How To Choose The Best Car Battery Charger

Buying a car battery charger is not as easy as it may sound. Multiple factors are going to impact your choice. To begin with, you need to understand if you just need a normal battery charger, or are you looking for something that can also maintain the battery of the car. There are also some differences between the battery chargers and jump starters. Let us help you in buying the car battery charger by sharing a short buying guide about this. Here are the points that you must consider while purchasing a car battery charger.

→ 1. Type of Battery Charger

You can start by looking at the type of battery charger you want. This includes a choice between the automatic and manual car battery charger. The automatic ones are a lot better as they can easily prevent overcharging of the battery.You can also check the kind of charging mechanism the car battery charger has. There can be a difference in the power source as well. Some of the car battery chargers may come with an internal battery that can double up as a jump starter. Also, ensure that the car battery charger is compatible with the type of battery that is installed in your car. This may differ from a standard battery to a deep cycle battery.

→ 2. Specifications

You must also look at the specifications of the car battery charger. Check for the voltage and the amperage of the car battery charger. This will define the power rating. There are some of the car battery chargers that come with a variable amperage. You will be able to change the amperage between 6 Amps to 20 Amps. Higher the amperage, the quicker the charging will be. It should be noted that high specs would bump up the price of the car battery charger. There has to be a trade-off between the two things.

→ 3. Safety Standards

Safety is of top priority. A faulty car battery charger may cause a fire as well. In such a case, you would want to ensure that you are buying something safe to use. To begin with, check if the battery charger has a reverse polarity alarm. It should also be having an overcharge protection system. Apart from this, buy the ones that have a float mode and battery testers included in them. Lastly, ensure that the clamps of the battery charge have spark proof clamps.

→ 4. Portability

You may take your car battery charger with you on road trips. This can prove to be helpful in case of any emergency. In such a scenario, you want the car battery charger to occupy less space in your car. Ensure that it is portable and it comes with a carrying case. If it is only a charger, we assure you that it will be very portable, but if it is also a jump starter, it may occupy a certain space in the car. Just look at the dimensions to get a fair idea about the portability.

→ 5. Display

You do not want to overcharge your battery. The best possible way to ensure that you are not overcharging the battery is to buy a car battery charger that has a display or an indicator. A battery charge with the indicatory will raise an alarm in case of reverse polarity. This will also help you in ensuring that you do not end up damaging your car’s battery. Some models have a display on them. The display can help you in reading the charge levels of the battery.

→ 6. Extra Features

You can look for the more versatile models that have extra features while buying a car battery charger. For example, you can look for something that is not only a battery charger but that is also a jump starter. Some of them have a USB Phone Charger and an air compressor integrated into them so that you can inflate the tires as well. It is better to consider the car battery charger which comes with this added utility.

→ 7. Price

The price of the car battery charger will vary based on the capacity of the car battery charger. The higher amperage will attract a premium. In addition to this, the models that are loaded with an air compressor or a battery will be a little more expensive than the plain vanilla car battery charger.

8. Warranty

You must also look at the warranty policy applicable to a car battery charger. The norm is 12 months to 2 years but some models offer a longer warranty as well. The maximum that we came across was 10 years. You must only buy a car battery charger that comes with a warranty policy. This will help you in getting complete peace of mind while you are using the equipment.

Battery Charger Frequently Asked Questions

  1. Why does my car alternator cannot charge my car battery but an external car battery charger could?

A car alternator is designed to charge a battery with a low charge, but, it cannot charge a dead or fully drained battery. This is the sole reason for using an external car battery charger. An external car charger is designed in such a way that it could charge a dead or fully drained battery with ease.

  1. Should I charge my car battery at 2 amps or 10 amps?

We would recommend charging your car at 10 amps. One of the main reasons why we recommend using 10 amps charging is comparatively faster. In general, if you use a 2 amps charger it would take about 24-hours to fully charge a 48 amps dead battery. On the other hand, if you use 6 amps or 10 amps charger, it could charge your 48 amps car battery within comparatively less time.

  1. What reading should a fully charged lead-acid battery show?

When it comes to a lead-acid battery that was dead and charged using an external car battery charger if the battery is fully charged or close to full charge, then the reading should be near 13 volts or if it is close to fully charged, it should be between 11 and 13 volts.

  1. Are brand and warranty important when it comes to an external battery charger?

No, when it comes to car battery chargers, the brand is not important. If you check the market, you would find that majority of the external battery chargers are from brands that are not well-known to most people. Therefore, it is not the brands that you must consider, but the customer reviews. Now, about the warranty, you must not consider purchasing an external car battery charger without a warranty.

  1. Is it okay to leave an external car battery charger connected to the car battery overnight?

Yes, it is okay to do so, but only if the charger is 2 amps and not 6 amps or 12 amps. You must remember, in general, a 2 amps charger would take 24 hours to charge a 48 amps car battery. However, it takes 3 times less with a 6 amps charger and 5 times less with a 10 amps charger. Therefore, if you are using 6 amps or 10 amps battery, you shouldn’t leave the charger plugged in overnight.

  1. Trickle charging is better than other charging?

Yes, trickle charging is considered to be the best when compared to other types of charging. However, trickle charging is slow and it is best to prevent overcharging. Therefore, if you are a person who wants the car battery to be charged soon, then trickle charging would not be a wise choice for you.

  1. Is it important to disconnect the battery from the car system, while charging using an external car battery charger?

There are two cases, if you are using a trickle charger, you need not disconnect the car supply, but if you are using a full power regular charger, you must disconnect it from the car.
