How to Choose the Best Car Battery Charger?
Every car battery needs to be recharged after a certain period. When your car battery is fully charged, you can hope for reaching the destination timely without any unwanted hazard on the road.
However, many companies are producing car charger nowadays with various specifications under diverse price ranges. Let’s see some essential factors you need to consider before choosing the best car battery charger for your adorable car.
The charger is supposed to work with your vehicle’s battery. So, the type, size and chemical reaction of the battery determine what kind of charger it needs to work with.
Vehicle Battery Type
What is the type of your vehicle? If you wanna use the same charger for a classic car, small boat, garden tractor, or light truck, then find a charger compatible for multiple batteries.
Find a 6v automotive battery charger, when you have a classic car or tractor bearing 6-volt battery under the hood. Conversely, if you wanna charge the 12-volt battery of a small car, then a 12v battery charger would be enough.
However, some vehicles may come with 18-volt or 24-volt batteries. So, buy a car battery charger which is compatible with the vehicle battery you wanna charge up.
The car batteries vary depending on chemical formulation like lead-acid battery, deep cycle battery, AGM battery, Gel Cell battery, etc.
The lead-acid batteries are known as default type battery according to the industry standard. Usually, most of the car batteries belong to the lead-acid category.
However, it would be safer to know the chemical type of your car battery to find the best car charger.
Know the specific power requirement – like the voltage, amperage, clamp amps, etc. – of your car battery for choosing a compatible car charger.
Generally, the car battery chargers can draw electrical power from 110v or 220v AC power outlets of home or garage and convert this power to DC current before sending power to a 12v car battery.
An amperage is a measuring unit of the flow of electricity per second during the cycle. In general, the car chargers vary depending on their amperage versions, like 10-amp charger, 20-amp charger, etc.
Car chargers featuring higher amperage not only charge faster but also lasts longer. However, high amperage chargers would cost a bit more than their low amp counterparts.
Rate of Charge
Generally, a car charger features 2 amps to 6 amps of charging rate. The smart car chargers come with a built-in gauge or warning light for indicating the rate of charge in amps.
The charger clamps that are used to connect the wires feature an amperage rating. Generally, the car battery chargers come with clamps with the amp rating of 50 amps or higher. So, keep in mind that your charger clamp’s amp rating shouldn’t be lower.
Undoubtedly everybody tries to handle the battery charging process cautiously. However, an accident happens accidentally. So, there should be no compromise for the safety issue when you are looking for a charger for your car battery. A standard car charger featuring proper safety options can put off the risks that might damage your car battery.
Reverse Polarity Warning
You may connect the plugs incorrectly due to stress or hurry. However, a smart car charger can detect reverse polarity situations automatically and shut off the charging mechanism. Thus, it can prevent any sparking and avoid the further risk of explosion.
An automatic vehicle charger features flat or maintenance mode, which is smart enough to identify when the battery is fully charged. If so, the initial step of the battery charging process is blocked. When the charging status reaches 85% the charger system enters flat/maintenance mode.
Otherwise, the overcharging battery may lead towards overheating, internal damage, or even battery-explosion. The maintenance or flat mode safety option not only saves the battery from the risk of getting overcharged but also prevents it from the consequential damages.
The trickle charge is almost the same as the flat mode. The tickle charging option works for maintaining a hundred percentages of charge rates. This feature keeps the car battery fully charged constantly without compromising safety.
Spark Proof Charging Clamps
Certainly, you are cautious while connecting the charger’s clamps with your vehicle battery. Though handling with care, sparking may happen by chance.
The standard car battery chargers are blessed with fire-resistant spark proof clamps that prevent any risk of sparking during the connection.
Every battery wears out through the course of time. For instance, lead-acid kinds of batteries tend to create a layer of sulfate on their lead plates which may reduce their capability of getting fully-charged.
Some intelligent car chargers can diagnose this unsound battery condition. Their smart system would warn you that your car battery can’t accept a full charging session. And, the smarter ones can even correct this issue.
Battery Maintenance or Tending
You may not get your classic car out on the road regularly. If so, then it is wise to buy a charger that offers battery tending or maintenance feature.
However, this safety option is quite helpful for some other vehicles which are also used rarely, like a boat, motorbike, RV, garden tractor, etc.
Auto current feature refers to a sensing mode that makes a charger capable of detecting the right amount of amperage and voltage for delivering to the car battery. This safety option regulates the charging procedure safely and saves the car battery from getting overcharged or overheated.
A standard car battery charger comes with a bunch of intelligent features that not only makes the charging process safer and easier but also keeps car battery sound for long years.
Manual or Automatic
The smart car chargers can diagnose the current charge status of your car battery. The charging process would start automatically. The most interesting fact is that an automatic charger would stop the charging process automatically for preventing the battery from getting overcharged.
Average Charging Period
When you connect the car-charger with power outlet as well as car-battery, the charging process starts working. During the one-hour charging session, the amount of current delivered from charger to the battery is measured by the unit “Amperage per Hour” (AH). The higher the AH delivered by the charger to the battery, the faster the charging process.
Assume your car bears a 50AH battery. Now, if you pick a 10-amp charger, a full recharging session would take about 6 hours; whereas, the 20-amp charger would take about 3 hours to perform this task.
Rule of Thumb for Calculating Full Recharging Period stands as follows. Divide the battery amperage hour by the chargers amp rating. Then, add 10 percentages of extra time for all over the completion of the charging process.
(Battery AH / Charger Amp Rating)+10%= Charging Period
Micro Processor Mechanism
Today the standard 12v car battery chargers are equipped with microprocessors through the advancement of science. The microprocessor controlled mechanism has made the car charging process safer and efficient. This safety option not only improves the charging capability but also recovers or conditions the battery, when necessary.
The smart battery chargers are capable of running the charging procedure into multiple steps, like battery diagnosis, recovery, soft charging start, bulk charging, charge absorption, trickle charging, maintenance mode, etc.
However, the charging steps may vary depending on the charger’s manufacturing brands. Multiple step charging option not only makes the charging process safer and flexible but also assists the charger’s system in controlling each charging step more accurately.
Multiple Charging Modes & AMP Rates
Some high-performing car batteries bear high (Hi) and low (Lo) switch which facilitates the user to choose among multiple amp rates. Generally, car chargers offer two options. The options of charging rates may be 2 amps and 10 amps or 3 amp and 6 amps.
If you wanna charge your car battery within a short period, then choose the option offering a higher rate of charge. This multiple charging rate options would allow you to charge a small to a large battery.
Solar Charging Mechanism
Usually, chargers consume power from the wall power outlets found in the homes or garages. However, there are some solar chargers that can also get power from the sun rays. This is quite amazing. It would allow you to recharge your car-battery on the way when you are set off from home for a long trip.
It is wise to buy a lightweight and compact car battery charger, which you can carry while traveling on the road. It gives you the opportunity to go on long trips. You can easily keep a portable car charger inside your car’s glove box, or car-trunk, or even inside a carry bag.
Before buying any car battery charger, make sure that the device is easy-to-use. The standard car chargers are blessed with a LED light which would facilitate you to charge the battery in the dark.
Furthermore, the well-designed car battery chargers are capable of drawing power from your car’s cigarette lighter. Some car chargers come with USB slots which allow them to consume power from other devices like Smartphone, laptop, etc.
What if, your car battery charger offers some bonus feature like jump starting cables. It would be an additional benefit while you are stopped up on the road with a dead battery. Make sure the jumper cables are at least 12 feet long for ease of use.
