Cars are not only about maintenance but also it's important to have a keen eye on their batteries. Purchasing car batteries can also be quite tricky and most drivers or owners are intended with several brands and types. The car batteries in a vehicle should not be judged on their size. Though small, it plays many major roles in running the vehicle smoothly. Functions like starting your car, providing power to the infotainment system, and headlights give you an idea. The running engine charges the battery in the car. Over the year after numerous cycles, the battery will eventually die and needs to be replaced. 

This article provides you with the best batteries available on the market. Let's drive!!

Starting, Lighting, and Ignition Batteries (SLI)

• Most of the vehicles on the road come with starting, lighting, and ignition batteries or short SLI batteries.
• Like the name suggests, apart from starting the car, it powers all the electronics like the interior and exterior lights, infotainment system, etc.
• An SLI battery has a very short charge cycle. That is the time for the battery to charge and then discharge is fairly less.
• This type of battery can deliver power in short bursts of time like the starter motor to start the car.
• The SLI batteries are made up of 6 galvanic cells oriented in a series format which forms a system and provides 12 volts.
• Each cell provides 2.1 volts to give a total output of about 12.6 volts at full charge.

Lithium-Ion (Li-ion) Batteries

• This is one of the most underrated batteries of the lot as it is mostly used in PHEVs and is a little more expensive than the conventional Lead-Acid battery.
• A Lithium-ion Battery has become famous in the last few years. The recent hybrid vehicles and electric cars use a Li-ion battery.
• As compared to the other batteries the Li-ion battery significantly stores more charges.
• Another plus positive is that these batteries weigh less than conventional car batteries of the same power.
• Regardless of the use, the life span of the Li-ion batteries is long which is about 5-10 years.

Lead-Acid Batteries

• These are the batteries with the lowest maintenance.
• Unlike the other batteries Lead-Acid batteries are sealed hence they cannot be serviced. These batteries can only be replaced.
• Lead-Acid Batteries also work in short bursts to provide power to the starter motor.

Before you buy a battery

• The voltage in a fully charged battery is around 12.6Volts and it refers to the amount of energy stored in the battery.
• On the other hand, the current is the rate at which charge flows and is measured in amps.
• The most common type of battery used in Indian cars is the Lead-acid battery. The batteries consist of several plates immersed in an electrolyte solution.
• The electrolyte is a solution that constitutes 65% water and 35% sulphuric acid.
• It is the chemical reaction between the plates and the electrolyte solution that produces a current of 12.6 volts.
• CCA is also a thing to consider before buying or replacing a battery.
• The Cold Cranking Amps rating or CCA is the measure of how many amps the battery can produce for 30 seconds at -17ºC.
• Most of the car’s batteries have a rating of 350, 450, and 600 CCA. The more the rating easy it is to start the vehicle.
• CA or the cranking amps which is the measure of how much amps the battery produces but at 0ºC for 30 seconds.

Conclusion

Always check the voltage reading before buying a battery with the help of a multimeter. Read the right battery size mentioned in the car user manual. Kuwy is ready to assist you with further doubts.
