Question about Philips Philishave HQ5812 Electric Shaver

1 Answer

The chargeable batteries in my trusty philishave 5830 have been running down gradually. Lately, the shaver got quite hot when a plugged it in for a re-charge. Now, suddenly, it will not charge at all, so I can use teh shaver even when plugged in to the mains supply. Will this problem be fixed simply by replacing the batteries, or is the problem likely to be in the electronic bits that manage the changing, or maybe even is it the transformer that overheated?

It is impossible for me to say for sure without actually looking at it but the problem is, most likely, the battery. Changing it will probably fix the problem.
Take a look at the circuit boeard for corrosion or burnt spots. If you see neither of these, I would say that there is a 98% chance that only the battery needs changed

I have a philishave hq 6849 which is about 5 years old. I charged it yesterday and today it is "dead" when I plug it in the mains the greenlight comes on but nothing else happens. Is there an internal...

Yes, there is an internal battery and it can be replaced. You will find the battery you need at See link below
You will need one or two batteries depending on the internal configuration of your model.

To open the shaver, you will need to remove the two screws on the back of the shaver. Once the back cover is removed, you will be able to access the battery pack and circuit board. You will need to unsolder the old battery pack from the circuit board and solder in the new one

Mains shaver , speed of a battery one which is running down and no power!

solved the problem with the shaver, PhilipsHQ7300, "mains washable" took it back and went back to old ones, which when you use them seem to have the power to shave you and not sound like they are running on low battery, which as they are mains I cant understand alright they are reduced to 24 volts(for safety purposes if you wash them plugged in) but a cordless 18 volt drill sounds more powerful than the shaver I know they are 2 different things but surely a shaver should shave smooth and quick, I know things are progressing fast and the great selling point is for products "look how much time you save" but this shaver is not up to par with the older models and it certainly does not save time, so as we no longer have this item we have solved the problem thankyou

Philips shaver not charging

The batteries are soldered to the circuit board with solder tabs. These are not standard chargeable batteries that can be bought at the corner hardware store. The are Lithium Oxide based batteries with solder tabs. These should be replaced by an experienced tech. The replacement batteries must be to spec of the original ones. There is the current rating and voltage rating of the batteries to matched.

Because these chargeable batteries can put out a strong amount of current, if they are not installed properly, there can be safety issues.

Call Philips tech support to be advised about where you can take the shaver to have the batteries changed.
