Maintenance and Storage
Proper maintenance and storage can help maximize the lifespan and performance of your Sony CR 1616B1A battery.
- Storage: Store unused batteries in their original packaging in a cool, dry place, away from direct sunlight and extreme temperatures. Avoid storing batteries in humid environments.
- Temperature: Optimal operating and storage temperature ranges are typically between -20°C to +60°C (-4°F to +140°F). Extreme temperatures can reduce battery life.
- Cleaning: If battery terminals appear dirty, gently wipe them with a clean, dry cloth. Do not use water or chemical cleaners.
- Disposal: Dispose of used batteries according to local regulations. Do not dispose of batteries in household waste or by incineration. Many retailers and recycling centers offer battery recycling programs.
