The other type of button cell is the LR44, which has a voltage of 1.5V. It is usually used in toys or vernier calipers. The price is 10 yuan. It uses a new generation of materials and high-quality batteries to make the battery last longer, and the battery is During use, the battery capacity loss is very low and the service life is also long. However, this kind of battery needs to be connected according to regulations in the positive and negative modes. If there is a reverse connection or the battery is short-circuited, it will cause an explosion. In order to guarantee the service life of the battery, the new battery cannot be used at the same time as the old battery.

Stainless Steel (Stainless Steel) is referred to as acid-resistant stainless steel, resistance of air, steam, water and other weak corrosive medium or stainless steel having resistance as stainless steel; and the resistance to chemical corrosion medium (acid, alkali, salt and other chemical leaching pitting) corrosion of steel known as acid-resistant steel. As the two differences in the chemical composition of leaving their corrosion resistance is different from ordinary stainless steel general impatience chemical corrosion, and acid-resistant steel are generally of a stainless steel.
So now Stainless Steel Padlock with his unique quality, it won a lot of the market, particularly in Europe, is located in the cold zone countries.
