BitterBlock® – For the Safety Our Children Deserve.

A bitter protective layer against the accidental swallowing of lithium button cells. Effective. Harmless. Safe.

Why BitterBlock®?

Lithium button cells are small, powerful – and can be dangerous in the wrong hands. If swallowed by children, they can cause severe injuries within a very short time, in the worst case even life-threatening.

The solution: BitterBlock® – an extremely bitter but completely harmless coating made from denatonium benzoate. Applied as an ultra-thin layer on our batteries, it produces an intense, unpleasant taste if it comes into contact with the mouth. This is designed to make children immediately spit the battery out.

Your benefits at a glance:

  • Full performance: No impact on battery function
  • Safe: No health risks
  • Extra protection: Complements existing safety mechanisms

Where BitterBlock® Protects

Button cells are found today in countless everyday devices – often in places you wouldn’t expect: remote controls, toys, car keys, kitchen scales, or flashing decorative items. Many of these devices are left openly around the home, in drawers or on tables – and thus within children’s reach.

The small, smooth design makes lithium button cells particularly tricky: they are easy to overlook and can quickly end up in the mouth. BitterBlock® provides crucial extra protection – right at the moment when it is needed most.

More Than Just Bitter – Our Safety Concept

BitterBlock® is an important element in a multi-level protection system that helps keep children safe from the dangers of lithium button cells. The bitter coating works alongside other established safety measures such as child-resistant packaging and clearly visible warning labels.

Our safety concept at a glance:

  • Bitter coating: The extremely bitter taste triggers a rejection reflex – children quickly spit the battery out.
  • Child-resistant packaging: Special blister packs that can only be opened with scissors.
  • Clear warnings: Prominent safety information on both the battery and the packaging.

What You Can Do – 3 Simple Safety Steps

  1. Store batteries safely
  • Always keep them out of reach of children and pets.
  • Ideally store them in locked cupboards or containers.
  1. Secure devices
  • Check if the battery compartment has a child-resistant lock.
  • If not: additionally secure it (e.g., with tape).
  1. Dispose of used batteries safely
  • Cover both terminals with tape.
  • Collect them in a closed container.
  • Take them to an appropriate collection point (e.g., in-store recycling boxes).
