Here is a copy of the complaint that I lodged with P&G today:
I wish to lodge a formal Complaint regarding leaking Duracell AA Batteries.

Over the last 12 months, I have had numerous situations where Duracell AA Batteries have leaked inside of various pieces of equipment.

All of these batteries were within date range. They made a mess and caused discolourization to the equipment.

The number of batteries that I have replaced over the last year due to leakage, is more than 10. The latest was today (8/13/2010) where I went to replace the batteries in a handheld aviation radio, only to find that 4 out of the 6 batteries had leaked...again! This had happened to this radio with Duracell batteries back in January as well.

I've had enough!
I want an appology!

Yours, a disgruntled customer,
Paul Carew.
