Why do Nickel Hydride Batteries fail early?
Why do Nickel Hydride Batteries fail early? UPS battery failure and scrapping process. The design and production process of Nickel Hydride Batteries determine the inherent reliability of the battery pack, and the use and maintenance of UPS battery packs 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. The early scrapping of a large number of Nickel Hydride Batteries has caused a huge waste of resources, while increasing the company's operating costs. Improper handling of waste Nickel Hydride Batteries also causes environmental pollution.
Reasons for early failure of Nickel Hydride Batteries
1. Early failure of Nickel Hydride Batteries means that during the use of the battery pack, the performance of individual batteries deteriorates sharply, and the capacity is less than 80% of the rated value, and the fundamental reason for the early failure of Nickel Hydride Batteries is that the battery [】negative plate is out of contact with the electrolyte in the AGM separator.
2. The performance and life of Nickel Hydride Batteries depends on the materials used to manufacture the positive and negative plates, the industrial environment, the purity of the active substances, the use environment and maintenance, etc., which have a very important impact.
3. The early failure of individual Nickel Hydride Batteries in a group of Nickel Hydride Batteries is generally caused by individual accidental factors in the production process, such as tiny lead particles falling into the pole group when welding the pole group, poor control of acid addition, loading of unqualified parts, and unqualified raw materials.
UPS battery failure scrapping process
(1) Clean the top of all batteries;
(2) Sort the batteries by the same brand and model;
(3) Pick out those with damaged, corroded, or leaking appearance, and do not repair them;
(4) Arrange them in an even sequence to facilitate the connection of the positive and negative poles;
(5) Connect the batteries with connecting strips;
(6) Connect the charger to the positive and negative poles;
(7) Charge for one hour, test the UPS battery, and then discharge to check whether there is a short circuit or open circuit;
(8) When the repair conditions are met, connect the discharge system as required;
(9) Adjust the standard data of the discharge system to meet the standards of the battery group;
(10) Start discharging, and add deionized water and 10% regeneration agent in a ratio of 1:1 after the discharge point is completed;
(11) Charge for 16 hours and then discharge for a cycle.
Nickel Hydride Batteries will be in floating charge state for a long time, which will reduce the activity of chemical energy and electrical energy conversion, accelerate aging and shorten service life. Therefore, it is generally necessary to fully discharge the Nickel Hydride Batteries every 2-3 months, so that the Nickel Hydride Batteries can be discharged for a period of time. This can not only activate the Nickel Hydride Batteries, but also check whether the batteries are in normal condition. At the same time, the UPS should be charged in time and for a long time to prevent malfunctions caused by UPS battery exhaustion.
