Recently, a blogger in Guangzhou posted that he bought a 10,000 mAh power bank 6 years ago, and now he sees that the tail of the power bank is a little bulging, "Do you want to change it after six years?" Related topics have sparked heated discussions.
Some netizens reminded: "The old advice is thrown to a special place, this power bank looks like it's going to be **", "The power bank should be replaced, and the power bank battery also has a service life." Some netizens are worried: "The power bank I used has not been bulging for ten years, but now the battery is not easy to use" "The same power bank is also deformed and cracked, and it can still be used, but I am worried." Some netizens analyzed: "It depends on the number of the charging treasure recycling logo, and there will be problems if the charging treasure exceeds this number." The reporter learned that the above-mentioned poster blogger has replaced the bulging power bank.
The circle is marked by the 5-year recyclable battery on the power bank.
The reporter saw from the above online post that the blogger said: "I bought it 6 years ago when I was in middle school, and now I am a senior, and I have seen a little bulge at the end of the charging treasure in the past two years, and then the charging is not very effective, sometimes I can charge it myself, and sometimes I have to press it to charge." ”
The reporter consulted the domestic first-line brand power bank manufacturer as a consumer, and the relevant technical personnel responded: "On the side of the brand power bank, there is a recyclable logo, and the number in the middle represents the recyclable life of the battery in the power bank." If the number is 5, it means that the rechargeable battery has a recyclable life of 5 years. If a rechargeable battery is a consumable, the battery may malfunction if it exceeds its recyclable life during frequent use. In addition, there are many reasons for the bulging of the power bank, one is the aging of the battery itself, and the enriched gas accumulates to a certain extent, and the shell is lifted. The second is improper charging, which may be an inferior charging head, etc., which causes the temperature of the power bank to rise and the battery to expand. The third is the quality of the battery itself. ”
Regarding the situation reflected by netizens, the staff finally analyzed: "The power bank has been used for 6 years has exceeded the battery recyclable life of 5 years, and it is recommended to replace the new power bank." In addition, from the point of view, the power bank has been bulging, pay attention not to touch it with sharp objects to avoid accidents, and should be put to a special battery ** point. Generally, the power bank produced by regular manufacturers has a 12-month warranty period, and if it is overwarranted, it will not provide free warranty. ”
