Battery Torque Wrench: A Beginner’s Guide
New to using a torque wrench? Our comprehensive beginner’s guide covers everything you need to know to operate a battery torque wrench, from step-by-step instructions to learn how to use a torque wrench properly to choosing the right wrench in the first place.
What is a Torque Wrench and Why Do You Need One?
A torque wrench is a specialized tool that applies a specific amount of torque to a nut or bolt. Torque wrenches come in various types, including click torque wrenches, beam torque wrenches, and electronic torque wrenches.
Getting the torque right is all-important in many applications, as over-tightening or under-tightening can lead to damage, leaks, or even safety hazards. This is where a battery torque wrench can change the game for both professionals and DIY enthusiasts.
How Does a Battery Torque Wrench Work?
A battery torque wrench is a cordless, electronic version of a traditional torque wrench. It uses a battery-powered motor to apply the correct amount of torque to a fastener, and often includes a digital display for easy reading and setting the desired torque value.
When you use a battery torque wrench, you set the desired torque value using the digital display or a dial, depending on the model. As you begin to tighten the nut or bolt, the wrench will monitor the amount of force being applied. Once you’ve reached the correct torque setting, the wrench will either stop automatically or give an audible click to signal that the proper torque has been achieved.
Step-by-Step Guide: Using a Battery Torque Wrench
Step 1: Determine the Required Torque Specification
Before you start, you need to know the correct torque specification for the nut or bolt you’re tightening. The torque value may vary depending on the application, material, and size of the fastener. You can usually find this information in the manufacturer’s manual or our spec sheet.
Step 2: Set the Torque Value on Your Wrench
Once you know the required torque specification, you can set this value on your battery torque wrench. On most digital models, this is as simple as using the buttons or dials to input the desired torque value, usually measured in foot pounds (lb·ft) or Newton meters (N·m).
Step 3: Fit the Appropriate Socket and Attach to the Fastener
Select the correct size socket for your nut or bolt and attach it to the square drive of your battery torque wrench. Make sure the socket is fully engaged and secured before proceeding.
Step 4: Tighten the Fastener Until You Reach the Set Torque Value
With the socket in place, begin tightening the nut or bolt. The battery torque wrench will monitor the force being applied. Continue tightening until you hear the click or the wrench stops automatically, indicating that you’ve reached the correct torque setting.
How Do You Calibrate and Maintain Your Battery Torque Wrench?
Your battery torque wrench must be regularly calibrated and maintained to ensure it continues to provide accurate results. The calibration frequency can differ depending on the manufacturer and usage, but a general rule of thumb is to calibrate your wrench at least once a year or after a specified number of cycles.
ALLTORC offers calibration services for a wide range of torque tools, including torque wrenches, to ensure your equipment always performs at its best.
How Do You Choose the Right Battery Torque Wrench?
Multiple battery torque wrenches are on the market from different brands and with various specifications. The aim is to buy a torque wrench that meets your and your application’s needs. Consider these factors to break down your choices:
- Torque range – Make sure the wrench covers the torque values required for your applications.
- Accuracy – Look for a wrench with high accuracy, typically ±5% or better.
- Durability – Choose a wrench built to withstand the demands of your work environment, with features like impact-resistant housing and IP ratings for dust and water resistance.
- Ergonomics – A comfortable, well-balanced design can make a big difference during extended use.

What Are the Advantages of Battery Torque Wrenches?
Based on the functionalities of battery torque wrenches we’ve covered so far, these are the advantages you can expect over traditional wrenches:
- Their cordless state means no more air hoses and power cords. This makes battery torque wrenches ideal for tight spaces, remote locations, and applications where tripping hazards are a concern.
- Their digital displays and electronic controls allow you to use a torque wrench effortlessly. By easily setting torque values and getting clear readings, you ensure accuracy and repeatability in your work.
- Battery torque wrenches operate with significantly lower vibration and noise levels, creating a safer and more pleasant working environment.
- Modern battery technology keeps these wrenches surprisingly light. This reduces fatigue and improves maneuverability, especially during extended use.
- Many advanced models offer data logging capabilities. This way, you can track torque readings, ensuring proper fastening and compliance with job specifications.
