1.	What is the value in volts of the negative terminal in the case of the cadmium test?(a) Not more than 0.2(b) more than 0.5(c) Not more than 1(d) More than 1.3I have been asked this question during an online interview.My doubt is from Battery Testing in section Storage Batteries of Automotive Engine Design
Answer» The CORRECT option is (a) Not more than 0.2 For explanation: In a cadmium test the CHEMICAL CONDITION of the POSITIVE and negative plates is determined. The reading with the negative battery terminal should not be more than 0.2 volts when the battery is being DISCHARGED at a normal rate. A higher reading in this case will indicate defects in negative plates.
