Good to know
  • PROFACTOR tools work with any Bosch 18V battery, but Bosch recommends high-output CORE18V packs (GBA18V60/GBA18V80/GBA18V120) for full PROFACTOR performance.
  • Bosch says all Bosch Professional 18V batteries sold since 2008 are compatible with AMPShare tools from partner brands (e.g., Fein, Rothenberger, Wagner) and the other way round.
  • Not compatible with Bosch 12V Max batteries. The GAL12V/18V-80 charger charges both.
