How Long Can You Run A Winch?

More often than not, operating a winch may appear simple. But towing service companies, among other car experts, know the complexity involved in running a winch.

A certain level of knowledge is often required when running a winch. First, you have to know that the condition of your car battery greatly affects the winching process.

The greater the capacity of your battery, the more effective the winching process.

Simply put, if you winch out a car using another car, the rescue vehicle will automatically have high battery needs.

And these requirements get catered for by the stuck vehicle. So, the optimal time you can run a winch greatly relies on the battery capacity.

But car experts can always strike a balance between attaining effective winching and protecting the car battery’s lifespan.

So, which battery should you use to run a winch?

In most instances, car experts always recommend running a winch with batteries containing high capacities. But of course, it depends on your needs.

Check the battery that will work best when winching your car. A small battery without minimal capacity would only make the winching process less effective.

Typically, a winch works using energy from the battery. Therefore, when you can know how long your battery can last, you can determine how long the winch will run.

When calculating how long the winch can run, always put the below factors into consideration:

  • The time
  • The reserve capacity
  • Then use the mathematical formula to identify the pull time.
  • Time Duration of Pull = (A/W) x T
  • A means the reserve capacity of the battery in amperage (this is mostly a constant figure that is 25 amperes)

W stands for the amount of energy the winch uses from the battery. Unlike the reserve capacity of the battery, this is not usually a constant figure.

It varies depending on the type of winch. For instance, a smaller winch is likely to draw less energy. You can identify this figure from the winch instruction manual or your manufacturer.

T stands for the Reserve capacity time of the battery (this is usually in minutes)

Using this formula, you can find out the duration of the pull. Nonetheless, note that most car winches are specially designed to run for an average of ten minutes.

Also, during the winching process, ensure that your battery is running optimally.

However, if your battery is small and has low capacity, it may not be able to get to ten minutes.

Also, note that operating the winch for more than ten minutes is not advisable.

How do you calculate a winch line pull?

Typically, a winch line pull is the power of the winch. This is usually the total load a winch can withstand.

Currently, there are many types of winches. Each varies in configuration and size. Normally, smaller winches are only able to accommodate smaller weights. Similarly, large winches can shoulder heavyweights.

Calculating the winch line pull entails identifying the gross weight of the car and multiplying it by 1.5. Below is the summary of the mathematical formula.

Minimum rated line pull = Gross Vehicle weight x 1.5

You can always find out the gross weight of your car by checking under the driver’s door.

Alternatively, you can look for this information online. All you have to do is state the model and specifications of your car.

If you really can’t seem to find the GVW, consider asking your car manufacturer.

How do you multiply a winch power?

In this present age and time, a winch is a powerful car recovery equipment. This tech equipment can rescue even the bulkiest of cars.

But you have to operate it correctly for it to work effectively. Fortunately, you can also boost its effectiveness by multiplying it’s pulling capacity.

All you have to do is use the right winch accessories and tools. In fact, you can double or triple the winch pulling power.

Doing this enables you to save a lot of time and effort during the winching process. But how do you do this?

If you want to ease your work, always place the anchor point directly from the stuck vehicle. Winching a car from a straight line is unquestionably easier than winching it at an angle.

Always use a snatch block when winching out your car. This way, you multiply the winch’s pulling capacity by either using a double or triple line.

Even so, when using a double or triple line, ensure the anchor point is in its correct position and can withstand high pressure.

Nonetheless, note that the more the winch works, the more it produces heat. Consequently, this can lead to overheating.

So it is advisable to use a high capacity battery.

Can a winch drain your battery?

ATV winches are well known to drain your battery

ATV winches are well known for draining out car batteries.

But what causes this? If you winch your car using a long continuous pull, it is enough to drain the battery.

And once the battery gets drained, it will no longer be able to operate.

If you’re using the correct winch and battery, there are fewer chances that the winch will drain out your battery.

However, the winch only goes as far as the battery will go. Since a winch draws energy from the battery, it will work based on the battery’s capacity.

So, the less the capacity of the battery, the less effective the winch. Additionally, the winch can’t drain the battery when it’s switched off.

Also, always make sure that your winch rope is tight and secure.

Preventing the winch from draining out the battery before the correct time

Some of the ways you can implement to prevent draining the battery during winching include:

Before you begin winching your car, make sure that your car battery is optimally charged. Using a partially charged battery increases the risk of drainage.

Think about it. If your battery is not fully charged, a winch will not likely drain it out much faster.

Charging your battery completely will enable it to complete winching successfully.

Avoid using the internal charging system of the battery often.

Whenever you’re not using the battery, consider using an external charger to charge it.

Why? If you use the car battery often, its internal charging system is likely to become defective by the day. This is because of frequent usage.

You can purchase a smart charger to power your battery. This way, winching would be easier and more effective.

Fortunately, various smart chargers can get directly connected to your battery system.

Can a battery charger power a winch?

Often, powering an electric winch requires you to use a battery that has 12 volts. So most car batteries will work perfectly fine for you.

Moreover, the battery should incorporate 55 amperes to ensure the winch runs efficiently. Typically, winches draw their energy from the car battery.

This, the larger the car battery capacity, the more effective your winch will be. Battery chargers often come in handy when winching.

They give the battery sufficient energy to use when winching. Winching using a fully charged battery is much more effective than using a partially charged battery.

Besides, you don’t want to tamper with the winching process because of a partially charged battery.

How can you prolong the lifespan of your car battery?

Unquestionably, winches can drain the car battery. However, you can always prevent the winch from draining out the car battery.

One way to do so is by using a dual battery. What this means is that you use two car batteries. Separate one of the car batteries strictly for winching purposes.

Doing this won’t wear out your battery quickly. In fact, you might never need to replace your car battery for years.

So, whenever you need to winch out your car, use the battery designed for winching purposes only. This will be much more convenient for you and your vehicle.

Additionally, dual batteries also come in handy when one of the batteries becomes default. You can always use the other one in case of an emergency.

When one battery gets drained during winching, you can always exchange the winch cables rather than recharging the battery.

Consequently, you consume less time and effort.

In summary

Ultimately, the time you can run a winch significantly depends on the capacity of the battery.

Suppose your battery has a larger capacity; your winch can run for a longer period. On the flip side, if your car battery has a smaller capacity, your winch will run for a short time.

But on average, you should not run your winch for more than ten minutes. Running the winch continuously for long periods drains out the battery much faster.

Fortunately, there are several techniques you can incorporate to prevent the battery from draining out faster.

Consider using a dual battery and using a smaller winch. Nonetheless, it all depends on your needs. It would be best to purchase a winch that caters to all your requirements.
