How to Buy the Best Car Battery Charger
1. Type of car battery
Before making the purchase decision for a car battery, you need to consider the type of battery that you have in your vehicle. Most vehicles will use a lead-acid battery because this is the industry standard in default type of battery that manufacturers tend to ship their car with.
However, if you have a premium car brand then you may have a higher performing battery like an AGM battery inside your vehicle. You need to ensure that the car battery charger is compatible with this type of battery even if in general terms, the car battery charger is universally compatible with most car batteries.
Most cars have a 12 V battery under the hood. However, there are some vehicles that come equipped with different voltage batteries like 6 V, 18 V, or 24 V. Those are generally vehicles like motorcycles, SUVs, trucks or even RVs. You need to make sure that the car battery charger you want to buy is able to send her the necessary voltage to charge your battery.
3. Peak Amperes
The Amperage is basically the amount of current that the charger is able to send to the battery for the charging process to occur. Generally, the higher the Amperage that the charger is able to say, then the faster it will be able to charge your car battery. This is normally referred to Amp per Hour or AH.
So as to have an efficient charging process, it is recommended that you go with a car battery charger that has a sensing mode that will automatically detect the right amount of amperage to send to your car battery for optimal charging occur.
This is advantages in the sense that it helps boost the efficiency of the charging and does not cause damage to the internal circuitry of your battery by sending an excessive amount of current in one go.
Since the car battery charger deals with electricity that can be hazardous to your health, it is important that it is equipped with technologies that make it safe to use. Especially if it is handled by absolute beginners who have never used a car battery charger before.
Here are some features to keep an eye out for when try to find a good car battery charger online:
- Auto current: The auto current is a feature that will detect the right amount of voltage and Amperage to send to your car battery. In doing so, it does not cause your car battery to overheat and charges your battery in a safer and more efficient manner.
- Reverse polarity: Connecting the wrong terminals of your car battery during charging is a common mistake. Your car battery charger must be able to detect when you connect it to the wrong terminals and automatically shut down the charging process.
- Fire resistant: Sometimes when connecting your car battery charger to the terminal of the battery it creates sparks. Those sparks can potentially cause a fire. Therefore, it is a good idea to choose chargers that do not create sparks.
5. Average Charge Time
The average charge time of the car battery charger will depend on the amperage that it is able to send as well as the capacity of the battery you are trying to charge. The higher the capacity of the battery, the longer it will take.
If you have a high-capacity car battery, it is recommended to go with a heavy-duty car battery charger that is able to send a high amperage current.
If you’re planning to carry your car battery charger with you, then it is important that it is lightweight and compact so that it can be portable. Additionally, it is always a good idea to go with a model that comes with a handle which makes it significantly easier to carry the car battery charger around.
7. Ease of use
You do not want a car battery charger that is excessively difficult to use.
In most cases, this is easy to use a device that even absolute beginners can operate. All you have to do is connect the terminals to your car battery studs and then switch on the car battery charger for the charging to begin.
Once charging has been done, it is important that the charger also has a light system that alerts you. In addition, it is also beneficial to have a model that can display a percentage of the charging process so that you may know at all times how much charge your car battery has.
As we have seen, the car battery charger is able to recharge your battery, whether it is a 12 V battery or any other voltage battery in a quick and easy manner. You do not need any experience to use this device at all.
Moreover, there are multiple technologies operating inside the car battery charger that makes it safe to operate. Don’t worry, you do not run the risk of it exploding in your hand while recharging.
