Query: Bad Batteries! BEWARE!

The batteries were defective and OLD! The date code on the UPC bar code was 2006! I can't believe Amazon would sell these and try to pass them off as legitimate! NEVER buy rechargeable batteries through Amazon, as they obviously buy cheap old stock that is outdated.They were not an 8 pack either - it was 2 4 packs, one was good (2010) and one was bad (2006).
