Why aren't USB rechargeable batteries nearly as popular as the ones that require a bulky, dedicated base to charge?

Because they are more expensive and have less capacity than regular rechargeable batteries

You're wasting capacity and increasing costs

take a billion years to charge and don't have the same capacity as good ones

this. also when last I looked a lot of them weren't low self-discharge, which you really want for NiMH AAs.

I suspect bad high drain performance due to power converter circuit size constraints.
Even flashlights have a bigger drivers, although they still suck.

>Sorbo
>Literally "Sip" in Spanish
Yup. Now, that's a battery.

A true boomer would be reminiscing about NiCd batteries and how their current capacity was even better than NiMH, even if the capacity was lower.

Also this format with usb connector and the charge citcuit in battery is just a waste of space, because you need to take the battery out to charge it anyway. Sure you can charge from USB instead of dedicated device, but you end up buying a crappy charger built into every battery.
Even if actual battery needs to convert 3.5-4.2V to 1.5V, just the buck converter wouldn't take too much space.

The thing is, what application requires AAs with high current capabilities? Even proper alkalines of that size have a relatively high internal resistance, so nobody designs high-current products with AA battery holders.

Flashlights and toys

There is a reason why big boy flashlights use D batteries

>low self-discharge, which you really want for NiMH AAs.

Depends on the application.
It's always a trade-off between higher capacity or less self discharge.

because rechargeable batteries in general are fucking awful and it's cheaper to just use disposable ones unless you go through an insane amount of batteries

>$10 once
>$5 every month
Hmm... really makes you think.

>not just using lithium devices and replacing the batteries when needed

More like
>$10 once
>Batteries go dead two months into having them and don't hold charges
>Buy another
>Same problem
>Spend twenty for a pack of regular batteries
>Lasts a couple months
Lol

>$10 once
somebody hasn't bought rechargeable batteries. Those things will crap out on you within a year

This, really.

Anything that uses a lot of battery power should have a lithium battery build in not requiring constant feeding of AA batteries.

I've used the same rechargeable batteries since 2015. Maybe stop sticking up your ass.

>$30 for 8-pack of Eneloops
>5000 charges each * 8 = 40000 batteries
>$30 / 40000 = .07ยข/battery

18650*

Just buy lithium 18650 and just charge them with a proper charger. That thing is just a meme.

They're pretty nice for when you need a quick charge but already have your charger filled

*14500, 18650 is too big

somewhat related question
what are good low self discharge AAs? eneloops?

Don't use shit batteries. I'm a photographer who does a lot of work with speedlights, and I rip through insane amounts of AAs, often 30-50+ in a day when I'm on location. I use Eneloops and get 3+ years of repeated charges and discharges out of a set of them, and they also hold a charge for months if they're not used.

Eneloops or Amazon Basic. They're basically the same thing.

Guys ya'll missing the point. These USB rechargeable batteries are LITHIUM BASED making them about half the density of NiMH and even more significantly less than lead of course.
AA and AAA lithium batteries are never rechargable unless you can find some extremely expensive (and outdated) specialist batteries that likely aren't even available in your country and require specialized chargers.
Anyway Lithium is pretty nice for computer mice and other ergonomic electronics.
Sadly rechargable are so out-of-fashion and rare in the market because ignorant, wasteful consumers. We can't have nice things.

It sounds like a bad idea, why would you want that? They need charging circuitry and are more complicated to make, so I assume they have to cost more. Due to the USB plug and the circuitry they also have less space for the actual battery, so I assume their capacity is lower. Looking at this product I'd guess these are more expensive and last less. That's not very appealing.

Forgot to mention and example of lithium rechargeable batteries: Kentli

>Batteries go dead two months into having them
How the fuck? I've bought random ass no-name NiMH batteries and they still work for a few years of pretty light, general-purpose use.

AAA?

Just dropped my nexus 6 and ruined the display
Haven't been in the market for a phone for ages, but looks like Nexus devices are no longer being released though I'm looking for something that I can unlock the bootloader on and with decent Lineage support
Are any companies releasing phones with unlockable bootloaders nowadays like the Nexus line were?

Female Micro, but small charge capacity.

>small charge capacity
Because the voltage is higher. Just put them in parallel and you can use them as replacement.

Not a solution when the reason for using them is limitation of the device using it (weight and single AAA receptacle). Longevity is still a concern, though recharging saves cost (and the enviroment) in the very long run.

Only available using Lithium Manganese which is hardly any lighter than NiMH(?)

>weight and single AAA receptacle
I've never seen a AAA device that took less than 2xAAA.

>buy chink shit
>complain it's chink
gee, I wonder.

So? Are you claiming that it's unthinkable? Why make such an impotent statement?
Anyway for ref: Logitech G305 mouse. Also the ergonomic wireless mouse that I use at work but I can't remember the name.

I saw a dumbphone that can run off a AAA

Anything with a motor runs like a scalded cat on NiMH. Overclock your nose hair trimmer.

There isn't really a significant capacity penalty for getting LSD cells. There was when they first came out, but not anymore.

if anything I'd prefer NiMH to any lithium-based chemistry because NiMH doesn't go bad on the shelf like lithium does. It only wears out from actually being used, not just from time like Li.

I own and still use an MP3 player that runs off a single AAA. It works fine from NiMH.

because everything you buy already comes with a rechargeable battery and the devices that still use fucking AA batteries are only replaced once every century or so.
