Are DeWalt and Porter-Cable 20V Batteries Interchangeable?

Yes — fully. DeWalt 20V MAX and Porter-Cable 20V MAX batteries use the same slide-pack connector, the same Li-ion cell chemistry, and the same charge protocol. A DeWalt battery drops into a Porter-Cable tool. A Porter-Cable battery drops into a DeWalt tool. Their chargers cross-charge in both directions. Everything below is the full picture — what swaps, what to watch for, and whether adding more Porter-Cable batteries is worth it going forward.

Why They're Interchangeable — Same Platform, Different Badge

Both brands are owned by Stanley Black & Decker. DeWalt 20V MAX is the pro-tier line; Porter-Cable 20V MAX is the value line built on the same electrical and physical platform.

The "20V MAX" label is marketing — both brands' packs are nominally 18V. The 20V rating reflects max cell voltage, not running voltage. That's standard industry practice, and both brands do it identically. Same connector. Same Li-ion cell chemistry. Same charge protocol. That's why they swap.

If you're wondering why DeWalt batteries cost more: it's not the connector — it's cell quality, capacity options, and brand positioning. The platform itself is shared.

Full Compatibility at a Glance

For charger cross-compatibility, DeWalt chargers (DCB107, DCB112, DCB115, DCB118) work with Porter-Cable 20V MAX packs. The reverse works too — a Porter-Cable charger will top off a DeWalt 20V battery. One real caveat worth knowing: the Porter-Cable 20V charger — such as the PCC692L — outputs 2.0A, which is higher than the DeWalt DCB112's 1.25A. Cross-charging with a Porter-Cable charger is the faster option. Either way, charger output only affects charge speed, not compatibility.

Does a "Better" DeWalt Battery Hurt a Porter-Cable Tool?

No. A higher-Ah DeWalt XR pack in a Porter-Cable tool means more runtime — that's it. The motor draws what it needs at the tool's rated voltage. It doesn't know or care what brand the battery is. No overload, no heat, no compatibility conflict.

Going the other direction — a smaller Porter-Cable pack in a DeWalt tool — shortens your runtime. That's the only trade-off.

Don't expect the Porter-Cable tool to suddenly perform like a DeWalt tool with a DeWalt battery. The tool's motor and electronics set the performance ceiling. A bigger battery extends how long you run at that ceiling, not how high it is.

DeWalt 20V MAX Accessories Also Work With Porter-Cable Batteries

This is the part most people miss. Because it's the same 20V MAX slide-pack platform, battery-powered accessories snap onto Porter-Cable packs the same way they do DeWalt packs.

That means inverters and USB chargers that ride on a 20V MAX battery work directly with your Porter-Cable packs — no adapter, no workaround.

The 150W power inverter and USB-C fast charger both plug straight onto a Porter-Cable 20V MAX battery. If you've got PC packs sitting around between jobs, they're already compatible with the same accessories DeWalt users run.

Should You Keep Buying Porter-Cable 20V Batteries, or Switch to DeWalt?

Straight answer: for new purchases or platform expansion, DeWalt 20V MAX is the smarter bet.

Porter-Cable's 20V MAX cordless tool lineup has contracted, with a noticeably narrower selection of active tools and limited new launches. The action in SBD's cordless portfolio is moving toward DeWalt, not Porter-Cable. More active tools, a bigger accessory ecosystem, and better long-term support.

That said — your existing Porter-Cable 20V packs aren't going anywhere. They work across both brands now, and the 20V MAX battery standard isn't changing anytime soon. No need to throw them out or replace them. Just don't build a bigger investment in the Porter-Cable battery ecosystem if you're starting fresh.

If you're ready to add packs, which DeWalt 20V battery to buy breaks down which DeWalt 20V battery makes sense depending on how you use your tools.

The same platform logic applies to Black+Decker and Craftsman V20 — see Black+Decker battery compatibility and Craftsman V20 compatibility for those compatibility breakdowns.

FAQ

Will a DeWalt 20V battery fit a Porter-Cable 20V tool?

Yes. Same slide-pack connector, same voltage. It drops in and works normally. A higher-Ah DeWalt battery gives you more runtime in that Porter-Cable tool — nothing more, nothing less.

Can I charge a Porter-Cable 20V battery with a DeWalt charger?

Yes. DeWalt 20V MAX chargers — including the DCB107, DCB112, DCB115, and DCB118 — charge Porter-Cable 20V MAX batteries. The DCB112 is rated for 20V MAX platform batteries, and Porter-Cable 20V MAX packs are part of that platform. Same connector, same charge protocol.

Are Porter-Cable and DeWalt owned by the same company?

Yes — both are Stanley Black & Decker brands. DeWalt is the pro line. Porter-Cable is the value line. Their 20V MAX battery platforms are intentionally shared.

Do DeWalt XR batteries work in Porter-Cable 20V tools?

Yes. "XR" is DeWalt's label for extended-capacity packs — same connector, same 20V platform. Your Porter-Cable tool runs fine on an XR pack; you just get more runtime between charges.

Will a FLEXVOLT battery run Porter-Cable 20V tools?

Yes. DeWalt FLEXVOLT batteries (like the DCB612 at 12.0Ah) automatically switch between 60V and 20V depending on the tool. In a Porter-Cable 20V MAX tool, they deliver 20V. DeWalt's product page references compatibility with "DeWalt 20V MAX tools" — Porter-Cable isn't explicitly listed, but the shared platform is why it works.

Is Porter-Cable being discontinued?

The 20V MAX battery platform is shared with DeWalt and active. Porter-Cable's cordless *tool* lineup has gotten smaller, with fewer active models available than in prior years. Batteries and chargers remain available. The platform isn't dead; it's just not where SBD is growing.

Should I buy Porter-Cable or DeWalt 20V MAX batteries?

If you already own Porter-Cable tools: either brand's packs work — buy whatever's priced right at the moment. For new investment or expanding a collection from scratch, DeWalt 20V MAX has the broader active ecosystem and more accessory options long-term.

Your Porter-Cable 20V packs are already in the DeWalt ecosystem — the platform is shared, the connector is the same, and everything designed for 20V MAX slides right on. If you want to get more out of them on the jobsite, browse DeWalt collection for inverters and USB chargers that work with every pack on the platform.
