My camera seems to have a serious fault it seems the battery compartment has an overheating problem which could lead to explosion or fire.
I work as a surveyor and take about 7,000 pictures a year so tend to replace my camera every year, the Powershot A640 was my new camera for this year.
When I attempted to use it for the first time I inserted some AA NI-MH Rechargable Batteries (From my previous A series Canon Camera) and put the A640 in its carry case attached to my belt. 15 or so minutes later as I was at the top of a ladder I noticed smoke and heat coming from the carry case. I removed the camera which was extremely hot, burning my hand in the process, I managed to open the battery compartment to see what was going on and found that half the camera had melted (was Soft to the Touch) and my batteries had overheated and are bonded to the battery compartment. I found out from subsequent searches that the A540 had some overheating problems of a similar nature however I did not realise how serious the problem was and that it can also affect other more expensive Canon cameras like the A640. In the space of 15mins my A640 had overheated to such an extent that not only had it melted my carrycase interior but the battery compartment had welded the carry strap to the hand grip and made all the metal buttons on the top pop out. Ironically even though it burnt me I am just grateful that I had the camera on me. I would dread to think what could have happend if it was in my filing cabinet in the office or in the boot of my car (places I normally store it) when this overheating occured as it could have caused a fire in less than half an hour. I contacted Canon UK and they were not bothered or fussed at all they just told me to return it to the dealer I purchased it from as it was less than a week old.
I wanted to find out if any other users had experienced a similar problem and also what I should do.
I do not want another Canon A640 user to go through what I did. I use my camera everyday as a work tool and the last thing I expect from a Canon Camera is for it to maim, kill me or burn my business down.
