    The temperature correction is for when you measure the battery acid in the hydrometer, warm electrolyte is less dense than cold electrolyte. You use the chart to adjust the temp reading from what the floating element indicates.
    Will do. Thanks Mike.

    Bala, I think you asked me 2 times if I did temp correction and each time I answered you 'yes', but here you are asking again. "If temp correction is done correctly you can read SOC using SG at any time" is not correct based on this experience of mine.

      There is temp comPensation the Charger settings , this adjusts the charging voltage, lower when hot, higher when cold
      To read battery SoC, you need several idle hours for the battery to "settle"

      When measuring SG, you use a temp Correction table to adjust the SG the float reads. done correctly, you can read SG at any time, as long as your sample fluid has no bubbles in it.
