Best Car Battery: Buyers Guide

Battery Type

There are a number of different car battery technologies out there. Standard lead-acid (SLA) and absorbed glass mat (AGM) batteries are the most common. Lithium-ion batteries are also becoming more common for cars.

  • Standard flooded lead acid : This is the most common type of car battery. The battery contains liquid battery acid and will require more maintenance than an AGM or lithium-ion battery. This type of battery is most common in older vehicles (pre-1980).
  • Absorbed glass mat : An absorbed glass mat battery is highly vibration-resistant, non-spillable, and maintenance-free. Battery acid is absorbed in fiberglass mats, which prevents leakage or spillage. This type of battery offers a superior lifespan to standard flooded batteries and can handle large power demands. It is the most common type of car battery in modern vehicles.
  • Lithium-ion : Lithium-ion batteries can be much smaller and lighter than AGM and SLA batteries. They offer a very fast charging rate and are maintenance-free. This type of battery tends to outlast AGM batteries.

Choose a battery type that matches your existing battery. AGM batteries are the most common type of car battery. If you replace an AGM battery with an SLA battery, your car may not start or function properly.

Group Size

Your car battery rests in a specifically sized battery box. If your replacement battery is too small, it won’t be properly secured. If it is too big, it won’t fit in your vehicle. In addition to battery dimensions (length, width, and height), terminal location is also critical to proper fit.

Fortunately, you won’t need to get out the measuring tape to match battery dimensions. All batteries should have their group size listed somewhere on the label. This is typically a two-digit number. You can also check your owner’s manual, which may list the group size, or try searching Google for your group size based on your vehicle’s make, model, and year.

Below are some common group sizes:

Group Size Common Vehicle Fit

Cold Cranking Amps (CCA)

CCAs refer to a battery’s ability to turn a cold engine. The higher the CCA, the more powerful the battery. As with group size, your current battery’s CCA should be listed somewhere on the battery label.

Each car is engineered with the factory battery CCAs in mind, which is why it’s a good idea to match the CCA of your current battery – rather than attempt to “upgrade” your battery to one with more CCAs, as this can lead to decreased battery life.

Reserve Capacity (RC)

Reserve capacity refers to a battery’s ability to keep essential car accessories powered after a vehicle’s alternator fails. With more and more cars using computers and battery power for essential systems, RC has become an important battery feature.

As with CCA, try to match your new battery’s RC with the original battery. If you choose a new battery with a lower RC, it could fail to properly power your car’s critical systems.


Once you’ve found batteries that match the specifications of the one you are replacing, consider batteries with longer warranties. These are guarantees that you won’t have to shell out for a replacement within the warranty period.

Most car batteries come with at least a one-year warranty, but some offer warranties up to three or four years long.

Car Battery Replacement Tips

If you need to replace a dead battery, you can take it to an auto mechanic for diagnosis. A mechanic will have the tools to diagnose and quickly change your car battery. Labor costs for battery replacement can range from about 37 to 47, according to RepairPal. That said, those costs don’t account for the type of battery you’re purchasing.

If you’d prefer to change your own car battery, this is possible for a layperson, though it can be an involved procedure. Specifics may vary from vehicle to vehicle, as battery positioning is not the same for every car. Search for guide videos specific to your vehicle’s make and model or start with our general guide on how to disconnect a car battery.

Whichever type of car you have, there are some tips to keep in mind when performing an at-home car battery replacement.

  • Put safety first. Modern AGM and lithium-ion batteries are mostly safe to handle, but SLA batteries can slosh highly corrosive acid that will damage your skin and eyes. Wear proper safety equipment including goggles, long sleeves, and gloves when handling a car battery. It’s also a good idea to keep some baking soda handy, as it can be used to neutralize any spilled battery acid.
  • Keep your car’s memory alive. Modern vehicles are highly dependent on computers to operate major and minor systems. When you disconnect your car battery, it can turn off the computer, effectively resetting the onboard computer. This can cause some systems to work improperly until they are reset. Some cars will reset automatically after a few weeks, while others may require hours of diagnostic fiddling to restore. You can prevent this hassle by using a power supply cable to keep your computer powered while you replace the battery.
  • Be gentle. Don’t attempt to smash or roughly shove your battery into place. The same goes when attaching the terminal clamps. If your terminal clamps are too tight, use a terminal spreader to widen battery terminals rather than banging on your battery to force them down.
  • Recycle. Car battery recycling must be done at specific locations. Check your city website to find guidelines on hazardous waste disposal. Many offer dropoff or pickup services. You can also recycle old batteries at certain stores. Advance Auto Parts and AutoZone both offer battery recycling services. These stores also offer free battery testing.

How Much Should Car Batteries Cost?

Newer car batteries that have higher CCAs and use advanced technology are going to cost more than replacement batteries for older vehicles. While more expensive, these batteries also tend to last much longer, so can be cheaper in the long run.

battery, finder, auto, guide

In general, you can expect to pay anywhere from 150 to 500 for a new car battery. SLA batteries are usually the least expensive, followed by AGM batteries. If you choose a lithium battery, you might pay upward of 1,000.

Depending on the CCA, RC, and group size, the same model battery can vary in price up to 100.

Why Do Car Batteries Go Bad?

Car batteries fail due to multiple factors ranging from neglect to old age. Below are a few examples of what causes batteries to die.

  • Temperature : Climate is probably the greatest opponent your car battery will face. Even the best car batteries can struggle to crank in extreme temperatures, so more temperate climates typically mean a battery lasts longer.
  • Minimal Use : Having a car sit idle for a few weeks or months will usually result in a dead battery. That’s because it is not utilizing enough of the car’s charging system, which depends on the car running, to recharge.
  • Vibrations : If a car battery is not properly secured in the engine bay, vibrations from the vehicle can cause it to deteriorate and shorten battery life.
  • Corrosion : Corrosion occurs as chemicals naturally escape from the car battery and mix with air and water in the engine bay. As corrosion accumulates, it can weaken the connection of the battery terminals.

If your car battery failed within two to three years of purchase, check the parts store’s replacement warranty, they may offer a free replacement. For details on how long car batteries last, check out our informational guide.

Recreational Battery Buying Guide

No matter how well you take care of the batteries in your RV, you’ll eventually need to replace them. We’re here to help make sure you end up with exactly what you need.

Why Do RV Batteries Fail?

There are plenty of reasons why your recreational vehicle battery might need replacing. Interior corrosion, for example, can lead to failure. Leaving the battery at a low state of charge, connecting it incorrectly, or using the wrong type of charger can also cut its life short.

Even extremely hot or cold temperatures, which aren’t uncommon throughout most of Canada, can cause a lead acid RV battery to fail. You should keep this in mind if you spend your winters somewhere warm, like Arizona. Excessive vibration from driving on rough roads can reduce the lifespan of the battery as well.

That said, the two main reasons why starter batteries, deep cycle batteries, marine batteries, and even absorbed glass mat (AGM) batteries will fail after a few years are sulfation buildup and paste shedding.

Sulfation and Shedding

Sulfation happens naturally when sulfates in the battery acid crystalize on the lead plates. Over time, this process causes the sulfate levels in the liquid electrolyte to decrease, reducing the battery’s ability to hold a charge.

Paste shedding is caused by natural expansion and contraction. It refers to the shedding of lead paste off the plates in the battery. As the plates lose lead, the battery loses power.

Replace Batteries in Pairs

Lots of RVs, especially bigger ones, have more than one battery. If yours does and it’s time to replace one, you should probably replace them all.

Yes, replacing multiple batteries can be expensive, but think about it this way: the other batteries have also been affected by whatever caused the first battery to fail, so they’re probably close to failure as well.

If you replace only one battery, it might get damaged by the others since they aren’t at a hundred percent, which means you’ll need to replace it all over again—along with the rest.

Unless the single battery that failed is still under warranty, it’s probably time for a whole new set.

Check Your Voltage

Most recreational vehicles use 12 V lead acid batteries, but some have a 6 V battery. Two 6 V batteries connected in parallel amounts to 12 V, but with potentially more amp-hour storage. Make sure your replacement battery has the same voltage as the old one.

House or Vehicle Battery?

Many RVs have two different electrical systems with two different types of batteries: house batteries and the truck battery. The house batteries are used to power electronics in the RV.

House batteries are usually deep cycle 12 V batteries. They’re long-lasting and capable of deep power discharges—exactly what you need for a couple of days of off-grid camping.

The truck battery is going to be a starting battery. These are batteries designed to be able to put out lots of power for the short time your starter is running. Then, your engine’s alternator takes over power and charging.

A truck battery is just fine being charged by the alternator. The charger on your deep cycle house batteries charges much more slowly. The two batteries can be switched, but doing so typically results in short battery life and other problems. You should also keep in mind that solar power charging is usually slow.

Ultimate Car Battery Guide: How to Charge, Maintain, Replace, and more

Your car battery plays a vital role in your vehicle’s operation, but if there’s a problem, it’s not always easy to know what it is. There’s a difference between recharging an otherwise healthy battery and replacing a depleted one. Either way, it’s important to know the proper course of action and get to the bottom of the issue. This guide will teach you essential information about checking, charging, boosting, and replacing your car battery.

If gas is the lifeblood of a car engine, the battery is the pulse that keeps it going. There’s no worse feeling than buckling up to drive somewhere and twisting your key in the ignition only to hear a clicking sound, and then silence. A boost may help jumpstart it again, but what if your battery has simply reached the end of its lifespan and needs to be replaced?

The good news is, it’s easy to keep tabs on your car’s battery life if you know what to look out for. We’ve compiled a few checklists and step-by-step guides to help you check, charge, boost, and replace your car battery.

How long do car batteries last?

Not everyone agrees on how long a car battery will last for. Conventional thought is about four years, but some people will tell you that up to six years is possible.

The lifespan of your battery depends on a number of factors:

  • Canada’s harsher climate, with colder winters and hotter, humid summers mean the battery’s overall capacity could drop.
  • Vibration is also an enemy of battery longevity, and you need to make sure your car’s battery is securely fastened under the hood with all the necessary brackets and bolts.
  • Using in-car electronics can also tax the battery because so many features need power. Windshield wipers, headlights, heating/AC, car stereo, GPS navigation, backup cameras, and assisted driving functions, among others, all work off the battery.
  • Voltage recharge rates can also play a role. Like fast smartphone charging where a large chunk recharges in a shorter time with the rest staggered out over a longer period, car batteries don’t hit 100% capacity automatically. For example, it may take seven hours to recharge up to 80-90%, and then take several hours to finish off the remaining 10-20%.

For that reason, shorter driving distances done frequently could actually reduce the long-term battery power sooner. This can also happen with “undercharging” caused by increased corrosion or leaving lights on overnight, for example. Constant undercharging leads to acid stratification, where the battery stays at a lower charge (below 80%) and never gets fully charged.

When should you replace a car battery?

It’s hard to truly gauge a battery’s health from the outside, but that doesn’t mean you can’t glean at least some insight into it. One of the telltale signs that something isn’t right is a slow crank. When you hear the car wheezing during ignition, especially when the weather isn’t cold, something might be amiss.

That may be caused by a weakened alternator not charging the battery fast enough, so it may not be the battery, specifically. But there are a couple of checks you can do that will help you determine whether you need a new battery soon or not.

If the problem is with an old car and not an old battery, Canada Drives can help find a great deal on a certified used vehicle!

How to check your car battery for damage

A good rule of thumb is to start inspecting the battery more frequently after three years. There are two checks you should do: an eye test and a load test.

The eye test

The eye test is simply a visual inspection when you lift the hood. Look for corrosion around the cell connectors or posts holding the battery, cracks on top of or down the side of the battery, a fraying or broken cable, or unusual stains. Any of these signs indicate your battery might need to be replaced soon. Also, a smell of sulfuric acid should not be ignored. This diagram highlights which parts of the battery should be checked during a visual inspection:

The load test

You can do a load test to gauge capacity and charge with a handheld multimeter (or voltmeter), which you can pick up at almost any hardware or automotive store:

  • Set the multimeter to 20 DC volts.
  • Lift the hood and match the prongs to the negative (black) and positive (red) terminals on the battery.
  • Push the start button. You don’t need to turn the car on yet.
  • What you’re looking for is a reading that maintains 9.6 volts. If it hits that mark and then steadily drops, that’s not a good sign. If it immediately drops to zero, that’s also a problem.
  • Turn on the engine and look for the measurement to hit 12.6 volts or so. If it’s lower than 12.2 volts or higher than 12.9 volts, then your battery either needs a slow charge or the removal of excess charge.
  • You can remove the excess charge by connecting your high beam headlights.
  • If your battery is undercharged, you can also trickle charge with an electric cord with a plug and two jumper cables with alligator clips to latch onto the negative and positive terminals. When it comes to long-term health, a slower charge benefits a battery more than a faster one does.

If it seems like your car battery is consistently losing its ability to hold a charge over time, it might be time to buy a new one.

How long does a car battery last without charging?

Picture yourself parked and waiting in the pick-up line, waiting for your kids after school. Since you can’t idle, you’re listening to the radio when you lose all power. The battery has died.

It could be in various situations – waiting in line for a ferry, leaving the lights on, or leaving a charger plugged into the power outlet. How long will your car battery last without starting the engine to charge it?

The answer varies depending on several factors:

  • The age and condition of your battery
  • Your battery’s style and design, including its reserve power
  • The power demands from your accessories

A normal radio could play literally all day and your battery will still have the necessary power to start the engine, as is the case with most charging accessories inside. An amplified radio or a newer vehicle with a large infotainment screen might have only an hour or two in reserve.

If you’ve left the lights on, how long your battery lasts depends heavily on whether it’s your headlights or interior lights, as well as if they’re normal halogen headlights or LED lights. It can range from just 30 minutes to several hours with headlights, and even days with the interior light left on.

If your battery dies after listening to the radio for less than an hour or a light left on kills the battery quickly, there’s a good chance it isn’t holding a full charge anymore and needs to be replaced.

How to jump-start a car battery (with booster cables)

Even if your car battery isn’t old, has no corrosion, and is securely connected and fastened, it may still die on you from time to time. There could be a number of reasons for this. Maybe you left the lights or car stereo on for too long while the engine was off. Or maybe the car sat inactive for too long.

If your battery problem isn’t actually a malfunctioning alternator, there are a few things you can do to jolt your car back to life. The first is a jumpstart with booster cables. You’ll need booster cables (obviously). You’ll also need a friend or helpful passerby to volunteer their car for your battery-boosting cause.

  • Make sure to park the functioning car close enough to the dead one so the cables can reach.
  • Connect the red or positive cable to the positive terminal on the dead battery, and then do the same on the other end with the working car’s battery
  • Connect the black or negative cable to the negative terminal on the working car’s battery, and then clamp the other end onto an unpainted metal surface, like the metal strut holding the hood open, or another exposed strut under the hood.
  • Start the working car’s engine and let it run for a few minutes. After that, try starting your car.
  • If the engine turns on, keep it running or drive around for about 15 minutes to let the alternator recharge it.
  • If your battery repeatedly dies on you, and there’s nothing wrong with your alternator, you might need to replace your battery.

How to revive a dead battery without booster cables

Besides getting a jump from another car, there are a couple of other ways to revive a dead battery. A battery charger is a handy device to keep on hand when you don’t have booster cables or another vehicle to draw power from.

Using an automotive battery charger

An automotive battery charger connects to your battery in the same way jumper cables do. Simply connect the red clamp to the positive terminal, and then the black clamp to the negative one. Plug in the battery charger to a power outlet. Chargers can also retain a charge with their own battery, letting you use them on the go as well.

These videos by are a great reference on how to charge your car battery with a battery charger.

Step 1: Lift the hood of your car and uncase your battery’s terminals.

Step 2: The red clamp attaches to the battery’s positive terminal and the black clamp attaches to the negative terminal. After you connect to the terminals, plug your charger in and turn it on.

Step 3: When your battery is charged, disconnect the charger by removing the black clamp first and then the red clamp.

How to push-start a car with a dead battery (aka bump start)

If you don’t have any booster cables or a battery charger, a couple of willing friends will help you push-start your car. The faster your friends can push the car above 8km/h (with you in the driver’s seat), the more likely the engine will start when you depress the clutch and switch the ignition on. Here’s a great YouTube video by on how to do this:

How to make your car battery last longer

Car batteries can be expected to need replacement eventually, and a high-quality battery to fit your vehicle isn’t always inexpensive. But there are things you can do to make it last as long as possible.

  • Don’t let it become completely discharged. Letting your battery fully discharge is sure to take away from its normal life expectancy.
  • Remove your car battery when it’s in storage. If you don’t plan to drive your car for at least two weeks, disconnect the battery to prevent normal draws from killing the charge. Or, put it on a trickle charger until you’re going to use your car again.
  • Service your battery annually. That includes cleaning corrosion from the terminals, checking and topping up the battery electrolyte fluid if necessary, and charging the battery to full capacity.
  • Make sure your battery is securely clamped down to prevent damaging vibrations.

How to replace the battery

After you’ve determined that your vehicle battery is ready for retirement, the following steps will help you swap out your car battery by yourself:

  • Make sure the vehicle is off and the parking brake is applied.
  • With your smartphone, take a photo of the battery compartment before you remove it. Having a photo will help you remember exactly how to reconnect the new battery.
  • Disconnect the black (negative) cable first. Then, disconnect the red cable.
  • Use a wrench to remove the battery restraint, sometimes laid out as a bar on top or clip holding it in place at the bottom.
  • Remove the battery, and keep it steady without tilting it when lifting it up.
  • Install the new battery by reversing the uninstallation steps.
battery, finder, auto, guide

Properly dispose of the old lead-acid battery by taking it to a store that sells new car batteries, like Canadian Tire, Costco, Walmart and other auto parts locations. There is no municipal recycling pickup for used car batteries.

Do you need to charge a new battery before use?

When you buy a car battery, it typically comes sufficiently charged to start your vehicle, to around 90% of capacity or so. It isn’t required to charge a car battery before its first use.

However, under normal driving conditions, the alternator is unlikely to charge your battery to full capacity. It keeps it sufficiently charged, but fully charging a new battery if you have the time to do so will ensure you get the best life expectancy from your new car battery.

How much does it cost to replace a car battery?

Car batteries range in price from under 100 to over 400. You can find them at various retailers, like Canadian Tire, Costco, Walmart and auto parts stores. Be sure to have your car’s make, model, engine size, and battery dimensions handy when picking one up.
