Energizer CR2450 Lithium Coin Battery: Child Safety and Australian Compliance
Coin batteries can cause serious internal injuries if swallowed, which is why safe storage matters. Since 22 June 2022 the ACCC has enforced mandatory button and coin battery safety and information standards in Australia, requiring child-resistant packaging and clear warnings.
This Energizer CR2450 is supplied in a child-resistant blister that releases one cell at a time.
Always keep batteries, new and used, out of reach of children. If a battery is swallowed or placed in the nose or ear, seek medical help immediately or call the Poisons Information Centre on 13 11 26. For more on the current rules, read our guide to the button and coin battery safety standards.
