What Is A Car Battery?

Before we dive into today’s article, let’s have a quick recap for those that need it! A car battery is a rechargeable battery used to start your car.

Essentially, the battery provides an electric current to your starting motor. The starting motor will start the internal combustion engine that gets your car moving. 

Without a working and charged battery, your car will not start, making it an important part of your car.

There are a few different types of batteries out there for cars, RVs, trucks, and other vehicles including lead-acid batteries, 12V batteries, gel, and lithium batteries.

You can find out what type of battery your vehicle has by checking your manual or asking a mechanic to take a look under the hood for you. 

The lifespan of a car battery varies slightly depending on the type of battery you have and how much strain you put the battery under (if you frequently drain it, or use your car daily).

You might need to replace your battery throughout your car’s lifespan, with the price varying depending on the type of battery you choose.

Be sure to speak to a mechanic and have a professional change and regularly service your battery to ensure your car is running safely at all times. 

Now that we have briefly established what a car battery is, let’s move on and take a look at how much they weigh!

How Can I Check The Weight Of My Car Battery? 

The easiest way to work out your car battery is to weigh it. You can use a home weighing scale to do this if you want, but make sure you do this outside.

The last thing you want is lead or corrosive materials leaking on your kitchen floor! 

If you aren’t able to remove your car battery yourself, the weight should be printed on the side for you to check.

Your battery will have been weighed in the factory and had that weight stamped on it, so you can use this as a quick guide. It saves you plenty of time and means you aren’t spilling any solution anywhere! 

It is worth noting that the weight of your battery will vary slightly as a wet cell battery uses up water in the solution, making it slightly lighter than before the battery was turned on.

Although the weight will fluctuate, this won’t be by a lot, so you can take the weight printed on your battery as pretty accurate. 

Final Thoughts 

And there you have it! Car batteries usually weigh 40lbs, although there are batteries far lighter and heavier than this on the market.

Most commonly, a car battery will fall within the 35lbs to 45lbs range, but you can find batteries that weigh as little as 27lbs and as heavy as 53lbs! 

To find out how much your car battery weighs you can either check the weight printed on the battery or weigh the battery yourself, just be sure to take care to avoid spilling any corrosive liquids!
