# Hart 20V Batteries | Replacement Path

Hart 20V batteries are getting hard to find because TTI discontinued Hart. KeepYourTools.com does not sell Hart packs.

TTI is not making a replacement Hart pack. Leftover stock still turns up, but it will not last. If you want Hart 20V tools to keep working, you need an adapter and a pack you can still restock.

Don't throw old Hart packs away. Even tired packs can still have a usable board. Dead cells are fine. Incomplete packs are not paid.

Right now this adapter is built for HyperTough 20V. Charge HyperTough packs on a HyperTough charger.

A cheap adapter that only lists 2-wire tools is skipping the pack electronics. Many Hart 20V tools look for that board. See [2-wire vs PCB](https://keepyourtools.com/hart-tool-battery-adapter.md).
