Power Tool Battery Compatibility Chart – Find What Fits What
Ever wondered if your DeWalt 20V battery can fit your Makita tool? Or whether a Ryobi One+ pack could power your Craftsman V20 drill? You’re not alone. Tool battery compatibility is one of the most confusing parts of the cordless tool world — and that’s exactly why we built this guide and our Battery Finder tool below.

Why a Power Tool Battery Compatibility Chart Matters
Every tool brand wants to keep you inside its ecosystem. Even when two batteries share the same voltage, which are actually identical in power — their connectors and locking tabs are intentionally different. That means a Makita 18V battery won’t physically fit a Milwaukee 18V (M18) tool, even though they both run at the same voltage.
For professionals and DIYers who already own multiple brands, this creates unnecessary limits. You might have five charged batteries sitting on the bench, yet none fit the tool you need right now. That’s where understanding compatibility — and using the right battery adapter — changes everything.
How Battery Adapters Make It Possible
Battery adapters act as a bridge between two systems. They safely connect a battery from one brand to a tool from another, letting you power more tools with what you already own. For example:
- Use a Milwaukee M18 battery on a DeWalt 20V tool
- Run your Makita 18V batteries on Bosch 18V tools
- Connect a RIDGID / AEG 18V battery to a Craftsman V20 tool
Each adapter is designed with precision terminals for efficient current flow and a molded ABS housing for durability. No wiring, no modifications — just click and go.
Understanding Compatibility Between Brands
Voltage is only one piece of the puzzle. The shape of the connector, the position of the locking tabs, and the placement of the power terminals all differ between brands. That’s why you can’t mix batteries directly — but with the right adapter, you can often bridge those differences safely.
Our lineup covers most major 18V and 20V systems, including DeWalt, Milwaukee, Makita, Bosch, Ryobi, RIDGID, Bauer, Hercules, Craftsman, and more. If your combination isn’t listed yet, contact us — we may already be developing it or can help you find the right solution.
