Hi there,

This article (from Circuit Cellar) may help you kick-start your project.
This article tells you how-to build the battery load/charge analyzer (using the Motorola MC68HC705c8 microcontroller)

... so it seems to be as I thought! there's nothing to determine the battery capacity simply connecting without caharge or discharge it!
It's ok...thanks
