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.

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.
