The reason why there are so few printing points on battery labels is safety requirements and space constraints.

1. Safety requirements: The fewer printing points on the battery label take into account the safety of the battery during use. The words and symbols on the battery label must be clear and clear, and cannot be vague, unclear or misleading, otherwise it may affect the user's safety.

2. Space limitation: There are fewer printing points for battery labels because the space for battery labels is relatively limited. The battery label needs to print the battery model, voltage, capacity, production date, manufacturer and other information. It also needs to print relevant identification symbols, such as recycling symbols, dangerous goods logos, etc. In a limited space, it is necessary to reduce the number of printing points as much as possible to ensure the integrity and clarity of identification symbols and information.
