Answer to: Replaced battery but won't chargeHi Here's what I found... The exact same thing happened to me. The problem is with the new battery. If a lithium battery sits on the shelf for too long and it totally drains all of it's charge, it will be impossible to charge it up again using normal means. My advice is to call your battery supplier and get them to replace the battery with one that they have actually tested. After 3 tries I finally got a battery that worked. Hope this helps!!
Answer to: Replaced battery but won't chargeThis is a problem with ALL Lithium ion batteries... if they have sat on the shelf too long and become completely discharged, it will be very difficult to put a charge on it. Lithium ion batteries should not be completely discharged. I have the same problem now with my iphone 4s - replaced the battery and apple logo is flashing. Tried to restore the iphone but I get an error 21 in iTunes. The problem is during restart of the phone during the restore process - because the battery is completely discharged, the phone shuts off momentarily instead of restarting. That is why itunes fails on the restore process. Don't fall for the $9 iphone battery trick - the old saying "you get what you pay for"...
