LR6 alkaline battery

　　What are the technical factors that affect the quality and performance of LR6 alkaline battery?

　　What are the technical factors that affect the quality and performance of LR6 alkaline battery? There are many factors that affect battery quality and performance. Even if the UPS uses the same battery technology, the battery life of UPS from different manufacturers is very different. This is very important to users because the cost of replacing batteries is high, and battery failure will reduce the system The reliability is a worrying thing. The following editor will take you to learn more about the technical factors that affect the quality and performance of LR6 alkaline battery.

　　LR6 alkaline battery are sealed lead-acid rechargeable batteries with ordinary electrolyte fixed in colloid, making the battery maintenance-free, thus saving the cost of maintenance, water replenishment and inspection, and no longer requiring expensive separate batteries equipped with special equipment. Battery room.

　　Although maintenance-free LR6 alkaline battery do not require manual maintenance during use, there are still certain requirements for use. Improper use will affect the service life of the battery.

　　1. Technical factors affecting UPS battery quality

　　1. Rated capacity is one of the important indicators for testing the quality of LR6 alkaline battery. my country uses the 20h discharge rate rated capacity as the rated capacity of lead-acid batteries for starting. The battery capacity indicates the power supply capacity of the battery. The larger the battery capacity, the more electrical energy it can provide and the greater the power supply capacity; conversely, the smaller the battery capacity, the smaller the power supply capacity.

　　2. Batteries with unqualified safety performance indicators are unacceptable. The biggest impact is explosion and leakage. The occurrence of explosion and leakage is mainly related to the internal pressure, structure, process design of the battery and incorrect operations that should be prohibited.

　　3. Acid amount and formation process: It is divided into two types: battery formation and tank formation. Battery formation can quantitatively inject acid and record the entire process data of each battery cell formation, and can accurately judge the comprehensive production quality status of each factory UPS battery, but Ian is longer during formation. Groove formation is for plate formation. Ian is shorter during formation, and plate formation is more complete, but it does not affect the quality of UPS battery assembly. It can be judged by recording the formation process data.

　　4. Battery composition: The battery is composed of positive plate, negative plate, AGM separator, positive and negative bus bars, electrolyte, safety valve, cover and shell. Among them, the thickness of the positive grid, alloy composition, uniformity of AGM separator thickness, bus bar alloy , electrolyte volume, safety valve opening and closing pressure, shell cover material, battery production process, etc. have an important impact on battery life and capacity uniformity.

　　2. Technical factors affecting UPS battery performance

　　(1) Since the current charging mechanism of the domestic DC system is not very perfect, there is voltage drift in practice. The UPS battery is in a floating state for a long time. If the floating voltage deviates from the normal range, it will cause overcharging or overcharging of the battery. Undercharging, long-term overcharging or undercharging has a great impact on the performance of the battery.

　　(2) Thermal runaway means that when the battery is charged at constant voltage, the charging current and battery temperature have a cumulative enhancement effect, and gradually damage the battery. Judging from the current investigation of battery usage, thermal runaway is one of the main reasons for battery failure. The direct consequences of thermal runaway are battery casing bulging, air leakage, battery capacity reduction, and in severe cases, plate deformation, and final failure. .

　　(3) Temperature has a great influence on the natural aging process of batteries. For every 5 degrees Celsius temperature increase, battery life decreases by 10%. Therefore, the UPS design should keep the battery as warm as possible. All online and backup/online hybrid types UPS generates more heat when running than backup or online interactive UPS, which is also an important reason why the battery replacement cycle of backup or online interactive UPS is relatively long.

　　(4) The operating humidity of the battery should be between 5% and 95%. If the ambient humidity is too high, condensation will form on the surface of the battery, which is prone to short circuits. If the PF environment humidity is too low, it is easy to generate static electricity. Excessive dust can also easily short-circuit the lead-acid battery and cause the safety valve to become clogged and ineffective.

　　With the continuous development of science and technology, the performance of LR6 alkaline battery is getting better and better, the average working time between failures is getting longer and longer, and the reliability of the whole machine is getting higher and higher. It has become particularly important to maintain the consumable batteries in UPS.
