Our kid's musical plush uses a USB-rechargable battery instead of accumulators

I know it's proper usage of the word accumulators, but I've basically never heard anyone refer to them that way.

Are you a part of the Borg by any chance, OP? 🙂

Sorry, English is not my mothertongue. How would you reformulate the title in proper English?
- Small cylinder batteries are just called "batteries" in English. If you mean the type that you can charge, we call those "rechargeable batteries". People will infer that you mean the cylinders even though usb batteries are also rechargeable (I'd call that an "internal battery").
  
  I like the sound of accumulator more though. In English that word is usually reserved for hydraulics or electrical engineers
- Disposable batteries?
- I think this is awesome, don't change your verbiage, it was just interesting. Thank you for sharing! I got some cultural experience today.
- And what is your mothertongue?
Is it, though? Accumulators are rechargeable by definition. Disposable batteries are, well, disposable.
- I don't know that accumulators have to be rechargeable, just an object that collects (even if only at its initial charge) and stores energy.
  
  It's just not a term I hear often, and I thought it was interesting. I like also hearing about how other countries use the term, it's enlightening. I didn't realize that it is the primary term to refer to a battery in several countries.
Not to hold it against them, but they are European judging by the wall sockets.

We've had one like that, you could even plug it into a computer and access it as a usb flash drive and change the sounds

Would not recommend plugging USB into a computer with access to anything important to you.

I'm not a privacy nut, but USB should be treated like a sex toy of* unknown origin.
- That is very true.
  
  The toy we had was from around 2010, I think that there may have been less risk back then, but your point still stands (PS I was using linux as a desktop)
Wait, this exact one? Cause we have it and that could be interesting
- Not that toy, but the box looked much the same

Unless the batteries are easily user replaceable, this is just planned obsolescence to get you to buy another when the batteries die.

If it includes an easy to replace battery? Then you've bought from a good company who gives a damn about both environment and consumers.

If it's not a phone where size matters it's almost always some generic battery that you could replace with another that's not even the same size. They might have different connectors on it, but usually it's just a positive and negative lead that somehow connects.
- True, but literally the vast majority of people don't know enough about batteries to do that. Which is what makes it anti-consumer and anti-environmentally conscious.
- Many gadgets are smaller than an 18650 (the oversized thumb sized cell), which is about the only standard lithium size I've ever seen be replaceable. There's hardwired rectangles everywhere, not just phones

push eax

the placement is crazy tho

I hope it’s not lithium ion. Seems like that would be overkill for a stuffed animal.

Lithium batteries are very compact and competitive price wise. Not overkill in the slightest.
- They often get thrown in the garbage instead of being recycled. They can catch fire when punctured. Not something I would want near a small child when a NiMH would do just as well.

oooff no excuse to turn it off then?
