Power Tool Battery Compatibility – What Fits What?

One of the most common questions is: are power tool batteries interchangeable? Most modern cordless tools use manufacturer-specific battery platforms, commonly including 18V systems and batteries marketed as 20V MAX. Batteries may be interchangeable between compatible tools within the same platform, but compatibility between different manufacturers is not normally guaranteed.

Xcat Marketplace brings together replacement and compatible power tool batteries from Xcat and independent sellers. Buyers can compare voltage, capacity, battery connections and supported tool platforms before choosing a suitable replacement.

Discover Xcat-Branded Replacement Batteries

Alongside products from independent marketplace sellers, Xcat offers its own range of Xcat-branded compatible replacement batteries. These batteries provide an alternative to original manufacturer products for specified cordless tool systems. Always check the individual product listing for supported battery models, tool compatibility, capacity and charging requirements.

Xcat-branded compatible batteries are independent replacement products and are not manufactured or endorsed by the original tool manufacturers.

Choosing the Right Replacement Power Tool Battery

When replacing a cordless tool battery, it is important to check more than the voltage printed on the casing. Battery compatibility depends on the tool platform, electrical requirements, connector design and supported charging system.

Common replacement battery capacities include 2Ah, 3Ah, 4Ah, 5Ah and higher-capacity options. Higher-capacity batteries can provide longer operating time between charges when used with compatible equipment.

Larger-capacity batteries may be particularly useful for demanding cordless tools, including combi drills, circular saws, impact drivers and grinders.

Lithium-Ion Power Tool Batteries

Modern cordless power tools commonly use lithium-ion battery technology. Lithium-ion batteries offer rechargeable power storage in a compact format and are available in different voltage and capacity configurations.

Battery construction, protection systems and charging compatibility vary between manufacturers and products. Buyers should consult the individual listing and manufacturer guidance before purchasing or charging a replacement battery.

Browse compatible replacement batteries for popular cordless tool systems, including:

• DeWalt XR 18V and 20V MAX platforms

Compatibility depends on the individual battery model. Not all batteries fit every tool or charger within a manufacturer's product range. Always confirm the supported model numbers and connection type before ordering.

Power Tool Guides, Compatibility Information and Calculators

Xcat provides practical guides and calculators to help buyers choose suitable tools, batteries and accessories. For drilling applications, our Pilot Hole Size Calculator helps determine suitable pilot hole sizes for different screw and material combinations.

Choosing a compatible battery with sufficient capacity can also help reduce interruptions during extended drilling and other cordless tool operations.
