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.
