- How long will a car battery last?
- Do I need a “heavy-duty” car battery?
- What kind of car battery do I need (e.g., absorbed glass mat over the flooded cell)?
Ultimately, it’s your answers to these questions that determine what car battery you should buy. Take your time and be an informed consumer. Happy buying!
Criteria Used in Evaluation
Of The Best Car Batteries in 2018
Before evaluating the best car batteries online, we took the time to put together some criteria that we used to judge each product. Buying a car battery is an involved process, but we were able to boil it down to four important feature types that can help you make your next buying decision. Primarily, those include:
#1: What niche features do they offer?
Are you an everyday commuter or looking to power your next off-roading expedition? Different vehicle types demand their car battery features. Some common niche features include:
- Vibration resistance for use around heavy machinery
- Solar charge capability for the eco-minded consumer
- Easy-start design for use in cold temperature extremes
- High conductivity for strong connections that need to handle huge electrical loads
More features don’t always make a car battery automatically the best. Instead of going for the most feature-laden battery, choose a battery that has the niche features that fit your lifestyle. If you live in Arizona, then that easy-start design feature isn’t so useful. Pick features wisely to get the most out of your car battery purchase.
#2: What technology do they use?
Car batteries come in a wide variety of designs, relying on techs such as absorbed glass mat (AGM), lithium-ion, or wet flooded cells to produce energy. Wet flooded cells are the most inexpensive of the lot, but they’re also the most likely to run out of a charge prematurely, or even fail. Durable alternatives include lithium-ion, AGM, valve-regulated lead-acid, and more.
Nearly all of the premium batteries on this list feature absorbed glass mat designs. That’s simply because this design type is sturdy and puts longevity first, so you get the most out of your car battery purchase. AGM is also cheaper than other premium techs, meaning you pay less.
#3: Does it fit the budget?
Premium batteries come with a premium price tag, but there are plenty of feature-rich alternatives at moderate and even budget prices. We’ve taken the time to feature a wide variety of batteries from different price points, so whether you need a budget car battery or a super performance powerhouse, you’re covered with this guide.
Are cheap car batteries good?
You might be tempted to go full budget and save some money. A $50 car battery looks appealing compared to a $250 car battery, but there are big differences that are more important than the price tag. With car batteries, it’s quite true that you get what you pay for, although we’ve featured a few brands here that offer good budget choices.
Why stay away from most cheap car batteries? The vast majority of them use old technology and don’t last for as many cycles or discharges as pricey batteries can. The difference in price is normally chalked up to differences in technology, and today’s premium-priced batteries are very much worth it.
Is it worth paying more for expensive car batteries?
Probably. But it all depends on your car and your needs.
For an everyday commuter car, a basic (but high quality) battery like the Optima RedTop is a solid choice that won’t break the bank.
On the other hand, if you’re into hobbies that are plain hard on your vehicle, then you might need something heavier like the ACDelco Professional.
Check out your situation and decide what’s a priority for you. You might find that you would appreciate a premium car battery more than you thought!
#4: What are the cycle and discharge times?
To understand a bit about cycle and discharge times, you need to have a basic idea of how batteries work. Here’s what you need to know, starting with battery cycles:
What’s a battery cycle?
Batteries hold energy and facilitate their discharge when needed. Generally, a battery “cycle” is the process of the battery charging with energy, then discharging the power to empty while it’s in use.
The phrase “cycle times” can be a bit inconsistent. Some use it to mean the amount of time it takes for a battery to fully charge from zero to 100.
Others use it to mean the battery’s total lifespan: the number of times you can fully cycle it from empty to full to empty again before it fails. This is the most common meaning of the phrase and the one you’ll encounter most often when shopping for car batteries.
What’s a battery discharge?
For a battery to discharge means to expend energy while it’s in use. “Fully discharging” a battery is a phrase that car owners come across often in reading about car battery tech and maintenance. To discharge a battery means to drain it until it’s fully devoid of energy. There are typically troubleshooting or repair reasons for doing this procedure.
In car batteries, the battery’s discharge rate might be listed. This discharge rate refers to how long it can last with continuous use before needing to recharge.
What do cycle and discharge times mean?
Longer cycle and discharge times are always better. They indicate that batteries will last longer between charges and that they’ll hold a charge better when not in use. It also means that they’ll have a longer overall lifespan. In general, you’ll get the most for your money.
We’ve selected batteries with long cycle and discharge times wherever possible, in favor of efficiency.
Need help understanding your car battery purchase, but aren’t quite sure what you just read? Car terminology can be challenging if you don’t have a mechanical background, but no need to worry. This list of car battery terminology can help you understand so you can make the most informed purchase, whether you’re a total novice or an expert under the hood. Check out our expert definitions:
What is an absorbed glass mat battery?
Absorbed glass mat batteries are built using technology that maximizes the electrolyte surface area. Thin glass fibers are contained inside the battery, providing massive amounts of surface area for the electrolyte to hold on. Because the electrolyte is what allows the battery to attract and hold a charge, this significantly increases performance.
What’s a battery clamp?
Battery clamps are adjustable, lightweight aluminum connectors that are used to attach connections, either when installing a battery or when jump-starting it. Every car owner should have a set of clamps on hand when buying a new battery.
What is battery cycling?
Battery cycling is the process of a battery filling with energy, and then discharging it fully; or the process of a battery going from empty, to full, to empty again. Batteries typically have a limited number of cycles before they fail.
What is the battery discharging?
Discharging is when the battery redirects stored energy into the device that it’s powering. The battery loses charge. Batteries can also discharge unexpectedly without actively powering a device, such as when a car is powered down in the cold.
What’s a car battery terminal?
A car battery terminal is the point of connection between the battery and the device or vehicle that it’s powering. These are attached using cables and clamps. The standard build for car batteries is to have the negative terminal on the red side, and the positive cable on the black side. This color-coding makes it foolproof to install a new battery.
What is a lithium-ion battery?
Often abbreviated as LIB or Li-ion, this type of battery uses lithium ions to move energy during use and when it’s charging. This type of battery is widely beloved for its rechargeability and efficiency, but it’s not available for most cars on the market as of 2018. Hopefully, shortly!
What is a flooded cell battery?
A flooded cell battery uses water and electrolytes to conduct electricity. Water attracts and moves energy from the positive terminal during charge, to the negative terminal during discharge. The benefit of this type of battery is that it’s cheap. The downside is that it invites corrosion early on, and these batteries don’t tend to last longer than a year or two.
Frequently Asked Questions
About Car Batteries
What kinds of car batteries last longest?
Deep cycle car batteries tend to be the longest-lasting in terms of holding a charge. This type of battery is lead-acid, and it’s designed specifically to discharge with heavy use regularly. Their connective plates are packed less densely and are made of sturdier metal, which means stronger electrical signal. If you buy a deep cycle battery, you can get the most out of it by regularly measuring the depth of discharge and keeping it around 45 percent.
Lithium-ion car batteries are the longest-lasting on the market in terms of lifespan, but they’re only available for compact cars as of 2018. In addition to being highly selective about which models they can work on, lithium-ion batteries also tend to be too expensive, so we haven’t included any on this list because they aren’t a good value.
AGM batteries are a good alternative for non-compact cars. Also, keep in mind that deep cycle car batteries are competitively long-lived, making them a good choice if you don’t have a compact car.
Are car batteries universal?
The short answer: no, car batteries aren’t universal. Car batteries come in 12V as a standard, but other details such as amperage matter, and can render a battery completely unusable if you didn’t double-check the compatibility. Two outwardly similar vehicles can have completely different electrical operating requirements, and ignoring those can lead to sudden failure.
Additionally, size can be a problem. Pickup trucks, for example, have a really large battery tray, which would never fit a battery intended for a compact car. Sometimes you can get around size problems by using external mounting brackets to modify the tray or bypass it altogether, but that doesn’t work for all batteries, nor all cars.
Always choose a battery that’s compatible with your car model. Most of the time, the manufacturer’s description of the product includes a list of compatible models, which you should be able to access and search before making a purchase. Double-check with a trusted mechanic if you’re not sure.
How do you pick a good car battery for cold weather?
Live somewhere, frigid? You need a solid car battery that can handle icy temps without failing you. Look for a car battery with deep cycling, which helps elongate the time between charges, and helps minimize passive discharge in the cold.
We’ve already talked a bit about deep cycling and what makes it a great choice for car battery tech. Some of the benefits of this particular use include:
- It resists sudden discharge, which can often be triggered by cold.
- If it does discharge due to extreme cold, it’s already built to handle that, and won’t fail prematurely because of it.
Our Editor’s Choice pick, the Optima RedTop, is a fabulous choice for the cold. In general, any deep cycle battery does a fantastic job at this application, and there are several represented on this list.
What’s the best way to take care of a car battery?
Most auto batteries these days are self-maintaining, so there’s no need to go through periodic discharge cycles to ensure its health, with the exception of deep cycle batteries that are built to do that. Discharging a non-deep cycle car battery too far in an attempt to increase its lifespan can kill it prematurely.
For the most part, your car battery should be left alone when it’s not in operation. Exceptions include long-term storage (remove the battery from the operation and store it in a cool, but not cold, dry place).
Even though you shouldn’t be taking your car battery out or doing anything to it regularly, a yearly checkup is a good idea and can help keep your battery in fantastic shape for longer. The steps include:
- Inspect the battery for corrosion and remove it using a battery cleaning agent, or a mix of lemon juice and baking soda.
- Check electrolyte levels, if it’s a flooded cell battery. If needed, you can add distilled water to raise the levels.
- Use a hydrometer to test each cell, which gives you an idea of the battery’s current efficacy.
- Reinstall clamps and cables. You’re done until next year!
