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.

  1. Battery Type

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.

  • Battery Power

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.

  • Battery Chemistry

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.

  1. Power Need

Know the specific power requirement – like the voltage, amperage, clamp amps, etc. – of your car battery for choosing a compatible car charger.

  • Voltage

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.

  • Amperage

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.

  • Clamp 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.

  1. Safety Options

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.

What is Reverse Polarity?
Reversed polarity is created when the polarity of any power outlet gets reversed. There are two types of wires: neutral and hot. If by mistake, one wire is connected to the place of another wire, the reverse polarity occurs. It can create dangerous sparking, which may lead to gas ignition around the car-battery. It can even run the risk of explosion.

  • Maintenance/Float Mode

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.

  • Tickle Charge

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.

  • Battery Diagnostics

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

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.

  1. Technical Features

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.
