Project acceptance stage maintenance: 1, test voltage, conductivity balance (float three months after the test average as a benchmark conductivity value) 2, right conditions should be full capacity discharge test
Float charging operation stage maintenance: 1, monthly test conductivity, voltage, and horizontally compared to the individual conductivity differences, longitudinal and benchmark conductivity values. Conductivity difference, vertical and benchmark conductivity value comparison to see the amount of change 2, when there is a warning battery, a full-capacity discharge test should be carried out 3, when there are individual backward batteries, that is, the replacement of backward monomer 4, a full-capacity discharge test every year
End-of-life replacement stage of maintenance: when there are a large number of backward monomer, that is, the replacement of the whole group of batteries for scrapping.
