It comes as standard with an internal rechargeable battery which is charged with a 220v mains lead. The maximum weight is 15kg in steps of 1g. There is a dual display (Back & Front) which would allow two people use the scales at the same time if using the scale to pre-pack. The scale can weigh in Kg, Grams, “Lb’s & Decimal Lb’s” and “Lb’s & Oz”. See the specification tab for more details.
