How do you replace the battery in a Braun Electric Razor model 5567U (or anything close to this model)?
Is it even possible?

See instructable here or a generic way to replace the battery in a Braun shaver.

Your model may be somewhat different so you'll need to be adaptable and handy. The replacement battery can be the same type if it was a NiCd or you should be able to use a NiMH replacement of the same voltage and either the same size or a little bit smaller than the original battery. A NiCd charger typically will work with NiMH (it may not work with Lithium Ion batteries). If there's a void to fill, you can use hot melt glue or wrap it with electrical tape or something else of your choosing. If parts won't stay together, hot melt glue may come to the rescue. If you won't ever be replacing the battery again you can use epoxy or some other glue. Hot melt glue can usually be cut off or pried off things but works well until you use a bit of force to take it off, so it's a great adhesive.

Why is there no red light when it is plugged in?

You probably need to replace the rechargeable batteries. The batteries work in series with the shaver... if just one is completely no good in the battery pack, the shaver won't work. NimH batteries only last 2 to 3 years at best; older NiCd batteries far less. All rechargable batteries are made by either Matshushita (Panasonic) or Energizer (old Sanyo brand and before that the GE brand). Some mfrs build their own battery packs using rechargable batteries with TABS from these battery mfrs and wire them together end to end + to -, etc, like a flashlight (torch UK) to make the proper voltage. A Norelco brand is the same as a Phillips shaver.

How to remove rechargeable battery for norelco 7864

hi minglim, welocme to the forum!
    Replacing a Norelco Shaver Battery Things You'll Need:Torx screwdriver set Rechargeable Ni-Cd AA battery 1)Slide up the sideburns trimmer on the shaver .2)Try the various torx head screwdriver sizes to find the fit for the two screws holding the top of the back shaver cover on. Unscrew the two screws that are under the sideburns trimmer that hold the back of the shaver on. On some Norelco shavers, the back will now slide off if you apply downward pressure on the shaver's back. Other Norelco shavers have one or two torx screws on the base of the back cover on the shaver; if so, unscrew them also. Place the screws in a safe place. 3)Take the back cover off the shaver. Some shavers may have a strap fastening the battery down. Unfasten the strap if there is one. Take out the battery. 4)Replace the old battery with a new rechargeable Ni-Cd AA battery. Re-fasten the battery holding strap if there was one. 5)Replace the back shaver cover and re-screw in all the torx screws,

My razor appears to have died even though the LED

Usually the batteries last only a few years before needing replacement. Rechargeable batteries are good for only so many cycles so you've done well to go 8 years. You can replace the batteries if you're handy with a soldering iron - I've done it many times. However, with 8 years on the clock you'll probably want to replace the blades too. The batteries are about $10 for the pair (AA rechargeables with solder tabs) and the blade set is about $30 so you're approaching the cost of a new shaver already. Here's a link - you'll need two.

Battery won't hold its charge, could I get them replaced? Could I replace them myself? If so, with what type of battery?

Rechargeable shavers use either a NiCad or NiMd batteries.

In order to get the correct battery, you need to check your shaver model number and check the following link to see which your shaver uses.

You can buy it from them or find them elsewhere, if you wish.

You can do the repair yourself if you can disassemble the shaver case, which is usually held together with a couple of screws normally hidden behind plastic caps.

Then once the shaver covers are off, you can unsolder the old batteries and replace and resolder the new one in. You'll need a decent soldering iron to accomplish this.

When done, put the case back together and allow it to charge for a good 8 hours before using. It typically takes a few recharges to get the batteries able to hold a full charge, but you should be good after a week of use.

Hope you find this Very Helpful and best regards!

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)

Hope you find this Very Helpful and best regards!

My trusty,beloved rechargeable travel Braun Precision 150 shaver battery is dying. Can the whole shaver be replaced, or can I get a new battery installed. John Boland Kennewick,...

With a little bit of skill and patience, you can replace the rechargeable battery in your Braun shaver for less than $12.00 or so (w S&H included). I've replaced mine twice over the past 10 years (and the foil) and it's still running great.

You can order the replacement rechargeable battery online, I've used Electric Shaver Service in Nebraska for getting parts I needed.

If you want to buy a new one, try as they have your beloved model for $50.00

If you decide to do the battery replacement yourself, you'll have to be able to unsolder the old battery from the circuit board and resolder the new battery back onto it, once you open up the shaver.

Hope you find this Very Helpful and best regards!
