The Infinite Envie AA Rechargeable NiMH Batteries (1.2V, 2100mAh) are sealed nickel-metal hydride (NiMH) batteries. While a specific Material Safety Data Sheet (MSDS) for this exact product isn't readily available, general safety information for NiMH batteries can be referenced from similar products.

🔒 Safety Overview
Normal Use: Sealed NiMH batteries are generally considered non-hazardous under normal operating conditions. They are designed to prevent the release of hazardous materials during typical use.

Abuse or Damage: If the battery is subjected to misuse—such as overcharging, deep discharging, short-circuiting, crushing, or exposure to fire—there is a risk of electrolyte leakage. The electrolyte may contain potassium hydroxide, which is corrosive and can cause skin and eye irritation upon contact.

🔧 Handling and Storage Recommendations
Avoid Physical Damage: Do not puncture, crush, or incinerate the batteries.

Temperature Considerations: Store in a cool, dry place away from direct sunlight and heat sources.

Short-Circuit Prevention: Do not store batteries loosely or in a manner where they can come into contact with metal objects, which could cause a short circuit.

Proper Disposal: Recycle used batteries in accordance with local regulations.
