Has anyone used one of these for the everio? Looks like you have to hook some cable into the CC...May be ok for the money though???

Yes I bought a V714 1400mAH generic battery from Amazon UK and it works fine.
Beware only buy from a reputable source as some batteries do not allow the camera software to check the remaining capacity. I had to return one to another retailer.

I would always use a genuine battery, as most of the 3rd party batteries do not allow you to see how much time you have left, and because they plug direct in to DC the camera thinks you're running off direct current, and will allow you to do things you should do unless you're plugged in to the wall, which may damage your camera if the battery dies during the process.
Also keep in mind using a 3rd party battery does void your warranty. I wouldn't take the risk for a few bucks... the JVC batteries are pretty well priced anyway i think, compared to Sony or something.

Could you explain that so an engineer with some power supply design experience or an experienced electronics hobbyist would understand what you are saying?

I'm not sure what was hard to understand...

If you're burning a DVD using the Share station with the power plugged in to the wall, and then whilst it's burning you rip out the plug, it is likley that it may damage your hard drive, you could loose all of your footage.
The camera does not allow you to burn DVD's using jsut the battery, it requirees that you plug it in to the wall so that the loss of power is reduced.

Now if you have a battery that is plagged in to the DC port, the camera actually thinks it is getting a constant feed of power [as it would from the wall] however, if the battery dies whilst you're transfering images or something, it will instantly cut power and you may loose data.

I'm not an electonic engineer, so I can't tell you how the electronics of the battery really work, i have a basic understanding of it.

Hope that clears it up for you.

Righty is correct. Most non-OEM batteries for JVC camcorders are sold with a DC dongle to feed power to DC input. They are not recognized by the camera. I think I saw some more expensive batteries that are recognized, guess their manufacturers have cracked JVC handshake protocol.

Sony uses proprietary media and accessory shoe, Canon switched to a proprietary shoe too, JVC uses standard accessory shoe and mic input, but uses proprietary batteries and proprietary DC input socket/jack. Seems that JVC is the smartest: one can stick a microSD card into a Memory Stick adapter, or buy a $20 adapter for a shoe, but battery market seems to be pretty well covered by JVC.

Unplugging any device while it is operating is generally not a good idea. I suppose your hard drive could be damaged. I do not believe There could be a variety of circuits which could be damaged. Not using an OEM battery is not the problem here.

Yes, you may loose data under these conditions and you may not. But again, this is not because of using an non-OEM battery. Any battery is subject to fail at any time.

The original thread topic is "non oem Battery Replacement". It appears that you do not believe that Non-OEM batteries should not be used, which is ok. You you seem to be trying to instill some fear into peoples minds on the issue with no real credible and verifiable information. It has been a major issue with the Sony "InfoLithium" batteries http://www.camcorderinfo.com/bbs/t106339.html however I have not noticed non OEM battery pack issues in the other camcorders.

Everyone is welcome to try it for themselves, however, all I can do is post my opinion on the matter and I would not recommend using anything other than a genuine JVC battery.
Simply for the fact that it voids your warranty if nothing more.

I thought my reply answered the original question.

I have been using my non OEM battery for 18 months now with no problems as it has more capacity than the one supplied with the camera, that one being kept as a reserve.

As regards the battery failing during downloading from the camera to a PC I always plug the mains power pack into the camera before downloading etc.

If you are using a non oem battery, or even an original battery after all, and it is exhausted while you are actually filming, can it cause damage or corrupt any files?


Thanks

I have never allowed a battery to become completely exhausted whilst shooting (I always connect the power pack when downloading to a PC), but I assume any clip being shot would be corrupted. I cannot say whether all the other clips on the HD would also be corrupted.
If this did happen it should not be completely disastrous, you should be able to reformat the HD.
