18650 down to 3.1v?

[rades]

So I accidentally (I know, stupid) ran an AW 18650 down to 3.1 volts (3.18) to be exact.

Battery is now charging fine, is it good to still use or should I discard it?

I've ran em a hell of a lot lower than that and mine are fine. You're good friend. Recharge it, and continue using it.

2.5v is the cell killing zone, but I have a nitecore charger that has recovered batteries from 2.2v. Only issue I have had after recovering a cell has been cycle life. A good charger will pay for itself so it's worth investing in one. I think I got my 2 bay for 9 bucks at a dirt mall but there are better ones out there.

No worries at all.

I figured! Thanks guys.

I guess I was wondering because I see so many posts saying DONT let your batteries go lower than 3.7!! And I always wondered why re charge that high???

Only thing I can think of battery life in the long run but isn't changing a batt out at 3.7-8 a little excessive?

Yea that's waay excessive to me.

Charging at 3.7 or so means you're only using about half the battery capacity. Overall, it supposedly quadruples your cell recharges, so it doubles cell life (since you're charging at 0.5 capacity).

But that's for optimal cell life, not what the cell can work with--and is designed to work with.

While I generally try to limit usage to 3.7, if I'm out and about and don't want to carry a passel of batteries, they get drained right down until the mod stops working (3.2-ish in my case). The battery is here to serve me, not the other way around. That time, it just has to bear up and deal with it.

As mentioned above, check your specs, but 3.0 is OK on the very vast majority of batteries I've ever seen. 2.5V is OK on many INR batteries. However, at the lowest voltages you should charge your batteries as soon as possible.
