    The explosive problem with recycling ... they literally catch fire

    They don't need to be much (if any) thicker to have replaceable batteries. The primary reason they stopped using replaceable batteries is because that forces most users to buy a new model when the battery dies, hence helps to increase profit (also Apple's longstanding closed-system and...

    Death by charging Li-ion battery explosion

    Re: Death by charging AA battery explosion ^^^ Yes, people do mistakenly charge primary cells. But also Li-ion cells can explode while charging. Without any further details we can only speculate which is more likely. Hopefully they'll release more details so that we can learn something from...

    Death by charging Li-ion battery explosion

    Re: Death by charging AA battery explosion News articles claim that the explosion occurred in a "Solar technology" company, so the employee might have been a techie, so possibly more informed about Li-ion safety than a random layperson, i.e. less likely to make such a novice mistake.

    Death by charging Li-ion battery explosion

    Re: Death by charging AA battery explosion @markr6 Yes, that's the same as the article I linked in the original post from AP. Perhaps the cops remark "the kind used in small electronic devices such as radios" was meant to distinguish the cells from more common NiMh AAs (and something may have...

    Death by charging Li-ion battery explosion

    Re: Death by charging AA battery explosion That would certainly be more likely. Could you please give a link, since the Google search I did when I originally posted this thread still fails to find any mention of Lithium or Li-ion batteries in reports on this incident.

    Death by charging Li-ion battery explosion

    Sadly, a German man was killed yesterday by projectile fired into his chest from “a regular charger for two AA batteries”. A reminder that even "regular" battery charging can sometimes be dangerous. There is not yet any further info on the make/model of the batteries or charger. Update...

    Significant 4XAA Battery short in Fenix headlamp

    ^^^ But we don't know if the reviewers were using alkalines. If - as surmised - the electronics shorted the cells then the meltdown may be worse using cells like NiMH with higher current capability (depending on quality, i.e. design of venting, etc). Worth mention is that Fenix ships the HP25...

    Significant 4XAA Battery short in Fenix headlamp

    Yes, such meltdowns have happened to many others, e.g. from Amazon reviews And in a comment on the above review: And another Amazon reviewer wrote And another and another I recommend that you report dangerous products like this to the CPSC = Consumer Products Safety Commission via the...

    Powerbank catches fire, put out with orange juice

    Most generic powerbanks leave much to be desired in terms of safety, so you should be wary of leaving them charging unattended.

    Powerbank charging phone catches fire on plane

    Agreed, from the video it is clearly the powerbank that's on fire, not the phone. Many powerbanks leave much to be desired regarding safety (e.g. lack of thermal monitoring) so one should be careful using them.

    Tesla crash battery reignites 6 days later in tow yard

    Re: Tesla crash battery reignites 6 days later in two yard Did someone claim that "is the main problem"? As I said in the OP, I posted it here because it is an instructive example of risks associated with damaged cells.

    Tesla crash battery reignites 6 days later in tow yard

    There are recent news reports that a battery from a Tesla crash has reignited multiple times while in a tow yard, e.g. It's not clear what caused the reignitions - possibly internal shorts festering due to the prior mechanical and thermal stress. This is worth keeping in mind when dealing...

    SAFEST low discharge voltage for high drain unprotected 18650s?

    Yes, that 2017 RIT Thesis is among the first few matches in the search I suggested so it's a logical place to start, i.e. Enhancing Near Zero Volt Storage Tolerance of Lithium-ion Batteries, by Kyle R. Crompton. The lowest safe voltage will depend on many parameters. The conservative ballpark...

    SAFEST low discharge voltage for high drain unprotected 18650s?

    No, there is both theory and experimental data proving that near zero-volt overdischarges are generally unsafe. The theory reveals the precise voltage where copper will start dissolving and the data shows the damage it can cause (dendrites, etc). Many of these studies are old (before many...

    SAFEST low discharge voltage for high drain unprotected 18650s?

    To clarify: there is no known data proving that it is safe to continue to use Li-ion cells that have been discharged down to 0V. Most likely it will be very risky to do so with most cells available at the consumer level. For further info see the discussion following this post.

    Man bites iPhone battery and it explodes

    You'd think by now we'd have heard all of the foolish ways that people can abuse Li-ion batteries. But no - foolishness has no bounds. Below we have a runner-up for a Darwin award for the most foolish Apple bite (or most explosive Apple logo performance?) A recent news report shows an explosion...

    Safe Battery Charging Bag - didn't know this existed

    No, in theory and in practice, e.g. there are hundreds of pages of international safety standards for laptop batteries, and rigorous safety testing using industry standard methods (fault-tree analysis, FMEA, etc). None of this exists for standalone universal chargers.

    Safe Battery Charging Bag - didn't know this existed

    But there is much more than just protection circuits. Cellphone, tablets, and laptops generally have far more safe battery subsystems than devices that use external universal Li-ion chargers. The safety of universal chargers is limited by the fact that they know nothing about the cell - such as...

    Safe Battery Charging Bag - didn't know this existed

    No, they were used in the RC world long before "hover boards" existed.

    Fire on JetBlue plane

    That's only one of many possibilities. For example, some charger component may have burned, causing the melting on the wall of the charger, and that could have shorted out the cell. Or the cell (while in the charger) could have vented and ignited other items in the backpack which melted parts...
