Interesting that you would compare an amazon vendor to aliexpress. I've never had an issue with amazon like the ones I'm hearing about aliexpress, have you? But I guess I'll see.
I don't use AliExpress but my friend does (and he is who ordered this battery for me). I don't have a lot of comparison experience. But it is absolutely 100% true that there are a LOT of direct-from-china vendors on Amazon, and Ebay too. And I am guessing they are a lot of the same people who are also on AliExpress. I would tend to trust Amazon a LOT more.
But I am basing what I said on what I saw of the listing you provided (B00PANRXFC)... comparing that to the Ali listings. Same non descript type of listing. No mention of "used" or "new". Direct Chinese vendor. And a 10% negative review rate on the vendor is very high. Look at these reviews on products that "ZTHY Tech" sells:
"Battery was dead. No charge at all. Not pleased."
"Took almost two months to get battery. First one was defective, just received the second one after a couple requests for replacement. Will not do buisness with you again."
"Bad battery. Only charging 50%.not original."
"I ordered a NEW battery, and received a previously used battery in a box marked "new." The battery they sent was obviously used, as it had fingerprints and old tape on it. Very disappointing discovery - returned the item."
"your "new" battery ha now been installed in my laptop for a bit over 2 weeks. first 2 weeks, i had 4+ hours of battery life with your new battery. no battery no longer charges. i have less then 10 minutes of battery life. was this a new battery that you sold me? what can we do? thx"
"Item was used and in poor condition not new as described."
"Seller shipped used battery as new."
"This is the 2nd battery that came from them that is clearly NOT a new product. DO NOT BUY FROM THEM. My attempts to contact them after the first battery failed - they did not bother to respond at all. Get your battery from some other place!"
"This is supposed to be a NEW item, but it was clearly a used item - and it does not work!! I feel scammed!!"
"Does not charge to the fullness"
"I wouldn't deal with this vendor again"
"Terrible battery life. Barely reaching 2 hours before I need to plug in.[...]Would not buy from again, and trying for a refund."
"this battery vary bad i don't like"
"Received a Defective item only be able to charge at most 27%"
