5 Pro Tips: How to Safely Use a Battery Charger {2023}

A dead car battery is a common issue, particularly during the colder months of winter, making it important for everyone to know how to use a battery charger, and how to be able to do so in a safe manner.

Car battery chargers slowly recharge the battery of a vehicle and are essential for car owners. If it is difficult to start your car in the morning, or your battery is dying, then it is a good idea to always keep a portable battery charger in your vehicle just in case.

How to Safely Use a Battery Charger

It is important to always make use of safety goggles when charging up batteries as there is always a chance, regardless of how slim, that a battery could explode upon charging.

Car batteries contain chemicals that result in the production of hydrogen gas when used. This gas is highly volatile and can explode in certain conditions, which can result in serious injuries.

It is therefore very important to know how to safely use a battery charger.

The battery charger

The first step to safely using a battery charger is to purchase a battery charger. There are different types of battery chargers so it is a good idea to know your specific model before you use it. Read all the instructions carefully and make sure you fully understand the way your charger works and the purpose of every button, dial, or reading.

Connecting the charger

Once you have familiarized yourself with the battery charger, the next step is to connect it to the battery of your vehicle. The battery can be charged while inside the vehicle or after it has been removed. The positive (red) clamp should be attached to the battery’s positive post, which will have a + sign on it. The next step is to attach the negative (black) clamp to the battery’s negative post, which will be marked by a – sign.

Setting the battery charger

You will then need to set the charger’s volts and amps. If you intend to slowly trickle charge the car battery then it should be set to a lower amperage than would be the case if you were attempting to quickly start your vehicle. If there is time to spare trickle charging is the best charging method, though higher amperage is required when the aim is to start a car as quickly as possible.

Plug and charge

The charger can then be plugged in and left to do its job. It may be possible to set a particular period of time in which the charger can work, or it may shut itself off automatically when charging is complete. The charger should not be moved or the cord played with during this time.


After the battery has been fully charged the charger can be turned off and then unplugged from the wall. The cables should then be disconnected in the opposite order to the way in which they were attached, with the negative clamp disconnected first followed by the positive clamp. At this point, the battery should be safely charged and the vehicle ready to go.

Knowing how to safely use a battery charger is crucial for all car owners.
