BQ27426: Choice for TS NTC resistor

Part Number: BQ27426

Dear,

Here we have a wristband project using BQ27426, as for the choice of external 10kohm NTC resistor. Do we have a criterion?

In the datasheet, we only see the thermistor "Semitec 103AT", but it is not a completed part number, so we are not clear about Beta required.

Here we have two below 10kohm NTC to be decided, which is recommended? Thanks

(1) R25C=10kohm+-1%, Beta(25/50) value = 3380k+-1%;

(2) R25C=10kohm+-1%, Beta(25/85) value = 3435+-1%. 

We really want to know how to choose the thermistor. Thanks.
