6 FAQs about [Lead-acid battery cadmium potential test]
Why is cadmium used in lead acid batteries?
In the design of Lead Acid batteries, cadmium is employed to identify the specific electrode that is causing the battery to underperform during the last stages of discharge. Occasionally, it is noticed that both the positive and negative electrodes contain an adequate amount of active material, but there is a lack of electrolyte.
What does cadmium mean in a battery?
It specifically indicates whether the failure of the battery is due to positive active material, negative active material, or electrolyte deficiency. In the design of Lead Acid batteries, cadmium is employed to identify the specific electrode that is causing the battery to underperform during the last stages of discharge.
How do you test a lead-antimony battery?
In the case of a lead-antimony battery, measure and record the specific gravity of 10% of the cells and float charging current. For chemistries other than lead-antimony and where float current is not used to monitor the state of charge, measure and record the specific gravity 10% or more of the battery cells.
How often should a lead-acid battery be tested?
IEEE 450-2002, “IEEE Recommended Practice for Maintenance, Testing and Replacement of Vented Lead-acid Batteries for Stationary Applications” describes the frequency and type of measurements that need to be taken to validate the condition of the battery. The frequency of tests ranges from monthly to annually.
What are the standards for battery testing?
There are a number of standards and company practices for battery testing. Usually they comprise inspections (observations, actions and measurements done under normal float condition) and capacity tests. Most well-known are the IEEE standards:
Why is cadmium a neutral electrode?
Cadmium serves as a neutral electrode to identify the cause of failure in a lead acid cell. It specifically indicates whether the failure of the battery is due to positive active material, negative active material, or electrolyte deficiency.
