Regeneration
Regeneration means a cell is charged by pulse current regenerated during application. The regenerated voltage should be strictly regulated at all SOC and Cell Temperature. The magnitude and duration of pulse charging current should be strictly regulated according to the SOC and Cell Temperature listed on the table below. Regeneration charging of the cell outside this allowable condition may cause permanent internal damage to the Product and shall render DLG's warranties under the Contract inapplicable, thereby releasing DLG from any liability in connection therewnn.
