Not all cars are intended to be driven daily. If you own a special vehicle, such as a classic or sports car, you can probably keep it hidden somewhere until you feel like taking it for a spin. The problem is that you can experience the ultimate mood killer in this situation. This is that the car has not started because the battery died because it was idle for too long.
There is a simple solution to this. It is a car battery maintainer, also known as a trickle charger. They are designed to provide a small amount of power to the battery, and are only enough to allow the juice to flow when using it again. We rounded up some of the best battery maintainers on the market for use in cars, motorcycles and more.
Battery Soft Plus 12V 1.25-AMP Car and Motorcycle Battery Charger and Maintenance
This universal battery maintainer works with all types of starter batteries, from vehicles to lawn mowers. However, it is not designed to charge dead cars’ batteries. It works in four steps. First, determine the current battery charge level. After that, start charging as needed, and the strength decreases as it approaches full charge. Once fully charged, it automatically switches to low ampere maintenance mode to keep the battery at optimal power without overcharging.
It’s easy to use. Simply connect, connect to the battery and make the magic work. Red and green LED lights can signal the current status of the battery at all stages.
Important specifications:
- Charging current: 1.25 amps
- What makes it special: Adjusts to all kinds of starter batteries
NoCo Genius10 10A Smart Car Battery Charger and Battery Maintenance
The Noco Genius10 maintainer can also charge dead batteries. It automatically detects sulfur deposits and acid layering in the battery, and is designed to repair and charge to optimal conditions, so it does more than that. There is also an integrated thermal sensor that detects the temperature on the outside and avoids overcharging or overcharging depending on the cold or heat outside. This means it can be left in place for months and adapts based on changing weather.
It also works with a small 6-volt battery, allowing you to charge or maintain your electric scooter, golf cart, e-bike, and even vintage cars and motorcycles.
Important specifications:
- Charging current: 10 amps
- Voltage : 6 volts or 12 volts
- What makes it special: Restore your battery and keep it in perfect condition for any season
CTEK 40-206 MXS 5.0 Fully Automatic 4.3-AMP Battery Charger and Maintenance
If simplicity and ease of use are your priority, CTEK battery maintainers offer without compromising quality. It’s completely automatic, so simply plug it into the battery and it automatically enters an 8-stage charging and maintenance program. It is also light and compact enough to be easily stored in a trunk or garage.
If the battery needs to be charged or maintained in difficult outdoor conditions, it’s a great tool as it is designed to be completely splashed and dust-resistant. Its “set and forgetting” feature is ideal if you plan to store your car for several months. This is because it automatically provides the right amount of power to keep you charged.
Important specifications:
- Charging current: 4.3 amps
- What makes it special: Compact, lightweight and easy to use
Schumacher Electric Vehicle Battery Charger and Maintenance SC1280
The Schumacher Electric Heavy-Duty Battery charger and maintainer supports batteries of up to 800 cold crank amplifiers, making it suitable for vehicles with large engines such as large SUVs, pickup trucks, high-performance vehicles, and diesel engines. It supplies up to 15 amps to quickly charge dead batteries, and automatically returns to 2-3 amps to maintain them for the long term, making them highly adaptable to your specific needs.
In addition to charging and maintaining, you can also test the current state of the battery to desulfurize it. Easy to use and has built-in reverse hookup protection so if you confuse positive and negative when connecting clamps, it can protect your car’s electrical system.
Important specifications:
- Charging current: 15 amps
- Voltage : 6 volts or 12 volts
- What makes it special: Large engine and diesel capacity
How to choose the right battery maintainer for your car
After reading the product description and specifications, you probably have a rough idea of what can and cannot be done based on the characteristics of the battery maintainer. Below are some specific steps that will help you choose the right one for your car.
Make sure the maintainer is compatible with your car battery
There are three main types of car batteries: lead acid, absorbent glass mats and lithium. Check the battery label and check the type you have in your car. For example, many hybrids and plug-in hybrids use lithium batteries, and many typical battery maintainers are not designed to work with them.
Determine the charger output on the right
If you think that the battery needs to be charged as well, the battery maintainer’s charger output should be at least 10% of the battery’s total amplifier time rating. For example, if your car has a 50 amp battery, you need to look for a maintainer that can deliver at least 5 amps. If you’re more interested in maintaining a fully charged battery, a low amp maintainer will probably do a good job.
Consider the length of the cord
This may sound trivial, but determining the length of the code required by a battery maintainer is a major step. Imagine how frustrating it must be to start preparing your sports car for winter storage and make sure your garage outlet is too far. Extension cords may work, but it is not a good idea to use one and leave it unsupervised for weeks or months at a time.
