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

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.
