| Term | Definition |
|---|---|
| DEEP DISCHARGE | The discharge of a battery until the voltage under load drops below the 50% of the batteries nominal capacity. |
| DENSITY | The weight of a given volume of electrolyte at a specified temperature. The customary units are kg/m3. |
| DEPOLARISATION | A reduction in the polarisation of an electrode. |
| DEPTH OF DISCHARGE | The Ampere-hours (or Watt-hours) removed from a fully charged battery, expressed as a percentage of its rated capacity at the applicable discharge rate. |
| DIRECT CURRENT (DC) | The flow of electric charge in only one direction. |
| DISCHARGE | The conversion of chemical energy into electrical energy within a cell. Sometimes additional modifiers are used to describe how much of the cell’s capacity was removed during the discharge, for example, SHALLOW DISCHARGE or DEEP DISCHARGE. Normally, a deep discharge would imply that at least 80% of the cell’s rated capacity was removed during the discharge. |
| DISCHARGE RATE | The rate in Amperes (or Watts), at which current (or power) is delivered by the battery. |
| DRY CHARGED CELL | A cell which has been assembled with its plates dry, and in a charged state, ready to be activated by the addition of electrolyte. This is normally done for ease of shipping or storage, or both. |
| DYNAMIC ELECTRICITY | A flow of electric charge. |
