time to find, identify, and evaluate the top five battery maintainers available.
So, let’s dive in!

NOCO GENIUS10 Automatic Smart Charger and Battery Maintainer
Having a maintainer with as many built-in safety mechanisms as possible is also beneficial. It is challenging to surpass the NOCO GENIUS10 in that regard. The GENIUS10, an upgraded, more compact, more powerful version of NOCO’s G7200, features built-in safeguards against overheating, overcharging, short-circuiting, and open-circuit mishaps. Additionally, it is reverse polarity protected and spark-proof, so attaching the wires to the battery terminals in the wrong order won’t harm them. All of these functions make sure that the GENIUS10 protects not only you but also your battery, vehicle, and self.
The use of a car battery maintainer carries some danger. You run the risk of getting shocked whenever you handle electricity, so you should always carefully follow the directions that come with any automatic battery charger or maintainer you use. The GENIUS10 is not only secure but also has a lot of power. Any size of a car battery can be maintained thanks to the 10 amps of charging power.
DieHard 71219
It’s hardly surprising that DieHard, one of the most well-known brands in the battery industry, also produces a superb battery maintainer. This DieHard 71219 Shelf Smart Battery Charger and Maintainer offers incredible value and performance.
You can select from a variety of charging amps, but for battery maintenance, we advise sticking with the 2-amp model. Regardless of the model you select, you will receive incredibly strong cables for a secure connection, and the chargers themselves come with overcharging and reverse polarity protection features.
It’s easy to understand why this smart charger and maintainer came in at the top of our list when you consider its portability, durability, and lightweight. The absence of settings designed for gel or AGM batteries is the only serious issue with this battery charger and maintainer.
There is no disputing that while the charger may charge certain battery types as well, it doesn’t perform as well as an AGM or gel battery-specific charger. You won’t, however, find a better match than this DieHard battery charger for the majority of residential garages!
Battery Tender Plus Battery Charger and Maintainer
When a battery is being maintained, the Battery Tender Plus continuously gives 1.25 amps of electricity until the battery is full, at which point it enters “float” mode. This indicates that it stops supplying electricity as soon as the battery stops being fully charged owing to typical discharge. When that happens, the Battery Tender Plus brings it back to full and then turns off the power until another discharge is placed.
One of the most well-known names in the battery charging and maintenance industries is Deltran’s Battery Tender brand, and for good reason—the company’s products are frequently hailed as some of the best available. The Battery Tender Plus, a charger, and maintainer that also won the top spot overall on our Cars’ list of the finest chargers, is a good example.
The Battery Tender Plus is a flexible option even if it doesn’t function with deep-cycle batteries. Instead, it can charge and maintain lead-acid, flooded, and sealed maintenance-free batteries. The charging feature may maintain cars, SUVs, and other larger vehicles, while it is mostly advised for those with smaller engines (such as motorcycles, ATVs, and jet skis).
Optima Digital 400 Battery Maintainer
If you use Optima AGM batteries, which are among the best on the market, you should pair them with this excellent charger. Look no further than the Optima Digital 400 if you’re seeking for the best AGM battery maintainer. Your AGM batteries can be maintained and recharged with it, in addition to normal lead-acid and gel batteries.
The hooks make it simple to hang on the hood of your car while you charge everything, and the LCD screen is very easy to see. The built-in battery health mode, however, really sets this AGM battery charger apart from the competition.
Any seasoned mechanic will tell you that using a conventional battery charger with an AGM battery won’t produce the desired results. So, it is preferable to purchase an AGM-specific battery charger and maintainer if you frequently operate with AGM batteries or solely use AGM batteries in your car.
To maximize the life of your battery, this mode automatically performs a diagnostic evaluation of its condition. This diagnostic test is carried out by the Optima Digital 400 throughout the whole charging and maintenance cycle, hence extending the battery’s lifespan. The Optima Digital 400’s pricing is its one serious flaw, yet it isn’t too pricey either. However, it’s advisable to save some money and use a conventional battery charger and maintainer if you don’t intend to charge or maintain AGM batteries.
Schumacher SC1355 Automatic Battery Maintainer
The Schumacher SC1355 is a dependable model from a reputable company for maintaining and charging car batteries. However, one feature that sets apart this Schumacher battery maintainer is the automated amperage adjustment that ensures your battery is maintained effectively, up to a maximum of 1.5 amps. It also switches automatically into float charger mode after the task is over, much like other automobile battery maintainers do. As a result, your battery will always receive care that is customized for it.
The strength of your battery charger determines how quickly your car battery charges (even during extended plugged-in maintenance). This is often expressed in amperes. Your charger is more powerful (and thus more expensive) the higher the amperage.
The Schumacher SC1355 also functions as a deep-cycle battery charger and lead-acid battery maintainer, which is an added benefit. It can therefore be used to recharge the battery of a boat in addition to a car or other smaller vehicle.

What is better a battery maintainer or a trickle charger?
Battery maintainers can be left plugged in whereas trickle chargers should be unplugged after they have finished charging. Keep in mind that while every battery maintainer is “smart,” it won’t charge a battery that is already full.
How do I choose a battery maintainer?
Generally speaking, your battery charger should be 10% to 20% of the battery’s Ah rating. For instance, a 10 Amp charger is the very minimum needed for a 100 Ah battery. You should keep the charger size to within 30% of the entire capacity to avoid overcharging.
How long will a car battery last on a maintainer?
The majority of car batteries in good condition last for at least two weeks before needing to be recharged by starting the vehicle and driving. However, you should still start your automobile once a week to replenish the 12-volt battery if you won’t be using it for a while for any reason.
Can you overcharge a battery with a maintainer?
A battery maintainer can be connected to a battery forever without the risk of overcharging, unlike normal and trickle chargers.
Can you leave a battery maintainer on overnight?
Battery life and dependability can consequently be extended by proper and consistent use of battery chargers. Even if using a high-quality charger eliminates the possibility of overcharging, the battery shouldn’t be left attached to the charger for longer than 24 hours.
Can you start a car with a battery maintainer plugged in?
Yes, but keeping it connected is unnecessary. When starting, it is safer to take the charger out of the battery. By the time you are starting your automobile, the battery has (or should have) reached its full charge.
What’s the difference between a battery tender and a trickle charger?
A trickle charger continuously delivers a consistent current. It is unaware of the battery’s state of charge or discharge. An intelligent battery tenders. Only when the battery requires charging will it start to recharge.
