Hello,
I've got a JVC GR-DF420EK Camcorder and I'm looking for a BN-VF733U
battery. I've found the original from JVC costs £95! and the cheapest
from ebay a non-JVC battery costs £22 incl. delivery from Hong Kong.
The manual states non-JVC batteries can cause damage to the internal
charging circuitry. Has anyone used these cheap generic batteries in
JVC camcorders that use the new data batteries and what was the
result? Thanks.

I can't speak for JVC, but I've been using clone batteries for my Sony
for three years with no ill effects.
