Craftsman 19.2V (C3 / DieHard) Battery Adapters
The Craftsman C3 19.2V platform ran for years and is thoroughly discontinued, so a lot of these tools are working fine with nothing to power them.
4 adapters bring a current battery to them — which for a tool that has already lasted this long is usually worth doing.

Craftsman 19.2V C3 Ni-Cd questions
Why do some batteries say 18V and others 20V?
They are the same class of battery, measured at two different moments. Five lithium cells in series read about 20V fresh off the charger with nothing drawing from them, and settle to about 18V once a tool is running. A brand that prints 20V is quoting the first figure and one that prints 18V is quoting the second. That is why an adapter between an "18V" platform and a "20V" platform works: there is no conversion to do.
Will this fit my other Craftsman batteries?
Only Craftsman 19.2V C3 Ni-Cd batteries. Craftsman also sells Craftsman 20V, Craftsman 20V Bolt-On, and those use a different socket — same brand, different rail and terminals, so they need their own adapter. Compare the sliding rail on your battery against the photos before ordering.
How do I find the right adapter on this page?
Use the selector at the top: pick the platform on the other side of the pair and it takes you straight to the one adapter that joins them. Every combination in that list is one we actually make, so if it is there, it exists.
Can I use a Craftsman 19.2V C3 Ni-Cd battery on another brand’s tool?
Not with an adapter from us. Craftsman 19.2V C3 Ni-Cd works as the tool side only here — we make adapters that let other brands’ batteries run Craftsman 19.2V C3 Ni-Cd tools, not the reverse.
Can I charge a Craftsman 19.2V C3 Ni-Cd battery through the adapter?
No. The adapter carries current from the battery to the tool and does nothing else — there is no charging circuit inside it. Keep charging Craftsman 19.2V C3 Ni-Cd batteries on their usual Craftsman charger.
Will an adapter damage my Craftsman 19.2V C3 Ni-Cd battery or my tool?
Treat it the way you would on its own tool. Craftsman 19.2V C3 Ni-Cd batteries have no electronic protection built in, so nothing can warn you when the battery is empty. Stop when it slows down rather than running it flat, and stop using the adapter if it becomes unusually hot or the contacts look damaged.
Does it work with third-party Craftsman batteries?
Usually. What matters is the socket, not the badge: if the battery slides onto a Craftsman 19.2V C3 Ni-Cd tool and locks the way an original does, the adapter will take it. Aftermarket batteries do vary in moulding, so if yours looks unusual send us a photo and we will check before you order.
