We’ll also provide maintenance tips to keep your stock battery usable for as long as possible before you need to consult this car battery replacement guide to get another one.

Why You Need To Replace Your Stock Battery

Your car comes with a stock battery under the hood. This is the one provided for by the manufacturer, and it will serve its purpose for as long as it is within its specified operational lifespan. Since everything mechanical has a half-life, your stock battery has an expiration date. This can be shortened by several factors. Taking care of your battery is an excellent way to extend its lifespan.

Car batteries last for about three to four years. If you live in a tropical country, that lifespan can be cut in half.

To ensure your stock battery lasts longer, keep your poles clean and secure it to prevent damage caused by excessive vibration. Make sure you don’t completely drain your battery by turning everything off completely before leaving your car. Take note, dash cam systems also use part of the battery.

Lastly, check for signs of corrosion and replace your battery when it becomes evident that rust and oxidation have set in. you can spot this easily if you see white powder on top of the terminals.

Stock batteries are often just the regular kind or lead-acid. This does not mean it is automatically inferior to after-market batteries, but you’re eventually going to replace it once it expires. This car battery replacement guide will point you in the right direction to get the right one when that time comes.

Until then, save your money so you can buy these batteries:

Two Types Of Car Batteries

There are two types of batteries, Regular and Absorbed Glass Mat (AGM). 

Regular batteries are lead-acid batteries that are found in most cars today. This is because they are cheaper. But cheaper doesn’t necessarily mean low-quality. It’s just that you will eventually have to replace them at the end of their lifespan.

Absorbed Glass Mat (AGM) batteries have a better ability to withstand the constant charging and draining that occurs when it is in use. There are also smart features like electronic safety, convenience features, fuel-saving stop-start systems, and power outlets for mobile electronic devices.

Because of this, AGM batteries cost more than a normal lead-acid battery. But that price difference will ultimately pay for itself once you have one in your hands and under your hood.

Ok, now on to the list

The Top Four Batteries In Our Ultimate List

We initially had a list of a dozen car batteries for this ultimate car battery replacement guide. We then pared it down to half a dozen before ending the list with four of the best in the market today.

You’ll notice that we’ve mainly chosen AGM batteries. This is because

Odyssey PC680MJT

Odyssey is one of the leading car battery manufacturers operating in 17 countries all over the world. They supply batteries for commercial, industrial, and military use. Needless to say, their batteries are designed with top-notch quality.

Optima D35 Yellow Top

The Optima D35 Yellow Top is the favorite battery by car show winners. This is largely due to its clean appearance and ability to be positioned in any manner within the car for maximum aesthetic appeal.

But don’t let its small size fool you. This battery can deliver 650 cold cranking AMPS and has a slow discharge rate. Powering a large vehicle or storing it for a long time shouldn’t pose a problem for you. You can always make sure you’ll have a vehicle that’s ready to go with an Optima battery under its hood.

You’ll also find Optima batteries under the hood of most race cars because they don’t add too much to the car’s overall weight.

Tips On How To Choose The Right Battery For Your Car

And so we end this car battery replacement guide with a few helpful tips on how to choose the right one for your car. In the long run, selecting the right battery will help you save money. Taking care of your batteries will help you extend that investment even further.

Choose The Right Battery For Your Car

Let’s start with choosing the right battery for your car. You can find this information in your car’s manual. If you don’t have that, you can always consult with a professional mechanic. Or you could simply look at the information on your stock battery and ask a battery service center for an appropriate replacement.

You should also consider the climate you live in. If you live in a cold place, choose one with an “N” or “North” label. For hot-weather batteries, choose one that has an “S” or “South” label.

Get A Maintenance-Free Battery

Maintenance-free batteries reduce the need for constantly checking your fluids. That alone is reason enough for you to pick maintenance-free batteries over conventional ones. The price difference will be worth it.
