Replacement of the internal battery

If I take my batteries out, even for a second, all the settings reset. Also the batteries run down very fast (over a few hours), even if the camera is not in use. I assume that I need to replace the internal battery but do not know how to access it. After undoing all the screws I can see, the back cover appears to be still held on at the top, near the viewfinder. Do you know how to replace the internal battery or get the cover off so I can find it?

Re: replacement of the internal battery

Hi, There is a capacitor in the unit that holds a charge and saves your settings. You can find where to order the part, and some take apart pics here (not my page, just a link I found online): Hope that helps you out!

DO NOT try this solution at home. The pics neglect an important and vital piece of information namely that the capacitor is soldered in to place. Easy enough (though not simple) to get to the point of removing the old capacitor. Impossible to replace with the ordered part unless you are an expert at microsolder in very tight spaces. One to leave to the experts I think.

Re: replacement of the internal battery

Both of these cameras have a small MnO2Li coin battery type CR2025.

It five minutes work to replace and you don't need to take the whole camera apart. The battery is located in a rubber holder located on the 1400 underneath the hand grip. You need a stout tooth pick or unbent paper clip to pull it out.

Alterntively take your cemera to a real photo place where they should do the replacement for the cost of the new battery.

Re: replacement of the internal battery

Is there an internal battery? Taking a camera apart is not a good idea. Are you sure you are using the specified batteries as laid down in the Manual? Try Olympus Technical support don't tell them you have had it apart.

The date and time will not stay set. I set the date time . take pictures and when I shut the camera off. the next time I turn it on the date and time is zeros again...

The world of compact digital cameras is fast and furious blink and you'll miss the new model. These pocket point and shooters are cram packed full of features that most people neglect to utilize. So it's uncommon for the problem you describe to occur however it's simple and fairly inexpensive to repair. What you need is to replace the camera's internal battery which holds the custom functions and date time settings after the camera has been shut off. Normal internal battery life is greater then five years and a lot of my cameras go ten years before replacement. A camera store not your big box type but one that actually sells cameras and does film and print processing. I don't know where you are to even suggest someone. However at the bottom of the camera where you would place the memory card and batteries there is another slot for the internal battery. This link half way down the page will show the open battery door and where the internal battery is located.

There has been few complaints or problem with this camera except for the very weak internal flash.

Nikon Coolpix keep resetting Time and Date and menu settings.


I am listing this tip for the Nikon Coolpix 995, but the tip is valid for all Nikon Coolpix models.

The Nikon cool pix settings are saved into an internal memory.

The internal memory is maintained by an internal rechargeable battery, that is recharged from the main Li-Ion battery.

If you leave your Nikon overnight with no main battery, or if the Li-Ion batteries have drained, then the internal battery will also drain , resetting the clock and other settings, saved on the internal memory. The camera may even drain in about 6 hours depending on the camera, normally it takes at least 12 hrs to drain the clock battery.

If the internal battery is resetting immediately, after you set the clock, or just after few minutes, then the clock battery must be replaced.

The camera must be disassembled completely to replace the battery located on one of the two main internal boards.

Nikon says that the clock battery loosing charge is normal. I quote what they say on the publication titled " The Nikon Guide to digital photography with Coolpix"

"Backup battery of the clock
The clock-calendar is powered by a separate rechargeable battery, which is charged as necessary when the main battery is installed. If the camera has been stored with the main battery removed for a long period of time, the clock may need to be reset. Once the main battery has been reinserted, the clock battery will recharge in several hours, during which time the main battery should be left in the camera."
Original file: Download here

If the clock does not work at all, and is resetting immediately, even though the Li-Ion batteries are fully charged, then the best thing to do is calling Nikon, at the number listed on the owners manual, telling them that you did not do any improper use of the camera, and trying to get the fault repaired as factory defect. That is not always possible, and the decision depends on Nikon customer service.

Konica Revio KD-400Z. Internal battery appears to have expired meaning I have to reset date etc. each time I remove either the l-ion battery or the SD for downloading. Can I fit new internal battery and...

First the bad news. Konica got out of the camera business in 2006...all service is now handled by Sony. The internal battery is not user replaceable. It is a rechargeable battery that recharges itself from the regular battery. It takes about 3 hours to accomplish this. If you remove the main battery for 24 hours, the internal completely runs down and all date and time settings are lost. If after setting them again, you don't leave the fully charged main battery in the camera for at least 3 hours, they will disappear again.

Is there an internal battery for the time and the date?

Manual says: "After installing the batteries, the set-time/date message may appear on the monitor. The clock and calendar are set in section 3 of the setup menu (p. 18)."

In fact if you replace batteries really fast (in a minute or two) and time is reset the internal battery is probably exhausted/broken. You have to decide if it is worth of repairing.

My Z1 has 6 years and the clock does't forget time. Maybe next time i'll be surprised...

Fuji FinePix S9000 battery change clears date/time.


I started having a similar problem with my Fuji FinePix F10 after about 3 1/2 years of problem-free use. Another poster had some really helpful advice which I thought I'd pass on. It seems there is an internal battery or capacitor which basically fails after a while, meaning date/time settings etc are lost when the battery is removed. (Some people claim this is a motherboard/chip problem instead - seems to be contentious!) So the camera is faulty, but the problem can be worked around.

The advice I found, which worked for my camera, was this:

- Turn off camera and leave off for approx 15 seconds before opening battery door.
- Change battery quickly (within a few seconds).
- Close battery door and leave camera off for approx 15 secs before turning back on.

This retained all settings when I tested it multiple times. I imagine it might not work if changing over a totally dead battery though.

Hope it helps!

Cybershot will not store clock settings

The internal battery is bad. It has to be replaced. Contact your local Sony service center, but if they ask too much, you can contact me at and I will give you a good price.

I have a Sony Cybershot DSC-P92. I have replaced and recharged batteries but the camera will not turn on. The light blinks on and the tone sounds and then nothing.

Take the camera card out of the camera.

This is a factory reset procedure so you will loose any pics in the internal memory!!

Turn the camera off and take the battery out (including AC power). move the power switch to the ON position and hold down the power button for 15 seconds, then move the power switch to the OFF position and release the button, put the battery back in and power on the camera.
NOTE: you will have to reset the time and date + any previous user settings.

Hope this helps!!

Good luck

Camera says brand new batteries are dead, then shuts down

It is possible that the batteries are dead (they might be faulty or too old) even when they are out of the package, though unlikely. Try another set of batteries, and if these don't work, you'll probably have to send it for a checkup.
