undercharged for a significant time, etc.), your battery’s tate of health could drop dramatically. Since this
will affect the reliability of SoC calculations, we recommend you to perform a Full Synchronization.
3. Charged and Discharged Voltage values
The default Charged Voltage value is set based on Nominal Voltage according to the table below. If you
change the Nominal Voltage setting for your battery, the Charged Voltage value will be set to default.
However, you may override the Charged Voltage value with your own setting; otherwise, or if the parameter
is set to UNKNOWN, the default value will be used.

4. Calculations reset
Both SoC and SoH values are set to 100%, and consumed Ah is set to 0 Ah in the following cases:
• you turn calculations ON with CALCS parameter or YD:CALCS command (see Section IX)
• you reset Device settings with CFGRESET parameter or YD:RESET command
• you change Capacity value in CAPACITY parameter or with YD: CAPACITY command
If you connect a battery to a Device whose SoC / SoH is set to 100%, or whose memory contains values
calculated for a different battery, the Device readings may not reflect the actual state of the battery.
The same may happen when you reconnect the Device to the same battery after a period during
