Hi,

Like everyone, I've a number of mobile phones which I don't use
anymore. I was thinking I could make use of those rechargeable
batteries which are going to waste. How do I put them to use in small
devices like portable radios, toys. They seem to have 3 battery
terminals -
how do I wire them ? What is the voltage ? How to ensure that I
don't blow my radio up ?

Thanks in advance for your inputs,

Mike Tan
