mercury and cadmium free batteries

Batteries without mercury adhere to environmental protection standards. Other materials are used to replace the additives inside. In fact, this is a relief because even though these batteries are toxic and have high levels of heavy metals, their toxicity is relatively low.

Mercury-free batteries are currently safe to use and meet environmental protection standards. But the environment is the sole issue! Batteries are also contaminated with mercury and other heavy metals, and it is still harmful if it comes into contact with food or the mouth.
