Battery life and compatibility
When choosing a battery-operated tire impact wrench, it is important to consider battery life and compatibility. You want a tool that will last through your projects without constantly needing to be recharged. Additionally, having batteries that are compatible with other tools in your collection can be cost-effective and convenient.
Most battery-operated impact wrenches use lithium-ion batteries, which offer long-lasting power and consistent performance. When shopping, look for tools with long-lasting batteries and consider the benefits of buying from brands that offer interchangeable batteries across their cordless tool lines. This will give you more flexibility and potentially save you money in the long run.
Battery voltage is another important consideration. While higher voltage typically means more power, it also affects the weight and size of the tool. For smaller jobs or work in tight spaces, a 12-volt impact wrench may be a better option due to its compact size. For most automotive tasks, an 18-volt or 20-volt impact wrench will provide more than enough power.
In addition to voltage, pay attention to amp hours (Ah), which indicate the battery's capacity. Think of amp hours like the volume of a gas tank – the bigger the number, the more gas (or in this case, power) you'll get. A higher amp-hour rating means the battery will last longer between charges, so look for batteries with higher Ah ratings if you want to work for extended periods without needing to recharge.
When it comes to battery compatibility, some brands worth considering include DEWALT, Milwaukee, and Makita. These brands offer a wide range of cordless tools that use interchangeable batteries, making them a good choice if you already own other power tools from the same brand or plan to expand your collection in the future.
By considering battery life and compatibility, you can ensure that your battery-operated tire impact wrench will not only perform well but also be a convenient and cost-effective addition to your tool collection.

Variable speed settings
Most impact wrenches have three or four speed settings, allowing you to reduce the revolutions per minute (RPM) and torque to lower levels and avoid mishaps. More advanced models have modes that automatically slow the wrench after it has broken off a bolt to prevent spinning it off. Some even have controls that let you dial in lower torques to simulate hand-tightening or wrench-tightening.
For example, the Milwaukee M18 Fuel 1/2-Inch Impact Wrench, considered the best overall by Popular Mechanics, has four modes, three different speeds, and a bolt removal mode. This allows for easy speed and torque adjustment for the task at hand. The bolt removal mode is especially handy as it slows down the speed and torque once a nut or bolt is loosened, preventing it from running off.
