Hi freinds, I need to interface Li-Ion battery but some confusion with it. In Q2406B ther are total 4 pins availabele. one is for baterry temperature and rest may be for charging. But i saw in Nokia BL-5C battery there are only 3 pins. my question is how to interface it. is any program code is necessary for charging this battery or module will charge it automatically. ---

Therefore, if you’re in any doubt, don’t do it! > [@](#): > > But i saw in Nokia BL-5C battery there are only 3 pins. > my question is how to interface it. Your first step, obviously, must be to obtain the full and detailed specifications for this battery. You need to know exactly what those 3 pins do! ---

The thing is that there is no adl\_function to control the charging procedure, so it has to be done through AT commands. (Someone to affirm that,please). My question is the following: to which point does the WAVECOM module control its own charging procedure and to which point should the programmer interfere in this procedure? Thanks very much! ---

> [@tatiana](#): > > so it has to be done through AT commands. (Someone to affirm that,please). Yes, I’m afraid so - another of the many things that isn’t provided as a proper ADL API. 😠 > [@](#): > > to which point does the WAVECOM module control its own charging procedure As ever, you need to read the Datasheet (aka “Product Technical Specification” or “PTS”) for details! There is also an Application Note available ---

I guess q2406b just cannot charge Li-Ion batteries. AFAIR this feature was implemented since q2686. ---

> [@awneil](#): > > As ever, you need to read the Datasheet (aka “Product Technical Specification” or “PTS”) for details! > > There is also an Application Note available Of course I always consult the datasheets before asking a question. But the thing is that after giving the Q2686 the battery’s specification, is it necessary to check constantly the battery level and manually start and stop the charging procedure? And by the way which Application note you mean? Thanks in advance ---
