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.

Why does the date/time on my L18 keep changing itself

This indicates that the built-in battery of the camera is damaged.(All digital cameras have a tiny built-in battery)

Replace that battery and you'll be OK. Don't ask me how to do that change. Get the manufacturer to point you to the location of that built-in battery or put it to a service centre.

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.

I have to reset the date and time on my Coolpix L810 everytime that I change the batteries. Why do I have to do this?

The L810 has a small internal long-life battery for maintaining the date, time and other settings. This battery should not be confused with the batteries you use for general camera operation. Like all batteries, that memory back-up battery has a finite life span. You will need to have a camera repair man replace it.

Coolpix 995 hard drive????

I'm sorry for any confusion, I am no expert by any means but that is what the person told me at Wolf Camera. I did see him get the parts/repair book out and he showed me the price it had listed for that repair. I don't know if it will help you but this store is in Nashville,TN located at Hwy.70. Maybe you can call them. Thats all I can tell you, good luck.

Coolpix 995

Wolf Camera diagnosed the camera and determined it to be the hard drive and given that I threw it away and bought a new one. The cost would have been over 200.00 to fix it. They said it is a common problem with the coolpix 995. Goodluck!!

Nikon 5700+remote cable release

I am using the same remote on both a Nikon 990 and 995 coolpix cameras. I had trouble with the 990 but reset the unit to factory default and it appears to work in manual mode. The nikon site says that it may take 10 seconds or so for the camera to relize that it is not connected to a computer via the usb cord.
