How we check
Every entry is checked by hand against the manufacturer's own listing and the physical battery interface before it is published. We never auto-generate compatibility claims.
Platform coverage
We only publish a platform once at least one row has been hand-verified. Live now:
- DeWalt 20V MAX
- Milwaukee M18
- Ryobi 18V ONE+
- Makita 18V LXT
- HART 20V
Not yet covered (no hand-verified row exists): Kobalt 24V (Lowe's), Bauer 20V (Harbor Freight), Craftsman V20. We add a platform as soon as we can verify a row for it — tell usif you'd like one prioritized.
