I have an old Plantronics CS70 NC wireless headset. The battery is
dying. When I checked the owners manual, I was shocked (Shocked, I say)
to discover that the headset has to be mailed back to Plantronics to
have the battery replaced.

An Internet search turned up several companies that sell replacement
batteries, biut none of them have instructions. The problem is that I
cannot figure out how to open the battery cover. It has a little
Phillips screw, which I removed, but that doesn't seem to hold the cover
on.

There is another round "cap" that appears to require a special tool.
I've uploaded several photos:

https://www.dropbox.com/sh/zs29tax9cflnu42/64Yz3HrNJL

I called Plantronics. The tech told me that that unit is no longer
supported and I need to upgrade to the newer model. I told him that the
device works fine. It's just that the battery is dying. He was not
sympathetic. I asked him if he could suggest a way that I could remove
that cap. He first said that he is not allowed to give out that
information and then that he does not have that information.

One website said that the battery is soldered in place.

This is the last Plantronics product I will ever buy.

I tried grabbing the little edges with needlenose pliers and tweezers.
No joy.

It looks like it is threaded. I'm wondering whether I could epoxy the
head of a Phillips screw to the cap and use that to unscrew it.

Any better ideas?

I don't care too much if I damage it. It's almost useless as it is and
Plantronics will not repair it.

I suspect the headset is considered a replacement part for the system.
It appears to be an expensive system, and probably worth replacing the
headset rather than throwing it away.

My guess is that you are trying to remove the wrong "cover". There is a
replacement battery for a Plantronics CS70 at Amazon. The photo shows a
flat battery, which might not fit through the round area you are trying
to open. You might contact Amazon or Bedford Power, their supplier, to
see if instructions are included.

I would look for a way to remove a side panel of the battery compartment
rather than the end. It might be as simple as sliding a fingernail
along the edge of a plastic panel. The screw you removed may or may not
be involved.

I visited a Plantronics factory many years ago, and was impressed with
their operation. Whatever they lack in customer relations, they make up
for in the quality of their products. I doubt a chinese knock-off would
last as long or work as well.

Well, I'll be damned. You're right. The silver case comes right off. I
just wasn't pulling hard enough.

The battery is indeed soldered in and the connections are pretty small

Yep, I found many of those same places, plus several more. The prices

Good luck, it's a disposable society. Even cell phones are going toward
non replaceable batteries which I totally disagree with, but I doubt the
average consumer will notice. The expected lifespan of the product is
likely shorter than that of the batteries.

Look to see if you if there is a Batteries Plus store near you, a repair

dead rechargeable batteries. He picked up the batteries at a Batteries

Anyone with a soldering iron suitable for electronics should be able to do it
easily. even a larger iron might do it if carefully used. Good luck.

Good point, *but* I'm just saying that if Jennifer is looking to find
small consumer electronics like that where the batteries are supposed to
be user replaceable using only a fingernail and/or jeweler's screwdriver
(and I agree with her that that is what I *want*) she's going to be very
disappointed.

I repair stuff that people toss in the trash all the time. Most of the

wireless N routers, laser and inkjet printers, keyboards, mice and
speakers. I'm using a Dell Precision 390 workstation that was a rescue.

to the charging contacts and pulling the silver plastic case away
from the black frame.

Well, I'll be damned. You're right. The silver case comes right off. I
just wasn't pulling hard enough.

The battery is indeed soldered in and the connections are pretty small
and close together. I think my soldering iron might be too large.

I uploaded a couplew of photos of the connectors:

https://www.dropbox.com/sh/zs29tax9cflnu42/64Yz3HrNJL

Instead of unsoldering the existing soldered connections, maybe you could
cut the existing battery wires off near the existing battery. Then, install
the new battery by connecting the wires from the new battery to the
remaining wires that are still soldered to the device. Twist the wire
connections together and either tape them or, if you want, solder them.
Good luck.

Hmmm... Interesting idea. The wires are tiny and the space is very
cramped. I don't think any kind of screw connectors would fit in there
and ewven take might be too bulky. Plus I'm not sure taping tiny wires
in a tiny space would be easier than soldering. It's been a long time
since I soldered anything, but I think that's the way to go.

But thanks for the creative idea.

Good luck, it's a disposable society. Even cell phones are going
toward non replaceable batteries which I totally disagree with, but I
doubt the average consumer will notice. The expected lifespan of the
product is likely shorter than that of the batteries.


"Non-replaceable" is in the eye of the beholder. It rarely means anything to me,
other that a bit of an obstacle.



Good point, *but* I'm just saying that if Jennifer is looking to find
small consumer electronics like that where the batteries are supposed to
be user replaceable using only a fingernail and/or jeweler's screwdriver
(and I agree with her that that is what I *want*) she's going to be very
disappointed.

But then I am disappointed by a lot of things that aren't the way they
*should* be (IMHO). ;-) I still grumble some.

I didn't say I didn't grumble, whine, and complain about it, just that it was the way it was.

I do go out of my way to find good quality long lasting products whenever I can, but in some cases I've found that it's simply not possible or prohibitively expensive. Some days I think I'm curmudgeonly beyond my years :/

Anyone with a soldering iron suitable for electronics should be able to do it
easily. even a larger iron might do it if carefully used. Good luck.

I got out my old soldering iron. I haven't used it for at least 20
years, probably longer. It isn't as large as I thought it was.

I was able to unsolder the old battery without any problems, but I'm
having trouble soldering the new one in place. The wires are very thin,
which means that they bend easily. I'm having trouble keeping them in
place long enough for me to melt the solder and have it harden. I need a
third hand.

I think I'll go buy a little bench grippers with alligator clips and a
magnifying glass. If I can secure the headset, I might be able to
complete the solder.

But, before I do that, I want to try another option. I noticed that
there are actually little holes in the circuit board where the wires
could go, but they are clogged with solder. The old battery was just
soldered on top. So I guess I also need a solder sucker, unless there is
something around the house that I can use to suck the molten solder out
of those holes. If I can open them up. I can insert the wires and bend
them over on the other side. That would make the soldering job easier
and probably a better connection, as well.

Can anyone suggest a way I can suck up that solder without buying a
solder sucker that I'll never use again? Of course, they are only about
$5.

You can simply melt the solder and blow it out of the hole like you were
blowing out a candle only use more force. You can get an old towel and
use it to prop up the gadget you're working on, hold the wire lead
in one hand the soldering iron in the other then if you have solder on a
spool, have a piece unrolled a bit so it sticks out from the spool then
you can tin the stripped end of the battery lead wire with solder by
touching it and the solder to the iron at the same time. You don't need
more than a tiny amount of solder to tin the short stripped end of the
wire lead. If you have solder in a plastic tube, pull out a few inches
of solder then hold the opposite end of the tube in your teeth like you
would the plastic cap of a ball point pen. Proceed with tinning the
stripped ends of the battery leads. The solder in the stranded wire
makes it stiff enough to hold together so it can be stuck through the
previously cleared hole in the circuit board then bent over enough to
stay in place or with your gadget propped up by folds in the old towel,
melt a bit of solder on the tip of the iron then holding the wire lead
with the fingers of one hand, push the tinned end of the correct
polarity battery battery lead through the hole in the circuit board then
touch the tip of the iron with tiny blob of melted solder to the tinned
lead and printed circuit board where it sticks through at the same time
and the solder will flow off the tip of the iron to to make the
connection. Don't hold the iron on the circuit board for than a second
or you may burn it. Hold the wire steady in place for a few seconds
after melting the solder and the connection will cool enough for you to
let go. I do this kind of stuff without thinking because I've done it
for so many years and even I can screw up so be safe, don't lose focus
and concentrate on what you're doing or you could damage something. I'm
sure there must be a YouTube video on soldering
wires to a circuit board but if you have any questions, don't fail to
ask. ^_^

P.S. I know you can handle it. ^_^

TDD

solder wick is another option, probably will cost at least $5 as well. available at radio shack, so you don't need to mail order. Somewhere around here I do have a solder sucker that works well, if I come across it in the next few days I'll post the brand.

If this is going to be a one time job and you'll never solder again, you could use scraps of stranded wire instead of solder wick if you have any around. Won't work as nicely but if you are only doing two wires, saves you a trip to store and a few bucks.

Strip some solid copper wire slightly smaller than the hole, place it
against the closed up hole, heat it until the solder melts and slide the
wire back and forth through the hole. If it's as small as you say, the
solder will adhere to the wire and will leave it open enough to insert the
battery wires.

I would caution you to use an alligator clip on the battery wire between the
battery and the end of the lead to draw off some of the soldering iron's
heat. You need to keep the battery from getting too hot because it can
easily explode. DAMHIKT!

Yes, I saw some of those online as well.

Aha. Good idea. The molten solder will wick up into the strands, right?
I think I have some around here somewhere. I'll give that a try. Thanks.

If she can find a small piece of coax, the braid shield will also make
pretty decent solder wick. A bit of flux, and good to go.

A solid wire poked through the hole after the pad has been heated,
works too. Keeping the wire cold (heat the pad, not the wire)
prevents the wire from being soldered to the via.

The hole is tiny. There are two other connectors of similar size that
are unused. I was not able to get the top of a standard push pin through
it. Even one of my larger needles is too thick.

I don't think that is a problem. When I was trying to solder it
yesterday, I was holding the battery and the lead wires in my hand. I
didn't feel any heat at all on the leads.

I ended up buying this replacement battery:

I couldn't manage the headset, the battery, the soldering iron, and the
solder with just two hands, so I ordered this "third hand" gizmo:

http://www.amazon.com/gp/product/B00...?ie=UTF8&psc=1

It's not the easiest thing to use, it has no case, and in order to put
it back in the box it came in, I have to take it apart again. But for
$7.35, it's a good deal.

Once I got it set up, the job was done in about 10 minutes. I didn't
even need any additional solder. I was able to melt the little drop that
was already there and attach the new wires. I then reassembled the
headset and charged it up. As far as I can tell, it's working.

Thanks for the help.

Visit our video on how to replace your CS70n battery we carry these
batteries in stock as well and offer a repair service to have it done. A
lot of knock off batteries will work the same as a dying battery, so be
careful.
