I use BQ34Z100-G1 with a 7Ah 12V lead acid battery (closed cell). I use 808 chemistry. After 9 charge-discharge cycles, the values are still off. Also the learned status does not change.
The flags seem to be allright. One error I can see is that the CHG flag is not removed on discharging. What is happening ?
