Remarques

The upgrade option in the Adflo battery family. EMEA numbering: the standard Li-ion battery is 837630 and this HD battery is 837631; the US-market standard battery is 35-1099-07. Charger 833111 (83 31 11) serves the EMEA Li-ion packs. The "fits all Adflo systems" claim is distributor-evidenced; the datasheet confirms it as a current manufacturer-listed Adflo part.
