Don't charge your batteries overnight!

[emus]

My view is to charge in metal box of sufficient strength to contain venting batt. I don't want to ninja catch batt rocket or fight house fire during day either.

Gold standard could be modded ammo box like RC peeps use.

Having served in the army, I'm aware of how heavy duty an ammo box is. It really takes something that strong to contain a catastrophic battery failure? Are those boxes what folks refer to as Lipo boxes?

any links to said modded ammo boxes?

I get too nervous thinking about charging my batteries overnight.. I always pop them off when going to sleep, even if not fully charged. Using an i4.

Lipo safe charging box - 1/8th scale Buggy & Truggy forum @ URC Forums

Thank you. Been looking for a good way to store batts too. One of those old ammo boxes with some of the plastic battery holders should do well I think.

It is up to your charger's circuit board to detect this and to lower/stop the charging current. If your charger fails to do so for any reason, or just simply does not have this capability (cheap charger), then it'll keep charging the 18650 until a catastrophic failure occurs.

Worse, are the ones who plug it into their computer and go to bed for the night.

There was a house fire in Spokane, Wa caused by a guy who made a practice of charging his that way.
It overcharged (naturally), blew out the end and lit up some cushions nearby.
Not much damage, and no one hurt, but can you spell "STUPID"

You are the prime example of why I made this thread. It takes a lot of willpower for me not to criticize your intelligence, but I know it is not your fault for how ignorant you are. There is a reason why the shipment of lithium batteries on airplanes is heavily regulated while the shipment of bubblegum is not. There is clearly a known risk with the use of lithium batteries and thus precautions are highly useful when dealing with them. Your reasoning for your conclusions is so horrid that nothing in your post resembles the truth. You should step back and look at what you can regard as useful evidence. The fact that it has not happened to you and you know very little about it, is no evidence at all for any bit of the truth. Also, extrapolating from what you've said I am sure that you do not know how inductive logic works to have anything useful to say about probabilities, and which instance is more probable than another.

Very eloquent words but they are just words. Show me some proof. Give me links (proof) of lets say 10 instances of occurrence in the last month, or is this something that everyone know happens every day but no one reports it.

Thanks for refraining yourself from criticizing my intelligence.

Would it be safe to put the charger in a metal box, like a cash box or a tool box, maybe with some holes drilled in it? Would that contain a catastrophic failure?

Any metal box as long as it's not aluminum or magnesium will be plenty sufficient to contain a thermal event from a vaping sized battery. Just like the hobby grade charges talked about earlier, there are solutions used in radio control that would be overkill for this purpose. I have LiPo batteries (which are much less stable than the LiMn used in vaping) that are 44.4 volts and 10,000 mAh where most 18650's are 3.7 volt and around 2,000 mAh. You could go the ammo-can route which would be the gold-standard for containment but certainly not needed.

Many boxes of many varieties are referred to as LiPo boxes. The simple solution would be a LiPo charging bag. When I refer to my LiPo safe, it's exactly that, a safe. I bought a cheap gun safe and modified it for charging/storing my LiPo's simply because at any given time I will have several dozen, some for personal use and others to re-sell in my house. Maybe not the safest solution to have them all stored in the same container but safer than having them sitting all around the workshop.

 

[Vaparious]

This thread is a goldmine of info. Thanks! Safety first...

 

[leong jenny]

YES, and please note never charge the battery off the computer.

 

[Rickajho]

I charge them while I'm home and awake. I also use an Intellicharger I4 which is a very safe charger but it could fail so I don't trust it 100%.

Xtar and Plia are safe chargers. This is what people have to report about Nitecore chargers here, and why I would never have one anywhere in/near/around my house. Why people love these things is beyond me. Oh yeah, they're cheap.

FWIW I've forgotten about batteries in my Efest LUC V4 for days and don't give it a single thought. Having an intelligent charger that stops charging once it's reached 4.2v is a must IMO.

I used to have a Trustfire charger that would overcharge and I would definitely always worry about batteries staying in it overnight.

 

[trentenmarschel]

also thought this chart might be helpful.

 

[Bochawa]

Good stuff. With my first mod in the mail this is very timely!

 

[Rob0506]

I fail to see how charging an 18650 on an intelligent charger (even if it isn't all that intelligent) is different from charging a cell phone overnight. How much money and space do you think they dedicate to battery safety in a typical phone? If I am charging my Lipo batteries I do observe the safety rules you mentioned and charge in a lipo safe bag, but for a normal 18650 I don't really sweat it. There just doesn't seem to be evidence to support the paranoia out there about battery charging.

 

[Completely Average]

ROFLMAO at this thread.



Raise you hand if you have 12+ hours a day, every other day to babysit a 2900 mAh battery recharging.

As for the "Oh noze, your charger might fail to stop charging" belief, it could do that while you're sitting right next to it and how are you going to know? Do you sit there with a multimeter measuring the charge every second as it goes? Or would you be sitting there completely oblivious until it exploded?

I work with batteries that are FAR more dangerous than these little dinky things. Come to my work and I'll show you an APC with 3 TONS of highly explosive unprotected batteries inside. Funny how I can rely on the intelligent charger in that to prevent catastrophic failure but I'm supposed to be scared of the intelligent charger that charges a pair of what are essentially flashlight batteries.


BTW, how many of you worry about your unprotected 60lb car battery exploding?

It happens.

Good going, this is the only thread you've posted in and you're already insulting people.
