What to Consider Before Buying a Battery Charger for Car?

Before diving into the world of car battery chargers, there are a few essentials you might want to know. These will determine if the product is a perfect choice or not. Don’t make the mistake of purchasing a product that you’ll soon regret and complain about.

Usage

There are quite a few need-to-know basics when it comes to usage. Firstly, you’ll need to consider the weather. Some car battery chargers do not operate well under extreme weather conditions. More specifically, having too low or too high weather temperature.

Second, you might want to know the capability of the charger. Some are able to maintain and recharge batteries from large vehicles, but some can only handle smaller ones.

Lastly, the functionality and simplicity of the charger. Some require manual configuration while some are automated. Both have their pros, but so is with their disadvantages. Automated ones are as simple as plug and be done with it. Manual, however, you will need to regularly monitor the process.

Amps

Depending on how you want your car battery to be charged, you should look into the charger’s amperage capability. Viking and Schumacher usually provide different amperage options. Lower amperages than 4 amps are often used to charge batteries at a slow and safe rate, also known as trickle charging. This is usually done overnight. Higher amperage such as 50-amps can generally start a car within hours. That is more than half the speed of trickle charging.

AGM

For those who are not familiar with AGM, this is actually the type of battery you may have, also known as Absorbed Glass Mat. The reason why you should take note of this feature in car battery chargers is that different types of batteries tend to require different styles of charging. So, if you do have an AGM battery, make sure the one you’re purchasing one that is capable.

6V or 12V

Even home battery chargers need to be compatible with the voltage capacity of your batteries. Car batteries usually only need 12 volts. If you require other use for your charger, you may want to look for one that offers both 6V and 12V capability.

Maintenance

If you want to prolong the life of your accumulator, you will need to look for a charger that offers battery maintenance. Nowadays, most car battery chargers have these kinds of features. You just need to make sure you’re getting one since there are still those that are designed only for charging.

Is It Possible to Charge a Dead Car Battery?

Though it is possible, it mainly relies on the estimated life of the accumulator. Most car batteries can last long up to 6 years but can also be downed to 4 years from complications. If you think the accumulator has more life to it, it can definitely be charged back to life. There are usually instructions that come with the charger when jump starting dead batteries.

If for a reason the battery still won’t start, there are other factors to consider. It could mean faulty alternator, failed fuses, corrosion, flawed starter connection, or even as simple as the ignition switch.

Car Battery Chargers vs. Jump Starters

Often confused with the same use, car accumulator chargers and jump starters are actually two different devices with different purposes. Car battery chargers are those that are capable of recharging discharged batteries. They are only able to do their job while plugged into an outlet. That can be either a generator or household electric outlet.

Jump starters, on the other hand, are also known as emergency boosters or boost starters. They are not capable of recharging your accumulator but are able to help start your vehicle by acting as a substitute battery. That is only for a quick moment. Since they require a “charge” to jumpstart your car battery, they usually are recharged after each use. These chargers usually come with the jump starter.

Conclusion

With what we reviewed so far, there are too many factors and features involving car battery chargers. It can actually be frustrating to figure out the best one. But by just reading reviews, you should learn a lot about a product. Depending on your personal preferences, make sure you’re getting the best one for you. Remember, the highest rated car batteries may be optimal for others but not for your own good.
