Review For Top 10 Rated Automotive Battery Chargers Buying Guide For 2019

A dead car battery can be caused by several reasons, one of them being their tendency to mysteriously die at the most inconvenient times. Therefore, it is best to be prepared with a car battery charger at all times to avoid being stranded in the middle of the road.

Using a battery charger to charge your car battery is relatively inexpensive and quite convenient as compared to other alternative methods. A battery is considered to be dead or flat when it has lost its charge. A charger simply replaces that charge through positive and negative leads.

As car batteries are incapable of sustaining themselves, they need to be recharged repeatedly. It is best to purchase a battery charger to go with your battery-powered car. If you have sufficient mechanical knowledge, this won’t be a difficult task for you.

However, most people are clueless about the effect of battery chargers on a car’s battery. Let me help you in choosing the most suitable emergency equipment for your car. Here are my picks for the 10 best car battery chargers that can instantly and efficiently help you get out of stressful situations.

Helpful Tips to Choose the Best Car Battery Charger

There are various battery chargers available in the market. Ranging from one that charges approximately 2 amps per hour and needs a complete day to fully charge a flat, 48amp battery up to the one that charges around 10 amps an hour.

The higher the charge output, the faster your car battery’s charging; however, fast charging can cause the battery plates to deform.

Discover Which Battery Charger Is the Best for Your Usage

You should be aware of the fact that not all battery chargers can be used in all kinds of cars. Here are some important factors to consider before purchasing a car battery charger:

Type of Battery

Your car battery type plays an essential role while buying a battery charger. Some batteries can tolerate over-charging to a great extent and they can be recharged through a continuous voltage or current source.

Some absolutely cannot withstand over-charging and need their charges to have temperature or voltage sensing circuits and a microprocessor controller so that the charging voltage and current can be adjusted accordingly.

In addition to the overcharging-tolerance level, most car batteries are lead-acid batteries and can handle any type of battery charger. But other special battery types like AGM, Deep Cycle, and Gel Cel have particular requirements and not all chargers are manufactured to fulfill them.

Battery Voltage and Size

The battery doesn’t always indicate the physical size of the battery but it does indicate the amount of amp time (in hours) your battery stores. You can use a small charger with fewer amps to charge your battery.

However, the greater your battery stores, the more time it will take to fully charge. Therefore for a quick recharge, you may choose a car battery charger with more amps.

An ordinary cost-effective car battery charger can usually accommodate 12V batteries and sometimes handle 6V batteries as well. You can also opt for a charger that can handle both volt applications.

Desired Results

While choosing a car battery charger, it is vital that you keep your desired outcomes in mind. If you want to keep the battery of your classic and precious car charged throughout the year, then you can use a low current charger that will charge your battery gradually.

If you desire to restore the power of your car battery quickly, then you can opt for a powerful, fast battery charger.

Types of Car Battery Chargers

Knowing about different types of car battery chargers will help you determine which one is the most suitable for your vehicle.

Type 1: Simple Charger

A simple charger supplies a constant or pulsed DC power source to the battery it is being used to charge. It doesn’t change its production based on charging time or the battery charge.

It is relatively inexpensive and takes more time to fully charge a car battery as it is set to a lower and secure charging rate. They are capable of supplying either a constant current or a constant voltage to the car battery.

Type 2: Fast Charger

Fast chargers can charge car batteries without causing any kind of damage to the internal cells. They use the control circuitry in the battery to charge them with a rapid rate.

The control circuitry needs to be developed internally in the battery, in the external charging unit, or in both. Such battery chargers come with a built-in cooling fan that helps in controlling the temperature of the cells and in keeping them at a safe level.

Type 3: Solar Charger

Portable solar chargers convert light energy into low voltage DC current and are used to charge batteries of cars, boats, RVs etc. Although they acquire the needed energy from the sun only, some of them can also be used in low light.

Type 4: Trickle Charger

A trickle charger is ordinarily used to charge batteries with small capacity or maintain batteries with a larger capacity. It is a low-current battery charger and runs on a trickle-charging operating mode.

These chargers can be left connected to the battery for an infinite amount of time, although this greatly depends on the type of battery and the technology of the trickle charger being used.

Car batteries consume the extra power generated by the engine and most of them have an extended lifespan. They last for about 5 years or more without any need for replacement or recharging. But even the ones that are of the highest quality run out of power with time.

Once you’ve successfully purchased your car battery charger, remember that using it is a simple and easy task.

How to Charge a Car Battery with a Battery Charger

Learn how to charge a car battery with a battery charger in a few simple steps.

Step 1. Check the electrolyte level of your battery and see that it is just covering the battery plates. If you see that it isn’t at a sufficient level, then top up the battery and remove any dirt and debris from the battery posts.
Step 2. If there’s a socket near your car, you don’t need to remove your battery from the tray.
Step 3. Make sure that the charge rate stays constant i.e. around 3 to 4 amps.
Step 4. If your car consists of an alternator, disconnect the terminals before starting the charging process to avoid causing any damage to the alternator.
Step 5. If the cell caps are connected, detach them to allow ventilation.
Step 6. In case of low charging rate, leave the trough covered.
Step 7. Distinguish the positive lead from the negative lead. The positive one is usually red in color and needs to be attached to the positive battery post. The negative lead, usually black, is to be clamped to the negative terminal.
Step 8. Plug your newly purchased battery charger into the socket and turn its power on.
Step 9. If the indicator light turns on, it indicates that the charging has started.
Step 10. You can use a hydrometer to keep a check on the charging level.
Step 11. Once the battery is fully charged, the cells will bubble and release gas.

If you are interested in knowing more about this topic, then learn how to charge a car battery.

Unplug the Charger before Disconnecting it from the Battery

Once your car battery is fully charged, make sure you turn off the power and unplug your battery charger. As mentioned in the last step, the cells bubble and give off gas at the end of the charging and removing the terminal clips without turning the power off may cause sparks and ignite the gas.
