Note: most shavers will require soldering to the circuit board – you will need the right tools and expertise to install this pack. Simple instructions included with the packing slip to ease installation. Replacing the battery alone may not fix the problem – if the shaver indicator lights do not come on, the circuit board may be defective and the shaver may require replacement.
