Hi...

My customer have some problem about battery chemistry of BQ27621-G1.

The battery chemistry of my customer is CR2/3V or CR123A/3V as follows.

1. Is it possible of battery fuel gauge through BQ27621-G1 to use this CR123A battery?

If it isn't possible, what is the proper fuel gauge solution of this case?

I think that this CR123A battery can not apply to BQ27621-G1.

Please give me a good solution and advice.

Thanks.

I have same request.

The bq27621 won't work with a primary cell like the CR123A. This gauge is intended for rechargeable cells.

The bq35100 (preview part) may work with this cell. www.ti.com/.../BQ35100
