Product is OK but no battery level or auto turn off on Lumix GH2 and less mAh than original. So whatever that info chip is supposed to be, it doesn't work for me. Still probably OK for the price. Bought these to replace a couple of other third party batteries that were disappointing in that they by now don't hold any charge anymore after only two years while the original battery is still going strong. I think I will invest into another original Panasonic battery the next time, despite the reduculouse prices. I just hope this battery will be better in holding its charge than my other third party batts.
