I recently ordered two batteries for our cell phones.  I got them before the date stated (good job!).  We discovered that these batteries didn't hold a charge any longer than our 'old' batteries that we replaced.  I contactd customer service and told them my delema ...they were on it immediately, and shipped us 2 new batteries within a matter of days!  These ones are keeping their charge.  The price is right, and the Customer service is amazing!  Thanks!
