How to "wake-up" my "dead" LiIon battery?

[petar k]

...i undercharged one of my 10440 protected batteries. when PCB is on the +, it shows no voltage. when i try it without PCB connected to the +, it shows around 1,7V. i try to recharge the battery, but it shows "green light" as it is fully charged - it's not. i try to charge the battery with and without PCB - the same.
so, what should i do to "wake-up" my seemingly dead battery? (i need it a lot)

Dispose of the battery. Get a new one.

i red on some sites that there is some way to wake up LiIon batteries (but for lap-tops) it says something about freezing a battery and than recharging it. but, i'm not sure about batteries that we use.
also it happened to me that my PV just stop working after some serious discharge, but when i plug it to recharger, it charges and work normally. (not this time:-(

It should be easier to get a new one.

If you get five posts, and wait an hour for the forum to update, you will be able to post outside of the New Members forum.

I think you will get a lot of expert help on batteries in the Battery Mods subforum...

If it's down to 1.7v even if you could revive it, it's probably already damaged to a certain extent that you can never get back. Get a new one.

the problem is that i have no second PV to vape. i have already ordered two batteries, but, it's weekend and Easter is coming, so postal offices doesn't work here until Tuesday. so, i'm desperate to bring this battery to life.

What charger are you using?
If it is a multi-volt charger it can bug out thinking that a li-ion is of a different chemistry.

Do not, NEVER freeze a Li-ion. Freezing and heating batteries is a trick that coems from Ni-cad batteries. Ni-cad batteries will crystallize over time. This is that "memory effect" that you often read about. Thermal shock can remove the crystallization on occasion. Thermal shock however is bad for Lithium batteries.

With out more knowledge, either your battery is dead, or you have a charger problem.

Why do you say that?

I've been storing my batteries in the freezer since day one...

yeah i worked for energizer for a few years as a battery tech... DC2 Li-Ion and Li-po batteries are extremely cold sensitive this should never be done. its the same reason that the jets i work with now have a heated blanket around their Li-Ion and Ni-Cad batteries for flight at high altitude

thnx for the effort, guys. just to say that i removed PCB and the batt is working now.
btw, the batt was in frizer for around 1h at -5C, however, i'm using it now
