Safety Guidelines - Lithium Coin Cell Batteries

Please observe the following warnings strictly. If misused, the batteries* may explode or leak, causing injury or damage to the equipment.
  • Keep batteries out of the reach of children, especially those batteries fitting within the limits of the truncated cylinder defined in ISO/DP 8124/2.2 page 17. In case of ingestion of a cell or battery, the person involved should seek medical assistance immediately.
  • Items or equipment intended for use by children should have battery compartments that are tamper-proof, like a screw-on compartment.
  • Depleted batteries should be removed from the item or equipment.
  • Circuits of equipment using alternative power should be designed to eliminate the possibility of the battery being overcharged (see UL standard for diode use).
  • The batteries must be inserted into the item or equipment with the correct polarity (+ and -).
  • Do not attempt to revive used batteries by heating, charging or other means.
  • Do not dispose of batteries in fire.
  • Do not dismantle batteries.
  • Replace all batteries of a set at the same time. Newly purchased batteries should not be mixed with partially used ones. Batteries of different electrochemical systems, grades or brands should also not be mixed. Doing so may result in some batteries being driven beyond their normal exhaustion point and therefore increase the potential of the battery to leak.
  • Do not short circuit batteries.
  • Avoid directly soldering to batteries.
  • Do not expose batteries to high temperatures, moisture, or direct sunlight.
  • When discarding batteries with solder tags, insulate the tags by wrapping them with insulating tape.
  • Improper welding can damage the internal components of batteries and impair their performance.
  • Do not place batteries on a conductive surface (anti-static work mat, packaging bag, or form trays) as it can cause the battery to short.

*Applicable to all lithium coin cells such as the CR2032 battery, CR2025, and CR2016
