SOURCE: Communication error?!
I'm betting you bought an aftermarket battery and not an original JVC battery. The error message you are getting is caused by the camcorder not being able to read the charge sensor in the battery. Some of the aftermarket batteries neglect to put that sensor in the battery, or have a sensor which does not match the OEM sensor in a factory battery. Try an original JVC battery. Is this solution answered your question bu sure to rate it. Thanks!

it is good to fully discharge once in a month but dont make it ur habit
pls rate me FIXYA for help
it seems you have a dud battery. you can get cheep ones on ebay . and having spare batteries is always good.
you may wish to check if your battery has a charge if you know some one with a mulitmeter .
see if you camera turns on with a mains power adapter if you have one

Even though the camera shows that the battery is charged it could still be that the battery is faulty. If you don't want the needless expense of buying a new battery just to find the fault is with the camera after all, try rigging up a test circuit with a piece of wire and a low voltage light bulb from a torch or fairy lights. If the bulb lights up then the battery should be OK. (Make sure the bulb works with another normal 9v battery you know is good.)
I just tried this with my camera battery and an old dud battery I had to scrap and the bulb lights up with the good battery as expected.
