IMR + Nano Charger- only 4.0 V?

[GarageBoy]

So I'm using this charger til the light turns green and my 123 size IMRs are only 4.0V. Is this remotely full?

Not so much. Consensus seems to be 4.1V to 4.2V is full. If it's any comfort, you are marginally extending the life of the cells by not charging them up to 4.2V. I'd be a little dissatisfied by 4.0V, though.

I *believe* the Nano trickle chargers to 4.2V and possibly higher after the light turns green. Might want to do a search, I'm a little fuzzy on that fact. Try leaving them on the charger for 15 minutes after it turns green and measure then.

IIRC, there were two versions of the 123 Nano charger. One was for 3.6/3.7V LiIon and another for 3.0V. Has it properly charged other LiIon to 4.2V?

Yup, used it with other cells before

In AW's sales thread he lists the following:
LiIon Battery Charge Status

4.2V – 100%
4.1V – 87%
4.0V – 75%
3.9V – 55%
3.8V – 30%
3.5V – 0%

So 4.0V is about 75% or there abouts. I would presume that the list is an approximate guide only.
