I did everything possible to find help as I did not accept the answer from Norelco. They told me that there is no way to change the battery except by a qualified repair shop. I made them admit that they basically made a consumable device so they can get you to buy new shavers in the future - in so many words.
I finally pried the thing open as carefully as I could. Once opened, you will find 2 batteries glued together. They are Ni-Cd 2,4 volt - 600 mAh batteries. Looking all over, the only store that helped me was Battery Plus. There are stores all over the country

They sold me two 1.2v 1000mAh batteries for $3.50 each. For another $5 they spot welded them together with tabs for soldering the 2 wires on.
Okay, after getting the new batteries, I went back to my old batteries and slowly pried the tabs of the top. They pretty much snap off as they are only slightly tap welded on.
I then took out my model soldering gun and with a little patience, soldered the two wires on to the new leads on the new batteries.
Within minutes, I had the thing put back together and charging. It works great and now I can tell all of those who said it can't be done - or those who wanted $40 to refurbish it, to go scratch - I GOT MY SHAVER BACK!!!!
We all need to learn to stop living in a consumable world. I have a feeling due to the economy we are facing, we will all try to save money in this manner.
Good Luck!!!
