How to Know What a Car Battery Weigh

The easiest way to know the weight of a car battery is to check the packaging or the label, as it’s usually written there. So, looking closely at the label will give you a quick response to the battery’s weight and let you know what to expect.

But some batteries don’t have their weight written on them, so you’ll have to find their weight through further information. Usually, it is a battery’s content that determines its weight and not its body. So, the weight of a lead-acid battery can be reduced significantly if its fluid is exhausted.

So, in such a situation where the fluid is depleted, a lead-acid battery that weighs 40 pounds can be reduced to 15 pounds. Therefore, look out for the content of a battery to ensure that it’s lightweight doesn’t mean it’s empty.

Some of the factors contributing to the weight of a car battery include the battery’s size and type.

The Size

The battery size is an essential factor that determines its weight. Size is also what affects an electric car battery’s weight. A battery that has more constituents will be bigger and therefore, weigh more than the smaller one.

Bigger batteries are usually used for cars that need extra power to function well because they have bigger engines. If you have such a car, your battery will be bigger and heavier as it’ll weigh more than 40 pounds.

Types of Battery Weight

There are different types of battery weights, and knowing them will help you determine the correct weight of a car battery. They include:

  • Lightweight Batteries: lightweight batteries are great when the target is to save energy and still get high performance. They weigh around 10 to 20 pounds, making them the best for small cars. However, these battery types can be too light for some cars.
  • Standard Batteries: standard batteries will weigh around 40 to 60 pounds. It is excellent for most cars, but your car model determines the actual battery size you’ll need because some vehicles will require the ones that weigh 40 pounds while others require the one that weighs more.
  • Empty Batteries: empty batteries have no content. There is nothing inside them as they don’t contain the components of lead-acid or lithium-ion.

 When heavy or standard battery models are empty, they weigh about 15 pounds, while empty lightweight battery types weigh about 7 pounds.

It is clear that battery types will affect the battery’s weight. Amaron car battery weight is about 19.84 pounds making it light and a good choice for those that want such lightweight batteries.

However, remember that lightweight batteries are not the best if your car requires more power to function well. Always take some time to know the battery weight your car needs for maximum function before choosing one.

Yes, car batteries usually have scrap value, but this value depends mainly on the battery’s lead content and the battery type. The average value varies, but it is estimated at 0.21 to 0.41 cents for a pound.

That means the scrap value of a 30 to 50 pounds battery will be between $6-$20. However, it is best to contact a local scrap yard as they’ll be in the best position to determine your battery’s scrap value.

Why does a car battery go flat if it is not used often?

A car battery goes flat if not used for some time because it discharges naturally due to the chemical reaction that goes on in the battery.
