• Store batteries in a cool, dry place away from direct sunlight and extreme temperatures.
• Keep batteries in their original packaging until ready for use to prevent accidental short-circuiting.
• Do not store batteries with metal objects (e.g., keys, coins) that could short-circuit the terminals.

5.2 Disposal:

• Do not dispose of batteries in household waste.
• Recycle used batteries at designated collection points or according to local regulations. Many retailers offer battery recycling programs.
• Never incinerate batteries, as this can lead to explosion or release of hazardous materials.
