Distilled water or domestic purified water should be added. Because the battery is working, sulfuric acid is not consumed, only water is consumed, so only water is compensated.
The reaction formula is: Pb+PbO2+ 2H2SO4=2PbSO4 ?+ 2H2O. Therefore, during the discharge process, the sulfuric acid becomes diluted and its density decreases. During charging, sulfuric acid is generated again, but during use, water will increase and decrease.
Detailed information
Storage battery is a device that directly converts chemical energy into electrical energy. This is a battery designed to be rechargeable. reversible chemical reactions, generally referring to lead-acid batteries, which are a type of battery and secondary batteries.
How it works: When charging, it uses external electrical energy to regenerate internal active materials, stocke electrical energy as chemical energy and converts the chemical energy back into electrical energy when it needs to be discharged, for example. because the commonly used mobile phone batteries in life are waiting.
It uses a lead-based grid filled with sponge lead (also called a grid) as the negative electrode, and a lead-based grid filled with lead dioxide as the positive electrode, and uses a density of 1 .26 to 1.33 g/mlg/ml. dilute sulfuric acid as an electrolyte.
When the battery discharges, the lead metal is the negative electrode and an oxidation reaction occurs to generate lead sulfate; lead dioxide is the positive electrode, and a reduction reaction occurs to generate lead sulfate. When the battery is charged with direct current, elemental lead and lead dioxide are produced at the two poles respectively. Once the power sourceremoved, it returns to its pre-discharge state, forming a chemical battery.
Lead-acid batteries can be charged and discharged repeatedly. The voltage of their cells is 2 V. A battery is a battery composed of one or more cells, called the most common battery. and others are 2V, 4V, 8V, 24V batteries. For example, the battery used in a car (commonly called a battery) is a 12V battery consisting of six lead-acid batteries connected in series.
For traditional dry-charged lead-acid batteries (such as automobile dry-charged batteries, motorcycle dry-charged batteries, etc.), distilled water should be added after a period of use to preserve the diluted sulfur. acidic electrolyte at a density of approximately 1.28g/ml; For maintenance-free batteries, there is no need to add distilled water until the end of their life.
