Tips for Charging your Battery
It is not enough that you have the best charger with you. For the best outcomes, below are some of the most important things that you have to keep in mind:
Make sure that you connect the positive post with the positive terminal. The same thing is true in the case of the negatives. Luckily, many of the modern chargers have protection from reverse polarity.
Before charging, you need to have a quick inspection of the terminals and make sure that they are clean. If it is already covered with white powder, do not touch it as it can cause skin burn. You can clean it with sandpaper and a cleaning solution that will get rid of the dried sulfuric acid.
See to it that you are using a battery charger that is suitable for the type of battery that you will charge. There are different types of batteries and there are some chargers that are designed specifically to work only with a specific type.
Determine the voltage of the battery that you are charging. Refer to the manual from the manufacturer of your vehicle. This will let you know the specific charging requirements of the battery that you have.
Read and understand the directions from the manufacturer. Make sure that you religiously follow the steps that are specified, especially those that concern safety.
Once you are done, check the battery to be sure that it is charged. A hydrometer can be useful. You can also simply just turn on the engine and look at the battery gauge.
Essential Factors to Consider
To make it easier for you to decide which one to purchase, below are some of the most important things that you need to take into consideration:
Reviews: The first thing that you have to do is to consult with what other people have to say. You can ask around from people you know or go online and read reviews. The real-life experiences of other buyers can provide you with valuable insights, making it easier for you to narrow down the possibilities.
Ease of Use: The charger will be useless if it is complicated to use. That being said, you should look for one that is as user-friendly as possible. The manufacturer must provide comprehensive instructions on how to make the most out of their product.
Durability: See to it that the charger is made from premium materials that will not be easily prone to wear and tear. They must be able to resist external elements, such as water and dirt to be able to deliver long-term functionality.
Safety: Evaluate the safety features that are present in the product. For instance, it should not create sparks and there should be protection from overcharging and overheating. The charger must also be certified and must have undergone a rigid test to prove that it is indeed safe.
Compatibility: Start by knowing the type of battery that your car has. Then, find a battery charger that will be suitable for it. As noted above, not all types of chargers will work with all kinds of batteries.
Versatility: By choosing a product that is versatile, you will enjoy your money’s worth because the product can be useful in more ways than one. Choose a charger that works for all types of batteries. More so, it will also be good if it can double as a flashlight so that it can be useful in emergency situations.
Charging Ports: Most models will have a single charging port. In the case of the more advanced options, on the other hand, there are multiple ports, which will allow you to charge simultaneously.
Speed: You also have to research about how long does it take before the battery can be charged. This will depend on the size of the battery, but the capacity or performance of the charger will also have an influence on such. A charger with more amps will be able to revive a dead battery quicker.
Display: Although not necessary, it will also be a good thing if the charger comes with a display, which will make it easy to monitor the status of charging, and hence, eliminate guesswork. No more need to turn your engine first to check if the battery has already been fully-charged. The display on the charger will already show the status.
Battery Size: The size of the battery is an important consideration because it will determine the power that is necessary for the charger to have. If the battery is too large while the capacity of the charger is too low, you cannot expect optimal charging outcomes.
Price: A lot of budget-conscious buyers will most probably look for the cheapest product that is available in the market. I strongly oppose this. At the end of the day, it is better to spend for an expensive product if this means that you will enjoy top-notch functionality. This can avoid frustration in more ways than one.
Warranty: Look for a battery charger that comes with an extensive warranty coverage, which will provide you with confidence in its quality. However, remember that the manufacturer will not honor the warranty if the product is used incorrectly or if the problem is a result of your negligence.
As it has been discussed in this short buying guide, the best car battery charger is one item that you must always have in your vehicle. You’ll never know when it can be useful. When you are confronted with an unfortunate situation in the middle of a road where help is scarce, with your charger, you will not be inconvenienced.
