How To Buy The Best Car Battery?

If you are buying a car battery to replace the original one, the following is the list of factors you should consider.


Generally, there are five types of car batteries highly available in the market.

  • Calcium-Calcium Batteries: These car batteries have calcium alloy plates for different charging. The low-cost batteries offer reduced fluid loss for a slower discharge rate. Overcharging may damage them.
  • Flooded Or Wet Batteries: This kind of batteries does not require any maintenance and is often spill-proof. The pocket-friendly units have insulated and freely suspended plates. The internal fluid of the batteries lasts until they are useable.
  • Deep-Cycling Batteries: These batteries are very much durable and mainly used for small boats, golf carts, and electric vehicles. The thick plates of these batteries offer increased charging capacity. The high discharge rate makes them imperfect for road vehicles.
  • VRLA Batteries: The batteries come along with regulated Sealed Lead Acid safety valves. These units are able to produce water to prevent fluid loss. They have GEL and AGM, two different designs. GEL technology has silicone to keep the acid in the form of a gel. The Absorbed Glass Matts are very much thin and lower internal resistance.
  • Lithium-Ion Batteries: These batteries are very much expensive. Very high-performance and limited editions of vehicles use them. The units are suitable for electric automobiles for higher fuel-efficiency to low eight.

Warranty Of The Battery

Normally, most of the car battery manufactures come up with warranties for their products. People generally go for the extended period of warranties for their batteries. In that case, you should go to the 24/84 warranty period. This code offers 24 months of free replacements and 84 months of partial payments.

Perfect Size And Fitting

Choosing and installing a perfect car battery play a major role in the lifespan of your car. To avoid any accident or mechanical vibration, you have to be careful if the product fits within the tray inside the car’s hood properly. You need to pay attention to the dimensions of the batteries and car’s tray, as well. It is better to consult a repairman for ideal installation and safety.

Requirements Of Power

It is very much important to look over the power needs and requirements of your owned car battery. You need to look carefully the Cranking Amps (CA) or Cold Cranking Amps (CCA) to test the battery’s tendency to power-up the engine in hot and cold temperatures. Generally, the increased CCA offers more power to your battery, unlike the other units.

Care And Maintenance

The batteries are usually categorized in low-maintenance units and maintenance-free units. The low-maintenance batteries come with unsealed caps for occasional watering. The maintenance-free units have sealed caps to let the electrolyte flow through them all by itself.

Condition Of Batteries

Always avoid a car battery which unit has been manufactured six before your purchase. You should look for a fresh battery, otherwise, the batteries lose their power in the warehouse. Each battery comes with their manufacturing codes, where the manufactures use alphabets for months and number as years. If you do not find any code on the unit, then you can check the mandatory shipping code.

How To Make The Selection Of Car Batteries Easy?

To keep the car running in decent condition, the car battery is regarded as an integral part of a car system. Its design is specially done to power the car wheels, and therefore, the poor quality car battery will not work at the best. In order to select the appropriate battery for your car, you have to understand the fundamental nomenclature for batteries. Some of the basic parameters you need to know are Ampere-Hour (Ah) rating, Cold Cranking amps (CCA), Cranking amps (CA), and Reserve Capacity (RC). It is known that the voltage for which the cars’ electrical systems are designed is standardized to 12V. The same might differ for other motorcycles. After you have acquainted yourself with these terminologies, you can proceed with the below section to make the car batteries selection easy:


Make sure you check the battery dimensions properly. Majority of the battery mounts or battery boxes are standardized; however, it is recommended to first check whether the dimensions fit your car perfectly or not. Those who are highly focused on properly maintain their car, for the car battery with loops or handles, will be more convenient.

Check The Ratings

Every vehicle comes with the owner’s manual that consists of the information related to all the standard parts required by car for consistent maintenance. You will be able to find the battery dimensions as well as the ampere-hour ratings, the CCA, CA ratings there. In case you don’t have the owners’ manual, check the top part of the body of the existing battery to know all the required ratings.

Do Not Go for Ah Rating

Make sure you never choose a car battery that has Ah rating lower than your prevailing battery. This is because it will let you suffer from some troubles initially, particularly the cold starts and similar others. Moreover, the battery life will be severely influenced. A car battery with a higher Ah rating will function well; however, if you choose a much higher rating battery, the same will cause slow charging issues and load on the alternator. If you reside in climatic conditions where the temperature is comparatively low, you need to choose a car battery with a higher CCA.

Reserve Capacity

A car battery with good reserve capacity will prove useful in situation the car’s alternator fails. Using the battery will keep the car and the included lamps running for a longer span.

Life of The Battery

The typically available car batteries are the dry cell batteries and lead-acid batteries. The dry cells are a tad more expensive, but they come to have a longer life compared to the lead-acid batteries. The car batteries depreciate the strength as time passes even when they are stored. To perceive the optimum performance, buy the one that is less than 6 months old. The majority of these batteries come with a shipping code on the case whereas some use a letter for the month and a number for the year; some make use of a numeric date.

Capability To Meet Your Car Needs

Make sure you receive the appropriate size as well as terminal locations for your vehicle. You have to check your owner’s manual, or you can look at an in-store fit guide prior to shopping. In some situations, the owners can substitute an AGM battery with a conventional flooded one to enhance longevity in warm climates. However, it is recommended first to consult a mechanic. There are many cars equipped with AGMs to sustain an escalating array of electrical components. Furthermore, the charging system might be configured specially for an AGM battery.

Compare Warranties

It is vital to select a car battery with the longest free-replacement period you can possibly. A car battery’s warranty is measured in two figures i.e., the free-replacement period and the prorated period. For example, a code of 24/72 denotes a free-replacement period of 24 months as well as a prorated warranty of 72 months. Once you are in the prorated period, the amount you would be reimbursed typically drops off rapidly. Be conscious that signs like low water levels and inappropriate installation could void a warranty.


All the above-listed best car batteries will definitely provide you the best value for your money. First of all, you have to match the battery with the car’s battery specifications for compatibility. It is important for a battery to fit perfectly and meet all the power needs and requirements accurately. We have provided a complete buying guide that you have to keep in mind while buying a replacement battery for your car.
