• Hi all and welcome to TheWoodHaven2 brought into the 21st Century, kicking and screaming! We all have Alasdair to thank for the vast bulk of the heavy lifting to get us here, no more so than me because he's taken away a huge burden of responsibility from my shoulders and brought us to this new shiny home, with all your previous content (hopefully) still intact! Please peruse and feed back. There is still plenty to do, like changing the colour scheme, adding the banner graphic, tweaking the odd setting here and there so I have added a new thread in the 'Technical Issues, Bugs and Feature Requests' forum for you to add any issues you find, any missing settings or just anything you'd like to see added/removed from the feature set that Xenforo offers. We will get to everything over the coming weeks so please be patient, but add anything at all to the thread I mention above and we promise to get to them over the next few days/weeks/months. In the meantime, please enjoy!

I'm not a photographer, but occasionally I have to take photographs...
I have a Lumix G1. It is ancient now, but it was pretty much state-of-the-art in its day. It does everything I could possibley want. I don't use it often because my phone is quick and easy and usually adequate.
However, today I decided to get it out. Of course, the battery was flat, but when I tried to remove it, it was stuck. I really struggled to get it out. I could see that the surface was slightly swollen, a bit bloated, which was why is was stuck in the housing.
Now I assume that a fat battery is Not a Good Thing, so it has gone into the recycling tub and I've ordered a replacement.
But what is happening to the battery to make it do that? I've not, as far as I can see, abused it in any way.
Any ideas about what's going on?

It happened to an old iPhone 3 of mine. As the stuff inside degrades, I think I was told it turns to gas.
 
Chemical oxidation of the electrolyte forming crystalline build up and associated gasses.

Your lucky it did not leak chemicals and corrode the battery compartment.
 
Assuming it's Lithium ion of some variety, STORE THAT BATTERY OUTSIDE in the open air, until you can dispose of it SAFELY (that doesn't mean in general waste - the bin lorry could well catch fire, many do).

It's off-gassing flammable and toxic chemicals, along with oxygen. If it ignites, it doesn't need O2 from the air. I forget what exactly the flammable bit is, but many EV fire deaths are from inhaling it, rather than the fire itself.
 
I used to fly RC helicopters (not the ubiquitous drones) that used large capacity lithium ion batteries. A puffy battery was not a good sign and meant at least one of the cells in the pack was outgassing.

The only solution was to completely discharge the pack before the cell ruptured and then dispose of it. I used a 12V 55W light bulb, such as those used as automotive brake lights, connected to the output terminals of the pack and put it outside for a few days. Once completely discharged, the pack is safe to take to the recycling center.
 
You were lucky you managed to remove it Steve.
I tried to remove a battery from my son’s expensive magnalite (sp?) torch but it defeated me. Hate chucking nice stuff away 😡
 
Batteries puzzle me. I had a Duracell AA leak into a clock mechanism. The clock eventually stopped of course, but I took the battery out that day and found the corrosion. I thought Duracell were supposed not to leak.

In my experience, Duracell are terrible these days.

We used to use their "industrial" range batteries at work (I think the difference is mainly labelling, so it's more obvious if they get nicked!). They used to be really good & really reliable, but they moved production to China at some point (10+ years ago) and the quality went down the drain. We ditched them in the end as we had so many issues.

Energiser currently seem better, but whether that lasts or not is anyone's guess.

I replacd a Duracell in my mouse earlier, it had been there only two or three months. I didn't find the industrial ones any different to the normal ones.

I had to get some batterys out of a mini maglight I had to put a screw into the battery to pull it out.
