Tips for Choosing the Best Car Battery Charger
Even the best car battery occasionally needs a charge. It may be hard to choose one battery charger that will suit your specific needs with so many out there. But fret not, we’re here to guide you. Here are some of the things you need to consider.
Identify your voltage needs – Depending on the voltage needs of your car, you can save up a ton of money. Say you only have a 12-volt car battery, then you’re much better of picking a 12-volt charger rather than a 6-volt since it can accommodate it in most cases. But if you need a versatile charger for not just your car but some other motors, you may opt for the 6 volts.
Amperage – Different batteries require different amperages. But fortunately, most car battery chargers today offer different amperages that will suit your needs. You just need to select which ones you will be using. Furthermore, there are certain chargers that charge your battery faster than others because of the number of amperages in them. But do be careful because fast doesn’t always mean safe.
Finding the right size – Battery chargers are getting lighter and portable as technology advances. And this is a good thing! For one, you don’t have to pick big battery chargers as heavy as the actual car batteries. And portable means you can bring it with you on the go so making them come in handy.
Manual or automatic – If you’re a mechanic, you might find it assuring to pick a manual charger. But for those that are new to cars, it will be easy to go fully automatic which means that there will be cases of overcharging. But even if you’re a mechanic or an auto geek, you might find that this feature is useful and convenient.
Smart Car Battery Chargers – With the advent of computers, everything is going automatic. They are not called smart chargers for no reason. This feature allows for a convenient and easy time as the charger itself will do the diagnostics for you. They can also prevent human errors that such as negative hookups or reversing the positive and negative hookups.
A Simple Guide to Charging Your Car Battery
You have the charger, but you don’t have a clue on how to charge the car. You wish it was as simple as charging your phone but it’s not. However, with this simple guide, we’ve got you covered!
- Safety first – Before anything, you want to make sure that you are working in a dry and well-lit area preferably in your garage. Then, make sure you wear protective glasses and gloves if you need to.
- Charging in your car or disconnecting it – Usually, most car chargers are easy enough to reach. But some need to be disconnected to be charged. When removing the battery, disconnect the negative terminal first then the positive.
- Place the battery – If you disconnected the battery from the car, place it in a flat surface away from the charger. You would want to keep the charger as far away as possible to prevent any damage or fire.
- Connecting properly – Start by making sure that the charger is off. Next, attach the black cable from the charger with the negative (-) sign on it to its corresponding terminal on the battery which has the same symbol. Then, attach the red cable which is the positive (+) to the positive terminal. Be sure to carefully check if you correctly put them in their respective terminals otherwise you risk damaging the battery.
- Starting the charge – Depending on the model of your charger, you may manually set the voltage or not. However, most batteries in the market now are easy to use just be sure to read the manual.
- Check if it works – Some modern batteries are equipped with LED displays that provide you all the things you will need to check such as the voltage, amps, charging status and error information. Usually, a car battery holds 48 amps and if you charge it at around 1amp/hour, it would take 12 hours to fully charge it.
