Choosing the Best Car Battery Charger | A Definitive Buyer’s Guide
A car battery needs to be constantly recharged if you want to ensure a smooth ride. When you drive, the alternator kicks in and recharges the battery. However, leave the vehicle on idle for days, and you will find yourself a dead battery.
This is immensely frustrating because recharging a completely out-of-juice battery is time-consuming. If you want to get your vehicle up and running again, you need to charge the battery just enough to get the engine going.
Now, whenever you buy a car, it’s a good idea to buy a car battery charger to go along with it. If you are an auto enthusiast, it won’t be that hard to find the right auto battery charger.
Not all of us are car enthusiasts. If you are like me and want a simple guide that will help you pick the right car battery charger, you are in the right place. With the increasing demand for efficient car battery chargers, manufacturers are now bringing more and more products on the market.
The market is now swarming with battery chargers that are showing promising specs and remarkable performance figures. However, I would suggest you settle for nothing but the best product.
To find that, here are some of the key takeaways you should take into account when buying the best auto car battery charger. Before I get to that, you should learn the difference between a jump starter and a full-on car battery charger. After that, let’s get the technical details out of the way first.
Since most cars operate on a 12V electrical system, you could easily get away with a 12V car battery charger. The voltage of the battery will be the same for most cars, but if you have other vehicles like a lawnmower, utility cart, or something similar, you can find 6V car chargers.
Additionally, you can also buy multi-functional chargers that can charge both 6V and 12V batteries. However, the more feature you want, the expensive it will get. While voltage remains the same, the difference in Amperage is something to consider.
A battery charger is designed to handle a certain amount of current flow. It can be high or low, depending on the type of battery charger you get. This is determined by the amperage rating. If your charger has a higher amperage, it will be able to charge a car a battery faster.
However, for a car battery, charging it faster isn’t a good practice. That’s why you should buy a charger that can detect the current condition of your battery and optimize the current flow to match the battery’s condition.
Instead of you doing all the guesswork, let the smart device figure it out for you. If the battery is full, the charger will switch to trickle mode, and if the battery is almost empty, it will increase the current flow until the battery is completely charged.
You need to make sure that the charger you are buying is easy to use and doesn’t require a lot of pre-technical knowledge. They should be as simple as pressing a button, adjusting the correct voltage, and connecting the wires. Some chargers have additional features like auto-shut-off mode or adaptive amperage adjuster.
There are some that also comes with a flashlight. You can also use these devices to charge your laptop, mobile, or any other electrical appliances. Make sure the charger you are buying has more than one USB slot. It’s always to welcoming sight.
Battery chargers that are portable are a must-have device for every car owner. You never know when your battery will run out of power, and having a handy tool like a portable auto battery charger can be a lifesaver when you are out on the road, stranded with a dead battery.
They are small enough to fit into your glove compartment and lightweight enough to be carried around all the time.
Having a battery charge level indicator is a must, especially if you are someone who is not familiar with charging car batteries. If you want to keep tabs on the charge level of your battery or want to know when the battery is fully charged, get a good charger that has indicators.
It can also serve as an alarm if you place the clamps in the wrong order or in cases of reverse polarity. This is a helpful feature for both the novice and an experienced driver.
You need to check your battery type first before choosing a battery charger. Most of us have a deep-cycle battery, while some cars use a standard lead-acid battery. Make sure the charger you are buying is compatible with your battery type.
Manual Vs. Automatic
Don’t buy a car charger that doesn’t have any automatic features. You don’t want to spend all your time keeping frequent tabs on your battery’s charge level. Let the charger do all the hard work.
When the battery is fully charged, the charger will switch to maintenance mode to prevent overcharging the battery.
Frequently Asked Questions
Q: What safety features do I need to look for in a car battery charger?
Ans: There are a couple of safety features that you should definitely look for. To begin with, you want an automatic charger. To prevent overcharging and overheating the battery, having an auto voltage and amperage detection feature is a must.
Most of the chargers have reverse polarity features as well as spark resistant clamps. Spark is the last thing you need when dealing with a car battery.
Q: Can I leave the charger on for too long?
Ans: If you have a manual charger, don’t keep it connected for too long as it can overheat the battery and potentially overcharge it. On the other hand, you can leave an automatic charger connected as long as you want.
