- Do Not Dispose in Fire: Never dispose of batteries in fire, as they may explode.
- Avoid Short-Circuiting: Do not short-circuit the battery terminals. This can cause the battery to overheat and potentially leak or rupture.
- Proper Polarity: Always insert batteries with the correct polarity (+ and -) as indicated by the device.
- Disposal: Dispose of used batteries according to local regulations. Many communities have recycling programs for batteries. Do not dispose of them in household waste.
