We heard recently about a lot of incidents implying chinese made CR123A. Did accidents happened with Li-Ion, except the one who charged one that exploded with the 7.4V charger setting instead of the 3.7V one?
Did incidents happened with Li-Ion?

li-ion are rechargeable batteries.

I think you mean the incident in this thread where a universal charger was incorrectly set to 8.4v instead of 4.2v for a single cell.
Yes, there have been numerous incidents where Li-Ions have blown up, mostly during recharging. This thread would be a good place to start reading about how this can happen.

Hi WildChild,
Maybe better if asked like this.Are there any reports of protected Li-Ions exploding inside a flashlight while running at manufacturers spec? Not that I'm aware of.

I didn't specified "inside a flashlight" because I wanted to know in general, within the CPF community.

There's a bunch of Li-Ion vent with flame incidents in laptop computers and cell phones.

I already know about that! It's more to get a radio of accidents, primaries vs rechargeables... We heard a lot of accidents with CR123A made in China, not many with Li-Ion.
To answer you directly, not as many with Li-Ions such as the ones from AW, as with disposables (especially from cheap Chinese types).
Keep in mind that we are a relatively small use community, and relative to the RC community, and tens of millions of laptop/cell phone users, it is hard to get a large enough sample size where these events show up.
I think part of the lower incidence of Li-Ions is also related to the relatively low charging currents we tend to use with the various chargers that have been promoted on this forum. Add to that, safe chargers such as the Pila, balance chargers, repeated warnings to be careful, and discussing more risky type chargers....all of these factors tend to improve the outcome.
I believe AW does a great job of supplying safer cells and especially his protected cells, which are likely the most used brands of Li-Ion cells in this CPF community. We have seen evidence in various threads that there are a number of people who never report their accidents, and maybe mention it as a part of an unrelated thread as a "by the way..."
Remember that the Laptop battery packs use individual Li-Ion cells that are wired in parallel/series...so that example is relevant.
