Reemplazo de la batería Panasonic ES-RF31

Thanks Daniel,

I followed your instructions and all went well. One thing to add: after re-assembly of the (loaded) battery my razor would not turn on. At first I thought of a bad contact, but it turned out that the razor needed a few minutes plugged into the power supply. After that it worked fine. I suspect, that the load-control hardware needs the external power to reset itself.

Cheers, Nils

Hello Nils!

Thanks for the hint.

Glad to hear that your razor works again!

Greetings

Daniel, thank you very much for instruction.

Unfortunetly, into shaver I found only 1 battery.

Because used 3.7 v element, I prepared 2 x 1.2 v batteries.

My razor was the Panasonic ES8103S and the disassembly process was similar. From the pictures above, the battery looks the same. My razor actually had a piece under the slide-off cover that was totally rusted so I will just buy a new one on Amazon for $50. For future reference, I would like to know where you get the replacement battery? There is no model number on the battery and I couldn’t find any info online.

A great guide, I have just successfully changed my razor battery. I found the OE battery available on Ebay in the UK. Many thanks to Daniel and kudos to Panasonic for making the job simple.
