　　UPS manufacturer explains 1.5v dry cell battery failure and scrapping process

　　UPS manufacturer explains the 1.5v dry cell battery failure and scrapping process. The design and production process of the battery determine the inherent reliability of the battery pack, and the use and maintenance of the battery pack are the basis for ensuring the reliability of the battery pack. Proper use and maintenance can extend its service life, otherwise its service life will be greatly shortened. However, a large number of batteries are scrapped in advance, resulting in a huge waste of resources and an increase in the company's operating costs. Improper disposal of used UPS batteries also causes environmental pollution. Next, let’s learn about the 1.5v dry cell battery failure and scrapping process.

　　1.5v dry cell battery failure and scrapping process

　　1. Clean the top of all batteries.

　　2. Classify batteries according to the same brand and model.

　　Low temperature lithium iron phosphate battery 3.2V 20A -20℃ charging, -40℃ 3C discharge capacity ≥70%

　　Charging temperature: -20~45℃ -Discharge temperature: -40~+55℃ -40℃ Support maximum discharge rate: 3C -40℃ 3C discharge capacity retention rate ≥70%

　　3. Pick out all the parts that are damaged, corroded, or leaking in appearance. These parts will not be repaired.

　　4. Arrange them in an even number sequence to facilitate the connection of the positive and negative poles.

　　5. Connect the battery with the connecting strip.

　　6. Connect the charger to the positive and negative terminals.

　　7. Charge for 1 hour, check the 1.5v dry cell battery and then discharge it to check whether there is a short circuit or open circuit.

　　Low temperature and high energy density 18650 3350mAh-40℃ 0.5C discharge capacity ≥60%

　　Charging temperature: 0~45℃ Discharge temperature: -40~+55℃ Specific energy: 240Wh/kg -40℃ Discharge capacity retention rate: 0.5C Discharge capacity ≥ 60%

　　8. When the repair conditions are met, connect the discharge system as required.

　　9. Adjust the standard data of the discharge system to make it comply with the standards of the battery group.

　　10. Start discharging and after discharging ends. Add deionized water and 10% regenerant according to the ratio of 1:1.

　　11. Charge for 16 hours and then discharge and cycle.

　　Reasons why UPS batteries fail and become scrapped when not used

　　1. The combination of active substances in lead-acid battery manufacturing materials is unreasonable;

　　2. The electrode plates did not meet the charging and discharging standards during chemical treatment; the electrode plates were stored in a poor storage environment or were stored for too long, the seals were damaged, and they were exposed to oxidation in the air for a long time, causing the active materials of the electrode plates to be aged;

　　3. Improper maintenance during use, a certain monomer is in a de-energized state for a long time, and after a reverse voltage occurs in the de-energized monomer during large current discharge, the battery is not maintained in time, resulting in irreversible vulcanization of the monomer and failure.

　　By improving the performance of lead-acid batteries, we ensure the stability and safety of batteries, extend their actual service life, and reduce solid waste pollution caused by scrapped lead-acid batteries; and reduce gas pollution caused by scrapped lead-acid batteries. At the same time, it increases the battery life, saves corporate investment, reduces operation and maintenance costs, reduces environmental pollution, and truly realizes the development of a circular economy in the industry.
