That made me literally laugh out loud! :D Reminded me of the people on Extreme Cheapskates who wash their used paper towels with soap and water and then hang them up to dry. |

The 'problem' I have at times with 'AA' 'Rechargeables' is in the likes of some Cameras etc. Rechargeables are typically 1.2v instead of 1.5v. So "Low Battery" comes on too early!!! :-\ P.S... Re: say 'AA' batteries in general... you can tell when they are 'CRAP' due to their WEIGHT!!! When a pack of 4 'Duracells' weighs as much as a 12-pack of cheapo garbage!! ;D P.P.S... Any company, including 'Eveready' etc, can EASILY make normal 'disposable' batteries last 10 times longer!, but deliberately DONT due to simple economics for the company!!! :box: |

Other common uses also have the same profile, low power long life: clocks, thermostats, doorbells, sensors, wireless mice / keyboards etc. --- End quote --- That sounds more like you are extrapolating from what you have at home, not any serious numbers. --- Quote from: M0HZH on June 30, 2020, 09:22:00 pm ---The recent game controllers from Sony/Microsoft/Nintendo are rechargeable now, --- End quote --- Um, nope: New Xbox controllers: https://www.vg247.com/2020/03/31/why-xbox-series-x-controller-aa-batteries/ The Oculus controllers I have mentioned already. Nintendo Wii/Wii-U controllers were never rechargeable, Switch's Joycons can use AAs as well in the form of an external battery pack: https://en-americas-support.nintendo.com/app/answers/detail/a_id/22775/~/joy-con-aa-battery-pack-faq Valve's Steam controller uses AAs too. Only the Sony gamepads use internal rechargeable batteries, as do PS Move controllers (used by the Playstation VR system). Also some XBox controllers were available in a both rechargeable and AA powered versions. --- Quote from: M0HZH on June 30, 2020, 09:22:00 pm ---digital cameras have made the switch long time ago and all the other stuff is a small market comparatively. --- End quote --- Again, nope. Granted, most digital cameras use lithium cells these days but not all - and I am not speaking about the various disposable cameras: https://www.ephotozine.com/article/top-10-best-aa-battery-powered-cameras-2019-20942 There are also accessories like this battery grip for Canon cameras: https://www.amazon.com/Powerextra-Battery-AA-size-Infrared-batteries/dp/B01NA7J50G These are quite popular by pros because it is always better to run to a store and grab a set of AAs than to be screwed because all your batteries are flat due to some unforeseen event and something important is about to happen. |

Not sure if anyone brought up NiCd batteries yet... they also have benefits in certain applications. While many people think Lithium variants have supplanted everything, NiCd are still used in a lot of devices. They are quite resilient, usually sit on a trickle-charger 24-7 and ready for use when needed. I have NiCd's in devices over 20 years old that I still use, fairly forgiving and have their applications. Many home appliances like shavers, toothbrushes, cordless phones, drills, vacuums, etc... use these. Also one of my old Tamiya 1980's era remote control cars uses a 7.2v NiCd pack, still performing after over 30 years. Unfortunately many appliances use non-standard NiCd battery sizes or create serially-connected "packs" of batteries soldered together and wrapped in some plastic (or hidden inside the device) with some custom wire connector. One of the cells in the middle of the pack may get bad, or need individual reconditioning. If you could separate the pack, or if the device allowed you to insert individual cells you could likely find the culprit, recondition or replace the bad cell and keep using it for much longer. I think we all understand that different battery technologies exist and persist because each has different applications for which they are most optimal. There is no "ideal" rechargeable yet that fits every single situation, hence the need for both one-use and rechargeable energy sources. Banning is not an option, but educating users and controlling the waste stream is the key. I personally test out all my batteries (especially from the high-drain devices) at the end of their useful life and will typically re-purpose them into lower-drain devices (like remotes) that typically sit on standby. Usually the battery voltage in a high-drain device will tank quickly and not be able to stay above the operating voltage (of a toy car, for example). But put it into a remote or keyboard that uses very little current draw, and the voltage coming out of the "dead" battery is still good enough to last a long time. |

"different battery technologies exist and persist because each has different applications for which they are most optimal." Exactly! Is a little bit like opamps. If there was a single device which was the "best" across all applications, only that paticular number would sell. But we have 100s of different opamps, each serving an specific requirement, sometimes very niche. |
