What are the types of car batteries?

Car batteries: are they all the same? You might be shocked to hear that there are numerous options if you’re not used to changing your own auto battery! The majority of batteries function essentially in the same way: by converting chemical energy into electrical current. The biggest variations in battery kinds and sizes, however, are in how they are made.

There are two fundamental types of car batteries: the more conventional maintenance-free and the more sophisticated absorbed glass mat (AGM). The followings are the common types of car batteries:

  • Lead-acid (regular)
  • Absorbed glass mat (AGM)

 

Lead-acid (regular)

Drivers once had to regularly top off batteries’ electrolyte solution, which is the liquid that provides the battery’s electricity. Compared to conventional “flooded cell” batteries, modern maintenance-free batteries use significantly less water.

Low-maintenance batteries don’t need to be filled with fluid, and their caps aren’t supposed to be taken off. Some batteries can still be filled with distilled water to top them off; with careful care, these may endure longer in hot regions.

In general, lead-acid batteries are more affordable than absorbed glass mat batteries. It is less able to withstand a deep discharge and won’t maintain a charge for as long.

Absorbed glass mat (AGM)

AGM batteries are designed to withstand repeated cycles of discharging and charging better than regular batteries. Modern technologies like fuel-saving stop-start systems, electronic safety, convenience features, and power outlets for portable electronics all increase the need for electricity, hence they are increasingly being included as standard equipment in more cars.

However, AGM batteries might cost 40–100% more than well-regarded conventional batteries. If you occasionally leave your car idle for extended periods of time and the battery discharges, you might want to get one. AGM batteries are more resilient to deep discharges and are more likely to recover completely if they are unintentionally discharged.

Other types

The battery types mentioned above are sufficient for the majority of people, but there are a few more that merit mentioning, including:

  • Deep cycle battery
  • Lithium-ion battery

 

Deep cycle battery

The best batteries for supplying consistent, low current power for lengthy periods of time are deep cycle batteries, commonly known as marine batteries. Their capacity to continually recover from cycles of severe discharge and recharge without suffering harm, as would ordinary batteries, is how they got their name. Deep cycle batteries are better suited for vehicles like RVs, boats, and golf carts that require power electronics without an engine running rather than cars, trucks, or SUVs.

Lithium-ion battery

For the majority of modern hybrid and electric car high voltage battery packs, lithium-ion batteries are the de facto norm. Compared to conventional batteries, lithium-ion batteries have greater energy storage capacity, charge more quickly, are lighter, and last longer. Some more recent cars have 12-volt lithium-ion batteries built in from the factory.

What are the things you look for in a car battery?

There is no one “best” car battery to purchase when looking for a new one. Which battery is ideal for your particular vehicle’s make and model, instead?

Depending on the frequency and length of the excursions as well as the weather, the typical automobile battery has a lifespan of only three to five years. Here are some pointers on things to watch out for when purchasing a new automobile battery.

  • Check for manual
  • Battery Freshness
  • Reserve Capacity
  • Power requirement
  • Maintenance
  • Warranty
  • Types and position of the terminals
  • Ampere hour (Ah)
  • Battery life
  • Previous experience

Check for the owner’s manual

You can save some money by purchasing your own car battery rather than having it installed by a manufacturer or mechanic. But if you purchase the incorrect battery for your car, it will be a complete waste of money.

You’ll need to consult the helpful owner’s manual that came with your car for this reason. The size of the battery your automobile needs should be specified in the manual. If you don’t buy the correct battery size, it won’t fit into the battery tray properly and could generate vibrations that could harm the battery.

You can find the kind of battery your car needs in the owner’s manual. This will assist you in selecting one with appropriate terminal placements. You can check up on your vehicle on the in-store fit guide if you can’t locate your owner’s manual.

Battery Freshness

A code consisting of a letter and a number on the battery serves as a sign of the battery’s freshness. The letter denotes the month and the number, the year of manufacturing; for example, B/4 denotes February 2014. Never purchase a battery that has been manufactured more than six months ago.

Reserve Capacity

In addition to ensuring that your battery will fit properly in your vehicle, it’s critical to consider the brand and model’s performance. Look into the year’s best-performing batteries. Make sure you choose a brand and model that has received a decent grade because this can change from year to year and size to size.

A battery with a good reserve capacity is another option. This is the period of time a battery can function without the assistance of an automobile. If you fail to switch off the lights, having a large reserve capacity can keep your automobile from dying.

Power requirement

The terms Cold Cranking Amps (CCA) and Cranking Amps were used (CA). Cold Cranking Amps refer to the battery’s capacity to start a car at 0 degrees Fahrenheit while Cranking Amps refers to the energy needed to start a car at 32 degrees Fahrenheit. Batteries with a greater CCA are advised for use in cold areas.

Maintenance

There are two varieties of car batteries. There are batteries that require little or no maintenance. Because they are sealed, maintenance-free batteries don’t require regular replacement of the liquid electrolyte.

The low-maintenance batteries feature unsealed caps and call for the periodic addition of distilled water. Every six months, batteries that require maintenance must be serviced. Without routine maintenance, they can stop functioning, necessitating the purchase of a new battery. Keep it easy and buy a battery that requires no maintenance if you want to save the extra worry.

Warranty

A warranty is another thing to consider when buying a new car battery. Pick a battery that allows for free battery replacement and has a longer guarantee. There will probably be a prorated term in addition to a free replacement period. This enables you to get a portion of the cost back for a specific time frame.

Types and position of the terminals

The polarity of the car is affected by the positive terminal’s position, and there is a chance of a short if the positive terminal makes contact with the metal car body. Due to this, it is essential to determine whether the positive terminal is on the right or left side of the car depending on the model.

Ampere hour (Ah)

This is referring to the battery’s capacity to store electricity (capacity). A battery with a larger Ah rating can support a load for a longer period of time, reducing the likelihood that it will run out of power.

Battery life

At an auto parts store or battery specialist, you may find out how long your current battery will last. This will enable you to determine whether you simply need maintenance or a new battery.

Previous experience

Consider your own prior knowledge of the battery type before making a battery purchase. It is ideal to have a battery that lasted a long time without giving you any problems, and you can always discuss this with friends.

How to test for a good car battery?

The followings are the three ways of testing for a good car battery:

  • Cold-cranking amps
  • Reserve Capacity
  • Battery life

Cold-cranking amps

CCA, or cold-cranking amps, gauges how efficiently a battery starts an engine in extremely cold temperatures. Batteries are cooled to 0° F in a freezer to simulate a winter environment, and their performance is then evaluated.

Regardless of what the manufacturer may claim, we believe that our CCA test is based on more realistic charging voltages and amperage demands than normal manufacturers’ testing, and our results demonstrate each battery’s relative cranking capability.

Reserve Capacity

Reserve Capacity describes how long a battery can power a car if the alternator, stator, and rotor stop working. It also serves as a gauge for how long the headlights can unintentionally remain on before needing to be jump-started.

Our engineers measure the time it takes a completely charged battery to be discharged down to 10.5 volts, which is regarded as being entirely discharged, in order to test reserve capacity. The automobile won’t start without a jump start at that point. We consider an average day to have 1½ hours of power. Higher-scoring models can continue to provide power for a lot longer.

Battery life

Each battery is discharged and recharged over 3,000 times over the course of 15 weeks at a test temperature of 167° F, or until performance deteriorates to unacceptable levels.

This simulates the sweltering under-the-hood temperatures a battery could experience in the summer, which is the hotter season of the year for batteries. Frequent high temperatures are especially hard for batteries because they accelerate the vaporization of the electrolyte required for current and increase plate corrosion. If you frequently take short trips with little time for recharging, long life is important. The battery’s reliability will increase with a score.

 

In summary

As a driver or car owner, maintaining your car parts are necessary so as is the powering battery. Buying a new battery is inevitable as long as the previous battery will certainly be due. This is why this article is here to guide you on things to consider when buying a new car battery.
