A590. Why does it indicate 'replace batteries' even after new ones installed?

SOURCE: Canon S2IS " change the batteries" problem

This worked for me after having the persistent "Replace the batteries" problem for about a year straight.

1. Reset the camera, according to the instructions in the manual. (Power on, hold MENU for 5+ seconds, select “OK”, wait, turn camera off).
2. Remove the date/time battery for two minutes (the tiny one in the battery compartment in its own little plastic holder). Replace after 2+ minutes.
3. Important: Insert freshly charged batteries into the camera.

I tried everything short of getting a new camera, and this was the ONLY thing to work for me. Its also simple enough that it takes 3 minutes to do, in case it were to ever happen again while on vacation, etc.

Good luck and I hope this helps.

Off-the-shelf NiMH rechargeable batteries, and the special lithium nonrechargeablebatteries sold as esepcially good for camera use, don't have enough voltage output for this camera. Try using regular alkaline batteries or the rechargeables sold by the manufacturer.

Don't use regular alkaline batteries (even though you can...) It's a pain to splurge for the more expensive lithium or photo-specific batteries, but they do last. I take A LOT of pictures with my A590, and can usually get several hundred shots out of a set of good batteries. Try Energizer's web site for a coupon, sometimes they have them available.

Have a look at CNET.COM
I have the same camera and the same fault. CNET are suggesting Canon should recall the camera because of this fault. I did see elsewhere on the net that it was a battery contact problem and a home-made modification could fix it. The camera takes great pictures but I can only use it if I have a batch of fully charged cells with me, and keep changing them. If I go out I take my Olympus or Fuji with me.

Use NMH type batteries standard batteries are not good enough for the write load that this camera draws. I think it recomjmends this in your manual if you still have it.

also dont use rechargables
