I know these are currently out of fashion but I’m still thankful they exist.

Let’s remind ourselves of devices that use(d) these standardized batteries:

  • Toys
  • Digital cameras
  • Torches
  • Gadgets like fans
  • Wireless keyboards
  • TV remotes

Thanks to having a standardized system of batteries,

  • You can use the same battery across several devices. This is a no brainer but it’s very practical.
  • Batteries can charge quicker thanks to being put in a dedicated charger and not being limited by USB cables. (But yes I concede that USB has been updated for faster charging over the years)
  • Devices don’t have down time when their battery is charging. To charge, the battery is removed from the device and can immediately be replaced with a fresh one.
  • You’ll never have to trash a device due to an expired battery. Just buy a replacement. And building on this…
  • Any improvements in future battery technology can be retro-fitted into your existing devices. And there is a high incentive for future improvement, because…
  • An accessible (due to easy replacement) and large (due to many devices) battery market is very attractive to competition.

If you look at the pros I listed, they all happen to be things that would be very useful for electric cars. So I think it would aid the adoption of electric cars if their batteries were standardized too.

    Those batteries in your photo are NiMH batteries… which discharge on their own at a fairly rapid rate even if you’re not using them at all. They’re also pretty big and heavy for the amount of power they provide (which, due to the self-discharge issue, is effectively a lot lower than the official number on the battery).

    I strongly recommend investing in devices that use 18650 batteries. They’re about the same size/weight as a AA, and they last much longer (both in terms of from full to flat and also the number of years (decades?) of use you’ll get from the battery.

    A lot of “proprietary” batteries are in fact a bunch of 18650 cells wired together.

    It’s worth investing in good ones - the quality varies significantly from brand to the next. With a good 18650 cell, you won’t be replacing it when the battery expires, you’ll be transferring it to a new gadget when the gadget is broken or so old that you decided to buy a new/better model.
