The Best Car Batteries For 2023

Most car owners don’t plan on buying a new car battery until it’s too late.

The thing with car batteries is that it’s only being used for a couple of minutes a day. Once your engine is running, the battery is recharged by the alternator. Even if a car battery is already past its recommended lifespan, everything still seems perfectly fine to most people.

However, the older a battery is, the less reliable it gets. If you don’t plan on regularly replacing your car battery every 3 to 5 years, you’re likely to need a jump start or be stuck in the middle of nowhere when you least expect it.

How To Choose The Right Car Battery

The first thing you should check when replacing your old car battery is the Battery Group Size specified by the manufacturer. Battery Group Size standards are determined by the Battery Council International or BCI.

If the battery you’re looking at has the same BCI Group Size number recommended by your car’s manufacturer, it should fit right in the factory battery location.

A battery that’s too small will move around and has a higher chance of getting disconnected from the battery terminals while you’re driving. Getting a battery that’s too large will make it difficult to close your hood. In many cases, it may even dent your hood when you slam it closed.

If you feel that you need a more powerful battery, don’t just pick a battery with a higher Group Size. A higher Battery Group Size number doesn’t necessarily mean the battery casing is larger or that it’s more powerful.

You should first check the physical dimensions of the battery. If its measurements are close to your old battery’s Group Size, you should be able to make it fit.

The next thing to consider is the battery’s advertised cranking amps. If you pick a battery that has lower cranking amps, then you might have trouble starting your vehicle. Some manufacturers may only advertise a battery’s Cold Cranking Amps which should be enough to determine if your new battery is a good match.

You also shouldn’t just choose a car battery with the highest Cold Cranking Amp rating. This number only really matters if you’re living in an area with really cold winters and if you are already having issues starting your vehicle.

You should also check the battery’s reserve capacity and rated capacity. If you choose a battery with a lower amp hour rating, you may experience issues with your electrical system. A common symptom of a weak battery is dimming headlights, which makes it harder to see where you’re going at night.

How to Remove and Install a Car Battery

Removing and installing a car battery is very simple and requires minimal tools, as long as you have a battery that fits properly. All you need is a 10mm wrench or socket.

The most important thing to remember is to remove the red negative battery cable first. The negative wire connects to your car’s body via a ground cable. If you try to remove the black positive battery cable with the negative terminal still connected, your metal wrench may accidentally touch the car’s body and cause a short circuit. After removing the battery cables simply unscrew that nuts that hold down the battery.

When installing the new battery, connect black positive battery cable first. After installing both cables, make sure to properly tighten the screws of the battery holder so it doesn’t move around while you’re driving.

How to Check if You Have a Bad Car Battery

You can’t just test a battery by using a multimeter. A bad battery can still show a 12 volt reading with the engine off because it’s constantly being recharged by the alternator while you’re driving.

The best thing to do is to take it to your local mechanic or auto parts store so they can do a load test with more sophisticated equipment.

You’ll know when to replace a car battery if you’re cranking the engine for much longer than usual, or if you’re always needing a jump start. You can also test if the battery is not able to handle your car’s electrical load by turning on your lights, HVAC, wipers and radio all at once. If the battery is not strong enough, you’ll notice that the headlights are dimmer than usual or that some electronic accessories not working at their best.

Final Words

If you want to get the most out of your money, choose a battery with a good warranty. Some manufacturers only offer a limited warranty and may not honor it if the battery is too old, even if you just recently bought it.

If you want to take better care of your new battery and prolong its life, make sure it’s regularly charged either by driving longer distances from time to time or connecting it to a smart trickle charger.

Batteries degrade much faster if they are fully discharged for long periods of time. If you’re only taking short trips every so often, or if you’re living in an area with extremely cold or hot temperatures, your battery’s lifespan can decrease dramatically.

Don’t let price or brand determine the quality of the battery. Always check the specs before buying your next battery and make sure it’s a good fit for your needs.
