What is the difference between button battery cr1616 and cr1620
1. Weight difference:
The weight of the cr1616 button battery is 1.1g. The weight of the button battery cr1620 is 1.2g.
2. The difference between the maximum size (diameter*thickness):
(1) The maximum size (diameter*thickness) of the button battery cr1616 is 16.0mm*1.6mm.
(2) The maximum size (diameter*thickness) of the button battery cr1620 is 16.0mm*2.0mm.
3. Differences in nominal capacity:
(1) The nominal capacity of the button battery cr1616 is 50mAh.
(2) The nominal capacity of the button battery cr1620 is 70mAh.
1. Environmental impact of button batteries:
(1) Most of the button batteries used are mercury-free batteries, so there is no need to worry about their impact on the environment.
(2) All domestic and foreign battery monomer products sold in the market must be labeled with mercury content (the labeling method of mercury content in battery products is different from domestic environmental protection battery manufacturers, such as "low mercury", "mercury-free" or "mercury is 0 ", "mercury is 0" and other ways). When consumers buy a battery, they only need to look at the mercury content of the battery to know whether it is an environmentally friendly battery.
2. The safety risks of button batteries:
(1) Babies aged 1 to 3 who are just toddler are prone to inhalation and ingestion of button batteries. The hazard of eating button batteries is mainly caused by the electrolyte in the battery. Both acidic and alkaline electrolytes will undergo chemical reactions in the body, causing internal organs to be burned, corroded, eroded, or even perforated.
(2) When a severely corroded button battery enters the human esophagus, the metal layer on the battery surface may dissolve, and the leakage will cause internal organs to be burned, corroded, eroded, or even perforated, which will seriously endanger life.
