getting message to change the batteries after doing so

nonees, the issue here could be your battery compartment door. Make sure that it makes good contact as well as the bottom contacts. If it does, and everything else checks out, replace the RTC ( 'date/time') battery. Even if your regular batteries are fully charged and are making good contact etc, if your RTC battery is discharged, it won't make any difference, and you can get this error message. That battery is in the same compartment as the regular batteries, on the opposite side of the hinge. Extract it with a fingernail, it is situated on the left hand wall of the battery compartment (when the camera is inverted and the compartment open). It is a coin type battery CR1220 Hope this helps, good luck.

"Hi not sure if it would help, try taking the batteries out from the camera and leave it out of camera for a few hrs (2 maybe?). While waiting, try to power on the camera the normal way to discharge any possible remaining power. Then, reinsert the batteries back into the camera and power on to see if it helps.

Some machines somehow needs a full discharge to 'help erase' issues it has and encountered and to restart afresh.. Not sure the terms are correct but thts how i learnt over the years.

Hope the above helps! Good Luck! :)"

"Canon PowerShot SX220 HS in many cases is displaying the error message ""Change the battery pack"" although the battery is fully charged. One solution to this problem is to add some element (paper) between the battery and the battery door to ensure better electric contact.

"Would also suggest testing/ replacing the memory backup battery which is located under a flip out cover on top left side of SX120IS. It is a CR1220 button cell and generates a replace the batteries error even with fresh batteries. If you don’t have a battery tester just pull out this battery and try starting up the camera with fresh AA batteries. If the CR1220 is bad the camera will now start up in picture taking mode.

This seems to be a common error message on a number of older Canon PowerShot cameras especially ones that use AA batteries so worth checking to see if the memory backup is bad and you get this error after putting in a fresh battery."

If you don’t care about the time/date staying between power cycles I was able to just remove the little cr 1220 battery entirely to get rid of the error.

Canon PowerShot A630. I removed the Memory card and reformatted it. It seemed to fix the “change the batteries” problem for now…
