While batteries have always been regulated, the regulations are more rigid now.

Lead and mercury in batteries have long been recognized as an environmental problem. EU Directives date back to 1991. In 2006 the EU has passed the new directive 2006/66/EC on batteries and accumulators and waste batteries and accumulators and repealing Directive 91/157/EEC. This directive replaces the previous directives.

The prohibitions:

1. Without prejudice to Directive 2000/53/EC, Member States shall prohibit the placing on the market of:
   1. all batteries or accumulators, whether or not incorporated into appliances, that contain more than 0,0005 % of mercury by weight; and
   2. portable batteries or accumulators, including those incorporated into appliances, that contain more than 0,002 % of cadmium by weight.
2. The prohibition set out in paragraph 1(a) shall not apply to button cells with a mercury content of no more than 2 % by weight.

This translates to less than 5 PPM (2% on button) of Mercury and less than 20 PPM Cadmium in the total weight of the battery. This doesn't appear to be at the homogenous level as in the RoHS Directive. Also, the battery or battery packaging must have the crossed out wheelie-bin.

The only limitations are use in military and space applications. If implemented on time, it is expected to be law in 2009. The key concept: all batteries will be recycled.

Mouser is planning ahead.
We are contacting our battery suppliers and gauging the awareness in the industry. As the directive and legislation develops, Mouser will implement compliance projects. We currently recycle all waste or scrap batteries through local recyclers.
