Hart 20V batteries
Hart 20V packs are getting scarce.
TTI discontinued Hart. Official 20V packs are getting hard to find. Leftover stock still turns up, but it will not last.
We don't sell Hart batteries. A Hart 20V battery adapter lets you keep the tools and buy packs that are still on shelves.
Hart battery replacement
TTI is not making a replacement Hart pack. If you want the 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. Hold onto them. Temporary introductory offer: $59 total, shipped. No core. The usual price with no core is $90. Or the adapter is $59 after you send one complete pack back ($99 at checkout, $40 PayPal after we inspect). Extra complete packs are $20 each after we inspect. Dead cells are fine. Incomplete packs are not paid.
HyperTough 20V instead
That is the pack this adapter is built for right now. Charge HyperTough packs on a HyperTough charger. You can buy more when you need them.
2-wire vs PCB
A cheap adapter that only lists 2-wire tools is skipping the pack electronics. Many Hart 20V tools look for that board. Why 2-wire adapters fail on those tools.
