    5. UNIT OPERATION Understanding the Battery Charging Current Setting: The battery charging current rating is based on the battery size. When charging GEL, AGM and Flooded batteries, each battery bank should meet the minimum Ah rating as shown on below chart. If a smaller size battery bank is used, set the current rating to a lower value to match with the battery bank size.
  • Page 14 Mode 2 Charging: The Two-Stage mode 2 charging is similar to the Three-Stage charging except that there is no Float stage after the Absorption stage. The charger will terminate the battery charging after Absorption stage. The charger will automatically restart the full charging cycle if it senses any one of the battery banks is discharged to lower than 12.5V for the 12V model, 25.0V for the 24V model, or after seven days since the last Absorption stage to refresh the battery banks.
