NICE translation! (well I am referring to the fact that there IS another translation made I cant read it lol)
This topic cold become a real life saver!
IMNERHO, Google Translate is one of the few Good Things Google provides. Itâs not reliable on its own, though, so I always take the first translation, Copy it to the clipboard & start over translating it back into English (or whatever my first language happens to be). It sometimes takes a lot of work, but the end result is exactly what I first said in English. I do this out of respect for my non-English-speaking friends, but it seems Very Useful here too.
As you can see, theyâre getting a little-bit better:
Dans ma mĂȘme pas Ă distance humble avis, Google Translate est lâune des rares bonnes choses Google fournit. Il est pas fiable sur son propre, cependant, alors je prends toujours la premiĂšre traduction, le copier dans le presse-papiers et recommencer le traduire vers lâanglais (ou quelle que soit ma premiĂšre langue arrive Ă ĂȘtre). Il faut parfois beaucoup de travail, mais le rĂ©sultat final est exactement ce que je a dit dâabord en anglais. Je le fais par respect pour mes amis non-anglophones, mais il semble trĂšs utile ici aussi.
Yes google translate is a very usefull tool!
my reason for hoping it gets translated in as many languages as possible is however so that native speakers who google for li ion safety in their own languages can find it (and then use google translate for the rest of BLF ;))

âIt is not safe to eat Lithium-Ion batteries.â
Fantastic post.
Also,
Not even with ketchup? It makes everything taste good
Just kidding of course and youâd think it would go without saying until somebody does it and then cries ânobody warned me about that!â I hate whining
Iâd rather have it said, although something in me wants Darwin to fix that little problem instead- anyone whoâd willingly ingest any cell or battery does not deserve to exist.

I was debating putting a â â on that lineâŠâŠ
Iâd suggest deleting that particular item. By stating the obvious, it tends to cheapen the integrity of the lesson as a whole. Not to mention adding one more line to an already long message.

I lolled the first time when I read it, but then it hit me there are a lot of scenarios this could be useful (say a dog) to know to get proper help.

Good point.
If anything, further emphasis could be put on not ingesting lithium ion batteries with specific reference to children and pets.
What about LiFePO4? Should we have some info in the OP about that? It is a lot different chemistry, with a different nominal voltage as well as terminal charge voltage requirement. I know we donât talk much about them here at BLF, because theyâre not used in most of the flashlights we buy/build. But, maybe at least just the specifications and a few of the ways they are different from other Li-Ion cell chemistries should be noted somehow in the OP, so that Newbies can avoid confusion.
Most of the problems are with Lithium button batteries, but they do cause significant problems for children.
- More than 80 kids nationwide have suffered permanent damage from injuries caused by ingesting button batteries.
- Fifteen children have died â 11 of them within the last six years.
- In 2010, more than 3,400 kids swallowed button batteries.
As the tiny batteries become more common, so too do swallowing emergencies.
A paediatrician is warning of the dangers of small lithium batteries after two children who swallowed them suffered "catastrophic bleeding" and died.
The medical journey for 5-year-old Emmett Rauch has consumed nearly his entire life. But Emmett is now on the soccer field â and eating and talking again after enduring 65 surgeries. In 2010, when barely 1, he swallowed a nickel-sized, lithium...
Battery ingestion usually occurs in children 5 years of age and under and the elderly. Symptoms of battery ingestion include abdominal pain, irritability, fever, vomiting, dark or bloody stools (poop), and retching. Call the National Button Battery...
And just this past December: Toddler dies after eating lithium battery two days after Christmas | PIX11
Then perhaps the advisory message should specify button batteries. O:-)
Buttons are small easy to swallow
A big dog should have no problem with a 26650

Is this getting close to the âtutorialâ area?
It does not attempt to provide a complete tutorial on Lithium-ion batteries nor the technical reasons for Li-ion dangers. It is intended as a starting point.
Perhaps if we specify which chemistry we are talking about in this thread and that there are other chemistries. When we talk about Lithium-Ion batteries what Chemistry are we talking about?
I see:
Chemistry | Nominal | Range |
Lithium Cobalt Oxide(LiCoO2) | 3.6V | 3.0-4.2V |
Lithium Manganese Oxide (LiMn2O4) | 3.6V | 3.0-4.2V |
Lithium Nickel Manganese Cobalt Oxide (LiNiMnCoO2 or NMC) | 3.6V | 3.0-4.2V |
Lithium Iron Phosphate(LiFePO4) | 3.2V | 2.5-3.65V |
Lithium Nickel Cobalt Aluminum Oxide (LiNiCoAlO2) | 3.6V | 3.0-4.2V |
Lithium Titanate (Li4Ti5O12) | 2.4V | 1.8-2.85V |
Most of the problems are with Lithium button batteries
As usual, mention the âLâ word & the conversation launches right off the rails.
Parents in this country, following the opinions of âDoctorsâ, put Lithium pills into their children, to get the brats to STFU. Maybe those reports were from people who saw a Youtube video & decided they were plenty smart enough to choose what was best for their own children & believed Lithium pills = Lithium batteries.
Yes, SawMaster, Darwin has a Theory about people like that!
Some of us have been around long enough to remember the hype and hysteria over SureFire, etc. and their dangerous expensive (thereâs a nugget of Truth in every lie) camera batteries⊠Anyone actually have experience blowing up their pockets when loose change or car keys touched a CR123? Not experience watching a Youtube video, but actual real-life experience? Hmmm?
But we werenât talking about Lithium batteries, were we?
We were talking about Lithium-ION batteries. Oh, wellâŠ
Iâm on the fence about this. I hate stupid warnings, especially warnings that are there because of the lawyers, but if they help one personâŠ
Perhaps adding comments about âbutton batteriesâ as suggested by 1dash1, and the links that describe the symptoms.
Side note:
I recently purchased peanut butter cookies. They had a âWarning: May contain nuts.â statement. The word may bothered me. If not nuts then what?
I think weâre (actually you, Mr. Scott) are on the right track with this. Rare is the question of how to handle other technologies seen, but very often newbies and LiIon come into the picture so that makes this highly important.
Rather than âdilutingâ the OP, links to threads on the other technologies would accomplish a wider view without turning this one into a âTL,DRâ scenario. Remember the audience and their limited understanding, and donât overwhelm them with TMI. We want them to read and understand the ânecessariesâ here only- the deeper parts can come later with their (hopefully) advancing interests

Précautions concernant les batteries Lithium-ion
Motivation :
La plupart des discussions/tests/modifications sur le forum BudgetLightForum (BLF) concernent des lampes de poche qui utilisent des batteries Lithium-ion rechargeables. Lâutilisation de batteries Lithium-ion implique des risques, et requiĂšre plus de prĂ©cautions que les batteries alcalines. Mais comme tout outil, lorsque quâelles sont utilisĂ©es correctement, les risques peuvent ĂȘtre rĂ©duits et maĂźtrisĂ©s.
Cible :
Ce sujet souligne les prĂ©cautions de sĂ©curitĂ© pour les utilisateurs qui sont novices dans lâutilisation de ces batteries. Il ne sâagit pas dâun tutoriel complet sur les batteries Lithium-ion, ni dâexplications techniques du danger de ces batteries. Il sâagit dâun point de dĂ©part.
Il y aura toujours des dĂ©saccords au sujet des rĂšgles de sĂ©curitĂ©. Certaines de ces rĂšgles peuvent ne pas sâapplique Ă ceux dâentre vous qui ont Ă©tĂ© assistants de laboratoire pour le âDr Goodenoughâ:https://en.wikipedia.org/wiki/John_B.\_Goodenough , mais elle sont pertinentes pour les utilisateurs les plus novices. Vous devez ĂȘtre conscients de votre niveau de connaissance et dâexpĂ©rience.
Les batteries Lithium-ion rechargeables correctement utilisĂ©es peuvent ĂȘtre sĂ»res.
Les batteries Lithium-ion utilisĂ©es de façon inadĂ©quate peuvent ĂȘtre dangereuses.
Achetez des batteries de qualité.
Economiser quelques centimes dans ce qui pourrait ĂȘtre des batteries douteuses ne vaut pas le coup.
Certaines batteries moins chĂšres pourraient ĂȘtre contrefaites ou de rĂ©cupĂ©ration.

Achetez un chargeur de qualité.
Un deuxiÚme sujet à ne pas négliger.
Une batterie de faible qualitĂ© peut ĂȘtre sĂ»re dans un chargeur de bonne qualitĂ© mais aucune batterie nâest sĂ»re dans un chargeur de piĂštre qualitĂ©. (SawMaster)
Lisez les essais/tests. Achetez un chargeur de qualitĂ© dâune marque reconnue avec de bons avis.
Les points à prendre en considération :
Protection contre la surcharge
Protection contre les inversions de polarité
Des canaux indĂ©pendants pour pouvoir charger et dĂ©charger des batteries de diffĂ©rents type en mĂȘme temps.
Une interface utilisateur qui vous indique ce que vous voulez savoir. LED dâindication ou Ă©cran LCD.
Le chargeur doit charger Ă 4,20V /- 0,05V, mais The charger should charge at 4.2V/- 0.05V, but the battery may come off at a different voltage.
My charger do not charge LiIon to 4.2V, is it faulty? [image] I see this question fairly often and most of the time the answer is: No, it works exactly as it is supposed to do. Lets start with a typical battery datasheet: [image] It says the charging voltage must be 4.20 volt, it do not say anything about the battery voltage. It do also say what the standard charge current is (This is the charge current to use if you want the specified number of cycles, higher current wâŠ

Charge/décharge
Les batteries peuvent ĂȘtre chargĂ©es entre 0*C et 45*C (32*F - 113*F)
Les batteries peuvent ĂȘtre dĂ©chargĂ©es entre â20*C et 60*C (4*F 140*F)
http://batteryuniversity.com/learn/article/charging_at_high_and_low_tempâŠ(link is external).
Ne surchargez pas vos batteries.
La tension maximum doit ĂȘtre 4.2V.
Ne charger que jusquâĂ 4.1V allongera la durĂ©e de vie de la batterie.
Un bon chargeur de batteries aide Ă Ă©viter la surcharge.
Les chargeurs de batteries peuvent charger Ă +/- 0.05V et ĂȘtre dans les tolĂ©rances quand mĂȘme.
My charger do not charge LiIon to 4.2V, is it faulty?
AprÚs la recharge, verifiéz la tension de vos batteries avec votre multimÚtre aprÚs 5min de repos.
BU-409: Charging Lithium-ion - Battery University(link is external)
Ne dĂ©chargez pas vos batteries Ă lâexcĂšs
La majoritĂ© des gens choisissent de recharger leurs batteries lorsquâelles atteignent 3,5V Ă 3,6V
Une batterie est vide lorsquâelle atteint 3,0V il faut alors la recharger.
Une batterie commence à se dégrader si elle atteint 2,5V.
Une batterie qui a atteint 2,0V doit ĂȘtre recyclĂ© (ne pas lâutiliser).
Ne chargez pas vos batteries si la température estr en dessous de zéro degrés Celcius. (0*C / 32*F)
Ne laissez pas vos batteries devenir trop chaudes.
Si vous voulez stocker des batteries dans votre voiture lâĂ©tĂ©, choisissez des piles non-rechargeables au Lithium Ă la place des batteries.
Les hautes tempĂ©ratures dĂ©gradent les batteries plus vite, mais en dessous de 60°C il nây a probablement pas de risque.
Overblown Concerns Over Li-ion Batteries Stored in Cars
http://batteryuniversity.com/learn/article/charging_at_high_and_low_tempâŠ(link is external).
Pour le stockage longue durée (plusieurs mois), il est préférable de stocker les batteries à 40-50% de charge (3,77 à 3,87V)
http://batteryuniversity.com/learn/article/how_to_store_batteries(link is external)
Lorsquâelles ne sont pas dans une lampe de poche, les batteries devraient ĂȘtre stockĂ©es dans des boites de protection/transport.
Cela les protĂšge contre les courts-circuits et les chocs.
Ne transportez jamais de batteries librement dans votre sac ou vos poches.
https://www.youtube.com/watch?v=k1LjSuq0rk8(link is external) <==
Nâutilisez pas une batterie physiquement endommagĂ©e.
Les batteries protégées sont en général plus sûre que les batteries nues.
Les batteries protĂ©gĂ©es sont Ă©quipĂ©es dâun circuit qui les protĂšge contre la surcharge et la dĂ©charge excessive.
Le circuit de protection accroßt la longueur de la batterie, et son diamÚtre. Les batteries protégées ne logent pas dans toutes les lampes de poche. Vérifiez vos lampes, sachez lesquelles sont compatibles.
Certaines lampes de poche ont une protection contre les tensions basses (pour protéger vos batteries). Connaissez vos lampes de poches !
Certaines lampes à fort courant peuvent déclancher le circuit de protection de votre batterie, et nécessitent donc une batterie non protégée. Connaissez vos lampes de =poches !
Les lampes de poches Ă plusieurs batteries comportent plus de risques que les lampes Ă une seule batterie.
Si vous débutez juste, il est judicieux de commencer par des modÚles à une seule batterie.
Lorsque vous utilisez des lampes à plusieurs batteries, et afin de réduite les risques de décharge inégale entre les batteries, il est important que vos batteries :
soient du mĂȘme type,
soient de mĂȘme marque et modĂšle,
aient la mĂȘme capacitĂ© (mAh),
soient chargĂ©es Ă la mĂȘme tension,
LâidĂ©al est de marquer vos batteries pour ĂȘtre sĂ»r dâutiliser toujours les mĂȘmes ensemble.
Chargez vos batteries dans un endroit qui ne comporte pas de matiĂšre inflammable.
Placez le charger sur un meuble, pas dans votre canapé !
Ne laissez jamais des batteries en charge sans surveillance.
VĂ©rifiez les rĂ©guliĂšrement pour ĂȘtre sĂ»r quâelles ne chauffent pas trop. TiĂšde, câest normal, brĂ»lant non !
Nota : il y a différents opinions sur la fréquence de ces vérifications.

Une batterie endommagée peut provoquer un incendie !
âDes conditions extrĂšmes tels que la surcharge , une dĂ©charge et les courts-circuits internes peuvent conduire Ă des tempĂ©ratures de batterie bien au-delĂ des caractĂ©ristiques du fabricant . Ă une tempĂ©rature critique, une chaĂźne de rĂ©actions exothermiques peut ĂȘtre dĂ©clenchĂ©e. Ces rĂ©actions conduisent Ă une augmentation supplĂ©mentaire de la tempĂ©rature, ce qui accĂ©lĂšre la cinĂ©tique de la rĂ©action. Cette dĂ©gradation de lâauto- accĂ©lĂ©ration catastrophique de la batterie Li -ion est appelĂ© emballement thermique

Au cours de lâemballement thermique , des tempĂ©ratures jusquâĂ 900 ° C peuvent ĂȘtre atteintes, et la batterie peut libĂ©rer une quantitĂ© importante de combustible et ( en cas dâinhalation dans des concentrations Ă©levĂ©es ) des gaz toxiques.
