Feels dirty buying these, like betraying an old friend dirty
Lithium-Ion AA and AAA with insane mah on Aliexpress. Of course you need to buy a suitable charger. Some have USB-C connectors some go into a normal charger. I think the price of some of these sound good, but Li-Ion = risk. But saw a 9V with 28,000 mAh- that would keep the smoke detectors going for a while! Haven’t seen any LiFePO4 in AA OR AAA but NiMH is 1.2V the Li-Ion sustain 1.5V and have everything from 750 to 2800 mAh on the AAA, even more on the AA.
I’d be interested in what people think of these. Some are made by Eneloop, Sony, Panasonic. So brand name. But whether you can trust them. The big Choice stores would be the place to buy I guess.
I bought a load of random cheapo Chinese Li-ion cells as well as Panasonic/Sanyo/Nitecores in 18650.
Most the Chinese cells died within a couple years. Infrequently used, kept at proper storage charge levels. The properly branded cells were fine 5 years later.

/me looks at my 3.6V 20,000mAh power bank… Then look at the tiny 9V battery…..
I can't be sure how old they are in my mix, but I find LADDA breaks way more often than Eneloop. LADDAs will randomly just refuse to charge, charger flashes error message. Maybe I just used the laddas more though. I wish I labelled them all…
When this happens, just chuck the battery into a dumb charger for a couple of hours - once you've got some charge into it, usually your smarter charger will stop complaining.
Not knocking, but this sounds like the Milwaukee battery jump-start fix, which is not a good thing to do.
Rechargeable battery, HR06 AA 1.2V , 2450mAh
Only good for devices that don't specifically need 1.5v, but many do to measure things correctly or run a device as it is designed.
For that reason I would generally only use batteries like these in non critical devices, remotes, really basic stuff. Definitely don't put them in blood pressure monitors, sp02 meters, measuring scales or anything like that.
Someone who isn't me, told me, "IKEA is an extreme tax evasivey company, so I just don't buy anything from them".

AA alkalines do not deliver a constant 1.5V. They do that initially, then drop below it very quickly.

Yeah, they're definitely not a good corporate citizen. Very dodgy.
"Devices that should generally avoid using 1.2V AA rechargeable batteries (NiMH) in favour of 1.5V AA rechargeable batteries typically have specific performance or voltage requirements. Here’s a look at such devices:
High-Drain Devices: Devices that require a higher voltage to function effectively or to maintain high performance, such as:
High-Precision Equipment: Instruments that rely on precise voltage levels for accurate operation, such as:
Motorized Toys and Gadgets: Toys with small motors or servos, which may require higher voltage for optimal performance, such as:
High-Voltage Devices: Devices specifically designed for 1.5V AA batteries, where the voltage is crucial for operation, such as:
Devices with Battery Monitoring: Devices equipped with battery level indicators calibrated for 1.5V may not correctly display battery levels with 1.2V batteries, leading to inaccurate readings or performance issues.
Devices that need higher voltage for optimal performance or accuracy, or those designed with specific voltage requirements, generally benefit from 1.5V AA rechargeable batteries. Using 1.2V rechargeable batteries in these cases might result in reduced performance or functionality issues."
Did you just pull that out of ChatGPT?
Just looking at the first couple of entries
Digital Cameras: These often demand higher voltage for faster operations and longer usage times.
High-Powered Flashlights: Devices with high lumen output or advanced features might perform better with the higher voltage.
Just no. What's the last camera you had that used alkalines?
Digital cameras run on rechargeable lithium packs. Partly for their energy capacity, partly for their ability with high discharge rates. Or pro photos or serious amateurs will use something like Enerloop Pros for high cycle flash usage because using alkalines is pointlessly expensive.
Flashlights- either lithiums (usually 18650s) for the exact same reason for the serious torches, or just bog standard nickle rechargables for the small ones.
Electronic Measuring Devices: Multimeters, laser distance measurers, or high-precision tools.
Medical Equipment: Some medical devices might need a stable 1.5V to ensure accurate readings.
Multimeters take 9V cells, which are just hard to find as rechargable. Laser distance tools? Don't make me laugh- anything can power a simple handlheld laser.
So what do you think a medical device does when the alkaline battery runs low yet the device keeps working? You do know those batteries need to run down to about 1.0V before they are considered flat, right?
Not even going to bother with the rest of that post as you clearly just ripped it off somewhere without understanding anything about batteries or electronics.
@rumblytangara: I've personally experienced them affecting the measurements on medical devices and measuring scales. YEMV but if critical devices state that they are meant to be used with 1.5v batteries, it would be prudent to use the correct voltage.
Recently, Coles was selling 1.5v AAA and AA rechargeable batteries, which also had charging ports as usb type-C incorporated into the bodies of the batteries.
@Oofy Doofy: Then, again, those devices will start having the same problems as soon as the AAs are half charged. Sounds like a problem with the design of the device.
Alkaline and NiMH both exhibit massive drops.
The best chemistry for a constant voltage across capacity drops is actually lithiums. They drop from 4.2 and stay stable at around 3.6-3.7 for the majority of their capacity cycle.
Only good for devices that don't specifically need 1.5v,
This is just about every device…
but many do
Many ?
No.
The number of devices that require Alkaline batteries but won't work properly on Rechargeables is absolutely miniscule.
It's a complete none issue - if you do have a device like this, then you already know about it's limitations.
For everyone else, Rechargeables will work just fine in whatever you put them in.
2450mAh seem to be outta stock at most IKEA stores
Anyone know how reliable the noted is?
Back in Springvale in 2 weeks
I miss the fancy white one. On a positive note the aaa batteries often have more capacity than listed on the battery.
Thanks Gina! Miiiiiine… lol
