The correct answer is D. None of the above.
A dead storage battery cannot be revived by adding distilled water, adding so-called battery restorer, or a dose of H2SO4. Adding distilled water will not provide the battery with the energy it needs to start working again. Adding so-called battery restorer may provide the battery with a temporary boost, but it will not solve the underlying problem. A dose of H2SO4 will only damage the battery further.
The only way to revive a dead storage battery is to replace the dead cells. This is a job that should be done by a qualified technician.
Here is a brief explanation of each option:
- Option A: Adding distilled water. Distilled water is a type of water that has been purified to remove all impurities. It is often used in batteries to help keep the cells clean and free of corrosion. However, adding distilled water to a dead battery will not revive it. The battery needs a source of energy to start working again, and distilled water does not provide that.
- Option B: Adding so-called battery restorer. So-called battery restorers are products that are marketed as being able to revive dead batteries. However, there is no scientific evidence to support these claims. In fact, some battery restorers can actually damage the battery.
- Option C: A dose of H2SO4. H2SO4 is a type of acid that is often used in batteries. It helps to create a chemical reaction that produces electricity. However, adding H2SO4 to a dead battery will only damage the battery further. The battery needs a source of energy to start working again, and H2SO4 does not provide that.
If you have a dead storage battery, the best thing to do is to take it to a qualified technician. They will be able to diagnose the problem and replace the dead cells.
