Because the electronic scale needs to output a large current at the moment of weighing, and the standby time is long, if the power is insufficient, the number will be wrong. In order to avoid weighing errors and frequent battery replacement, it is necessary to use batteries with lasting power. The No.5 battery (AA, R6) is one of the battery types, with a general size of 14mm and a height of 50 mm.. Because of its small size and moderate capacity, the 5th battery is widely used in many small household appliances and digital products.
