I'll keep the set anyway because the charger is alone already worth the money and the batteries are good, at least as an emergency reserve.
UPDATE
The seller has here summoned to the commentary on the battery life of your own accord back and replaced with an updated version. That was fast and unbureaucratic and that new batteries are now as the charger TOP.
Conclusion: Great Power Bundle for the RX100 and a seller, how to ask for it - so now instead of 3 full 5 stars.
