RIDGID Battery Compatibility – Overview

RIDGID has produced cordless power tools across multiple battery voltages, some of which are now discontinued. Because of this, RIDGID batteries are not universally compatible, even within the same brand.

This guide covers:

All RIDGID cordless battery voltages
Which platforms are discontinued
What is and isn’t interchangeable
When battery adapters can be used

RIDGID Cordless Battery Voltages (All Generations)

RIDGID has released cordless tools using three distinct battery voltages:

12V – discontinued
14.4V – discontinued
18V – current platform

These platforms are electrically and physically incompatible with each other.

RIDGID 12V Battery Compatibility (Discontinued)

RIDGID previously offered a 12V cordless lineup, typically aimed at compact tools.

Key facts:

Designed exclusively for RIDGID 12V tools
Platform is fully discontinued
Batteries are not compatible with 14.4V or 18V tools
No official upgrade or backward compatibility exists

If you own RIDGID 12V tools today:

Battery availability is limited
Cross-voltage use is not possible
Adapters between RIDGID 12V and other RIDGID platforms generally do not exist

RIDGID 14.4V Battery Compatibility (Discontinued)

RIDGID’s 14.4V platform predates the modern 18V lineup.

Key facts:

Used on older RIDGID cordless tools
Offered historically in Ni-Cd and Li-ion versions (varies by model)
Platform is fully discontinued
Not compatible with RIDGID 12V or 18V tools

14.4V tools cannot be upgraded to 18V batteries without unsafe modifications and should not be adapted directly.

RIDGID 18V Battery Compatibility (Current Platform)

RIDGID’s current cordless tools run on the 18V battery platform.

Within the RIDGID 18V ecosystem:

RIDGID 18V batteries are designed to work only with RIDGID 18V tools
Higher capacity (Ah) batteries provide longer runtime, not higher voltage
Batteries from older RIDGID platforms (12V, 14.4V) are not compatible

This is the only actively supported RIDGID cordless platform today.

18V Tool	12V / 14.4V	❌ No

Using Battery Adapters With RIDGID Tools

By default, RIDGID batteries are not compatible with other brands, and batteries from other brands will not fit RIDGID tools directly.

However, battery adapters can allow a battery from another brand to power a RIDGID cordless tool when the adapter is designed for that specific pairing. In some cases, the adapter can also regulate or convert power appropriately, meaning the nominal voltage does not necessarily need to match.

Depending on the design, an adapter may:

Step voltage up or down as required
Regulate current delivery
Integrate protection circuitry (over-current, under-voltage, thermal limits)

Note: Not all adapters are equal. Compatibility depends on the exact battery → tool pairing and the adapter’s internal design.

Important Disclaimer (Non-Official Product)

Battery adapters are third-party accessories. They are not manufactured by, not licensed by, and not endorsed by RIDGID.

Using a third-party adapter may void the tool or battery warranty and can fall outside manufacturer specifications. Always ensure the adapter is explicitly designed for your exact tool and battery type.

Summary: RIDGID Battery Compatibility

RIDGID has used 12V, 14.4V, and 18V cordless platforms
12V and 14.4V are discontinued
Platforms are not cross-compatible
RIDGID batteries do not natively work with other brands
Battery adapters can enable cross-brand use when properly designed for a specific battery → tool pairing
