I assume you are using alkaline batteries.

I'm using Duracell rechargables...

The rechargables have a specific lifetime also....are they new?

Claire, there is a second battery for the date/time. When it gets low on power you'll get the same message. You'll see down the side of the camera, where you plug it into your computer....at the bottom of that strip is something you can hook your nail on and pull out. There is a little round battery. Just get a new one of those and your camera should stop giving you that message.

>>My Canon powershot camera keeps showing my batteries are low, yet when I check them with my battery tester they show GOOD. Why is that...This sounds like you have a old set of batteries, put some new ones in and most likely the camera
says good.

thanks luckygardnr, i found that battery for date and time, i never knew it was there. I will get a new one. That is probably the problem because my other batteries are not old.

How old is your camera Clair?
I remember, not long ago you purchased a new camera.
Usually, these batteries last for many years.

my camera is 1 year old.

There are a couple of different kinds of re-chargeable batteries. The older variety is NiCad, and they generally don't last too long especially if you often recharge them before they are totally discharged. They have a 'memory' that can eventually work against you. The newer variety are NiMH. They have no memory and have a much longer useful life. In addition, you can see their power rating stamped on each battery. You should look for 2200 or higher.
