Thank you! It’s a shame the machine was designed without easy servicing for the battery. Otherwise a great rice cooker!

Paul Sharpe - Yanıt

do you fix rice cook

TIM IE - Yanıt

Nice repair. Thanks for sharing.

It looks as if you could replace the battery without doing any soldering. Once you break the yellow plastic surrounding the battery, can't you simply slide the battery out of the metal holder and slide in a new one?

That’s not a holder. It comes from Panasonic with the two leads welded on and the yellow wrap is just there to keep those welds from seeing mechanical stress during shipping of the device it’s soldered into. If you pry the battery out, it’ll just break those spot-welds and won’t hold a new battery. Bottom line: It’s not designed to be user serviceable. It’s a PCB-mounted, soldered-on battery type. Someone on youtube suggested replacing it with a coin cell holder for a different battery size, but to each their own. I’ll probably replace mine with a genuine part from Mouser or Digikey. It’d be nice to use the delay cooking function again without having to set the clock first each time. It definitely is annoying that they expect customers to go to a service center for this. We hardly even have any electronics component stores in the USA anymore.

Note- I have a different model and it has a different battery. Don’t assume these instructions will translate to a different model. But thank you is due to Sirui Wu for sharing these.

Good Morning, when you had the rice cooker apart did you happen to notice if there might be a 120v tap on the power supply? The rice cookers from japan are much less expensive but only come in 100v 50/60hz
