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.
