기능

• High-capacity alkaline batteries.
• The use of a pressure reducing valve on the gasket surface prevents bursting, and the use of a washer (insulating ring) prevents short circuit and liquid leakage, so it lasts a long time.
• Since it is made of ultra-small zinc compared to ordinary alkaline batteries, the contact area with the electrolyte is larger, and the electric generation area by the chemical reaction is larger, so it lasts longer.
• The recommended expiration date is 10 years after manufacture.
