How to choose the perfect battery for your car?

Your car starting slowly or with trouble is the surest symptom of battery failure. The starter is powered by the battery and has to crank the engine against the pistons’ compression. Powerful vehicles, especially those with diesel engines, are needed for this. A jump start can help worn batteries recover momentarily, but a battery that requires multiple jump starts is beyond repair.

Avoid taking any chances. Avoiding the stress of a breakdown on the road or in a parking lot is well worth the small cost of replacing the battery. Batteries for cars and trucks come in two varieties: traditional lead-acid or the more modern absorbent glass mat (AGM) type, which is frequently used in vehicles with engine stop-start systems. Check the label on the current battery or refer to the owner’s manual provided by the manufacturer if you are unclear about the size, amp-hour rating, or cold-cranking amps required for your vehicle.

How to choose the best battery for your car?

The followings are the ways to choose the best battery for your car:

  • Be proactive
  • Test the battery manually
  • The battery should fit your car and its driving needs
  • Ensure it is a brand new battery
  • Recycle the old battery
  • Compare warranty
  • Pick the best battery life
  • Go for the longest battery car warranty


Be proactive

You can choose a replacement on your own terms, including thoroughly studying and conveniently scheduling, if you are watchful of your battery’s upkeep and aware of when the time for replacement is near.

Test the battery annually

Inspections ought to be a regular component of an owner’s upkeep, but it’s crucial to check before a protracted road trip. According to AAA, car batteries normally last between three and five years, varying from 58 months or more in the most northern regions of the U.S. to less than 41 months in the southernmost ones.

We advise getting your battery load-tested by a mechanic once a year once it is 2 years old if you live in a warmer area or 4 years old if you live in a colder environment, even though practically all of today’s automobile batteries are “maintenance-free.” By doing so, you can determine when it’s time to start shopping by testing the device’s ability to maintain voltage while in use.

Another clear sign that a replacement is needed is the battery’s age. The date is written on a sticker that is attached to the battery’s top or side. An October 2021 battery will have the numeric designation 10/21 or the alphanumeric code K-1. January is “A,” and February is “B.” And so on, although I am not included.

The battery should fit your car and its driving needs

There are several sizes of car batteries. There is a substantial variance among those we evaluated in terms of which performs best from year to year and size to size. Simple brand or model recommendations are therefore impossible. Additionally, it implies that you shouldn’t rely on the battery model you are changing when you buy a new one to produce the same outcomes.

Ensure that the terminal locations (or type) and size you choose are appropriate for your car. Before making a purchase, see your owner’s handbook or a retailer fit guide.

To increase longevity in hot regions, owners may occasionally swap out an AGM battery for a conventional flooded cell, but it’s recommended to get advice from a repair first. To support an expanding number of electrical components, many cars come equipped with AGMs, and the charging mechanism may be tailored expressly for an AGM battery.

Ensure it is a brand new battery

Even when stored, batteries gradually lose power. Buy one that is under six months old for the best performance. Even best is three months. The majority of cases contain a shipping code. Others use a numeric date, while some use a letter for the month (“A” for January) plus a number (“1” for 2021).

Recycle the old battery

The hazardous lead and acid in batteries may be easily recycled, and the majority of merchants will dispose of your old battery for you. You will probably pay an additional fee when purchasing a new battery at a store, which fee will be reimbursed when you return the old battery.

Compare warranty

It’s crucial to pick a battery with the longest possible free replacement term. The free-replacement duration and the prorated time—which only permits half reimbursement—are the two statistics used to measure a battery’s guarantee. For instance, a number of 24/84 denotes a prorated warranty of 84 months and a free-replacement period of 24 months. However, once you enter the prorated period, the amount you’ll get repaid typically decreases rather quickly.

A warranty may be voided if there are indications of negligence, such as low water levels and poor installation. If the battery is not suggested for it, heavy-duty use, such as for high-end automotive audio and marine applications, might also damage the battery.

Pick the best battery life

A battery that won’t make you return to the shop is what you want. Not all batteries are made equal when it comes to longevity.

By routinely charging, automobile batteries extend the life of your vehicle. Unfortunately, some batteries struggle to handle this constant infusion of fresh energy. With each recharge, the power of these batteries drops until they are effectively useless within the vehicle. Visit How Does A Car Battery Work? for more information on how batteries function.

Compare battery life, reserve capacity, and cold-cranking amps test results if you’re concerned about how long your new battery might survive. The most crucial test is the battery-life test, which evaluates a battery’s capacity to resist repeated recharges over the course of several months.

The reserve-capacity test gauges a battery’s ability to continue generating power even if its charging method malfunctions. Finally, if you reside or drive in a cold region, you should take the cold-cranking amps test. To ensure you won’t become stranded in below-freezing temperatures, it measures the current available at 0 degrees Fahrenheit.

Go for the longest battery car warranty

A battery with a guarantee is what you want. A strong warranty not only shows the manufacturer’s faith in the goods, but it also works to safeguard you in case something goes wrong.

If all else is equal, you want the battery that offers the freest replacements. A free replacement period and a limited performance warranty are the two main components of most battery warranties. Although you might receive a portion of your money back during this time, the amount you’ll receive in the event of a battery failure won’t be as much as with a free replacement warranty.

Check the battery’s condition and whether it is still covered under warranty. Some warranties may be nullified by neglectful behaviors like low water levels or poor installation. You might spare yourself a hassle (and a large price) down the line by having one of our skilled experts install your new battery and keep it working smoothly with routine maintenance.

How long does a car battery last?

For three to five years, car, truck, and SUV batteries are usually at their best. After that, however, they start to degrade and lose charging capacity, eventually leaving the vehicle’s engine unable to start. Owners of vehicles should routinely inspect the state of their batteries.

It’s best to test at least once a year after three years. Every oil change should include a thorough examination of the battery and its connectors. It can be time for a replacement if a vehicle battery test reveals degeneration or if the lights or electronics are displaying signs of aging, such as seeming dull.

How do I know if I need to change my car battery?

It’s probably time to replace your battery if the battery charge warning light on your dashboard illuminates or if the starter motor starts the engine over slowly. When the automobile is idle, low incandescent headlights are a sign of a poor battery in older vehicles.

Alternately, rev the engine while in a park or neutral if your car’s headlights seem faint at night. The car’s battery is probably deteriorating if the headlights get brighter as the engine revs. A new alternator, which is the component that charges the battery while the engine is running, may be required if you install a new battery and discover that it quickly goes dead.

Why does my car battery lose charge?

Batteries produce electricity through an electrochemical process using the chemical energy they have stored. There is a limited number of charge and discharge cycles before a battery’s ability to store energy and deliver its maximum power start to deteriorate.

Batteries will deteriorate more quickly in cold and hot temperatures, but any unused battery will deplete (as many office-commuting drivers learned in 2020). Vehicle batteries that are only utilized for short excursions might never get the chance to fully recharge, which simply has the effect of hastening battery aging. Other elements can seriously damage batteries, including vibration from bumpy roads or loose hardware, a broken vehicle charging system, and humidity.

What type of battery do I need? How many cranking amps are necessary?

The battery type, group size, terminal arrangement, and cold cranking amps (CCA) or amp-hour (Ah) rating must all be taken into account when selecting the best battery for your car. The group size is determined by the model and engine type of your car, taking into account the battery case’s external dimensions and the battery terminal’s orientation.

Each battery has a group number that may be seen on the top or side of the case. Make that the new battery’s CCA or Ah complies with the requirements set forth by the car’s manufacturer and that the group size number matches that of the battery in your current vehicle. If the terminal placements result in a short circuit with surrounding components, for instance, installing the wrong battery could harm the car’s electrical system. If you are unsure about the battery to buy, consult the owner’s manual for your car.
