How to change the batteries in a Braun 7505 Synchro Shaver

[theoldwolf]

People who write instructions for how to do things when they have no clue should be dipped in bees. The instructions here are totally useless, and incorrect.

What is needed are instructions on how to open the battery cover. Which, by the way, is *not* found in the referenced manual. This shaver looks like a monolithic block, and it's plain Braun never intended users to be able to replace the battery. However, it can be done if you are good with a soldering iron.

1) Carefully remove the small cap covering the charging socket with a small screwdriver. There are four catches, one at each corner, which can be gently pushed in.

2) Remove the two decorative side-plates. These uncover the main body screws.

3) Unscrew the four body screws with a small star-drive.

4) At this point you can remove the battery assembly, which consists of two batteries soldered to a small circuit board. You can also remove the main shaver assembly, and might as well gently clean everything while you're at it, using the head-cleaning brush that came with your shaver. It's probably very dusty.

5) You will need to carefully de-solder the batteries from the thin contacts, replace them (if you can figure out exactly what kind of batteries are needed) and re-solder them in.

6) Replace the battery assembly and re-assemble the shaver.

Thanks for nothing, eHow. The same goes for Yahoo Answers, most of which are written by morons. I weep for our world...

The question is, what is the build standard of the razor you have? Have they used the same or similar model number for different shavers?
and
Did they modify the shaver to give it an easily changeable NiMH AA cell after getting a raft of complaints from folks with your (earlier) version?
For preference always have soldered contacts or GOLD yes GOLD contacts for rechargeables. The ordinary plated steel contacts in cheap battery boxes tarnish and the charging becomes problematic.
Me, I use Tesco wet shave disposables.... if you know how to clean 'em you can get a week from each.

I want a shave, not a self-sacrifice. Does the term "bleeding at every pore" have any meaning for you?



(Glad you can use 'em, though)

You mean you don't want the stigmata every time you shave? *EG*

I get that from electric razors. Blades are NOT my friend.

I've got a Norelco with a shot battery. It says it has a 36 minute charge, but it really only lasts about 1 minute, which is enough to de-whisker one jawline. Know where I can find useful instructions for that?

I suppose there's little way you can reengineer it to avoid soldering the batteries in place?
(personally, I could live with the difficult battery-unit removal, but not the soldering part)
