A Guide to the Best Car Batteries

By Yehudah Posnick

You need a properly-working car battery to start your car, as well as to operate the car’s lighting and radio. Also, some vehicles can employ a second car battery, that is dedicated to running the car’s stereo. And there are motorcycles and ATVs that are best with a non-standard, AGM (=Absorbed Glass Mat) battery.

A good car battery can last you anywhere from 3 to 5 years--but you certainly don’t want to push it to the end of its life, when you might be stuck somewhere and even jump-starting won’t help. When you find that you have to replace the battery, you should know what specs to look for.  There are also things to consider that will extend the life of your battery.

We’ve composed this buyer’s guide to help you make the right decision when selecting a car battery. It'll help you:

  • Choose the right type of car battery,

  • See useful tips about that particular type of car battery,

  • Read reviews of different car batteries, and what customers are saying,

  • Select the right brand of car battery, and

  • Compare prices and find the best deals.

Types of Car Batteries

Car batteries typically provide 12.6 volts, by using 6 cells in series. Each cell has two electrodes: the positively-charged anode, made from lead dioxide, and the negatively-charged cathode, which is made of lead. The two electrodes sit in a solution of sulphuric acid, which is the electrolyte, that allows for the reaction to take place between the anode and cathode. Each cell produces 2.1 Volts, which together is 6 x 2.1 Volts = 12.6 Volts. They are known as valve-regulated lead-acid (=VRLA) batteries. There are three principal types:

  • Flooded Sealed Lead Acid Batteries: These are also known as “low-maintenance” batteries. They have sulphuric acid in liquid form between the two electrodes.

  • Absorbed Glass Mat (=AGM) Batteries: These are called “dry” batteries, with a fiberglass mesh or mat that has absorbed the electrolyte. This has the advantage in that there is no risk of spilling battery acid. These batteries will be used in motorcycles and ATVs, since they may perform rapid turns which can cause the electrolyte to spill if using a flooded sealed lead acid battery. Also, these batteries will be vibration-resistant, such as the Kinetik HC600 Blu Series Battery.

  • Gel cells: These have silica dust in the sulphuric acid electrolyte, which turns it into a gel. They use a one-way valve to allow the battery’s internal gases recombine in the battery’s fluid. This type of battery also avoids the risk of spilling acid--which increases the versatility of how the battery can be mounted.

What Reviewers Say

  • Improving your car’s audio: If you want to power your car’s audio  system separately from the other circuitry in your car, you can try installing a second car battery. It’s recommended to buy two batteries, so that they work at equal strength. One will serve the function of powering the ignition and lights, while the other will power your car’s sound.

  • Matching the dimensions: It’s recommended to check the dimensions of the car battery and the tray where the battery will be held, to make sure that the battery is compatible. The tray size will depend on your car’s manufacturer. There are five different battery sizes, which vary among GM, Ford, Honda, and Chrysler cars. But buying the wrong size battery might damage your car if it’s not the right type. So this is something to be concerned about.

  • Battery power: If your battery is going to power a recreational vehicle, ensure that the battery is powerful enough to run the lights and appliances in your RV even when not traveling. Some notice that they can get 2-3 days of power from their battery, even without recharging it, as in the Mighty Max ML35-12 AGM Solar Battery.

Important Features

  • Signs of when to change a battery: When you turn on the ignition, but the car still won’t start without a jump start from another car, this could be a sign that the battery has died and can’t hold its charge, even after the engine runs for some time afterwards. Other signs of a dead (or dying) battery are:

    • When turning the ignition key, the engine doesn’t crank and the lights won’t go on,

    • The car will start only intermittently (although this could be an indication that the battery’s cables are not making a good contact),

    • You have to resort to jump-starting too often--such as 3 times a week.

  • Tips to preserve your battery: You never want to drain a car battery completely, like having your lights or radio on without the engine running. This can cause lead sulfate salts to crystallize on your battery’s electrodes, reducing its life considerably. It’s recommended to take note of any unintentional leaks of charge from your car’s battery (like when it’s difficult to start your car in the morning, even though you didn’t leave the lights on inadvertently). Also, trying to start a car in cold temperatures puts a greater strain on the car battery. You should also check the amount of sulphuric acid electrolytes in the battery in the summer months, to make sure that there is an optimal level of electrolytes.

  • Recycling: When a car battery no longer can retain a charge, it is required to recycle it, in order not to contaminate the environment with lead waste. 99% of the battery’s lead can be employed in other uses--and 80% of a new car battery will usually consist of recycled lead. You will get a credit towards your next purchase of a car battery when recycling the old one.
