BQ35100: Sudden SOH Drop to 0%

Part Number:BQ35100

Hi Team,

My customer is evaluating the BQ35100EVM with 4S Duracell CR17345 batteries (ChemID 0703), but are having issues where SOH suddenly drops from close to 100% to 0%. I suspected a wrong terminate voltage, but it is well below their battery voltage. They are running in SOH mode following the slua904 guide. Any ideas what could be causing this? Please see bqStudio screenshots below:

Thanks,

Antonio
