Hart tool battery adapter
Hart 20V battery adapter: 2-wire vs PCB
If you own Hart 20V tools, you already know the problem. TTI discontinued Hart, and new packs are hard to find. The tools are fine. You need batteries that still exist.
A Hart 20V battery adapter lets you run those tools from a pack you can still buy. A two-pin adapter and this one are not the same device.
What 2-wire adapters do
A lot of Hart adapters only connect the two power pins. That will spin a simple motor. Listings usually say 2-wire tools only. A Hart 20V pack is cells plus a communication board. Leave that board out and many tools will not start.
What the PCB is for
We take the PCB out of an old Hart pack and build the adapter around it. Hart 20V tools that talk to the pack still see the electronics they expect, not just two power pins.
The pack you can still buy
This adapter fits HyperTough 20V packs. Charge them on a HyperTough charger. The adapter is not a charger. Don't throw old Hart packs away. Even a tired pack can still have a usable board.
Notes
- Not a Hart, TTI, Walmart, or HyperTough product.
- Not a cloned Hart pack.
- Not an adapter that puts Hart packs onto other tool brands.
FAQ
- Can I use other batteries on Hart 20V tools?
- Not by snapping them on. The connector is different, and many Hart tools look for the pack's electronics. That is what the adapter is for. Right now it fits HyperTough 20V.
- Why don't 2-wire Hart adapters work on every tool?
- They only connect the two power pins and skip the pack board. Some simple tools run that way. Don't count on it for every Hart 20V tool.
- Does KeepYourTools.com sell Hart batteries?
- No. TTI discontinued Hart. We build a Hart 20V battery adapter. Don't throw old complete packs away.
