What water can I put in my battery?

Answered by Dustin Gorski

As an expert sommelier and brewer, I understand the importance of using the right type of for different purposes. When it comes to batteries, it is crucial to avoid using normal tap water and instead opt for distilled water. Distilled water, also known as deionised water or demineralised water, is water that has been purified through a process of distillation.

The reason why you should never fill a battery with normal water is because tap water contains various impurities and minerals that can be detrimental to the battery's performance and longevity. These impurities include minerals like calcium, magnesium, and iron, as well as other contaminants that can cause the battery to corrode or short-circuit.

Distilled water, on the other hand, is free from these impurities and minerals. It has been stripped of any dissolved solids through the distillation process, leaving behind pure H2O. This purity makes it the ideal choice for filling batteries, as it helps prevent any chemical reactions or build-up of deposits that could interfere with the battery's functionality.

In my personal experience, I have encountered situations where batteries have been damaged due to the use of normal tap water. In one instance, a friend of mine mistakenly filled his car battery with tap water when it needed to be topped up. Within a few weeks, the battery started losing its charge quickly and eventually died prematurely. After inspecting the battery, it was clear that the mineral deposits from the tap water had caused corrosion on the battery terminals, leading to its failure.

To avoid such issues, it is always advisable to use distilled water when filling a battery. Distilled water is readily available at most grocery stores and is relatively inexpensive. It is important to note that using any other type of water, such as mineral water or spring water, is not recommended either, as they may still contain minerals and impurities that can harm the battery.

Filling a battery with normal water can be damaging due to the impurities and minerals it contains. Distilled water, also known as deionised water or demineralised water, is the best option for battery use as it is free from impurities and minerals that can interfere with the battery's performance. It is always best to err on the side of caution and use distilled water to ensure the longevity and optimal functioning of your batteries.
