Hart 20V batteries
Hart 20V packs are the bottleneck. Replacement cells are not the honest fix.
People searching for a Hart 20V battery pack, Hart 20V lithium battery, or Hart tool battery replacement are hitting empty shelves. Hart is out of Walmart. Third-party packs are inconsistent. KeepYourTools is a different answer: keep the Hart tools, change the pack ecosystem.
What happened to Hart batteries?
Hart was a Walmart-exclusive power tool line. When that lineup was discontinued, the tools people already bought did not vanish — the reliable path to new 20V packs did. Chargers and leftover kits still appear, then go out of stock. That is the search demand we are answering.
We are not selling Hart packs
KeepYourTools will not be a gray-market Hart battery store. Cloning a pack without the original electronics is how you get tools that randomly refuse to start. Our product is a HyperTough 20V to Hart 20V adapter that reuses the Hart pack PCB.
If you still have Hart packs
Hold onto them. Even tired packs can donate the board the adapter needs. At launch, sending Hart 20V packs with your order will earn a PayPal refund or credit after inspection. That program is how we keep building adapters that actually handshake with Hart tools.
If you are shopping HyperTough instead
HyperTough 20V is the pack family this adapter is designed to accept. Buy HyperTough 20V batteries and chargers for the new energy side. Keep Hart 20V tools on the tool side. Coming soon on KeepYourTools.com.
