Query: NOT the same as the Panasonic fellas...

Hey guys,These batteries are NOT the same quality as the Panasonic factory batteries. In the field the HVX220AP's we use can last about 2-3X longer on the Panasonic battery than these guys.Also irritating is the battery drain (decay time frame) itself. With the Panasonic, it's a fairly even drain, so you can look at the indicator in the viewer and what the battery says it has it has.With these, you go from FULL to EMPTY pretty fast, the drain during the lower battery life is faster than the Panasonic.They were an interesting alternative, but I don't use them anymore if I can just use the Panasonic's.
