How Long Will DeWalt Cordless Batteries Last?

The invention of cordless power tools was a game changer for the construction and DIY industries. No longer were workers tethered to a power outlet, limited by the length of their extension cords.

But with this newfound freedom came a new set of challenges, one of which was how to keep cordless tools running for long enough to get the job done.

DeWalt has been at the forefront of this challenge since it introduced its first cordless power tool in 1994. Today, they offer a wide range of cordless tools, each with its own unique battery life.

When charged, a work or homeowner can get a project done without the hassle of being restricted by a cord. However, like any battery, over time, they wear down and need to be replaced.

On average, you still can expect to get a minimum of 3 years out of a DeWalt battery. There are several factors that affect how long a DeWalt battery will last.

How Often It's Used

It doesn't matter if it's a vehicle, lawn mower, or a battery-powered tool; over time, they all will eventually die. The lifespan of a DeWalt battery is no different.

How often you use your cordless power tools will affect how long the batteries last. Obviously, the more you use them, the shorter the lifespan will be.

For example, a general contractor who works 40-60 hours a week will go through batteries much faster than someone who only uses their power tools for around 10 hours a week.

However, if you only use your tools occasionally—maybe once or twice a year—for at-home projects, then your batteries could last much longer.

In addition, the power output you use will also affect the lifespan of your battery. If your DeWalt battery is constantly used at max power, the battery will wear out more quickly.

Type Of Battery

The quality of the battery will also affect how long it lasts. For example, DeWalt FLEXVOLT 20V/60V Max 15.0Ah Battery is one of the best on the market and will last much longer than the average battery.

On the other hand, a battery that is of lower quality will have a shorter lifespan. This is something to consider when purchasing a power tool since, in many cases, you get what you pay for.

In other words, you get what you pay for. With that said, DeWalt does offer a wide range of batteries to fit any budget.

How You Care for the Battery

Like any battery-powered device, how you take care of your cordless power tools and their batteries will affect their lifespan. Let's take a look at key battery maintenance tips to help extend the life of your DeWalt batteries.

Charge Before Complete Battery Loss

It may seem obvious not to charge a DeWalt battery until it is completely dead. However, this is actually bad for the battery.

Instead, when you have significant power loss, you should remove the battery and charge it. Running the battery completely dead adds extra stress and can shorten the lifespan.

Let The Battery Come To Room Temperature

Once your DeWalt battery has reached full charge, it's best to let it come down to room temperature before using it.

If you put a battery that is too hot or too cold into a DeWalt power tool, it can damage the battery and affect its performance.

Charge The Battery Completely Before Use

This is another battery charging tip that will help extend the lifespan of your DeWalt batteries.

It's best to charge the battery all the way before using it. This will help ensure optimal performance and also prevent you from running into any issues with a power tool that uses a lot of battery power.

Store In A Cool, Dry Place

This is a tip for when you're not using your DeWalt cordless power tools.

When you're done working for the day, it's best to store your tools and batteries in a cool, dry place. This will help prevent any damage that could be caused by extreme temperatures or moisture.

This also includes charging a DeWalt battery. Avoid charging it in direct sunlight or in an area where the temperature could rise to an extreme level, such as a car parked in the sun.

DeWalt states that temperatures above 105° F (40.5°C) and below 40°F (4.4°C) can damage the battery.

Keep The Battery Contacts Clean

Like any battery-powered device, it's important to keep the contacts clean. This will help ensure a good connection and also prevent any issues with the battery or power tool.

You can use a cloth or an old toothbrush to clean the contacts. Just make sure they're completely dry before you put the battery back in the power tool. If the terminals are showing corrosion, then use baking soda and water to clean them.

When done, ensure the terminals are completely dry before reinserting the battery.

What Should You Do With Old DeWalt Batteries?

Once your DeWalt battery has reached the end of its lifespan, you may be wondering what to do with it.

The best option is to recycle the battery. This will help prevent any damage to the environment and also ensure that the materials are properly disposed of.

DeWalt offers a recycling program for its batteries and power tools. You can find more information at DeWalt service centers.

How Long Will A DeWalt Battery Last On A Full Charge?

Like the lifespan of a DeWalt battery, the number of hours it will last on a full charge will depend on the model and type of battery.

Typically, you can expect to get 30 minutes to 4 hours on a full charge. The power output of the battery will also affect how long it will last on a full charge.

For example, if you are constantly running your battery at max power, it will not last as long as if you are using it at a lower power setting.

So, if you don't need the battery's full power, it's best to use a lower setting. This will help you save battery life and extend the battery's lifespan.

How Long Does It Take To Fully Charge A DeWalt Battery?

Depending on what charger you're using, it can take anywhere from 1-3 hours for a complete charge. However, DeWalt recommends charging your battery overnight for 8 hours at room temperature.

This allows the battery to go through a full charging cycle. This is also healthy for the battery and helps to prevent any issues, such as memory effects.

For those who need their batteries throughout the day, DeWalt recommends having 2 batteries. In addition, getting a fast charger can help reduce the amount of time it takes to charge your battery.

How Do You Know When It's Time To Replace A DeWalt Battery?

There are telltale signs that your DeWalt battery is on its last leg. If you notice any of these, then it's time to replace the battery.

Won't Hold A Charge

If you charged your DeWalt battery overnight to find that it's still not working, then it's time to replace the battery.

This could be caused by a number of things, such as age or overuse. However, if you're noticing that your battery isn't holding a charge like it used to, then it's time for a new one.

Loses Charge Quicker Than Normal

If it seems like your battery is draining faster than it used to, then this is another sign that it's time for a replacement.

Physical Damage

If you notice any physical damage, such as cracks or leaks, then this is a sign that your battery needs to be replaced.

Indicator Lights

Like a car's dashboard, DeWalt batteries have indicator lights that tell you when it's time for a replacement. This can include:

  • Rapid flashing of red light
  • Red with yellow light
  • No light at all

If you notice any of these indications, then first check the charger. If the charger is working properly, then it's time for a new battery.
