Hello

Remove the electrical cord from the base of the shaver.

Press down and slide off the panel on the front of the shaver.

Remove the two nickel-plated batteries. Use these batteries as a guide to purchase new batteries at a hardware store or home repair store. Recycle the old batteries when finished. (Many hardware and home repair stores have battery-recycling stations.)

Put the new batteries inside the shaver and press gently to pop into place.

Place the front panel back on the shaver and plug the electrical cord into the bottom of the shaver. Connect to an electrical outlet to charge.

To open shaver, first remove the two round or oval screw covers on the bottom of the shaver. Then remove the screws underneath, The can then slide the outer case of the shaver down and off of the shaver inner body exposing the batteries

To replace, you will need to gently pry off the cap that surrounds the cord hle on the bottom. Once removed, the side grips will pull away easily revealing 4 screws on the back. Remove screws to take the bask of case off and then lift out the 'guts'. Reassemble in reverse order

I believe that you are stating that your model 4775 Braun shaver no longer holds a charge. To repair this you will need to replace the batteries. To replace the batteries, you will need to open the shaver up. First, remove the two round plastic screw covers on the bottom of the shaver then remove the screws that are underneath. The outer casing will then slide off the bottom of the shaver. You will then be able to access the batteries.

In your case, it's hard to know exactly what might be wrong without more information. Was the shaver perfectly fine and then all of the sudden won't turn on? Or was the shaver working for shorter and shorter periods over time and then just quit? Was it exposed to undue heat, such as left in a car or in a place that wasn't air conditioned in the hot summer?

Although the batteries in these shavers are fairly robust, if fully discharged and not used for a long while, it might be that they've got a "low level memory" and will need replacing. If you are handy, you could disassemble the shaver and replace the batteries. They are NiMh AA flat top batteries that you can buy on websites like onlybatteries.com. If you're handing with soldering, you can replace them yourself. If you're unsure about that, you can buy the batteries along with the circuit board as a complete unit that drops right into place. Shaveroutlet.com sells these.

Another thing is that if the shaver was dropped, there's a chance that a metal connector part has come loose and so the shaver won't function. Taking it apart, you can see if this is the case.

The Braun 7000 series are rather old at this point, so sending it off for repair is kind of out of the question, as the costs involved would be more than if you bought another shaver. If you're not wanting to spend the big $$ on the new 9000 series shavers, find a new old stock 8000 series shaver (they are better made than the 7000 series). You can search on "that auction site" and you'll find quite a few Braun 8000 (or 360) series shavers available for sale.

Since I have never dissembled this model ask Shaver Outlet via e-mail if you buy the parts from them. They have been most helpful to me.

Open the shaver:
1) Use a small flat screw driver pry off the bottom (where the cord plugs in)
2) Remove the silver sides
3) Using a small torq driver remove the 4 scews
4) Open shaver
5) Remove circuit board with batteries
6) Remove and replace circuit board with batteries (or solder in the new batteries)
