How Long Does Cordless Drill Battery Last?

Here is a quick answer to your question:

Nowadays, Lithium-ion (Li-ion) batteries are mostly used in electronic gadgets and cordless tools. Normally the life of these batteries is from 3-5 years.

These batteries offer you excellent 1500+ charging cycles and lower self-discharging discharging. The Li-ion batteries are capable of providing 3.0 Ah to power up medium to high powered devices.

You might also be interested in finding out for how many hours cordless drill batteries last. The answer to this question is not straightforward. This ‘time’ thing varies from one cordless drill to another.

There are some cordless drills that offer merely two hours of backup once fully charged. However, there are some best cordless drills that last 4, 6, 8, and even 12 hours before requiring a recharge. 

For home users, we generally recommend you to purchase one offering you 4-6 hours of battery backup time but if you’re a professional then you should go for a cordless drill that offers you a massive 8-12 hours backup.

Another important thing that you must consider is that a 4-hour backup doesn’t mean exactly 4 hours.

Some people get below 4 hours backup while others keep on working for 5 hours while using the same drill it does totally depends on the style of use & how much hard operation you perform with it.

Factors Affecting Cordless Drill Battery Performance

Factors Affecting Cordless Drill Battery Performance

Before using your cordless drill in power-eco mode, it’s essential to go through different factors that lead to quick battery consumption and prevent them.

There are quite a number of factors to look at and we’re sure that these will help you in understanding how long cordless drill batteries last. Once you’ve gone through these dynamics, you’re good to go further.

So, let’s just begin:

1. Battery Specifications

Different cordless tools come with a variety of battery specifications which play an important role during usage.

As a beginner, these specifications tend to be confusing but actually, these are not at all.

Just try to remember how many times you’ve seen the following things on cordless tools & apply them before buying. Let’s go through these things one by one:

Voltage (V)

The battery voltage (V) of any cordless tool determines its power. So, a cordless drill with a higher voltage value is more powerful.

For instance, a cordless drill operating at 240 V is more powerful as compared to the one operating at 120 V. However, a single drill is not suitable for every task so you should be careful with your choice.

Keep remembering, power comes with a cost and that is, quick battery consumption. If you’re looking to do light work like drilling soft cardboard then using a high-powered drill is not a wise option at all.

Because a powerful cordless drill will consume the battery quickly. Similarly, drilling a wall requires to try to use a high power drill.

Opting for a low-powered drill will simply not do well except running out of power and end up wasting your energy, time, and effort.

Ampere-hour (Ah) of battery

People commonly ask this question: What does Ampere-hour (Ah) actually mean? In simple words, the total current per charge that your cordless drill battery can supply in one hour is defined by the quantity Ampere-hour (Ah).

It’s the basic rule of electronics: more power requires more current. Hence, for drilling tasks that don’t require too much power, you should try to use a cordless drill delivering less current in one hour.

For example, under ideal conditions, a 2.0Ah battery will provide you 2.0 amps current and completely discharge in one hour. Considering this logic, you can expect 4 hours backup time with continuous 2.0 amps charge from 8.0Ah battery. 

Within ideal conditions, this 8.0Ah battery might be able to run for more than 4 hours.

For example, 8.0 Ah can provide you 8 hours battery backup if it delivers 1.0 amps current. Similarly, if the same battery provides 0.5 amps of current then you can get a gigantic backup of 16 hours or more.

In both examples, you can decide drill according to the task you mostly do. 


People normally don’t consider this factor but tell you honestly this is really important in answering the question of how long cordless drill batteries last.

To put it simply, let’s look at it this way: the battery of the cordless drill starts losing its charge if you don’t use it after charging it. Some batteries discharge at a lower rate while other discharge at a faster rate.

For instance, a battery with 4% self-discharging will lose 4% of its total charge in a single month which is theoretically, 1% per week. So, if you use the drill immediately after fully charging it, then you might get extended battery life.

However, in case of using it after you’ve charged it 1-2 weeks ago then be sure that your cordless drill battery isn’t going to last that much. Self-discharging is measured in change percentage per month.

Type Of Battery

Different electronic tools are equipped with different types of batteries and each type has certain characteristics and applications. You might be wondering why we’re going to discuss different sorts of batteries. Because this will help you in understanding how long does cordless drill battery lasts

Some common types of batteries are:

1. NiCD (Nickle Cadmium battery) – Nickel Cadmium (NiCD) batteries have been around since the 1940s. NiCD batteries are cost-effective, robust, and offer great charging life (1000+ charges). Hence, these batteries are not eco-friendly and the long run.

2. NiMH (Nickle Metal Hydrid) – Apart from being economical, these batteries are best suited for medium-powered appliances (2.2Ah to 3.0Ah).

3. Lead-acid – Lead-acid batteries are absolutely safe to use and offer an excellent battery life cycle of about 1200 charges. However, the self-discharging is up to 20% which is on the higher side for medium to high powered cordless drills.

4. Li-ion (Lithium-ion) – Li-ion batteries are probably the most power-efficient, cost-effective, and offer great capacity.

These batteries can hold an immense amount of energy and suitable for multiple sorts of devices ranging from smartwatches to professional drill machines.

The Li-ion batteries have battery cycles up to 2000 which is a great thing. Apart from this, you get a lower self-discharging rate which is 8%. At the same time, these batteries are light-weight and small.

This feature offers excellent portability. Despite the self-discharging rate is greater when compared with NiMH batteries yet Li-ion batteries offer 3.0+ Ah which is great for high-powered devices.

Because every cordless drill comprises of Lithium-ion battery so I decided to pick some best interchangeable lithium-ion batteries;

Note: Pick the lithium-ion battery according to your drill model. It is possible that the battery with other models might not suit your cordless drill.

2. Environment Matters A Lot

You might feel it astonishing that the environment also plays an important role in protecting or damaging the battery of cordless drills. 

Too moist environment and overheating can damage battery storage capacity a great deal.

To determine how long cordless drill batteries last, you’ll need to carefully look at this. So, it’s always beneficial to consider your working environment as well as the storage section of your cordless drill.

3. Mishandling The Cordless Drill

A cordless drill is an extremely handy tool for everyday jobs at home or office. Most of us have toolboxes and shelves at our homes that are allocated for storing tools.

Some of us use tend to throw the cordless drill in the storage compartment after completion of the job without even set it in its handle case. It is a serious issue and it can cause serious damage to the drill as well as the drill battery.

It results in either drill malfunction, reduced battery backup, or a decrease in performance. 

4. Overcharging

Many times, we plug our device for charging and accidentally forget about it. It’s true that batteries do take time for charging.

However, if your device is still plugged in despite being fully charged then it results in overcharging. As a result, this mismanagement damages the battery’s ability to store charge and this ultimately results in reducing the battery backup of a cordless drill.

5. Discharge Battery Completely Before The Next Charging Cycle – A Common Myth

It’s a pretty common misconception that draining the battery completely before charging and it is good for battery life. However, a lot of us commonly practice this myth especially with our mobile phones and laptops.

So, it’s always a good idea to consider this factor if you’re looking to find out how long cordless drill batteries last.

6. Drilling Technique

Any drilling job expects does not only expect a suitable drill but also the right technique from its users. Using the right technique saves your effort and increases the life-span of your drill.
