I'm so fucking tired of people posting about rechargeable batteries who don't know anything about battery voltage works.
"Anything that actually uses power like cameras and other electronics require the full 1.5 volts that only alkaline and lithium batteries can provide."
Just an example of the type of shit I see any time someone asks about NiMh batteries online. People see 1.2v as the nominal voltage for rechargeable AAs, and then just turn off their brain. Never mind that NiMh batteries were generally out-performed alkalines for point-and-shoot digital cameras, back in the pre-smartphone days.
I'm just going to skip typing up how batteries work. A lot of you probably already know, and I don't know that anyone who doesn't know wants to learn right now. I'd be glad to explain, but I just want to lament how fast people are to dismiss any technology they don't understand.
Not just voltage, either. In the same Reddit topic someone complained that NiMh batteries weren't good for long-term use, and having to recharge them every month. Sounds like someone who either doesn't know about low self-discharge NiMh, or hasn't used rechargeable batteries in the last decade. Granted, you're still better off with alkalines if you need your battery to sit and stay charged for a decade, but there are very low self-discharge NiMh batteries available now that can keep 70% of their charge after 5 years of sitting idle.
Why would someone offer their opinion on a technology they haven't paid attention to for over a decade?
