Will the Bosch GBA18V40 18V CORE18V 4Ah battery work with the Bosch GAL12V/18V-80 12V/18V multi-voltage fast charger?
Yes. Both use Bosch 18V battery platform (incl. CORE18V, PROFACTOR).
Both records are reviewed against the manufacturers' sources; sources last checked 2026-10-14. Informational only: confirm with the manufacturer before buying.
Why
- ✓ Both use Bosch 18V battery platform (incl. CORE18V, PROFACTOR).
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.
