Hi people,
I need help to project my gas gauge.
My device have a li-ion battery, 3.6V 800mAh, it uses MCP73831 and I have no problem to charge the battery. But I need inform with precision to operator that the battery have more 30 minutes of life.
For this I want use LTC4150. But I´m not understanding as the part knows the total charge of my battery (800mAh).
For exemplo, through Coulomb Count the LTC informe to me the current that into and out, but how i can use this to calculate my battery life in first use of the device.
Laptops use gas gauge ?
Tnx very much!
