For our 20mm lithium coin cell batteries, you might notice you now need a scissors to open the package … this is because Energizer is proactively addressing the threat of battery ingestion amongst children. Energizer leads the industry by being the first battery manufacturer to introduce coin lithium battery packaging that voluntarily meets the strict guidelines set by the Consumer Product Safety Commission (CPSC) for child resistance. We’re proud to help keep kids safe!
