- Replace the dead internal date-time-settings CMOS battery in a Fuji Finepix A210 or A205 digital camera.
This video will show Method #1, which is soldering wires directly to a small button cell battery. A follow-up video will show Method #2, which does not require directly soldering wires to a battery, which is very dangerous, requires outstanding soldering skills, and requires extreme safety to avoid having the battery literally blowup or burst. - Наука та технологія
I would at least desolder the original 614 first lest the xx32 in parallel tries in vain to charge the dead backup cell. There's also the idea of replacing the 614 with a supercap of the same size and voltage, which i think will last indefinitely. Also, don't forget to insulate the xx32 cell before the camera is closed.
Any idea why startup was so slow after the operation?
1) Having owned an A205 for 20 years (as of April 2004) and used almost daily for that entire time, I can say with certainty that occasionally the startup will be slower than other times for completely unknown reason. It has always been that way. I have assumed that it may have something to do with having to charge the flash if it had not been started-up for a while, and these models rely on firing the flash for almost all photos. Another possibility is that I have noticed that this model seems to startup slower if the settings had been wiped due to the dead backup battery, and the startup is always faster when the settings have been retained. So since the settings were wiped when the new battery was installed, the first startup was slower. So probably one of those reasons. I now own several A205 and A210, and they all behave like this.
2) Re - Trying to charge the old battery... I am not worried about that. That old battery is totally open-circuit.
3) Supercap is definitely a possibility. I may do one of these with a supercap, but I honestly just did not want to spend any extra money on the project. I had small button cell batteries that I was not going to use for anything else, so the repair was free. There's no room to put a supercap in the same location as the old battery, so it would still have to be routed into the same location as the button cell battery. It really does not need to be insulated, there is only plastic around that area where I tucked it in, and once the cover is replaced, there is no way for the battery to relocate itself elsewhere. Of course, nothing wrong with putting heatshrink or tape around it.
@@bigslick yes, it's probably the settings being lost the camera will try to charge the flash by default.
Not enough space for a supercap: I've bought a batch of these of the same size and voltage with the 614 from AliExpress but now I wonder if they're really just plain 614 being palm off as "supercaps". A recent supercap I saw inside a Casio swivel lens camera has a supercap that looks like a short electrolytic, maybe that's the minimum size. BTW, have you come across any explanation as to why they can't just use the flash capacitor charge to keep the settings?
@@himeccms893 The discharge pattern from the flash cap would probably damage the IC instantly, or at least cause glitches/corruption. If that would have worked, every manufacturer would have just tied the memory to the flash cap.
Interesting that you mention buying the surface mount supercaps, I literally just placed a small order on Ali for a few of them to play with the concept. The electrolytic style supercaps are certainly legit, and I can surely mount a small size one (ie 1F value) in the same location as where I tucked the button cell battery.
Should the camera turn on without an sd card because I currently don’t have one but when I turn on the switch it flashes the green light and then remains off.
yes, it will turn on (may take 15-20 seconds), screen will come on and say NO CARD.
@@bigslick ok thanks for your help mine must be broken. It only turns on properly when I connect the usb to a wall plug but then it turns off as soon as I remove the usb.
@@isabelbyarugaba2008 AA batteries may be weak. Need to use either rechargeable NiMH or Lithium AA. I find that nothing else works.
@@bigslick that’s brilliant thank you so much for your help!
@@isabelbyarugaba2008 Worth a try. I know these models definitely do not work right with standard AA "heavy duty" batteries or generic AA "general purpose" batteries, and sometimes wont run very long with Alkaline either. But they run good with NiMH rechargeable and Lithium AA.
My finepix205s turns off when switch the knob to either film or photo mode, any idea where to start?
new NiMH or Lithium batteries. Dont use anything else. If that doesn't solve it, then I dont have any other suggestions.
@@bigslick thank you for advice. My last resort is switching the lens module from donor camera.
