Best Voltage For Cordless Tools

The power of your cordless tools largely depends on the voltage. For power tools, voltage ranges from around 3 to 48 volts. The higher the voltage, the more powerful the tool will be, and generally, the more expensive. A battery’s voltage tells you how much power the cell generates in ideal conditions. It indicates the maximum energy potential of a battery and serves as a necessity to produce an electric current.

Battery Voltage in Cordless Tools

Some cordless tools require more power than others. Tasks that use more torque need batteries with a higher voltage to complete the toughest jobs. For this reason, large cordless shears may require 20V batteries while measuring instruments may only require 12V cells for adequate performance. Battery voltage in cordless tools makes sense this way: the simpler the operation, the smaller the necessary energy supply. That’s why many craftsmen choose to use the 20V MAX instead of the 12V battery for the toughest jobs: higher voltage generates more torque.

Li-Ion batteries, like those used in the Bosch cordless combo kits, are preferred in top-rated cordless tools because of their efficient energy discharge and their high storage capacity. They don’t require the same maintenance as other batteries, and they can be recharged even after short periods of usage without damaging the cell’s performance.

Consider the following when selecting your tool to ensure you choose a voltage that’s right for you:

Light Duty Jobs

Drilling small holes or driving screws into materials such as soft and hardwood, plasterboard/drywall, and plastic is considered light duty and will not require too much power.

For light duty work, consider a cordless drill driver with a lower voltage: 12v or less.

Heavy Duty Jobs

Driving screws and drilling into materials such as soft and hardwood, plastic, and plasterboard as well as metal and ceramic, is considered heavy duty and will require more power.

For heavy duty work, select a cordless drill driver with a higher voltage: 14v or more

How important is the tool’s weight?

Naturally, higher voltage tools weigh more than lower voltage ones. If you are only going to use the tool occasionally, then its weight may not be an issue. Nevertheless, if you’re planning on working for long periods of time, a heavy tool can put excess strain on your arm and wrist.

You should also consider the kind of work you are going to be doing with the tool. Screwdriving or drilling in awkward spaces such as in the rafters of a roof, where the tool will most likely be held above your head, will also become extremely tiring if working with a heavy tool.

Conclusion:

A higher voltage tool will generally be more powerful and will allow you to work with tougher materials and larger screws. Tools of the same brand and voltage are usually able to share batteries. So, for example, if you already have a 14.4v cordless Bosch impact driver and you want to purchase a drill driver, choosing a 14.4v model by Bosch will mean you’ll have more batteries to share between the tools. The voltage of a cordless drill driver will usually be printed on the side of the tool’s battery. Cordless drill drivers range from 10v to 24v. However, naturally, it will also be larger, heavier and more expensive than a lower voltage cordless power tool.

No matter which type of batteries you work with, voltage differences in cordless tools play a major role in overall performance. Higher voltages work in conjunction with more powerful motors to produce greater torque.
