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.

    Cordless power tools are absolutely worth it, if you use them even infrequently, and every single contactor I know uses them. The battery packs are ridiculously priced but they wouldn’t be used so ubiquitously (especially by professionals) if they weren’t worth the drawbacks. Having to string out extension cords for every tool would be a nightmare.

      I dunno, if you use them infrequently, having to string out a cord shouldn’t be any more of a hassle than for a vacuum, no?

      And if you’re buying a cheap, probably-won’t-use-this much tool, I think you can get better power out of a corded tool for the price, which seems like a god tradeoff to me.
