# Cordless Drill Battery Charge Time – (08 Brands Tested)

When you use a cordless drill, you should have more than one battery. Because the battery is discharged when it is used. So you had better keep a few additional batteries to work until you recharge it. So everything depends on the cordless drill battery charge time. Let’s go to the topic.

How long does it take to charge a cordless drill battery? A cordless drill battery will take 30 mins to 5 hours to fully charge. Using an ultrafast charger will take 11 mins. If you use a fast charger, it will take an average of 1 hour. Charging time depends on charger capacity, battery capacity, and charging technology.

In this research, you can find the drill battery charging time for famous brands such as Black and Deck, Bosch, Craftsman, DeWalt, Makita, Milwaukee, and Ryobi. Each battery and its charging time have been mentioned in detail. Some information is grabbed by researching. So according to your brand, you can find the charging time. So let’s read on.

## How to Find the Charging Time of a Battery?

The battery capacity (Ah) divided by the charger current (A) is the time for the battery to charge fully. According to the environmental conditions, battery condition, and charging technology, the time can be varied. For less time, a charge can use fast or rapid chargers.

The charging time is the most important thing for the battery. The least time charging the battery will save you time. If we consider an ideal battery, we can calculate the battery charging time as below. Due to some environmental and other problems, the battery will not charge properly.

Charging Time (Hr) = Battery Capacity (Amh) / Charging Current (A)

Charging Time (Hr) = Battery Capacity (KWh) / Charging Power (KW)

Find the Charging Hours
Problem – A Drill battery is (20V and 5Ah) charged with 20V and 2.5A current. How much time will it spend for charging from zero to 100%?

Solution – (20V*5Amh)/(20V*2.5A) = 2 Hrs

Charging time can depend on the environmental condition, battery condition, and battery charging technology. So let’s see how these facts affect the charging time.

Using these methods, you can find the time for charging the battery. In real conditions, we do not use a battery until its minimum value (0). So the average time will be less than the exact calculation time period.

Environmental Conditions
For the best last long batteries charging should take place at room temperature (approx. 18°C- 21°C). Charging a cold battery can damage the cells. Especially charging in the winter, allow the battery to first warm up to room temperature.

Battery Condition
The battery charging cycle is limited. The Li-Ion batteries can be charged up to 1000x times under optimum conditions. So when you charge, it will reduce from the total. Therefore do not recharge the battery again at every opportunity, rather always continue to use it for so long until it is almost empty (10% to 20% of charging status).

Charging Technology
Batteries can be charged with many technologies. Charging speed is different according to the technology. Currently, most brands offer Fast chargers and rapid chargers. Using this kind of equipment, batteries can be charged fastly.

Considering the above factors, manufactured companies have found the real charging time periods under the real situation. The brands such as Black and Deck, Bosch, Craftsman, DeWalt, Makita, Milwaukee, and Ryobi have different kinds of batteries with various capacities. In order to have the best result, you should use the recommended battery chargers for the cordless drill batteries.

## What is the Charging time for Black and Decker 20V Cordless Drill?

The average charging time for the Black and Decker 20V Cordless Drill is 40 min to 5 hours. For the longest life and best performance can be obtained if the battery pack is charged when the air temperature is between 65°F and 75°F (18°- 24°C).

Black and Decker 20V cordless drill is widely used for drilling purposes. The maximum initial battery pack voltage is 20V, and it can be varied with the conditions. But nominal voltage is 18V. Many tools are powered with the 20V battery, and it is the most used power system in Black Decker. You can find cordless drills and drivers which are powered using 20V batteries.

## How Long Does it Take to Charge Bosch Cordless Drill Driver Battery?

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 required 30min – 55min to charge fully. Using a high ampere charger will be reduced the charging time.

These values are based on the average charging time. According to the charger ampere, this time can be varied. You can find in detail the charging time for each charger and related batteries as follow.

Hi, I am Tom Mackency. It has been 10 years that I have been working as a professional woodworker since 2013. I am really enjoying my carrier by creating many kinds of projects in my workshop. But mostly I like for home improvement projects. Home improvement and DIY projects are the most interesting things for me. More than that, the coolest things are power tools. Those are very precious and efficient than a decade ago. So I try to introduce so many things about power tools, woodworking, DIY projects, home improvement and many more interesting topics here.
