WARNING: RTC Board Battery Charging Issue

1) You say it can catch fire so the onus is on you to prove it.
You are trying to play the old reverse onus fallacy.
2) You should watch some of Dave's videos to realize he doesn't tolerate dramatic bullshit, and neither do I.
3) If you can't control your limbic system then this is the wrong forum for you.  Try the Adruino forums where they coddle the emotional fools.

1) Have you even asked what chemistry this is and looked into it ? NO!

2) Oh how fearful everyone should be of a mere member, you speak for Dave now ? You represent him do you ?

3) If you don't mind Dave and I decided who stay's, who goes and what can't be talked about. Fancy seeing how fast you can go ? You have probably not spent much time on the arduino forums where electronic theory and many of the practicalities of it go over many peoples heads as they think "once a programmer that can flash an LED an electronics engineer too".

Now someone on an emotional power trip.  Is there too much estrogen around here?
Go ahead and ban me; no loss to me and it will prove you are acting emotionally.

Here is some drama from the Arduino forum on that particular topic.

I wish I saw this thread earlier! I've been running this module with the included CR2032 battery at 5V ever since I got it with no issue until today. Today I heard a loud pop noise and looked up to see that the battery exploded and shot across the room. Pretty surprising considering how long it's been operating just fine.

Looks like I'll be getting an LIR2032 or cutting that trace!

I said until the warning of catching fire is proven it is emotional drama that doesn't belong in these forums.

Having regard for maximum ratings is not drama.

Another straw man... I agreed 4.37V is too high.
Its the warning about catching fire at that voltage that is drama.

For anyone who doesn't believe its excess drama, please post a link to a picture or video of a LIR2032 failure that involved an explosion, fire or significant smoke release, that wasn't provoked by a blowtorch, or car battery charger or similar.

why would that be drama ? you are charging the battery beyond it's operating limits. Unless you are a battery chemist you have no way of knowing what is happening electrochemically in that cell. for all you know a dendrite may grow , short the electrodes , conduct a large current , glow and set the thing on fire. Then again , nothing may happen at all. You don't now, i don't know , op doesn't know. So you stay within safe boundaries. 4.2 volt and not a microvolt more.

Op gave a warning about these circuits floating aroudn that do not have a proper cut-off voltage. fair warning.

OK, so at least one other person doesn't need their estrogen levels checked... A bit of sanity prevails.

I wouldn't be at all surprised if the LIR2032 cell bulged and vented in a controlled fashion by the seal meting and displacing.   Annoying, board damaging due to contamination, but not Youtube worthy.  However a CR2032's chemistry has no allowance whatsoever for charging so explosive venting of uncontrolled gassing is a real possibility.

Your wish has been granted, if you think blackmailing me into not banning you will work think again. You stired half of the drama up in this thread instead of having a resonable response that could even go as far as not responding to it at all. Happy cooling off for 30 days.
