Is there any way to get the battery style chips for R3000?

I have your refillable cartridges and they have the auto chips on them now. I have a set of the old battery chips but a couples of them are getting messed up. I will some times swap one of these chips in to force the printer to think the cartridge is new and then go back. Normally this is with the matte and photo black when switching from one to the other. I would just like to have a few spares around.

I believe all you need to do is find a replacement battery and your chips will be ok.

We do not have battery chips any longer for the reason you state above and for other reasons including the importation of batteries into the country.

I suggest getting a set of backup ARC chips and always make sure to print until PK resets to full (if it’s very low) before switching to MK.
