Batteries are one of the most important equipment of a car, particularly when it comes to starting the car. In the earlier days, when the electrical systems were limited, the engine was started with a crank, while a bell was used instead of an electric horn and the headlights were gas-powered. But with the advancement of technology, car batteries became widely popular as the cars became equipped with electric starters. The Hudson Motor Car Company was the first company to feature a standardised battery in 1918 and the sealed batteries which did not require refilling was invented back in 1971.
So what does an automotive battery actually do? An automotive battery a is a rechargeable battery which supplies electric energy to a car. The main motto of an automotive battery is to start the engine and traditionally these kinds of batteries are called SLI-starting, lighting and ignition. Apart from starting the engine, an SLI battery provides the extra power necessary when the vehicle's electrical requirements exceed the supply from the charging system. Moreover, it also works as a stabiliser and evens out potentially damaging voltage spikes.
We all, who own a car, are very much acquainted with the fear of being stranded in the middle of nowhere with a dead battery. So it is very important to choose the right battery for your car. In this one stop article on the best car batteries, we have discussed anything and everything you should check before you set your mind on to but the best battery for your vehicle.
We have shed lights on what are the different types of car batteries available in today's world? In what sizes they come up? What are the different attributes you should check before you buy the battery for your car? And most importantly we have made a list of the best car batteries available in the today's market. So, go through the whole article and get an in-depth insight about the car batteries so that when you will buy the next battery for your car, it would provide supreme longevity and would last for several years.
~Types of Car Batteries~
Generally, the modern day car batteries come in two basic variants; one is the more traditional lead-acid batteries and the other is the more advanced absorbed glass mat or AGM batteries. We have explained the both types of car batteries below:
Lead-Acid Batteries: The lead-acid battery was invented in 1859 by French physicist Gaston Planté and is the oldest type of rechargeable battery. The traditional lead-acid batteries once demanded regular maintenance and required drivers to periodically top off the water in the electrolyte solution, the liquid inside which is the premium power source of this kind of batteries.
- The modern day lead-acid batteries come maintenance free and consume far less water than traditional “flooded cell” ones.
- The basic difference between the new tech low-maintenance lead-acid batteries and the conventional lead-acid batteries is that the former one retains their fluid for the life of the battery, and the caps on these models aren’t meant to be removed.
- Normally the lead-acid batteries cost much less than the AGM batteries and won't hold a charge for as long as the AGM batteries do.
- Moreover, the lead-acid batteries are less able to tolerate a deep discharge, unlike the AGM batteries.
AGM Batteries: For the cutting edge techniques like fuel-saving stop-start systems, electronic safety and convenience features and power outlets for mobile electronics; the AGM batteries are becoming standard equipment in most of the modern day cars.
- The main difference between the AGM batteries and the conventional flooded lead acid batteries is that the electrolyte present in the AGM batteries is held in the glass mats, unlike freely flooding the plates. In the AGM batteries, very slender glass fibres are woven into a mat to increase the surface area enough to hold sufficient electrolyte on the cells for their lifetime.
- Moreover, the fibres which compose the fine glass mat do not absorb nor are they affected by the acidic electrolyte.The plates present in an AGM battery come in many shapes- some are flat, others are bent or rolled.
The AGM batteries are designed to better stand up to repeated draining and recharging cycles than the conventional lead-acid batteries. So if you don't use your vehicle for a long period of time, it won't put you in as much trouble as a traditional lead-acid battery would do. Moreover, these kinds of batteries can better tolerate a deep discharge and is more likely to recover fully if it is accidentally drained. The AGM batteries cost you 40 to 100 percent more than the conventional lead-acid batteries.
~Size of the Car Batteries~
The modern day car batteries come in a variety of sizes and it is very important to select the right-sized battery for your vehicle so that it fits perfectly and provides optimum power. If the terminals of the batteries are placed wrong, it is most likely that your car's cable might not reach, or they may not fit perfectly. So before you buy the next battery for your car, check out the below-given fit guide and read your owner's manual. Generally, most of the retailers install the battery for free of cost.
Size 65 (Top Terminal): These kinds of batteries mostly fits large cars, trucks and sport-utility vehicles from Mercury or Ford.
Size 75 (Side Terminal): Ideal for some General Motors mid-sized and compact cars.
Size 24/24F (Top Terminal): Fits most of the Honda, Nissan, Toyota, Acura, Infiniti and Lexus vehicles.
Size 34/78 (Dual Terminal): Suitable for large Chrysler vehicles and many 1996-2000 GM pickups, SUVs, as well as mid-sized and large sedans.
Size 35 (Top Terminal): Perfect for the recent Honda vehicles, and most Nissan and Toyota vehicles.
Size 51R (Top Terminal): Ideal for many Japanese vehicles including Honda, Nissan and Mazda.
Size 47 (H5) (Top Terminal): Suitable for Chevy, Fiat and Volkswagen vehicles.
Size 48 (H6) (Top Terminal): Fits most of the European and American cars from BMW, Audi, Mercedes, Cadillac, Volkswagen, Chevy, GMC, Jeep, Mini and Volvo.
Size 49 (H8) (Top Terminal): Ideal for the European and Asian cars including BMW, Audi, Mercedes and Hyundai models.
Car Batteries Buying Guide: Points You Should Keep in Mind
1. Check that the Size of the Battery Fits your Car
Before you buy a car battery, check whether the size of the battery and the terminal locations (or type) fits with your car. Read the owner's manual of the vehicle and the in-store fitment guide or our battery size list. It is the most crucial thing you should keep in your mind. Also, check the cold-cranking amps and reserve capacity test of the battery.
2. Choose the Product which did Well in the Battery-Life Test
Checking the battery-life test is very important, especially if you live in a warmer climate. The high temperatures are very harmful to the batteries as it increases the vaporising of the electrolyte as well as plate corrosion. It is must for those who love to go for long drives.
3. Ensure that it is a Fresh Battery
Batteries decay strength over time, even it's in the storage. So to get the optimum performance, make sure that the one you are going to buy is not more than six months old.You will get the shipping code on the case.
4. Compare Warranties
Always go for that battery which is giving you the longest replacement period for free. Generally, a battery's warranty comes in two halves- a free replacement period and the prorated period; when you will only get partial reimbursement. Remember that signs of neglect like improper installation or low-water levels can void the warranty.
5. Maintain the Battery Properly
Be attentive to your car's battery and maintain it properly. Check if the time for replacement is approaching or not and if your car needs a change in the battery, do proper research work and make a convenient schedule.
6. Check Batteries Annually
Although most of the modern day cars don't require any maintenance, we would suggest you to check the load test of your vehicle by a mechanic, annually once, after your car gets old for two years and if you live in warmer climate or after your car gets old for four years and if you live in colder climate.
