Not bad for a first time post, eh?
Seems like a ATL according to Camelx3.
Be mindful to get free delivery you need to buy $59 from international Amazon, or just buy 2 packs like I did.
CamelCamelCamel.
Good job first post for a classic.
This is 2000mAh and 800mAh.
Pre-empting - the LADDA AA 2450mAh 4pk + AAA 750mAh 4pk combo is $20 total ($12+8) atm.
AAA has been OOS for ages
When I went into IKEA last week they were getting quite large stock end this month. Perth. See they got the AA but no AAA. stocked up last time they had them.
Yes Ladda for me every time
Been trying to get AAA for 6 months. They're unobtanium in Melbourne at any IKEA. They don't exist
Didn't need it when I needed it…
Bought a pack for the smart locks 😅
I've actually they last about 20-30% less compared to alkaline batteries.
In many other battery powered items too, such as toys and torches.
May be due to the lower voltage? 1.2v vs. 1.5v?
they last about 20-30% less compared to alkaline batteries.
In some devices, yes. In other devices, eneloops (and other NiMh batteries) last longer than alkaline batteries, because they stay above 1.1V for their entire discharge curve, compared to alkalines that are 0.8V at the end of their discharge curve.
What kind of devices are people using AA and AAA for, nowadays?
For me, it is the tv remotes… and nothing else
The Eneloop value proposition has evaporated for me.
Other than remotes, kids toys, torches, shavers, mouse n keyboard.
I stopped using them for many of those devices because they often require and/or perform much better with alkaline 1.5v rather than the nimh 1.2v.
I have literally never noticed a use case where a 1.5V alkaline was needed or even noticeably better over a 1.2V NiMH
Alkalines discharge to 1.2V pretty quickly (about halfway through useable lifespan and moderate current draw) anyway.
NiMH starts well above 1.2V and then their curve levels off around 1.2V and stays there in a closer to linear function, far moreso than alkaline.
I'm using NiMH i flashlights, remotes (sometimes- they are a poor value proposition here), automatic lights, toys, BP monitors, mice.
@rumblytangara: It multiples up with multiple batteries. There are devices that require short bursts of 5v like automated cat flaps. 4x1.5=6 but 4x1.2=4.8. A 5v buck regulator wouldn't work with 4.8v.
@xmail: That would mean you're only getting half the life from the alkaline cells anyway as under moderate draw 50% of their lifespan is 1.2V-1V (1V is where the cell is considered exhausted).
The whole "Alkalines are 1.5V" idea is overly simplistic and doesn't translate into real world use for anything apart from very low drain applications.
So this sounds very much like a badly designed product that really should be using 5x AAs, or two Lions. I guess if the cat flap used capacitors to activate a solenoid, the current draw to power the caps would be low and then 4 cells would still eek out most the capacity, but this sounds a niche product in comparison to what most people are using AAs for.
Rechargables don't make economic sense for some applications- I'd agree with cat flaps (if they use capacitors) and remotes. But I use them for just about everything else and have never encountered problems. I still use them in remotes sometimes as they are less prone to leakage.
They all get used at Christmas in LED lit decorations around the house.
When you have young kids you know where it goes haha.
The problem is I don't know where they go! Where do all the AAAs go? Spent 20min opening different devices the other day trying to find some. Kept getting AAs. Finally stole some out of a light sabre which I expected to be AA.
Wifes back massager
Back or front ?
Yes
The last couple of things that I used them for:
Kitchen scales
Kids bubble toy
Torch
Little kitchen milk frother thing that my wife loves using for instant gravy
TV remote
2x air con remotes
I'm struggling to think of anything else though
I thought this too, until having a baby.
Torches, bike lights, Etrex gps, led clock.
For hiking and camping it’s better to take spare batteries, quicker to change over than recharging with a usb power pack
For me, lots of kids toys followed by salt and pepper grinder and soap dispenser.
A million IoT sensors, mainly door/window sensors which I also want to use for things like detecting when mail is delivered. I say want because I bought a mountain of sensors with enough AAA's to power 3, just before the Ladda's went out of stock after I'd been walking past a huge pile of them for months, figures.
Remotes: TV/chromecast/pedestal fans/PS3/VCR. 2 wireless mice. Blood pressure monitor takes 4 AAAs.
Can anyone recommend a suitable charger for the AAA variant?
Any ikea ones
The IKEA chargers vary from poor to terrible. Don't buy them, they're the cheapest rubbish chargers IKEA could get.
I spelled out why IKEA's STENKOL charger is so bad here:
https://www.ozbargain.com.au/comment/16327689/redir
IKEA's other chargers are "dumb" timer-based chargers, which will damage your batteries even faster.
I had to return an Ikea charger because it refused to charge many batteries, claiming they were bad (blinking light). It was the charger that looked like a book.
Both my chargers Lii-402 and Nitecore D4 are happy with these batteries.
That link was an excellent writeup. It's so rare that someone has a clue about how charging and batteries work and how delta temp/time is relevant to NiMH.

Current deal: https://www.ozbargain.com.au/node/896704
For a casual user do you recommend Panasonic smart or XTAR L4? Both are selling below $20 on Amazon now.
do you recommend Panasonic smart or XTAR L4?
I haven't looked at that charger before, the data sheet is here:
https://www.xtar.cc/download/l4-data-sheet/
It's not good. Says maximum 500mA charge current for AA NiMh batteries, and takes 6 hours to charge a 2500mAh battery. Both are red flags. Also says it uses a secret algorithm to charge the batteries, but looking at the charging curve, it's obviously using high-voltage cutoff, followed by trickle charging to wallpaper over the problems of using high-voltage cutoff. I wouldn't use it.
Both are selling below $20 on Amazon now
I'll bet the Panasonic charger you're looking at is the "overnight" (also known as "10 hour") charger, not the "smart and quick" one. The overnight charger, like all timer-cutoff chargers, is designed to damage batteries.
If you can find the Panasonic "smart and quick" charger (1.5 hours) for $20, post it as a deal, it'll be very popular.
There are a zillion chargers, what are your requirements?
MAHA 9000 is a good one and it covers AA and AAA. But it doesn't do lithiums and might be too much for most people.
Anyone bought eneloops from the AliExpress eneloop store? I’m assuming they’re legit?
link?
They look legit but similar price to Amazon which is quicker
Does anyone know if the fact that it's optimised to work under lower temperatures make it a bad purchase for someone in QLD?
No.
They are uneconomic purchases if you are trying to use them for devices that last for years like TV remotes though.
Thanks, it would be mostly for my Xbox controllers
Awesome for XBox controllers, I find Ive saved a bunch using Eneloops.
for devices that last for years like TV remotes though.
If you've ever had a flat alkaline battery "melt down" inside your TV remote, and looked at the price of a genuine replacement remote, the eneloop batteries are an absolute bargain.
I have rechargeable NiMh batteries in all my remote controls for this very reason. All of the batteries combined cost less than a single replacement remote control.
Though I do find that using NiMh batteries in TV and DVD remotes makes them lose capacity, so when recharging them, I have to put them through a few charge-discharge cycles to recover their capacity.
If you've ever had a flat alkaline battery "melt down" inside your TV remote, and looked at the price of a genuine replacement remote, the eneloop batteries are an absolute bargain.
Or you could just replace your alkaline cells once a year.
"It" as in Eneloops?
If so, no. I'm running Eneloops in all sorts of devices with nil issues.
Wish this was just AAAs. Have a big stockpile of AAs but no spare AAAs.

Thanks, forgot they had it. Put an order last night and picked up this morning. Needed some AAAs.
