Question 416Electricity & Electronics - QMED

The correct answer is A) The specific gravity of the electrolyte will be generally unaffected by the state of charge. This is because the specific gravity of the electrolyte in a nickel-cadmium battery is not significantly affected by the state of charge. The specific gravity remains relatively constant throughout the charging and discharging cycles, unlike lead-acid batteries where the specific gravity changes. The other options are incorrect: B) Extended trickle charging should be avoided - This is true, as extended trickle charging can cause overcharging and damage to the battery. C) Add distilled water just prior to charging to insure proper mixing - This is not necessary, as the electrolyte in a nickel-cadmium battery is already well-mixed. D) The charging rate should never allow gassing - This is not entirely correct, as a small amount of gassing is normal and expected during the charging process.
