Positec 18-20V (ToolPro, Worx, Rockwell) batteries

Positec makes packs sold under several brands. A 2026 owner report says ToolPro 18V packs are Positec-made, per Supercheap Auto manuals.

Watch out: Positec packs come in 3-notch and 4-notch generations. Chargers are keyed to a generation, and some newer packs lack a temperature pin so will not charge on older chargers. Check your pack and charger generation. ToolPro 20V is a different, wider connector and is not part of this family.
