I think it might be the end for my Sony Bloggie - lithium battery issues
Now, this camera wasn’t originally mine. I’m 18, and as long as I’ve been around so has this bloggie. My mom owned it originally, and then passed it town to me when I was in elementary school - where I continued to use it until around the second year of middle school. It’s served me well, and I had been considering taking it with me to college to get some pictures of me and my friends and capture the old vibe of my elementary school selfies. I turned it on today, and noticed two things.
- the sides seemed to be popping open
- when I held it to my ear (when it was on) I heard a crackling noise.
I know that it’s a long shot, and all of the signs of a battery failure are there, but is there ANY chance I could get it replaced, or replace it myself, safely? Or is it just time to say goodbye?
I’ll be keeping it powered off and in a cold room until then, for safety reasons. I’m hesitant to throw it away because I’ve heard of batteries causing fires in garbage trucks and I’d hate to be the cause of something like that.

Need a stable 5V supply in a tight space: Is a 3.7V battery + boost converter the best solution?
I am currently working on a project i have little space constraints so what i actually want is a 5V stable supply but i cant find good compact size battery so had to choose a 3.7v 2000MAH battery and now i planned of using a boost converter to regulate the 3.7v to 5v what do you guys think i want the battery size to be small and i should be able to power a stable 5v which would be the best battery and component to use?

Leaked battery cleanup
Hi everyone. I have a question about clearing up battery leakage.
I was going through some bags with old stuff (papers, toys, electronics, etc) I had saved in the back of a closet maybe 8 years ago. Had been rummaging for a while, taking things out I wanted to keep and putting them on the carpet to sort out later, rest to be thrown out in a garbage bag.
Halfway through I came across 6 old AA batteries completely covered in that white powdery/flaky stuff. That's when I noticed the white stuff on my hands and all over the inside of the bag.
Now I can't be sure if my items had any of that powder on them (I wasn't really paying attention and the carpet itself was quite dusty to start with). How can I tackle this to make that area (carpet, items) safe for pets and people who walk around the house barefoot (aka me)?
(The batteries are in a ziplock bag to be disposed of probably)

Sealed Lead Acid Battery recovery
Hi, I'm planning to recover my battery using this method. I'm using a 12V 65Ah Sealed Lead Acid (SLA) battery. When I charge the battery, the current is supposed to drop below 0.5A, but it gets stuck at 1.9A. Before I start, I would like to ask if this is worth trying or not. Here is the procedure:
1.Connect the battery to a 12V 21W light bulb, which will draw approximately 1.5A
2.Discharge it until the voltage drops to 12.00V, then disconnect the load.
3.Charge the battery using a power supply set to 13.8V at 0.5A, and wait
