Can you help with our research into button batteries?


#1

Button batteries or coin batteries can prove very dangerous to small children especially when swallowed. However, it’s not just children’s products that contain button batteries they are used for many common household products.

Can you please check your home if you have any products using button batteries. Button batteries can be in a range of products including bathroom and kitchen scales, thermometers (body temperature and for meat), watches, remote controls, night and reading lights, torches, bicycle and dog lead lights, flameless candles, toys and games, calculators, musical greeting cards

Please let us know in the comments below or send an email to money@choice.com.au:

  • What is the product (type & brand) eg Roche Glucosemeter
  • How easy you can open the battery compartment - do you need a tool like a coin or screw driver to open it or can you just open it with your finger or fingernail?
  • Type of button battery used if you know eg CR2032
  • Where you bought it, if you still remember

  • Batteries were removed immediately after purchase as we didn’t want risk of the cover door breaking and batteries being released (also if our child didn’t know about the noise it made, there would be no need to continually replace batteries). Difficult to remove but plastic seems brittle and cover may break if damaged/hit.

These are all lithium 2025 or 2032 or hearing aid style…

Remote for my (jailbroken and kodi’d) appletv. Easy to access, but then the remote is so small a kid could almost choke on the remote

Computer motherboards. A non-issue really - hard to access.

Remote for car stereo - easy to access, but I still don’t know why I have a remote in the car … it came with the stereo.

Car key fobs - I had to google how to open the cranky things - kids could choke on the key itself?

Travel alarm clock - hard to get to…

Thankfully he electronic trigger on the air pistol I’m looking at takes AA’s - who knows how dangerous that would be if it took miniature batteries? :wink:

The small button batteries are ubiquitous. I have just listed what comes to mind.

Bathroom Scales

  • Slide off cover
  • not sure several years ago

Torch/Laser Pointer

  • Unscrew the end to get to 3x batteries.
  • bought out of China

Watches

  • Unscrew back plate - not easy to access
  • bought in a variety of stores and on-line

Garage door remote fobs x4

  • Batteries under a slip off cover. Fairly easy to access
  • Received with house and bought on-line

Clip on LED reading light

  • Batteries under a slip off cover. Fairly easy to access
  • can’t remember

I’m sure that this is just the tip of the iceberg, as the only time I consciously take notice of what the battery type is is when something stops working.


#16

Sometime, a small magnet will enable an easy removal of a battery.


#17

I think others have pretty much covered the devices in which I have these batteries.

More often it will cause more severe injuries.


#18

In the scheme of things, it is small, but Snark clip on guitar tuner requires a button battery. It slides out easy with no locking mechanism, pop out old battery and pop in new one and push shut.

I’ve gone through a few Snarks because they battery slot has worked loose.

Never gave it that much though until I started taking my guitar to playgroups and little fingers like to touch… as I usually just leave it on my guitar head.
