Energizer is the world’s first brand to offer a coin lithium battery with 3 lines of defense: our child-resistant packaging, a non-toxic bitter coating, and the exclusive color alert technology. Together, these features create the most comprehensive safety solution on the market to help prevent accidental ingestion and help detection.

At Energizer, we strive to provide both long-lasting performance and child safety. Through extensive testingand research, we optimized the bitterant’s formula and its application to ensure it does not compromise battery performance. Our batteries have undergone comprehensive testing across various devices, confirming the optimal placement of our safety enhancements without sacrificing performance.

While extensive research was done on devices to ensure compatibility, if for some reason you experience any performance issue, a slight rotation of the battery should resolve it.

The formula reacts within seconds when the cell interacts with saliva, meaning the child will taste the bitter coating, and the blue dye will appear in their mouth.

The dye is non-toxic food grade. Our coating contains approximately as much dye as an ounce of a sports drink. The visibility of the dye will vary based on length of exposure and cleaning applied to the child’s mouth.

The bitterant and colorant formula is applied to the negative side of the battery in a dotted half circle pattern to enable maximum performance and device compatibility.

If the colorant comes into contact with moisture, there is a possibility it will transfer to the wet surface. The intention of the colorant technology is to react with saliva, and as with all batteries, they should be handled with dry hands.

These batteries should be kept away from moisture. If they are exposed to moisture, including a humid environment, there is risk that the dye will stain other objects.

Dye staining the mouth and/or hands may be removed with repeated washing, rinsing, or tooth brushing. If dye stains a device, wipe with damp cloth and/or use a cotton swab to remove dye. The staining should not impact device performance. For all other surfaces, manufacturers of blue food coloring also recommend blotting with a paper towel, rinsing with water, applying white vinegar, and washing according to the care label.

The bitterant/colorant formula is good for one exposure. If the color/bitter coating has been partially or completely removed from a coin lithium battery, the battery should be disposed of safely and replaced. More importantly, if an ingestion attempt has been made on a coin lithium battery, parents and caregivers should be aware and take additional action to keep batteries out of the reach of children.
