Internal battery in cameras....
Feb 26, 2020 13:17:22 #
Since there was a post on D300 whose battery died I got curious, as usual.
Today I scratched that itch.
Nikon does use internal battery (big surprise there). This battery is easily accessible for DIY folks.
You just need to unscrew the camera back, remove it carefully.
The battery is revealed. The - contact is soldered to a small metal connector itself connected to the camera board.
To change the battery is simple:
- remove the thin metal frame protecting the circuit for ease of access.
- 'unsolder' the metal connector from the board
- Unsolder it from the battery.
- Take the battery to a jewelry store to get the exact model
- solder the metal connector to the battery (careful of polarity)
- Solder the connector to the board.
- Re-attache the protective metal frame
- position and re-screw the back onto the camera body
You are done.

That 'un-soldering' and soldering will require advance DIY soldering practice I guess. Even more on the board side connector

It is a surprise to you that there is a internal batterie????? Cameras have and always had internal batteries, that hasn't changed in a hundred years!

There are internal batteries and internal batteries. We're talking about small lithium batteries that keep certain circuits powered like settings, time etc, even if there is no battery or a dead battery inserted to power the camera. Every computer has one of these batteries to keep the bios/clock powered, even if you unplug it or remove the main battery. I personally wouldn't go into my Nikon D810 with a soldering iron, and I'm pretty good at soldering.

Super capacitors have been used in place of the small battery that keeps the clock running. Today with flash memories the battery is only needed for the time and not the settings.

I am quite aware and just threw that post out thinking that some may research and stumble across the super caps used in numerous cameras.

Who mentioned capacitors?
Just wondering how that fit in this question.

Some cameras use capacitors. Theses are not replaceable or hard to do.
While this is not mentioned in the original post, it is a possibility for other cameras. No big deal.

I brought up capacitors because that is actually what the internal power is in many cameras. It is temporarily charged by the external battery. I was hoping to stimulate some to take a couple minutes and gain a little first hand info.

Self-doubt can be an ally. It can serve as an indicator of the need for a new camera.

Some early camcorders and cameras have a coin cell slide-out battery. My Kodak DCS PRO SLR/14nx has one, along with my Sony TR-4 camcorder.

I never thought about it before, but I can understand how that would be now. The question I have is how long do these capacitors maintain their charge if the main battery is removed from the camera.
I got a Seiko Kinetic watch more than 20 years ago. It was one of the first ones. A generator in the watch, powered by your wrist and arm movements, charged a capacitor. The capacitor would keep the watch running for 3 days. If you didn't wear it for 3 days, it stopped running. The capacitor failed twice and was replaced twice. When it failed a third time, Seiko put a rechargeable lithium battery in the watch. It would keep the watch running for 6 months on full charge. That first battery lasted for more than 10 years. They just replaced it again last year.
I like to hold onto some things.
