What are the identification methods for refurbished UPS power lead-acid batteries?

The identification method of refurbished UPS power lead-acid batteries At present, there are two refurbished batteries on the market. Take a set of 4 batteries as an example. The practice of regular manufacturers is to replace the old UPS power battery with a new battery if one is broken. Some small repair shops reassemble and refurbish old batteries that are recycled at low prices, and replace them with new packaging for new batteries for sale. The quality of the former refurbished battery is acceptable; the quality of the latter is not guaranteed at all. Although refurbished UPS power lead-acid batteries are rare in the market now, if you are not buying them in regular stores, especially from street vendors, you may be able to buy refurbished lead-acid batteries. Therefore, it is necessary to master some screening methods. 1. Distinguish from the appearance. Look at the printing on the product. Refurbished UPS power batteries are generally printed very rough and irregular. Another is the processing date above. The refurbished batteries are not printed very clearly. Observe whether there is any obvious damage to the battery casing, especially the gap between the battery slot and the cover. 2. Judging from the price. If the price is significantly lower than the market price, it may be refurbished. After all, you get what you pay for! 3. Many refurbished UPS power lead-acid batteries will be printed with the words maintenance, turnover, spare, after-sales, etc., so you need to observe them when you buy them. 4. Observe whether the pole glue on the edge of the pole is evenly spread and whether the pole has large corrosion.
