Hello,

 

The clock of my D5100 keeps needing to be set. 

 

Does anyone know what battery I have to replace?

 

I believe its located on the Motherboard.

 

Thanks.

In answer to my own post.

 

I found this article:

https://photo.stacke...ing-the-battery

Which says:

"The battery is a MS518SE 3 Volt Lithium battery."

 

I've checked the D5100 Manual

https://download.nik...RM_EU(En)02.pdf

But it doesnt state the model or part number of the clock battery.

 

I've asked different sellers on eBay,

But they can't confirm or deny if the MS518SE is the correct battery.

 

Does anyone here know?

 

Thanks.

I don’t know the battery model, neither how the battery is fixed.

Though I think that if you want to open the camerabody for replacing it yourself, you will find the old battery with its specifications. You could order the replacement battery at that moment.

While warranty is unlikely to be an issue with this camera model, obviously opening the camera body will require the good tools and a bit of technical knowledge.

Why not check with a local camera store, who might also do the replacement.

Nikon D5xxx series have a capacitor or internal battery that keeps the clock and settings active while the battery is being changed. If the camera is left with a dead battery for a very long time, the capacitor or battery may become fully discharged and dysfunctional.

I think it's in the camera motherboard, not easy access, sorry. :(

 

My cameras from flagship series have very easy access to this battery that it's in the grip area it's a CR1616 I changed few of them, located close to the camera main battery with a plastic cover.

 

Nobody knows why Nikon NOT create this kind of easy access in all camera models that use battery clock. Even rechargeable batteries die, so if you don't use the camera with regularity, and you don't use it during months or years, this happens sooner than late.

This shit start to happen when that camera doesn't have battery or the main battery it's 0% for long time inside the camera.

 

Note : I know it is disturbing entering the date every time you're ON again the camera, but only affect to this, when you enter it will still remember again until you're OFF the camera again. The camera will work as usual.

Hi, @Jerry_ and @La Bikina

 

Thanks both for replying.

Both of my Nikon D5100s are about 10 years old, they have been super reliable workhorses.

But the warranty has long expired.

 

As I work with them a lot, I bypass the battery with a mains adapter, to save swapping out batteries all the time.

This could possibly be the reason why the CPU Clock Batteries have become depleted.

So I will swap back to using the EN-E14A Li-Ion batteries to see if thats helps to recharge the CPU clock batteries.

 

I've noticed that sometimes when recording video the camera turns itself off, it this just a coincidence or another symptom of the clock battery issue?

 

I found a D5100 tear down here on Nikon D5100 Teardown - iFixit

They gave it a 2 out of 10 rating with 10 being the easiest to fix, so the D5100 is not the best when to comes to servicing & repairs.
 

I can see the battery on the motherboard in this photo:

I think I can see "S518SE" written on the battery, with the "M" hidden under the clasp.

A second opinion would be appreciated.

 

Thanks.

Hi,

If it is a MS518SE cell battery (based on the picture I also read S518SE) then it won’t recharge, no matter if you use a direct main or a battery to power the camera.
At 10 years of use, it has well lasted and is now empty.


Looking at the link to the ifixit site, you will have to go to mid-step 6 for replacement of the battery. The good thing is that up to that step there seems to be no (un)soldering, just unplugging some cables. As they however point there will be a number of Philips screws to remove (and later re-insert), which should not be to complicate as they are likely mostly the same size - just pay attention to loose none.

As you have two cameras, maybe you could document and post the operation?

Thanks everyone for your help and advice, it's appreciated.

  • I think I will order the batteries,
  • Disassemble one camera,
  • Try to repair it,
  • I'll record the process,
  • And if I'm successful I'll fix the second camera.

Either way I will report back here.

 

Thank you.

One thing to remember is that the cross-head screws are JIS, not Phillips. Using the wrong driver will lead to rounded heads.

I'm glad you posted, thank you!

 

I have this screwdriver set. (See the image attached). Are any of these suitable?

 

Kind Regards.

They look to be more for tamperproof heads than JIS…

Here is an article about the differences…
