Answer to: Battery replacement for rechargeable norelco razorI replaced my Norelco shaver batteries about five years ago. It has worked great ever since. I didn't follow a formal disassembly procedure. I pretty much just took things apart until I got to the battery. Some simple soldering was involved. It wasn't pretty, but it worked.
