Battery and Charger

The Makita DTW190Z 18V impact wrench does not include batteries or a charger. It is part of Makita's 18V LXT line, so it is compatible with all of Makita's 18V Lithium-Ion batteries.

Some of the most popular battery options include:

• BL1830 - 3.0Ah battery
• BL1840 - 4.0Ah battery
• BL1850 - 5.0Ah battery

For longer runtimes on high torque applications, the higher capacity 4.0Ah or 5.0Ah batteries are recommended. The 3.0Ah battery will provide adequate runtime for most general automotive uses.

As for the charger, the ideal choice is the Makita DC18RC rapid optimum charger which can charge an 18V LXT battery in as little as 22 minutes. There is also a dual port DC18SD charger available to charge two batteries simultaneously. Both of these chargers properly optimize the charging process for long battery life. Alternatively, the basic DC18SE single port charger gets the job done at a lower cost.

When purchasing batteries and a charger, it's best to choose from the same 18V LXT series as the impact wrench for proper compatibility and performance. This ensures you get the full potential from the tool.

Noise Level

The Makita DTW190Z operates at a noise level of 84 dB, which is fairly typical for an 18V impact wrench. The motor produces a loud whirring noise when running, especially under load. This is far from quiet, but about average for this type of power tool. Users should wear appropriate hearing protection when operating it for extended periods to avoid exposure to the high noise levels. The noise may be an issue if using the DTW190Z regularly indoors or in noise-sensitive environments. While it's not as quiet as some lower-powered impact drivers, the noise level is comparable to similar 18V impact wrenches from other brands. Overall, the noise is noticeable and warrants ear protection, but isn't out of the ordinary for this class of tool.

Accessories

The Makita DTW190Z impact wrench comes with minimal accessories. In the box, you get the tool itself along with a belt clip that allows you to attach it to your tool belt for easy portability at a job site.

Since this is a bare tool offering, batteries and a charger are sold separately. You'll need to purchase Makita 18V Lithium-Ion batteries to power the tool. Makita makes a wide range of battery sizes and styles, from compact 1.5Ah batteries for light duty up to 6Ah batteries for extended runtime during heavy fastening tasks. The charger is also sold separately, with options ranging from single port to multi-port simultaneous rapid chargers.

Optional accessories include impact sockets if you need to drive specific bolt sizes. Makita offers impact socket sets in standard and deep configurations, in both SAE and metric sizes. This allows you to customize your socket collection based on the fasteners you'll be working with.

For maximum versatility, the DTW190Z can also be fitted with an impact driver bit holder. This allows you to use impact rated driver bits for applications like driving screws. Makita has bit sets with popular driver bits like Phillips, slotted, Torx, and more.

So while the impact wrench itself doesn't include batteries or a charger, Makita offers a wide range of compatible accessories you can purchase to customize the tool for your needs.
