Can Medical Distilled Water Be Added to a Battery?
1 Answers
Medical distilled water can be added to a battery. The main reason is that distilled water contains almost no metal ions and has very high resistance. Therefore, adding it to the battery will not cause self-discharge, so it can be added in small proportions. Here are the details: 1. Do not exceed the standard level of the battery solution when adding distilled water: Excessive solution can affect the battery's lifespan. After a lead-acid battery has been used for some time, the lead plates and dilute sulfuric acid continuously undergo chemical reactions, during which some gas evaporates, gradually reducing the solution volume and increasing its concentration. This changes the concentration conditions required for normal battery operation. Adding a small amount of distilled water at this time can alleviate the harm of excessively high battery liquid concentration and bring the battery solution back within the normal working range. 2. When the battery is short of water: Only distilled water or purified water should be added. This is because the battery's specific gravity is already adjusted when it leaves the factory. If electrolyte is added on one's own, it will naturally increase the specific gravity value, not only directly affecting the battery's normal operation but also accelerating the aging of the battery plates.
