There is a way to fix this problem but i ain't easy...
The JX10 has a pretty dumb intelligent charger, it won't charge the battery when it's below a certen voltage so you have to temporarily "boost" the battery for the charger to pick up the charge process again...
You have to open the front cover of the JX10, peel out the battery and remove the tape from the battery to reveal the battery connectors.
When the silver foil plate connectors are visible you have to connect the charger and then connect 3 double A battery's (taped together or something) (total 3.5 volt) with the foil connectors for just 5 seconds. Mind the polarity! When you do this you will see after a couple of seconds the red charging light will lid! When the red light is on, disconnect your home-made "boost battery's" and the charger will charge the battery again!
It's a pretty hard job becouse of the tiny parts but is't worth the try...
And remeber to charge at least every month or you have to do this trick again!

I had the same problem, called support, they told me battery is defective or too old and doesn't accept the charge. Battery in a headset is hardwired and can't be replaced, so the whole thing is trash :(

i have just repaired my bt250 with this problem, i hadn't used it for around 2 years and when i put it on charge just got i flash of blue led. the fix was to "jumpstart it" the headset needs to se some sort of battery voltage to start the charging process, i stripped mine right down but that was just to fiddley. IF YOU DO THIS IT WILL BE ENTIRLEY AT YOUR OWN RISK AND I TAKE NO RESPONSIBILITY IF YOU TRASH YOUR OTHERWISE USELESS HEADSET. ok all you need to do is very carefully remove back cover (undo 1 screw and ease it apart). be very carefull as there are delicate wires inside. lift the inner part out slowly and you will see the battery.it has some orange tape around the end and there is a small circuit board attached to it with a small red wire and a small black wire. look at the battery and you will see under the orange tape there are to larger tags.these are the main battery terminals, peel back the orange tape just until the tags are slightly exposed. now you need to solder a wire to each of them and DON'T TOUCH THEM TOGETHER. on the battery it says which tag is + and which is - make sure you mark your wires or get red and black ones. now i used the lead from the charger. look at it . it has a hole in the center of the pin that is the + so put the + wire in there. if you are not sure use a volt meter. now touch the - wire to the outer metal of the connector that is the - point on the charger connector. hold this for around 2 mins but no more. as the out put of the connector is 6.2v and the battery is only 3.7v the battery will get warm. if the battery is getting too hot in under 2 mins then take of charge. when you have done that and taken off the connector i recommend to use a volt meter and just put it on the battery wires you soldered on to check battery voltage. as long as it reads you should be ok. de solder your wires from the tags and rebuild headset then try and charge it. this worked for me. i am no electronics expert i just like to mess with broken stuff so i know it seems a bit dodgy to connect like this but i had nothing to lose and it worked.
