Nikon CoolPix 995 uses internal capacitor to keep internal clock running when main battery is removed for recharge. Replacement of the capacitor is a 'Factory Job'. How can one replace a failing internal clock capacitor?

How do I charge a nikon clock battery

The clock battery is internal and cannot be removed or replaced except by a technician. It is recharged by your regular rechargeable battery, so there is no separate charging procedure. If you find that your clock and other permanent settings are being list when you remove your regular battery for charging, then it's an issue with the internal battery and should go to repair.

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.

Battery exhausted even after charging.

There are two possibilities. First, rechargeable batteries do not last forever. Take out your rechargeable batteries and replace them with non-rechargeable ones for test purposes. If your camera works ok, it may be that the camera's charger circuit has gone bad. Try charging your batteries on an external charger. If they charge, it is your camera's charger, if they do not hold a charge, it is probably time for new rechargeable batteries.

N 70 blank display solution plz

Not a lot to go on.

If the display shows up when you hold the shutter release down halfway, then the internal battery has drained. This battery-different from the EN-EL3 that serves as the main battery-runs the clock and keeps your settings while the main battery is removed. You may be able to recharge it by putting a fully-charged main battery into the camera and leaving it alone for three days. (This is in your manual.) After three days have passed, turn the camera on. Both displays should work like normal, and it should prompt you to set the clock.

How do I know when an EN-EL! for the Nikon Coolpix 5000 is fully charged? what do the following conditions indicate? 1. Charger red light flashing 2. charger red light steady 3. charger red light...

Charger flashing red indicates the battery is still not full and is in the process of recharging.
Red light steady indicates your battery is fully charged and ready to operate with your Coolpix 5000.
When red light is off it indicates there is no battery inserted or the charger is not pluged in.

My nikon coolpix 995 won't download pictures

Consider NOT connecting your camera to your computer.

The best way to download pictures from your camera to your computer involves removing the memory card from the camera and plugging it into a card reader (either built-in to the computer or connected via USB or FireWire). This is likely to be faster than connecting the camera to the computer, and won't run down your camera's batteries.

Once the card is plugged in, it will appear to your computer as a removable drive. You can use the operating system's drag&drop facility to copy pictures from the card to the computer's hard drive, the same way you copy any other files. Or you can use Nikon Transfer or any other photo cataloging program.

Every time I change the battery on the coolpix 995 I have to reset date and time and all other settings. I never had to do this with my 990. How do I keep all settings , including film quality , unchanged...

Your problem is that your camera actually has two batteries. There's the obvious user-accessible one but there's also a tiny rechargeable one hidden inside the camera which recharges from the main battery. The smaller battery is designed to provide has just enough power to maintain the camera's memory of time and date settings for up to a few months when the camera isn't being used.

Like all rechargeables, it doesn't last forever and needs to be replaced to fix the problem. Unfortunately, it's not easy to get at and the camera must be partially dismantled to access it. It's been a long while since I took a 995 apart simply because there are so few left in working order; yours is nearly ten years old and it was only designed to last a maximum of five years so has done really well.

I cannot provide a link to a free servicing manual, but if you search online you should find one but it will cost more than your camera is worth. In any case, I strongly advise you not to bother: your camera may be into extreme old age (compared to it's original design life) but it still works mostly correctly. Disturbing it by taking it apart is likely to cause more problems than it solves. If I recall correctly, the internal battery is not especially difficult to get to, but is soldered in place and so is not easy to replace. It's also very easy to ruin the new battery by getting it to hot when re-soldering it back in.

The 995 was a fine camera in it's time, but like all old digital cameras is now virtually worthless simply due to the fact that it's now immensely obsolete and also due to the uncertainty of knowing what other component will fail next due to age or wear. My sincere advice is to live with the fault and continue to enjoy use of the camera while you still can. It's extremely surprising that the rotating body joint hasn't yet failed, and the fact that the sensor still works is also impressive. If nothing else kills the camera, it will likely be the sensor and probably in the near future. You won't find that modern Nikon consumer-grade models are anywhere near as well built.

Problem with Nikon Coolpix Digital Camera internal battery


This is a design glitch with these Nikons and many people are complaining about it. The clock battery is supposed to take a small charge from the main battery - enough to maintain the settings when the camera is not in use. However the clock battery that is used is not sufficiently strong enough to hold a charge for an adequate length of time.

As this is somewhat of a design flaw it is unlikely that a new clock battery will make any significant difference to the problem you are experiencing. Neither is it a user serviceable job and for these reasons I do not recommend that you try to replace the clock battery.

Nikon themselves say the following;

"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."

Hope this helps. Thanks for using FixYa.

Clock battery won't recharge

Change to Ni-Mah rechargeables at the highest capacity you can find. If still in trouble it will suggest the internal battery has died - and a replacement is a repair job which will be pricey if feasible So just live without that feature.
