I've accumulated quite a lot of LR43 and LR44 batteries since collecting, and I have most of the loose ones piled up in a plastic bag. About a week ago a heard a loud bang like a cap gun over by my G&W collection, and about 15 minutes later the same bang again. The next night another bang happened. I was hoping that none of my games had exploded, and that maybe it was a light bulb or something. Well, I just happened to go through my bag of batteries, and 3 of them look as if they exploded! I'm almost positive this was what made those small "explosion" noises now. Has anyone else experienced this?! I didn't think these little button batteries could explode like that under normal conditions!

I guess that piling them up in a plastic bag isn't the wisest thing to do. My bet is that they have shorted and because of that they have gotten warm and exploded.

Yes, the plastic bag might have something to do with it. It's a small ziploc and I had it sealed, so I'm wondering if these batteries do need to "breathe" as Aris suggested. The original battery packs in the game boxes do have holes in the top and bottom, so maybe without this sort of ventilation they will eventually explode if very old, corroded, or hot, etc. I can't believe no one on here has had this experience, or at least hasn't posted about it.

Err.. that's not what runepune suggested Ash. Charged batteries shouldn't be accumulated together because in some cases if they touch each other they can be shorted which leads to heat and possible explosion..

All batteries produce an exothermic (heat producing) reaction when then they form any sort of 'closed circuit'. What also needs to be considered is the fact that any metal will eventually become fatigued when it undergoes massive temperature extremes, eg : from cold to hot, hot to cold. Given that the Maxwell LR 43/44 batteries vary in age (20 years minimum & 30 years maximum) and we have no way of knowing exactly how any G&W has been stored for the majority of it's lifetime & it can be speculated that at some stage they have been sitting in a warehouse (which are generally hot & have poor ventilation) for some time, so the small rubber seal that hold the batteries together will eventually become comprimised, hence allowing such phenomena (exploding batteries) to occur. Moisture/water is also another contributing factor as it can permeate the rubber seal and then react with the elements/compounds inside a battery (generally a metal & an acid) which will create a gaseous byproduct & also attribute to destroying the rubber seal, which is why sometimes you see batteries that have swelled/bloated. If anyone has any of these swelled/bloated batteries, dispose of them immediately!!!! Hopefully this helps further explain things. Damo

Thanks for the detailed explanation Professor Damian! ;D I remember having some of those "bloated" batteries you describe. They weren't LR44s or even 43s, they were 357s, and it was the first time I ever saw 357s, and I thought, "what a stupid design! You can't even use them properly b/c it's so hard to close the battery cover with the convex top that they have!!" LOL! D'uh!!! AC

I'm just wondering if having them sealed tightly in a plastic bag may have contributed to them heating up.

Damo Damo, your explanation describes exactly what happened to my batteries! I remember those batteries were bloated before they exploded. I better check through the others and get rid of any slightly deformed ones as you suggest. Thanks for the input!

Just found this on YouTube:
Mine sounded a lot louder than this one though.

Ha! Well, I didn't have them sitting under a blazing firework. They were sitting on the shelf in my cold bedroom. I checked the comments on that YouTube clip, and it looks like someone else had the same problem as I did (had three batteries explode in a bag).
