Planning to use 3.7V non-Rechargable battery with npm2100 with an additional diode?

I am planning to use 3.7V non Rechargable Battery with Diode and Reverse Protection circuit with npm2100, Would like to build a Fuel Guage model for this as this is not available. As per Data sheet. voltage max support is 3.4V and absolute max iw 5.0V.  Let me know if this is an workable solution with npm2100.  Voltage Drop from Diode and Reverse protection circuit will be below 3.4v as per specs.

Hello Ramakrishna,

Currently only the following battery models / chemistries are supported with nPM2100 fuel gauge solution.

AA Alkaline (single or two in series)
AAA Alkaline (single or two in series)
Alkaline coin cells
LiMnO2 based coin cells

Also note that nPM2100 voltage based Fuel gauge solution cannot be used with battery voltages above 3.2V since ADC is limited to measure VBAT below 3.2V 

But if the other ratings are within the rated operating conditions of nPM2100 can be used without using fuel gauge. 

Best regards,
