Whenever I switch on the camera, the battery low indicator comes on though the batteries are fully charged. When I open and close the battery container lid, the low battery indicator does sometimes disappear.

Hi Have you tried resetting the camera back to factory settings? This should clear up any problems...if it doesn't it may at least let you know what the problem is? Also...do not use an SD card no bigger than 2 gigs, What is thee display showing? Make sure the date and time are correct! Get back to me if you need any more help...Thanks...John,

I have connected my PowerShot A2000IS that was doing the same thing for me and I discovered the following:
1) The unit works fine even down to 2.5V providing the supply source (i.e. batteries can deliver 500 mA for a short burst during startup, i.e. when the camera's lens is extended). The camera draws 300mA with screen on after the initial startup current has settled. This means that the camera may not work with batteries like normal alkaline as these don't normally supply large currents, like NI-MH and NI-Cd can.
2) I found that if I lowered the voltage down to (using my bench power supply) that the low power indicator come on at just under 2.5 Vs, BUT once it has indicated low battery, turning the voltage back up to 3V didn't remove the low battery indication.
3) Finally I connected my fully charged (with combined voltage of 2.7V) Ni-Mh rechargeables (old and well used) using wires to allow me to measure their voltage and I found that when I turned on the camera the voltage dipped to 2.3V, but come up after the lens was deployed.

Conclusion and recommendations:
a) Get some new high quality Ni-Mh cells.
b) Don't use Alkaline cells (even Duracell brand might not handle it).
c) Forget Ni-Cd as terminal voltage would be at best 2.6V which doesn

With a fully charged battery and assuming that the battery is good. You need to check on/off switch, I often found the switch doesn't completly close and therefore, one side of switch is B+ but on other side the voltage is low that why low battery indicator keep beeping. Do that and see if it fix.
Good luck!

First, even a fully charged battery may not be working right - VERY common.
Does the camera do this on two batteries, one old and one much newer? (I say this because lithium batteries are good for about 500 charges - if you are over this, the batteries will always read weak...)
A service shop can test the camera and see if the battery is reading correctly. A service shop may allow you to try the SHOP's good battery in your camera and see if it reads right. If OK, you need a new battery.

The service shop can reload the operating data into your camera - I have fixed them this way myself.
If not, the circuit board that handles charging and batteries may run you $275 plus labour. (The board is not repairable)

Hi!
The switch that detects if battery cover is closed is broken. You can open the battery cover and look under it, you should see a small hole with a small black switch in it. If you have experience in repairs and / or soldering, you can fix it yourself - just shorten the switch. If you can't do it yourself, just give it to any local camera or mobile phone repair shop, they should be able to do it without problems.

Hope this helps!

Try removing the battery for a couple of seconds then insert it again. Click on the power button, it should turn on and turn it off again to close the lens.

Same thing happened to me when I used alkaline batteries. Have you tried fully charged NiMH? If not you may have a "leak". Your next option is the service center.

Sounds like your battery isn't taking a charge so I would say your battery is the problem

To resolve the annoying "change the batteries" problem. Goto menu, choose yellow menu, select
file No. reset to ON. Turn camera off and back on.

Voila fixed.

I found out the hard way that you should never use alkaline batteries in a Digital Camera. I thought my camera had a fundamental flaw (power kept going off whenever I tried to take a photo or record a video and the shutter blades half closed) even though it was only 2 months old. I nearly wrote it off but all along the problem was that I was using alkaline batteries, which incidentally were enclosed with the camera in the box!! Once I switched to NiMH (Nickel) batteries the camera worked fine and the fault completely vanished! These NiMH batteries are avaiable in most electrical shops i.e currys/comet in the UK. They must be charged before use. They are more expensive than alkaline batteries (£8-£9 for 4) but as they are rechargable they last a long time.
