Konica minolta with dead lithium batteries

[pickle8486]

Techs! Please give me some ideas as how you are replacing the SOLDERED ON lithium batteries that's on the main pwb. Photos and suggestions needed. My idea went down in flames as the metal tabs are so delicate. I thought I could just use a female connector with a battery case but the metal tabs are like tin foil.

Initially I bought the original lithium battery for replacing but once I found out that the PCB needs the battery power at all times I soldered wires on the battery, protect it wih a heat shrink tube).
Just solder the wires on the original battery contact pins (close to the PCB) and then remove the old battery with a cutter. I know it's not beautiful

If you have to buy batteries I'd tried to find some that already comes with connection wires and isolation.

LOL sorry, haven't taken any

Imagine using something like this:

CMOS Batterie CR2032 mit Stecker, Backup Lithium Batterie, Stecker ca. 3,2x4mm | CMOS BackUp | Lithium Batterien | Batterien | Akkushop

And handle it like this:

+/- colors might be wrong for artistical reasons^^

Re: Konica minolta with dead lithium batteries

Thanks for posting. I think there is going to be a rash of batteries needing replacement. I wonder if the ghv-m1 firmware will do anything to avoid having to do all of this.

Re: Konica minolta with dead lithium batteries

I'm not shure, we had a phase with a some cases years ago but most machines (there aren't many in the left in the field) are working fine with the initial battery.
I have the feeling that there was a "bad batch" of batteries used in production causing this problems only sporadically.
It won't hurt to check the battery voltage during service visits and replace it if you notice a voltage drop but I wouldn't swap them all the time.

Re: Konica minolta with dead lithium batteries

Konica Minolta made the recommendation that the customer should not turn off the device to avoid the problem. I'm wondering if changing the battery while the device it's on would also be a solution... ?

LOL good luck with changing a soldered battery during operation

That KM recommendation also sounds lika a joke. In most cases the affected MFPs has been switched on 24/7 but sometimes you can't avoid it, like if you move the machine or do certain repair jobs.
Another thing is that many dealers has a collection of 2nd hand MFPs in store for refurb purposes - no way to power them all time.

Re: Konica minolta with dead lithium batteries

On the subject of batteries, I have a 4750 with the date in 2000 year.


When I update date and time, the panel freezes.


Anyone for a tip? I didn't find battery.

Hey guys!
I've never done this procedure myself, but I've found all these accessories, which I think solve your problems.
I imagined that it can work and the aesthetics of the equipment is not too ugly.
I found in an electronics store in my city the CR2477 lithium battery similar to the MFPB and analyzed it to assemble
that way there with a connector and insulate with a shrink-wrap around the battery so you don't have an electrical short.
I hope to help members with this tip.
Thanks

I think the recommedation from KM was to "Advise the customer to not to power off or unplug the device until a new MFPB can be installed."

is there a date/time setting in service mode like that settings you had to do if you install the A3 models?
