Motorola S9 headset won't charge batteries

S9 Indicator Lights

Mine is doing the exact same thing. Does anyone know what the problem is? If so, what is the fix.

I just had the same issue. I charge my headset every day so I came to the conclusion that the short was due to a small piece of metal shorting out a connector in the chargeing port of the headset. I fixed it by first opening the charging cover and holding the headset by the ears in one hand. I then lightly tapped the opening against my other hand to loosen the metal shard. After doing this a few times, the sound came back. I then used a can of compressed air to finally flush out the intrusive shard. I didn't see how large it was but now my S9-HD headphones work! I'll check the connections on my 2 chargers to see if they have any evidence of breakage because I did notice when I plug in the set, I have to jiggle the connector a little recently.

This is caused by a power surge. To correct, plug your headset into charge, and then plug into power strip. Trip the switch on the power strip to off. It will cause a drain and turn off your green light and then allow the headset to turn back on.

try plugging in the charger to the headset, unplug the charger from the AC. If the light goes out see if the headset will connect.

Worked for me this way

I had the same problem but instead of a red light it would flash green twice and stay off. I could not find the original charger and another plug in charger would not work. I plugged it into my computer with a usb cable and after several seconds it started charging.

If you guys haven't found a solution, you might want to try this out. Have your S9 charger hooked up to the unit and plug the charger into a surge protector. Flick the main switch of the surge protector on and off a few times and it should turn off the unit. Then turn on and pair if need to and it should be fine. Hope that works for ya!

The diagnostic procedures from the Dell User Guide are as follows:

Total Power Failure When Using a Battery
If an AC adapter is not connected to your computer, the computer's power source
is a battery. If the battery indicator flashes amber or is a steady amber, the
battery needs to be charged. If the battery is flashing green and amber, the
battery may be defective. To troubleshoot this problem, use the following
procedure.
1. Turn off the computer and peripherals, and disconnect them from AC power.
2. Reseat each installed battery by removing it and then replacing it.
3. Turn on the computer. Does the green power indicator light up?
Allow one minute for the computer to initialize its components before checking
for signs of power.
Yes. Continue to step 4.
No. Use the AC adapter to connect your computer to AC power. If the computer
operates normally when using AC power, go to step 7. If the computer does not
boot when using the AC adapter, see the previous subsection, "Total Power
Failure When Using the AC Adapter."
4. Does the battery indicator flash amber or show a a steady amber light?
Yes. The battery needs to be charged. Go step 5.
No. Go to step 7.
5. Connect the computer to AC power, and fully charge the battery.
For instructions, see the topic titled "Charging the Battery" in the online
System User's Guide.
6. As the battery charges, does the green battery indicator light up?
Yes. Go to step 9.
No. Go to step 7.
7. Is the battery indicator flashing green and amber?
Yes. Your computer may be in a hot environment. Charging the battery in this
condition may affect the life span of the battery. Continue to step 8.
No. The problem is resolved.
8. Disconnect the computer from AC power. Is the the battery indicator still
flashing amber?
Yes. You may have a defective battery. Continue to step 9.
No. The problem is resolved.
9. Remove the battery, and press its test button. Is the uppermost indicator in
the charge gauge of the battery flashing?
Yes. You have a defective battery. Continue to step 9.
No. The problem is resolved.
10. If a spare battery is available, fully charge it, and then install it in the
computer.
11. Turn on the computer. Is the power indicator off?
Yes. Your original battery is defective


good luck

I had the same problem with a Samsung phone. There are two ways of fixing this; First, you can remove the S9 profile from your phone's bluetooth list, and then add it again, going through pairing and entering 0000 on your phone when asked for the code.
Alternatively, you might try pressing the "play" button on the right earpiece on the Motorola S9. This is supposed to kick it into the A2DP stereo mode for music listening.
Good luck.
And get a copy of the manual from the Motorola web site at http://direct.motorola.com/ens/s9/Headset_Home.asp I found this very handy for checking what the little flashing lights mean. When you get stereo reception, the little LED in the middle of the headset flashes green, not the usual blue and red and purple for voice calls. 
In case you didn't know, as a phone headset, with the microphone activated, you only get sound in your left ear, and the light flashes blue. For music, you get both ears, and it flashes green. So if it ain't green, you are in mono mode.

I just hooked it up with a usb sync cable to my computer. It was installed and ready to use and the charging light came on. Seems like it is charging as the led went from red to yellow, and it does turn on now. However, it still does not work with the usb cable plugged into a wall charger. If this solution works for others having the same issue kindly post your results.
