Battery Finder16 platforms

Does this battery fit my tool?

Every brand locks you into its own battery slot — and the moment you mix Makita, DeWalt, Bosch or Milwaukee, nothing clicks. This finder shows whether your battery drops straight onto a tool, needs a cheap third-party adapter, or simply can't work — so you stop buying batteries that strand on a shelf.

Fits directly, fits with a named adapter (with a buy link), or doesn't fit — with the reason.

Häufige Fragen

Can I use a Makita battery on a DeWalt tool?

Not natively — Makita and DeWalt use different battery slots and contacts. But cheap third-party adapters exist for the popular directions (Makita→DeWalt, DeWalt→Makita, Milwaukee→Makita and so on). They pass power only: you still charge the battery on its own brand's charger, and the adapter adds a bit of length. This finder tells you which directions have a known adapter.

Do cross-brand battery adapters damage tools?

A decent adapter just routes power from the battery's contacts to the tool's contacts, so for basic drills, grinders and saws it's fine. The caveats: adapters don't carry the smart communication some tools use, so fuel gauges or tool-specific protections may not work; high-draw tools can sag if the battery is small; and a long adapter changes the balance. For occasional use they're a great way to avoid buying a second battery ecosystem.

Why don't two batteries from the same brand fit each other?

Brands run several separate systems. Makita LXT (18V) and XGT (40V) use different slots. Bosch's blue Professional and green Home lines do not share batteries. Milwaukee M18 and M12 are different platforms. Same logo doesn't mean same battery — always match the exact system name, not just the brand.

What's the deal with DeWalt FlexVolt?

FlexVolt batteries are clever: they automatically switch between 54V and 18V/20V depending on the tool, so a FlexVolt battery runs both FlexVolt tools and regular DeWalt XR tools. It doesn't work the other way — a standard XR battery can't drive a FlexVolt tool's high-power mode.

Which platform should I commit to?

Pick the system that has the tools you'll actually buy and is easy to get batteries for locally. Makita LXT and DeWalt XR have the widest tool ranges; Milwaukee M18 is strong for trades; Einhell, Ryobi and Parkside (Lidl) give the best value for DIY. Once you own three or four batteries on a platform, switching gets expensive — so the second purchase matters more than the first.

Mixing cordless batteries — what actually works

Battery platforms are the real lock-in of cordless tools. Here's what fits, what needs an adapter, and where to stop.

🔋

The platform is the lock-in

You don't really buy a brand of tools — you buy into a battery platform. The first cordless drill is cheap; the trap is the fourth tool, by which point switching brands means re-buying every battery and charger. Choose the platform before you fall in love with one tool.

🔁

Adapters bridge brands — for power

Third-party adapters let a Makita battery run a DeWalt tool and vice versa. They route power through, which is all a basic drill or grinder needs. What they don't carry is the smart communication newer tools use for fuel gauges and protection — so treat adapters as a budget bridge, not a permanent setup for premium gear.

⚠️

Same brand ≠ same battery

Makita LXT and XGT, Bosch blue and green, Milwaukee M18 and M12 — these share a logo but not a slot. The single most common cordless mistake is buying a battery that matches the brand on the box but not the system. Always read the system name.

⚡

Match the battery to the load

A tiny 2 Ah battery on a circular saw will sag and cut out; a big 5–6 Ah pack on a screwdriver is just dead weight. High-draw tools (saws, grinders, leaf blowers) want high-amp-hour, high-output cells; light tools are happy with compact packs. Adapters don't change this — the battery still has to supply the current.

🤝

Some brands deliberately share

Metabo's CAS (Cordless Alliance System) is shared by Mafell, Collomix, Rokamat and others — one 18V battery across all of them, no adapter. Bosch's green Home line is cross-compatible under 'Power for All' with several garden brands. Where a real alliance exists, you get cross-brand fit without the adapter caveats.

💶

Where the value really is

For trades, the big three (Makita, DeWalt, Milwaukee) earn their price in tool range and durability. For home use, Einhell Power X-Change, Ryobi ONE+ and Parkside X20V (Lidl) deliver 80% of the capability for a fraction of the cost — and they each keep one battery across a huge range, which is the whole point.
