Can Maintenance-Free Batteries Be Refilled with Repair Solution?
1 Answers
Maintenance-free batteries can be refilled with repair solution. Sealed maintenance-free batteries adopt the latest fully sealed structure design from the 1990s and modern production processes, giving them outstanding performance characteristics such as high efficiency, long lifespan, pollution-free operation, maintenance-free convenience, and safety reliability. Below are relevant details: 1. Principle: During charging, electrical energy is converted into chemical energy, while during discharging, chemical energy is converted back into electrical energy. When discharging, metallic lead acts as the negative electrode, undergoing oxidation to form lead sulfate. Lead dioxide serves as the positive electrode, undergoing reduction to also form lead sulfate. When charging with direct current, the two electrodes generate lead and lead dioxide respectively. After disconnecting the power source, the battery returns to its pre-discharge state, forming an internally balanced chemical cell. Lead-acid batteries are rechargeable and dischargeable cells, also known as secondary batteries. 2. Advantages of Maintenance-Free Batteries: Due to their structural advantages, maintenance-free batteries consume very little electrolyte and generally do not require distilled water replenishment during their service life. They also feature shock resistance, high-temperature tolerance, compact size, and minimal self-discharge, with a typical lifespan twice that of conventional batteries.
