[D5318 Laptop battery circuitry]

Hi all,

Can you help me to find a circuit diagram for a D5318 (dell Inspiron 6000 battery) and is there a date stamp programed into these battery on-board circuits or it could still be used if the cells are replaced regardless of their age?

Any input appreciated.

[1 Simple question about led drivers]

How far you've gone ahead with your LED driver project but to answer your query you only need to regulate the current (use current gen. / reg.) :o and the voltage will be taken care of by the LED itself as long as the supply voltage exceeds the voltage across LED (@/<2v) + min voltage across current regulator required. ::) If you use a micro to drive then use current limiting resistor.
