Pre-charged Nimh C Cell Batteries

The low self discharge AA batteries I installed in a String Trimmer seem to have lost their charge after just under a year. This may be because they were left plugged into a dumb charger (the batteries are supposed to be disconnected from the cgarged when the are charged and then hold their charge). Or perhaps a year is all that can be expected in a heavy duty application from these batteries. Sub C cells, which the trimmer originally had, should offer more power.

Tenergy are offering Pre-charged Nimh C Cells on Amazon.com. The catch is that they are only 3000mAh capacity. It is likely these are actually AA cells fitted into a larger empty metal cylinder to make them up to C cell size. Other C cells are usually 5,000 to 10,000 mHa.

How many old computers are recycled?

The Australian Bureau of Statistics asked for data sources for measuring Electronic waste. There are mobile phone recycling schemes in Australia, with estimates of how many are recycled. Are there similar figures for recycling of computers and peripherals? Any suggestions would be welcome.

About all I could think of was the AIIA sponsored scheme might have some figures. ByteBack scheme (similar to the phone muster).
