901 Riva-Did they change things up? Are they safe and protected?

I just got a bulk shipment of Riva 901 batteries. I haven't order any for a while so am not sure why these are different. The batteries have a pin hole in the center of the post where you connect the atomizer. Looks just like the pinhole on the connector end of the atomizer. Is this thing going to leak?
Also when I put it on the charger the light on the battery blinks and then it stays blue. I'm not sure what's going on. Anyone have any thoughts on this? So far 9 of them are doing this. I'm having everyone check theirs.

This may or may not have bearing. Got Riva 510s recently. No change on charge light. (i.e. blinks then goes dark) from previous. Have an older Riva 901 - blinks at start of charging and then goes dark like the 510s. Did note for first time that even though the Riva 510s have an engraved "Riva" just above the male threads - the Riva 901 does not. Pin hole in center connector, presuming it goes all the way through, does not sound positive to me. Circuit board just below that center connector on 510s and likely same on 901s.

I agree about the pinhole. I'm keeping them and using them mainly because of the cost to ship them back. I'll let you know if they blow up on me!
