Frequently Asked Questions

Why is Energizer’s safety approach better than what’s currently in the market?

Energizer is the world’s first brand to offer 3in1 Child Shield coin lithium batteries with 3 lines defense: our child-resistant packaging, a non-toxic bitter coating, and the exclusive Color Alert technology. Together, these features help prevent accidental ingestion and help detection.

At Energizer, we strive to provide both long-lasting performance with child safety features. Through extensive testing and research, we developed a bitterant formula with the Color Alert and optimized its application to ensure it does not compromise battery performance. Our batteries have undergone comprehensive testing across various devices to ensure compatibility. Recently, we updated the coating application to the positive side of the cell in a full dotted circle shape, we optimized the placement of our safety features to ensure performance.

In-stores, you may still find the negative side coating (back side of the battery cell), which is as effective in terms of safety features, just might require a slight rotation of the battery to connect with devices.

Where is the colourant technology applied on the battery?

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

What is the reaction time once the cell interacts with saliva?

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.

Is the colourant activated by any moisture?

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

How long will the child’s mouth remain blue without being treated?

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.

Is there a possibility of the dye staining clothing or furniture?

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 colouring also recommend blotting with a paper towel, rinsing with water, applying white vinegar, and washing according to the care label.

How many exposures will the bitterant/colourant formula last?

The bitterant/colourant formula is good for one exposure. If the colour/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.
