No NO, this is not another battery thread, I promise ! This thread is for the 3500mah Battery, with extended Back cover from eBay. there are a few threads containing information on the 2600mah batteries, and 3000mah batteries, but this is different These are 3500MAH batteries. I ordered mine a few days ago, has anyone received this actual battery - doesnt matter if it's from the same seller or not, just as long as it's a 3500mah battery with HongKong Level/Large caseback (no hump). Just wanted to know if anyone is using it, and how long have you had it, and if quality has degraded over time. Here is what i wrote in the EVO thread, but i think we need to have a 3500mah discussion in the D-Inc forum. the Seido/Verizon/Ebay batteries are all made in the same place. There are a few differences, for one. Verizon "claims" to quality check each and every battery that is shipped and sends anything back that is below the average MAH for the specific battery. I also heard that Seidio does QC, but not very often and not very well. I read an article about china/hong-kong factories and read that all of these batteries are LITERALLY made from the same assembly line, and when they get to their rightful owners (verizon/seidio/htc), they put their stamp on it after it has gone through quality control. The reason some people get lemons is because there is no quality control for the ebay ones .They just go into the warehouse, grab one of the 10,000 batteries lying around send send it to you. It costs them 50 cents to make the battery, and verizon/sprint and others exploit the hell out of us because they know the consumer will always take something that is brand name, or considered OEM over anything with no-name. What most consumers don't realize is that they are the same battery! It's all about luck since there is no QC when ordering on ebay, hopefully the seller will respect the buyer and replace the battery if it's bad .
