Question about Philips Philishave HQ7740 Electric Shaver
Yes, there is a battery pack inside that can be changed. You will find replacement batteries for model HQ7740 at shaveroutlet.com. See link below
To replace them, you will need to first remove the flip up lotion cartridge cover on the back. Then remove the 5 screws there to take off the back of the case. You can then access the batteries. You will need to 'unsolder' the old ones from the circuit board and then solder in the new ones.
If you are not equipped to do this yourself, shaveroutlet.com can do it for you. See link below
