I have a battery hot take.

Alkaline batteries are obsolete — but their predecessor isn't

@TechConnectify you could ask TechTest for help with the rechargable battery video. German youtuber (talks german in videos) who has tested countless nickel metal hydrite batteries and is now mostly focusing on lithium ion

Unfortunately I can't confirm the "alkaline batteries are all about the same, regardless of the brand" claim. Some non-brand batteries (not from a Dollar-Tree-like shop) can have a much lower capacity than one would expect (the non-brand batteries in my post lasted one month where brand batteries lasted over a year in a digital clock).

Maybe I should give CarbonZink a try.

I heard batteries needed to charge your car & of course Virgil Simms' invention sprang to mind immediately

@TechConnectify almost impossible to find heavy duty batteries in the stores around here. I did have a good stroke of luck finding them at Harbor Freight for a while. They weren’t great, but they were inexpensive. Last time I was there I didn’t see any though. They were black and yellow. Now they seem to only carry alkaline.
@TechConnectify "Alkaline batteries name is far too basic" got a laugh out of me
@TechConnectify my son dusted off our Wii last weekend and I learned that non rechargeable AA are 1.5V while the rechargeables we have are 1.2V so the wiimotes would work with them.
@TechConnectify Sigh. 30 minutes about Alkaline batteries. And yet, I know I'm going to watch it anyway.
@TechConnectify SUPER HEAVY DUTY (ironic)
@TechConnectify hot take: if your battery is hot, take it away
@TechConnectify
Can you provide a link to the battery load tester that you used?
