When us talk around batteries, we get to hear around a many terminologies; voltage, ampere, amp-hours, watt, and also watt-hour. These terminologies can be a bit confusing come a non-tech-savvy person. Despite this, expertise some of this terms is important as they help you do the best an option when looking for the right battery because that your car or any type of other electrical device. So, what room watt-hours and also watts?

Watt simply way the amount of strength consumed through a device. It is the voltage multiplied by the variety of amperes (current/ power flow). On the other hand, watt-hours is another means of calculating or measuring the capacity of a battery. Therefore, to understand how powerful a an equipment is, you look at the watt. In the article below, us answer concerns relating to the variety of watt-hours a automobile battery have the right to hold, use, and handle.

You are watching: How many watts in a car battery

How numerous watt-hours go a automobile battery hold?

To answer this question, we an initial have to obtain an expertise of terms choose amperes and also voltage. Once we talk around amperes, us refer to how much electrical power flows per 2nd (current). If the variety of amperes in a battery goes up, then the present flowing with the machine per 2nd also go up. ~ above the various other hand, volt our voltage is the amount of power an electronic circuit gets. Many batteries have actually a solved voltage. Because that example, friend can gain a 6, 12, 24, or 36 volts battery. Except this, many vehicles or devices constantly require a details voltage amount. For example, for a maker that functions on 12v, friend will require a battery that supplies 12V.

Most times, once you are picking a auto battery, us look at various factors. One of these is the amp and also watt-hours friend need. All this always depends on the battery application and also your geography location. Because that example, once you pick a battery to usage in UPS, girlfriend will have actually to take into consideration the capacity that will be enough to cover an ext than two to 3 times the intended outage. To understand this, you will certainly take her average daily use and divide your vehicle battery's voltage to estimate your forced amp hours.

So, come answer our question above, we currently know the watt-hours are another method to measure up the capacity of the battery in your car. To calculation the watt-hours, us multiply the variety of amperes with the battery voltage.

For example, a 24V battery with a 50Ah will have a 2400Wh (24 x 100).

How numerous watts deserve to a automobile battery handle?

For you come understand and answer this question, that is vital to understand your auto battery's voltage and also amperage amount. The lot of watts your auto battery have the right to handle counts on these two crucial things. To understand the number of watts your automobile battery can handle or holds, here's a an easy formula come follow;

Wattage = Amps x Voltage.


A standard automobile battery is rated at 45 amps every hour. When computed top top a range of 20 hours, it means it can crank out 2.25 amps at an typical of 12V throughout the period. Therefore, the wattage will certainly be 540W. Let's take it a look at at different examples also;

Suppose you have actually a auto battery that has 24V and draws 30 amps. To know the power intake of your vehicle you will certainly take 24 x 30 = 720W.

Suppose you happen to have a 2nd different car model in your garage v two gears or rate settings. The auto engine operation on 12V and draws 20A as soon as switched to a speed setup of two. The power usage for this automobile will be 240W (12 x 20). In instance you move to a speed setting of 4, the car engine still operation on 12V but draws 25A. In this case, the power intake (wattage) will certainly be 300W (12 x 25).

From the computations above, the is vital to understand that this formula functions for any type of car battery. Except this, the has likewise been proven to occupational universally. Because of this anyone with any model or a various brand that a vehicle battery can easily calculate its wattage through a straightforward formula.

How many watts does a auto use?

When looking at how plenty of watts a car battery have the right to handle, it is also good to take into consideration how many watts your car can use or an average automobile is an alleged to use.

Honestly, the number or quantity of watt a car uses depends on the battery kind you are using. Mostly all vehicles have various batter sized and also specifications. Let's take an example of a car that provides Lead-acid batteries. This batteries come in 2V cells. The most usual voltages room 2V, 6V, A2V, and 24V. Through lead-acid batteries, the more amps you pull out, the less power intake you get.

It is good to note that, on typical a auto battery can maintain around 4 come 5 amperes for about ten hours. Ns such a case, the battery is related to a 50amp hour battery or 600-watt hour battery. In today's market, countless batteries room rated in ~ a 10-hour rate or 20 hours. This rates typical the number of amperes a battery have the right to sustain because that 20 or 10 hours prior to the voltage drops come a suggest where it cannot be provided again.

Therefore, the amount of watts a auto uses different upon the car and the solution within the car. As every auto is different, because that you to recognize the watt yours use, the is best to measure your car.


Now you know what watt is and also how wattage computations room done. Except this being one of the an essential factors to take into consideration when searching for a automobile battery, there are additional factors you should likewise keep in mind.

Some of this include:

Selecting the right-sized battery v the appropriate cell power,

A good battery brand the assures girlfriend of gift safe and highly efficient.

I hope the from this information you will be able to make a well-informed decision will selecting the battery the suits your needs.
