    REREGISTRATION HISTORY 
    As per the SAQA Board decision/s at that time, this unit standard was Reregistered in 2012; 2015. 

    UNIT STANDARD NOTES 
    Definition of terms within this Unit Standard:

    1. Charge cycle: In a wet cell battery the charge cycle refers to the three (3) stages
  • Stage 1 - initial stage
  • Stage 2 - gassing stage
  • Stage 3 - auto-equalise stage

    The full charge cycle refers to both the wet cell battery and the dry cell battery. Interrupting this cycle can dramatically reduce the service life of the battery.

    2. De-ionised water: Refers to water from which all mineral traces have been removed.

    3. Electrolyte: Refers to the mixture of sulphuric acid and de-ionised water in a wet cell battery.

    4. Hydrometer: Refers to the instrument used to measure the specific gravity of the electrolyte.

    5. Operating instruction: Refers to the manufacturer`s operating instruction or an extract there of.

    6. Positive pole: Is colour-coded red and marked with a plus (+) sign. (The negative pole is colour-coded blue and marked with a minus (-) sign.)

    7. Plates in the battery: Refers to the zinc plates that must be covered by
    the electrolyte after topping up the battery.

    8. Memory effect: Refers to the reduced performance in a dry cell battery caused by discharging the battery by less than 80% on a regular basis. (Similar to the effect when not fully discharging a cell phone battery).

    9. Specific gravity: If the specific gravity reading drops below one point one (1.1) the performance and service life of the battery will be dramatically reduced.

    10. Ventilated area: Refers to an area with sufficient air flow to disperse the gasses given off when charging a wet cell battery. The hydrogen given off during the gassing stage (stage 2) of the charging cycle is flammable and a safety risk.

    This information shows the current accreditations (i.e. those not past their accreditation end dates), and is the most complete record available to SAQA as of today. Some Primary or Delegated Quality Assurance Functionaries have a lag in their recording systems for provider accreditation, in turn leading to a lag in notifying SAQA of all the providers that they have accredited to offer qualifications and unit standards, as well as any extensions to accreditation end dates. The relevant Primary or Delegated Quality Assurance Functionary should be notified if a record appears to be missing from here.
