Comment on I'm so sick of dinky shitty devices with garbage rechargeable batteries
scrubbles@poptalk.scrubbles.tech 10 months agoWhat are you talking about? I literally just bought a charger today for AA and AAA batteries for $15 today so I’d have 2 chargers at home. I’m still using my original AA rechargeable batteries after 6 years now. Are you saying that’s somehow worse than single use batteries? My rechargeables last just as long as alkaline ones and I haven’t had to buy batteries in years.
Check your misinformation.

Man chill, he’s right, single use batteries have a higher energy desires than rechargable ones. And somewhere everybody is misreading that OP was talking about built-in chargers.
Not an argument not to use rechargable ones though

That poster is still a dingus, because lithium battery chemistries require even more complicated charging circuitry than NiMH or NiCd. Lithium ion powered devices also have “complicated chargers” built into them, so it’s a non-argument anyway.
What’s true is that lithium ion has higher energy density than NiCd or NiMH. What’s not true is the notion that consumer primary cells (alkaline or zinc-carbon) have more capacity than NiMH, because they don’t. A brand name alkaline AA cell has around 2200-2400 mAh available, but a really good quality (i.e. not Amazon Basics or whatever other cheap horeshit) NiMH AA can have up to 3000. NiMH chemistry also handles high current loads significantly better than alkaline, which is important for high drain devices (cameras, flashlights, motorized toys) but less important for low drain devices expected to have a long shelf life (remotes).

I was sure that alkaline has a higher energy density than NiMH but you are right, they don’t. …wikipedia.org/…/Comparison_of_commercial_battery… Thanks for the correction.
