 Best Trickle Charger for car battery 

Buying Guide

There are many trickle chargers for cars available in the market that it becomes a bit difficult to choose the best one for you. These battery chargers are made in different designs to fit different situations. As far as your budget is essential, it is still vital to take note of some features before buying one.

Battery Voltage

Before settling on a particular trickle charger, it is crucial to know your battery voltage. This is because some chargers are manufactured to suit either a 6 volt or a 12-volt battery. Hence, you need to know how compatible your battery will be with the charger.

Battery Type

Battery charger with trickle charge function is made to support different battery types. Some may work well with acid-lead batteries or AGM batteries or even WET batteries. Therefore, you should check the charger's compatibility with your battery before buying it. Also, if you use an incompatible charger, it may damage your battery.


Trickle battery chargers come with different purposes, such as maintaining your battery while charging it either fast or slow. Therefore, it is necessary to know the features of the charger before buying. Some battery chargers that double as a battery maintainer may reduce delivery based on charging performance. Hence, you should know what you need in a charger before buying.


This is one factor we all look out for before buying a product. Hence, it is only reasonable if you look for a durable battery charger. To get a long-lasting trickle charger, you must get one that has an inbuilt cooling fan. This will help you to avoid overheating and excess use of it.


Some battery maintainers come with safety features for both you as well as your battery. Some features such as anti-shock, voltage regulators, and clamps work together to improve the safety of battery chargers.

Additionally, some chargers check if there is a reversed polarity on the connectors of their batteries. Therefore, you should check the features of the battery charger so that you will know the exact functionality.


The health of our batteries is one major factor to consider before buying a charger. Some maintainers diagnose the problems with your battery.

One major problem it diagnoses is the inability of your cell to retain a full charge. Therefore, if you need a diagnostic charger, then it is vital to know the features before buying one.

Engine size

The size of your engine determines the size of your battery and the capacity of the battery charger. A big engine will require a charger with high capacity. Therefore, ensure that you check the size of your engine and capacity of the trickle charger before buying one.

Type of Charger

Apart from the different models of battery chargers, there are two types of battery chargers. The Dumb and Smart battery chargers.

  • Dumb Style: This is the traditional type of battery charger that can charge any size of the battery. Although they are cheaper than the smart style, they may lack most of the advanced features that the smart form possesses.
  • Smart Style: Smart style is more expensive than the dumb form but comes with more advanced technology. This allows you to plug your battery and leave it for a long time after charging it without fear of damaging your battery. They possess inbuilt monitors that can detect the status of your battery as well as the charge level.

What is the difference between auto Trickle Chargers and Battery Maintainers?

Automotive Trickle Chargers are used for a long charge. Sometimes, we may want to plug the battery to the charger while attending to other duties. As a result, we leave the battery and charger unattended, and when this is the case with regular chargers, the battery starts losing power or discharging.

However, this can be checked by using a automobile trickle charger as these chargers will charge continuously after the battery is full, in a small amount of power. Therefore, a trickle charger works to keep your battery full all the time.

On the other side, a battery maintainer will automatically go off as soon as your battery is full and then monitors your battery until it drops to a certain level. When this occurs, it will automatically resume charging until the battery is complete once more. Hence, this saves your battery life and reduces reverse discharge. 

How to Connect a Trickle Charger to a Car Battery?

If you do not know how to use a trickle charger or how to trickle charge a car battery, don’t be bothered because it is as easy as ABC. Many times, some of these car trickle chargers come with instructions that make it easier to set up and use it effectively. However, we have compiled a step by step process to let you set it up quickly.

  • Run a checkup: It is crucial to be sure about you and your battery's safety before connecting your battery to a trickle charger. Park your vehicle in a well-ventilated space. This is because trickle charging car battery releases an amount of hydrogen gas that may cause a battery explosion if the car is parked in a tight area. Ensure that you turn off the ignition of your vehicle and remove your car keys. Also, you should find an appropriate place to fasten the trickle charger's negative terminal.
  • NB: Using your car battery’s negative terminal could result in an explosion. Therefore, do not use it when trying to trickle charge.
  • Connect the wires: As soon as you complete the above step, the next step is coupling the cables. However, before you start, you must fix the ampere and voltage of the trickle charger to suit your car's battery. When you do this, locate the alligator clips, the red and black clips. You should connect the red clip (positive wire) to your battery's positive terminal and the black clip (negative cable) to the negative terminal. 
  • NB: Avoid touching the wires while they are plugged in as they could shock you. Therefore, stay a long way off from the cables.

Turn the charger on: Before turning the charger on, go through the manual thoroughly to ensure that you did not miss any step and that you connected the wires adequately. When you are sure, you can turn the charger on.
