Coconut Battery app discovers a gem ;)

Your saying that they are going round the all the trash dumps or wherever to collect or salvage old batteries to reuse some component? c'mon.... that makes no sense whatsoever, let alone times consuming, man power etc..... you would spend days finding a couple of battery then taking it apart to take a component and then sell it again for $40.... It don't explain how 1/3 same order displayed a 10 year old date.... More likely they bought some old stock components, certainly not salvaging from dumps or recycle centers..... I would like to see a source for that. No big deal anyway, just a strange occurrence. I will ask the supplier why the date is 10 years old.... no doubt they will have to ask tgeir supplier and a reply is unlikely.

@livfe - Have you visited mainland China? I have and visited some of the small family based manufacturing in Tsuen China just north of Hong Kong. Many batteries are remanufactured from these makers. During the day they are at the big corporate factories, then dumpster diving salvaging what they can. These folks have a market place to barter parts. Even here in the states we have market places doing the same! COVID didn’t stop this effort, only the big factories.

@danj I lived in China for 7 years near to Guangzhou (Shunde) & I have seen 'Quite a few' interesting things out there.... not much surprises me anymore ;) But, this 'answer does' LOL as if the dumpster was full of old mac batteries ... anyway....I got a box of old batterihere, I should do the same, what parts can I salvage, as 'every little helps' as the say :)

@livfe - Did you ever visit the market area where all of the small shops sell their goods? I was amazed on what was collected. I didn’t ask where or how but they clearly hover up anything to reuse that has value.

@danj Yes I have seen that in Shenzhen, I visited a few factories as my friends I made there were all manufacturing stuff, and have seen some of the huge factories there that make electronics, They are so big I really doubt buying a few old used parts would benefit them and be worth their time and effort.... from what I have seen there are around 8-10 battery makers there in Dongyan and Shenzhen and they are massive plants.
