Causas comunes

  • A significant and unexpected change or instability in the battery's internal resistance during the RI charge measurement.
  • Malfunction in the charger's dedicated RI measurement circuit or its associated sensors.
  • The battery condition is not suitable for RI charging, or the battery itself is severely degraded.
