How long is the service life of Panasonic battery?

About Panasonic battery, many people are curious about its service life, so let's let Xiaobian introduce it in detail today!
Due to the increase of the thickness of the positive grid, the service life of the battery can reach 10-15 years according to the calculation of the corrosion rate of the grid by using Pb-Ca-Sn-Al four element corrosion-resistant alloy. However, from the results of battery use, water loss rate has become the most critical factor affecting the service life of sealed battery.
Panasonic battery answer:
1. There are many factors affecting the service life of Shenyang Panasonic battery, including the factors of battery design and manufacturing, as well as the factors of user use and maintenance conditions. In terms of the former, the corrosion resistance of the positive grid and the water loss rate of the battery are the two most important factors. Due to the increase of the thickness of the positive grid, the service life of the battery can reach 10-15 years according to the calculation of the corrosion rate of the grid by using Pb-Ca-Sn-Al four element corrosion-resistant alloy. However, from the results of battery use, water loss rate has become the most critical factor affecting the service life of sealed battery.
2. For AGM sealed lead-acid battery, the battery capacity is very sensitive to the amount of electrolyte due to the lean solution design. The battery loses 10% of water, the capacity will be reduced by 20%; 25% of water will be lost, and the battery life will end. However, the gel sealed lead-acid battery adopts the liquid rich design, the density of electrolyte is lower than AGM sealed lead-acid battery, which reduces the corrosion rate of grid alloy; the amount of electrolyte is also 15% - 20% more than AGM sealed lead-acid battery, which is less sensitive to water loss. All these measures are beneficial to prolong the battery life.
According to the data provided by Panasonic battery, the water content of colloidal electrolyte is enough to make the battery run for 12-14 years. In the first year when the battery was put into operation, the water loss was 4% - 5%, and then decreased year by year. After four years, the total water loss was only 2%. The capacity of op2v sealed cell is still 90% after 10 years of floating charge operation at 2.27v/cell. From the reflection of some domestic posts and telecommunications departments, Panasonic battery has a high price, but its service life is longer than AGM sealed lead battery.
