Available from Wednesday in 20mm 2032, 2025 and 2016 sizes, the batteries replace last year's 3in1 Child Shield line, which Energizer is discontinuing.
Energizer says independent testing supports claims the proprietary alloy prevents digestive-tract burns if swallowed, though doctors caution the batteries can still choke or obstruct children and are not safe to ingest.
More than 3,500 people in the US swallow button batteries annually, while global complications reach 3,000 to 8,000 cases; the product also includes child-resistant packaging, blue dye and a bitter coating.
With burn risks gone, do new child-safe batteries create a false sense of security, masking other serious ingestion dangers?
Energizer's 'burn-proof' battery is incompatible with Apple AirTags. Does this safety feature compromise the battery's basic function?
