Making statements based on opinion; back them up with references or personal experience. i was going through some propriety schematics that i can't post, the battery used in the schematic is a li-ion battery of 3.8V/2.1Ah/ from samsung, which gives out three pins + - vf, i have seen batteries in my previous experience trying give a thermistor output which conveys the temperature value of battery, but what exactly is vf here, i came across some one calling it a forward voltage of diode which is used inside the battery, the vf from battery was going to an ADC in my design, some useful link i have found is here which speaks about internals of a nokia bl5c, as the design is of a smartphone itself i assume this battery would be similar to mine, in short i know this is been used for battery detection but i want a clear cut idea on how is this helping. Li-Ion batteries instead wear out over time due to age and use. If you want to test if it is charged with a multimeter then it should read at 4.8V or a little higher from what I can tell. an extremely corrosive solvent. As you might guess, different metals have different attractions between Easy solution think which tools you want, decide which tools you actually need and then do a bit of research on what is available on the market and you should come up with a half decent idea on which manufacturer is most likely to cover all your needs.
