Thank you Steve.
I confirmed that we are indeed dealing with I2C bus and the I2C specs should apply.
Indirectly you answered an other question for me which was related with the PBP’s I2C and if it can handle something like this.
As soon as I get my parts I will try both: the PBP built in I2C and built my own subroutines for each condition and call them in a main program. I’m not sure if the built in I2C commands are flexible enough for this application.
I am aware of the news on Li-ion battery but at this time I’m only trying to read info from the battery and let the charging part to the professionals.
What I was trying to relay in my other posts is the fact that with only $1.00 you can monitor your battery level and take advantage of a large selection of small form factor / high capacity smart batteries (not necessarily Li-ion) to use in your projects. All I want at this time is the peace of mind that my project will never run the batteries dead and I have an advance warning when the batteries are low. I also want to put some of my "almost never used" smart batteries to do something more useful than collecting dust.
I will do some more digging and post the results.
Any other input is more then appreciated.

Best Regards to all PIC enthusiasts.
