My old Motorola Razr cell phone had been washed accidentially in a load of laundry.  When I retreived it, it was dead and apparently it had a shorted and unusuable battery.  I put the phone away and forgot about it until just recently when my new (Replacement for the washed one) died.  I needed a backup until I could receive another phone so I took the old Razr out of the closet and put the battery out of the replacement phone, that was not working, and put it into the old Razr.  Lo and behold, the old phone worked great with a new battery and 2 years of drying out.  Only problem was that the original battery did not hold a charge because of water damage.  I found a battery locally at Walmart and was astounded that the price for the battery was $28.  I began looking online and came upon my old friend, Amazon.  I found an EXACT replacement, manufactured by Motorola the maker of the cell phone, for a fraction of the price of the one at Walmart.  I placed the order and within a few days, I had my new battery.  I put it into the original phone and I've been using it now for a couple of months with no problems.  Thank you Amazon and their partner, the company that actually shipped the battery.
