The specific gravity readings of a lead-acid cell taken twice after charging shows substantially lower value.
- You replace the cell
- You top up the cell with distilled water
- Cell is defective
Explanation
If a lead-acid cell still shows a substantially low specific gravity after charging and a repeat reading confirms it, the active material or plates are no longer accepting charge, indicating the cell is defective. Topping up with distilled water corrects only a low electrolyte level, not a low specific gravity, so the cell itself is at fault.
MridulDev asking:
is this question tricky or this question is acting devil, why can't "replacing the cell" be a right answer. but i consider both answer to be correct. if any one can lighten up then that would be wonderful.

Self correction: there's no such think such as replaceable lead acid cell.(study a/c lead acid battery in detail u'll know). Hence "cell is defective" has to be right answer in this case.

the cell will be defective easy as that you just have to asnwer the question on the exam not right an essay Mridul.
