It’s a common question: can you connect a battery charger to a car battery? The answer is yes, but there are a few things you need to know first. For one, make sure the charger is designed for automotive use.
Some chargers are only meant for household batteries and could damage your car battery. Second, be aware of the polarity of the connection. Most car batteries have color-coded terminals (red for positive, black for negative) to help you avoid connecting the wrong way.
Finally, don’t leave the charger all night unattended while it’s connected to your battery; this could cause damage or even start a fire. If you follow these simple guidelines, charging your car battery with a charger is safe and easy.
- Open the hood of your car and locate the battery;
- Clean the terminals on the battery with a wire brush to ensure good contact where AutoZone offers a variety of battery terminals;
- Connect one end of the positive (red) charger cable to the positive terminal on the battery, and connect one end of the negative (black) charger cable to the negative terminal on the battery;
- Plug in the charger and set it to deliver a slow charge overnight or for at least eight hours otherwise battery drains so fast;
What are the Benefits of Connecting a Battery Charger to a Car Battery?
When a car battery is not being used, it will slowly lose its charge. This is why it’s important to regularly check the level of charge in your battery and top it up if necessary. One way to do this is by connecting a battery charger to your car battery.
There are several benefits of doing this:
|You can avoid potential problems caused by a flat battery||If your battery completely runs out of charge, you may find that your car won’t start. This can be extremely frustrating – and potentially expensive if you need to call out a tow truck or roadside assistance service. By keeping your battery charged, you can help avoid this type of problem.|
|You can prolong the life of your battery||When a battery is regularly topped up with power, it will last longer than one that is only used occasionally and allowed to run down completely each time. This means that you won’t have to replace your car battery as often, which can save you money in the long run.|
|You can improve the performance of your vehicle’s electrical system overall||A well-maintained and properly functioning electrical system is essential for the smooth running of any vehicle – so keeping everything in good condition will help keep your car running smoothly (and may even improve fuel efficiency).|
