18650 lithium battery, with battery protection plate and without protection plate, the differences are as follows: 1. The height of the battery core without plate is 65mm, and the height of the battery core with plate is from 69 to 71 mm. 2. Discharge to 2.0V. If the battery does not discharge when it reaches 2.4V, it means there is a protection board. 3. Touch the positive and negative steps. If there is no response from the battery after 10 seconds, it means it has a protective plate. If the battery is hot, it means there is no protection plate. Note: During the third test, non-professionals should not do this experiment, as it may cause a powerful explosion and cause irreparable personal harm, especially when encountering inferior batteries.
Is there any difference between the disassembled 18650 lithium battery and the original one?
Lithium battery dismantling modules are usually recovered from second-hand cell phones or secondary recycling at scrap metal stations. Generally, in order to avoid increased costs, unscrupulous traders will refurbish in this way. .
Since disassembled batteries are also called secondary use batteries, disassembled batteries before 2019 basically refer to disassembled 18650 cylindrical batteries, which are made from ready-to-use products. use or from After testing, the power battery is removed and refurbished for use. Most batteries dismantled after 2019 refer to batteries reused by echelon. They are basically separated from the battery modules that have been tested or the battery modules that have been removed from new energy vehicles. in the battery industrylithium, let's call it directly and roughly battery disassembly.
Would you be surprised when you see this disassembled lithium battery refurbishment method? In fact, if the disassembled power battery removed from a new energy vehicle is used in some small low-speed vehicles and small electric vehicles, electric sweepers, energy storage systems, etc. all have certain advantages.
After all, the cost of using the new original batteries has been reduced. This model also gives some battery companies a margin of survival, because some products are indeed suitable for this solution, but the old ones are old. , there will be some gap in terms of security and performance.
Disassembled 18650 batteries are usually disassembled from discarded laptop or power tool batteries. The capacity is insufficient, thenumber of times rechargeable and dischargeable is reduced, the discharge current is reduced and it is. not profitable and practical. The original battery is a great concept as long as it is produced by the original factory, whether it is new or old, whether it has been used or not, it can be called original. In Xbao, if it is marked as new and original, it is a new battery. Otherwise, there isn't much difference between the two batteries themselves. The biggest difference should be the heart of the store owner.
