Did you check battery contacts?There are some threads about it:http://chdk.setepontos.com/index.php?topic=9024.msg93846#msg93846
On analysis, I see no benefit from cleaning the contacts (not that it hurt to try!) or bending them.

But if your battery contacts are dirty or corroded and not making a good connection, you will have a series resistance through the contacts which will produce a voltage drop when the camera draws current from the battery. If the resistance is large enough (5 ohms would be enough to give you a 1V drop) then the camera will think the batteries are exhausted (it measures battery voltage after the series resistance of the contacts). Typically, rechargable batteries start at a lower voltage so you would see the effect sooner than with disposable batteries.
Again, this is a red herring. My contacts are clean; my contacts are making contact.My original question related to CHDK and whether a solution had been found to the a570's actual problem, which is that it reads fully charged batteries as low-power or discharged batteries.
