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

Re Phillishave HQ7780 Why does battery fail completely when switched off at the end of each shave and then has to be recharged before it will operate again.


It sounds like the battery no longer holds a charge correctly and needs to be replaced. You will find replacement batteries at shaveroutlet.com. See link below. Also, scroll down the page for helpful videos to aid in installation

My Philishave HQ5620 charger is kicking out 5.8V(ac), but my shaver fails to charge up. Any ideas why?


After a couple of years the battery may no longer hold a charge and need replacement.

Charged for approx. 6 hours then wouldn't work


I copied this from the Philips website... this took me FOREVER to find! Their site isn't the easiest to find products on...

"Insert the small plug into the shaver and put the powerplug in the wall socket. When you charge the appliance for the first time or after a long period of disuse, let the shaver charge for at least 16 hours. Remove the powerplug from the socket and the small plug from the shaver as soon as the batteries have been fully charged. Ignore the charge indicator when you charge the batteries for the first time. The batteries are completely new and need to be charged longer than the time indicated by the charge indicator to ensure that the back-up capacity is fully charged as well."

I hope this helps. Please remember to rate my help! I would greatly appreciate it!

Have a Braun series 8000 shaver battery not charging


Well if it's not charging at all and you are not getting any lights, then you could have one of two issues. Either you have a bad power cord or PCB board. If it's just not holding a charge then you can replace the Batteries.
