Re: Low Battery Power

Clean battery contact on the cover and if possible on the far side of the battery compartment (spring and metal connector). You can use fine abrasive such as 3m or scotchbrite. Oxidation buildup increases the reistance and the camera ' thinks' that the battery is depleted.

Low battery on screen and shut off

These cameras need good batteries. Make sure you either are using quality Alkaline batteries or NiMH rechargeable.

Battery not charge

the battery may have developed a memory from continually recharging a partially used battery. The battery charges to this point and reads fully charged but when used it shows as flat because the charged portion is the bit that is used and not the whole battery. Replace the battery with a new one and only charge the battery when it shows as flat.

Change the batteries message keeps appearing even with fresh batteries. The camera turns on then immediately turns off What's up?

This actually a really common problem among Canon point and shoot cameras. There are a couple of methods that have worked well for others.

1. Open the battery compartment and remove the batteries. Then take a regular wooden pencil and place the eraser end down onto the battery contacts. Rotate the pencil to remove any corrosion. Sometimes a lack of proper battery contact will result in the low battery indicator.

2. Take a toothpick and wedge the tip under the battery contact and break it off. This will put more pressure between battery and contacts.

This is a bit technical and will probably void your warranty, but might be worth the try.

First step to trouble shoot. Connect a low voltage ohm-meter to the battery contacts inside the camera. Try to turn camera on. If you get a reading, write down the number of ohms. If possible, compare this with a brand new one, if store will let you. Or call the USA distributor. If ohms number is way low, you have problems inside the camera. If number is normal, the battery is no good.

See if the menu has a battery type setting. Some cameras have the ability to use different battery types (alkaline, Ni-Cad, Lithium, ect) and have power management presets to accurately indicate a low battery condition. If you are set to one type an install another, a false reading would result.

Keeps saying low battery but has new batteries I have the same problem. New batteries but camera shows low battery and only stays on for 2-3 minutes.

Your camera is a power hog. Try using the new high power battteries. Ther are expensive but generally work in this situation. There could also be a problem with the camera, I can't rule that out.

Low battery message, sent back to canon to repair and still having same problem..can i send back yet again. where to? or can i get a new one.

I had this same problem. I tried this procedure and it seems to have worked so far:

1. run a set of batteries down in the camera so the voltage is so low the camera won't even power up fully.

2. put some cheap (non-alkaline) batteries in and run these down.

3. get some hi-power alkaline batteries (the kind that are marketed as 'photo' batteries or similar, they do cost more) and put these in. Hopefully the 'low battery' indicator has now been reset.

This worked for me.
