Question about LG Jabra A210 Bluetooth Adapter for Headset
Plugged in new jabra A210...red LED turned on but remained on only 3 seconds. not charging for some reason. any ideas, please?
I had not used my A210 in a couple years, and when I needed it again now, I TOO GOT THIS SAME EXACT SYMPTOM: where it would light red (charging) only for 2 or 3 seconds, and then be off. Hours on the charger and no charging or difference. I tried plugging it in a few hundred times to see if it would "jump start" for the 3 seconds to add up, no luck. I WAS VERY GLAD to read MightyFrosty could change something inside and get it working. I followed his advice up to "removing the tiny circuitboard on the tiny battery and resoldering". Instead (got the case open with a razor blade, gently) I removed the amber tape that wraps the battery/circuitboard assembly and tried first "jumping" the red to the "+", nothing~ but then jumping the black to the "-" the RED LIGHT came on and STAYED ON! (but only while "jumped". Better yet after some 20 minutes of "jumpered" charging, the RED LIGHT STAYED ON even when I removed the tiny jumper~! (a tiny wire is all, bent to touch the black wire solder spot and the "-" battery lead). so IT APPEARS it CAN CHARGE PROPERLY on its own once the battery has a little juice in it! It is charging completely normally now (red light solid, no jumpers, and with no cuts or circuit removals!). I believe I can reassemble it all tomorrow and have a non-modified operational bluetooth Jabra! Thank you MightyFrosty and good luck to all!

I had the same issue. So what I did was get a small screwdriver, opened the A210 case removed the battery. You will notice orange tape (remove it) then attached to the battery is a small board (the defective part) . Cut away the board, then you will need to solder the wires back to the thin metal film leads. And voila it will now charge, make sure to never let it charge for more than 2 hours. Do this at your own risk. Of course this will void the warranty.

They sell replacement batteries on Amazon for about $8

This worked for me as well. I was able to take the jumper off after about 5 minutes and the red light stayed on. After about 40 minutes it would turn on. We'll see how well it holds a charge.
It seems like a really un-smart design, where a dead battery can't be recharged... because it's dead.

Same story. After not using my A210 for years it would not charge. Kev in Cal's advice. I opened the case "carefully" with a razor blade. cut the orange tape off of the battery/overcharge board. made a tiny jumper out of a piece of cut wire. I plugged the charger into the device, held the jumper on the "-" post on the overcharge board and the other end onto the "-" tab of the battery. The Red charge light came on! Held this position for about 4 to 5 minutes. After that time, pulled back my jumper and charging continued. Put the case back together and it's working perfectly. Thanks guys and thanks FixYa site. Great Stuff.

Thanks to all who have posted their solutions. Just to shed some light on this problem, the little circut board in the battery is a overcharge/under charge protection circut By removing the board you can now overcharge the battery and if you do- ?smoke?. The module I have has the battery puffed. that means that the battery is damaged. I got this module to interface with a two-way radio and I plan to power it remotely so I'm removing the battery. This fix is not for the faint at heart and requires soldering fine wires. If you like doing things like this- go for it.
