How Long Does It Take To Charge A Cordless Drill?

Drills and drivers are widely used in construction, which is an essential task. A couple of decades ago, there were many corded power tools, but with the development of battery technology, cordless drills and drivers have become more popular.

Without a battery to power up your cordless drill, it’s pretty much useless. If you happen to completely run down your drill battery and don’t have an extra or you’re concerned about leaving your battery in the charger, you may be wondering how long does it take to charge a cordless drill?

On average, a cordless drill battery can take up to 15 minutes to 5 hours to fully charge. If the charger is labeled as a fast charger, the battery will take less time to charge up.

Although the time it takes to charge a cordless drill depends on the battery capacity, charging conditions, and charging technology. 

In today’s article we will share with you the charging times of different brands of cordless drills and factors that can affect this charging time.

Charging Time

Lithium-Ion Batteries 

Cordless drill batteries have improved over the years, and most popular brands now use Li-Ion (lithium-ion) batteries. These batteries deliver more power, have higher capacity, and longer run times.

As a result, a Li ion battery takes less time to charge than other batteries. Typically, lithium-ion batteries charge between 30 minutes to 3 hours.

Makita Cordless Drill 

Makita uses some of the most advanced technologies that make its lithium-ion batteries charge faster than standard lithium-ion batteries.

It puts itself ahead of its competitors by using smart systems and features that draw charge quickly and efficiently.

Makita offers its batteries in the range of 1.5 Ah, 2.0 Ah, 3.0 Ah, 4.0 Ah, 5.0 Ah, and 6.0 Ah. The Makita 18V 1.5 Ah rechargeable battery takes about 15 minutes to charge, while the 2.0 Ah takes only 20 minutes. 

Not only does Makita have an industry-leading charge time, but it also delivers longer runtime than other Li-Ion batteries with similar capacities.

This means that you’ll spend more time using your cordless drill and less time charging its battery.

Besides fast charging technology and longer runtime, Makita also has microprocessors, monitoring tools, and advanced systems that protect your battery from overheating, overloading, or over-discharging.

Makita batteries and their charge times:

Battery CapacityCharging Time
6.0 Ah60 min
5.0 Ah50 min
4.0 Ah40 min
3.0 Ah30 min
2.0 Ah20 min
1.5 Ah15 min

Ryobi Cordless Drill 

The charge time for a Ryobi battery mainly depends on the type of charger. If you’re using an 18V ONE+ lithium-ion battery, you can charge it with any Ryobi ONE+ charger.

The charge time will vary from charger to charger, depending on the charge rate and the battery power.

A Ryobi 18V ONE+ Fast charger can charge at a rate of 5.0 Amp/h, meaning it would take just 1 hour to charge an 18V 5.0 Ah battery. With a 4.0 Ah battery, it would take about 50 minutes to charge up.

Ryobi chargers and their charge times:

Type of ChargerCharge Rate
18V ONE+ Compact Charger1.5 Amp/h
18V ONE+ Fast charger5.0 Amp/h
18V ONE+ In-Car Charger1.5 Amp/h
18V ONE+ Compact Charger 22.0 Amp/h
18V ONE+ 6-Port Charger2.7 Amp/h

Note that these charge times are only referenced from Ryobi and may be different in a real test scenario. You may also check your service manual for specific charge times.

Dewalt Cordless Drill

Dewalt batteries are mainly available in 20, 60, and 120 volts. Since they are higher capacity batteries, you can expect them to sit on the charger for longer.

Different Dewalt chargers have varying charge rates and some can take up to 3 hours or more to fully charge a dewalt battery.

Also, with a Dewalt 40V Max Battery Charger (DCB114), you can charge the 4.0 Ah 40-Volt max Li-Ion battery in about 90 minutes, and the 6.0 Ah 40-Volt max li-ion battery in about 130 minutes.

Another popular Dewalt product, the Dewalt (DCB107) 12V/20V Max Charger has a 1.25 Amp/h, so you can expect it to charge a 20V, 4 Ah Li-Ion battery in about 3 hours.

If you own the Dewalt 12/20V MAX Charging Station, it will charge your 4 Ah battery in about 90 minutes, and a 3 Ah battery in 60 minutes.

Since Dewalt doesn’t clearly state exactly how long it takes to charge their batteries, you may have to check the service or instruction manual that comes with your product.

Milwaukee Cordless Drill 

Milwaukee is one of the world-leading companies when it comes to cordless tools and batteries. Its M12 and M18 Li-Ion batteries (12V and 18V) are known to deliver some of the best runtime, power, and speed in the industry.

The standard Milwaukee M18 & M12 charger can charge a 12V or 18V battery in 40 to 60 minutes, depending on the battery’s capacity.

A better upgrade is the Milwaukee M18 & M12 Rapid Charger. The Rapid charger can charge up to 40% faster.

The recently-released Milwaukee Super Charger charges even faster. Milwaukee claims that it charges the M12 and M18 batteries up to 4x faster.

As a result, it can charge an 18V, 12.0 Ah battery in just 1 hour, while the standard Milwaukee charger will take about 240 minutes to charge it to full capacity.

Black and Decker Cordless Drill

Black + Decker cordless drills are available in 12V MAX*, 18V, and 20V MAX* configurations.

Most Black + Decker cordless tool batteries take between 30 minutes to 3 hours to charge to full capacity. Some batteries can take up to 3 to 6 hours to charge up when completely drained.

If you’re charging your battery for the first time, or after prolonged use, it may take up to 9 hours. We suggest consulting your service manual for more information.

Bosch Cordless Drill Driver

Bosch cordless drill batteries consist of several voltages such as 12V, 18V, Procore 18V, and 36V.

Bosch 12V battery will take 25min – 240min. 18V batteries will take 12min – 200min, and 36V batteries require 30 min – 55min to charge fully. Using a high amperage charger will reduce the charging time.

Craftsman Cordless Drill 

Craftsman drill batteries will take 30 min – 2 hours for charging 0% to 100%. Most of the Craftsman drill batteries are fully charged within 1 hour.

Charging speed is highly dependent on the charger. More ampere chargers can speed up the charging process.

Factors that affects charging time

Environmental Conditions

For the long lasting batteries, charging should take place at room temperature, which is approximately 18°C- 21°C. Charging batteries in the cold can damage the cells, this is especially true when charging in the winter.

Battery Conditions

The battery charging cycle is limited. Li-Ion batteries can be charged up to 1000x times under optimum conditions. So when you charge, it will be reduced from the total.

Therefore, to extend battery life, do not recharge the battery for a lot of times when not needed or unnecessary, rather always continue to use it for so long until it is almost empty or at 10% to 20% charging status.

Charging Technology

Batteries can be charged with many technologies. Charging speed is different according to the type technology.

Currently, most brands offer fast chargers and rapid chargers and using this kind of equipment, batteries will charge faster.

Frequently Asked Questions

How do you know when a cordless drill is fully charged?

One thing you should do to know when a cordless drill is fully charged is by checking the voltage indicator on the multimeter.

A fully charged battery should test at least 1 volt higher than the voltage that is listed on the battery. For example, an 18-volt battery should test at 19 volts or higher.

Can you overcharge a cordless drill battery?

Yes, a cordless drill can get overcharged. Overcharging can damage a battery and shorten its life, and not all chargers shut off automatically.

Heat is deadly to rechargeable batteries and can even cause them to explode. If the battery gets hot to the touch, let it cool down before recharging or using.


Charge rate and charge times vary from product to product. Makita batteries charge faster than other batteries in the cordless tool industry because of the advanced technologies they use.

If your drill battery is taking longer than normal to charge, there may be a problem with your battery. Also, I don’t advise leaving your battery in the charger when it’s fully charged as it can reduce its lifespan.
