Chosen Solution

I have a Sanyo VPC-E2100. All was working fine with it. Then the batteries went flat. Bought some more, went flat. Bought some good rechargeable ones. I have discovered if I leave them in the camera they will go flat, quite quickly. If I take one out, and then put it in when I want to take photos, all is fine. But that is a REAL nuisance. What is going on, and what can I do about it?

Hi @jmbkiwi , Thank you for doing what I suggested. One other thing that I forgot to ask. Did you change the setting for the type of battery that you installed? If so please ignore this question. Go to Settings > Battery Type (Click on image to enlarge it for better viewing)

I personally think that 12 hours is far too short a time to hold the settings with the battery removed. I may be wrong about this of course. Most other cameras which employ the same method of retaining the settings with the battery removed all seem to be able to hold them for a least 24 hours if not longer. Unfortunately as I cannot find a service manual, (or even a video online) on how to dis-assemble your camera so as to gain access to the relevant section in the camera to see if it is actually the problem, I’m afraid that I cannot suggest any other course of action except to take it to an authorized Sanyo camera repair service to see if the problem can be resolved by them.

Almost all electronic devices (now) are always on in low current mode checking to see if you have pressed the power on button. So if you put your device away long enough (Never turning it on) the small drain on the battery will discharge it until its dead. So store your batteries outside of the camera. The exceptions to this are devices that have a real switch that disconnects power to the device. Sadly the people designing things are pretty dumb so we have things like phones that are never really “off” unless you take out the battery.
