Keeps showing change batteries canon camera - Canon Cameras

Use alkiline, or the type battery your camera asked for
Put them in correctly.

That battery keeps the clock running when the main battery runs down or is not in the camera (as when you take it out to charge it). It simply keeps you from having to reenter the date and time each time you change/charge the battery.

my canon powershot a495 has a problem.
it always shows low battery and turns off. i have changed to new batteries three times but the same problem. i bought 3 months ago

I had the same problem. Here's the solution. Go into menu settings, then over to tools, select reset all at the bottom of options list. You may have to re-enter the date and time. This solved the low battery problem for me. I hope this helps.

Have you been to the Canon website to see if there are any firmware updates for your camera?

1. use alkaline batteries or rechargeable NiMH batteries
2. you may need to clean and adjust the springs inside the battery compartment

Why my camera keeps saying ‘change battery’ even with new batteries?

Hello!

I think I found the soultion.
So when the camera shows that changing battery is needed take those batteries to a discman or hand lamp or any other tool to exhaust the batteries completely. It's necessary becasue the camera can't do it and some charge can remain in the batteries and recharging them in this state leads the batteries to go wrong. So charge them after a total exhaust!
This worked for me.

Peace!

This sounds like it might be a defective CCD imager. Take a picture and see if it is also black. If so, Canon should fix this for you for free, including free shipping both ways. This is regardless of your camera's warranty status. Please check the following two links for more info:

Applicable cameras include:
A40, A60, A70, A75, A80, A85, A95, A300, A310, S1 IS, S60, S200, S230, S330, S400, S410, S500, SD100, SD110, IXUS V2/300/400/430/500, IXY Digital 200a/300a/400/450/500

The little 3 volt button battery is the clock battery for the camera. It keeps track of date and time.

Some of The Canon Powershot A530 and A540 cameras are subject to an advisory recall. Seems that a small spring on the battery compartment door can short out the batteries. Suspect this of yours, in that you mention that your batteries aren't lasting long. If your camera is on the list, Canon should fix this for you for free, including free shipping both ways. This is regardless of your camera's warranty status. Please check the following link for more info:

Finally, make sure you're using rechargeable NiMH batteries rated 2500 mah or better. Digital cameras just use too much power for standard alkaline batteries.

You need to use 2100 mAH or 2300 mAh rechargeable batteries - alkaline batteries will not maintain the high level of power required.
