Norelco Quadra Action 7864XL Electric Shaver Questions & Answers
How to replace batteriers in norelco quadra electric shaver
The rechargeable batteries are solder into the circuit board of the electric shaver. You'll have to use a soldering iron to de-solder the terminals/tabs from the PCB (printed circuit board) in order to get them out.
Then you'll need new replacement rechargeable batteries to solder back into the shaver.
You can get teh correct replacement batteries from Electric Shaver Service in Lincoln, Nebraska (if you're in the US or Canada). They even do service and repair work in about a week, if you want to have them fix your shaver for you.
Here's a link to the battery page with your shaver model's rechargeable batteries for about $15.00 (plus s&h)

To replace, you will need to remove the back cover by removing the two screws. You may need to extend the long hair trimmer to get to the second screw. Take off back cover to access inside. There are two metal clips that must be unhooked for better access. You can unsolder the batteries from the circuit board but for easier replacement, it is sometimes suggested that you use a modified installation technique. This is to break the tabs off of the old batteries with small needle nose pliers rather than unsoldering them from the circuit board. This allows the old batteries to be removed but leaves the tabs attached to the circuit board. You can then solder the tabs from the new batteries to the old existing tabs
If you are not able to do this yourself, you can have shaveroutlet.com do it for you. See link below
