Default 3V Fully charged rcr123a battery voltage

Hello, just simple question, what voltage should 3V rcr123a battery have when fully charged? Im charging it with my nitecore d4 and it shows 3,4V and still charging... is it normal?

EDIT: The battery is probably broken... got 2 of same kind and only one of 5 bar was blinking and the charger was showing 3.4V and then stops charging... same happened on both batteries... Other batteries (18650s 3,7V) work fine

Default Re: 3V Fully charged rcr123a battery voltage

Do you have some reason to believe that the Nitecore D4 is capable of charging 3V 16340s ?

Because I don't see anything in its literature to suggest that it can charge that type of false voltage cell. I see Li-Ion, LifePo4, and Ni-Cd / Ni-MH voltages listed. There's nothing to indicate that it can charge those regulated 3V cells.

Chances are that charger interprets your cell as a LifePo4, overcharges it, and damages it.

Just because two batteries have the same size does not mean they have the same chemistry.

It can charge 3.7V 16340's.
