Find a supplier
No exact store listing is recorded for this part. Continue with the documented system parts record, the supplier directory, or contact the affiliated UK store or US store to identify the correct regional SKU. An enquiry is not a claim of current stock or that another SKU is a substitute.

Listing ≠ endorsement. Confirm availability, approval status and source evidence before purchase or regulated workplace use.
Notes
Discontinued standard battery of the legacy Adflo era (a Heavy-Duty sibling 837621 also existed). Owners searching this number today should move along the supersession chain to the current Li-ion packs: 837630 (EMEA standard), 837631 (EMEA Heavy-Duty) or 35-1099-07 (US) — and note the current packs pair with charger 833111, not the legacy 833101.
