buy again and return with old receipt
Now that really is big brain thinking. I like it.
Return and earn.
I paid full price
Please hand in your Ozbargain membership.
Fair.
Thanks all. It's been a blast.
I just bought over $100 worth earlier in the week. Super bummed.
If you don't mind me asking, what's your use for 30+ AAAs?
My kid had a birthday and got a bunch of remote control junk which needed a ton of batteries. This was the critical moment which made me move from alkaline to rechargeable.
OMGGGGG HOLY WHAT THE EFFFFFFFFFFFF $3 OFF
ikr well it's better than the crappy $2 off last time which everyone was salivating over. If you're patient and buy sale items in bulk the savings add up.
buy sale items in bulk
No, and I'm surprised you're not new here. People can subscribe to product alerts and wait out bulk purchases until sales, ie. switching your household to rechargeables.
Such is the art of stacking - buy an Ikea gift card on sale in advance like I did, wait for a product sale and add a discount code on checkout. If you can wait, why not save money. I think your point is a consumerist attitude whereas I'm not here to shop heaps of "bargains" (quotation marks to emphasise that utilising every deal isn't real bargain hunting, that would be spending more just to hoard which is counter intuitive and seems to be common here).
You say this like it's about the dollar.
Ozbargain ain't for you bud.
I would buy literally thousands of items a year.
By making sure to save at least $1 on each item I buy by waiting for sales and such, I'll easily have a few extra thousand at the end of each year.
$1 per item, if you "live by the bargains" isn't a small amount anymore.
It's about not paying full price, a discount is still a discount unless it's jackedup.
A dollar saved .. is a dollar earnt
Lol
$4 for the AAAs
Can you make this comment on every deal that is 20% off?
Well put.
Brace yourself for the $2 cash-backs from Cashrewards.
This might to some seem like a basic question to some, but what are the best applications for rechargeable batteries? I don't know if they are better for lower discharge applications (TV remotes, LED string lights, alarm clock) or higher discharge applications (head torch)?
I don't have kids so don't have many toys needing replaceable batteries. My toys have their own in-built batteries (yeah yeah…..cue profile name and naughty toy association sniggers).
Also I assume the AA numbers for the Laddas are capacity? Are they same size?
Same physical size, yeah.
Generally rechargables are better in medium to high discharge scenarios and ones where the exact voltage isn't important since they tend to have slightly lower voltages (1.2V for NiMH vs 1.5V for Alkaline/Heavy Duty batteries). Modern batteries with low self-discharge (LSD) can be good for low drain applications though.
Alkaline batteries will sag to around 1.2v under any real load anyway, so there's not much difference.
You also have to take into account the internal resistance - the battery is not only a drive but a component of the system.
Same phyiscal size, yeah.
The positive terminal does appear to be shorter than some other batteries - I have a device or two that the positive terminal struggles to make contact with. I would however put this down to the device not meeting spec rather than the battery, but it is a problem I've only had with the LADDA's - the alkalines I use (Varta) have always reached. This is also only comparing those two brands - you could potentially have the same issue with every other battery brand.
My toys have their own in-built batteries (yeah yeah…..cue profile name and naughty toy association sniggers).
lets hope li-ion batteries won’t catch on fire while you’re using your naughty toy…
I use them everywhere, even TV remote ….. they don't last as long as alkaline when not used, shelf life, but if flat I recharge and am ready to go again instead of going to supermarket or bunnings for alkalines …
This. Yes, they won't sit holding charge in idle devices for as long as alkalines, but when they're flat it's a matter of charging them, not tossing the dead ones and replacing.
Go for the 2450 capacity for high drain applications, they provide longer runtimes in torches and are designed for fast discharges. The 1900 and 750s can take more charge cycles.
30 pack AAA Energizer is $30. This is $2 each. So double the price. Assuming NiMH has 33% less capacity, then 3 recharges ought to equalize costs. I pretty much use rechargeables exclusively. Most of my applications are RF toy remotes and home automations, and also use them with C/D adapters for larger toys. I have around 100 of each of AA and AAA types.
3 recharges ought to equalize costs.
You can also recharge alkalines up to 15 times though. You need to recharge your NiMH's at least 31 times to equalize costs.
Fascinating, I never heard it was possible to recharge alkalines. I believed the fear mongering around they would heat up and possibly explode if you tried!
Makes me a bit annoyed at the hundreds i've thrown out over the years after a single use.
Mind you, I wouldn't go back now anyway after investing in NiMH, just because i've had expensive torches and devices destroyed from leaking alkalines.
@ssfps: The heating up may be a problem - the thinning of the case which is physically diminished by the reactions which release the stored energy will be.
Please don't take this as an absolute - the short answer is: it depends.
Do your research.
There is a reason why this isn't common practice.
You may well end up with a big mess in your battery compartment or some damaged equipment at worst.I have an old Rezap. The catch is you can't really recharge heavily discharged alkalines, works better when topping up lightly used ones. There's also a good chance they'll end up leaking.
Recharging alkaline batteries significantly increases the chance that they will leak.
Not a risk I want to take. I'd say my eneloops get recharged way more than 20 times, so I'm well ahead in savings and haven't lost expensive equipment due to leaking batteries.
Alkaline batteries specifically designed to be rechargeable existed, and died long ago. They just weren't good enough compared to the competition from NiCad and NiMh batteries. And that was before low-self-discharge high-capacity NiMh batteries (e.g. eneloops) were available! The rechargeable alkaline batteries had to specially designed not to leak or burst, which is what frequently happened when people tried recharging "ordinary" alkaline batteries.
They were well-known to have a poor number of charge cycles and the capacity reduces dramatically with every charge. Read:
https://batteryuniversity.com/article/will-the-reusable-alka…
and
https://www.ozbargain.com.au/node/18703A few Wikipedia quotes sum them up. Talking about the alkalines that were specially designed to be recharged:
Cells have a limited cycle life, which is affected by deep discharge; the first cycle gives the greatest capacity, and if deeply discharged a cell may provide only 20 cycles. The available energy on each cycle decreases.
Talking about recharging "ordinary" alkalines:
The capacity of a recharged alkaline battery declines with number of recharges, until it becomes unusable after typically about ten cycles.
Manufacturers do not support recharging of disposable alkaline batteries, and warn that it may be dangerous.
Different batteries rely on different chemical reactions. Some reactions are readily reversible, some are not. The reactions used in most alkaline batteries fall into the latter category.

@PleasureMachine
My use is xbox controller and harmony remote. I've got way more than needed so just charge a bunch when no spares left
.Similar use here. I cycle 4 batteries per controller. That way when one set dies I've got another all ready to go. Each set lasts about a week and I've been using the same batteries for ages. Go eneloops. :)
i've got 4 eneloops left behind by a coworker, 8 ladda and a bunch of AA/AAA varta that are 15+ years old. the varta were bought with a 15 minute charger. i'm surprised the batteries still function given the speed at which they were charged for many years
.
what are the best applications for rechargeable batteries?
@PleasureMachine, it seems your username checks out.
Ive found the best uses to be: Wireless keyboard/mouse, Irrigation system switches, Wireless doorbell. Seem to recharge a few times a year for each of those, so pay for themselves quickly.
These ones are not Low Self Discharge, so they are limited in use. They lose charge rapidly over time (iirc maybe 20% in the first week) even if unused. So they are best used in heavy demand applications (e.g. RC toys used often by kids) and not for occasional demand situations (emergency flashlights).
Non LSD nickel batteries are a bit… well… 1980s tech. The main benefit of these are they are cheap compared to something like Eneloops, but personally I just bought a load of Eneloops when they were on sale, and am happy sticking with those. I can keep the unused batteries sitting around indefinitely knowing they are fully charged, rather than worrying about having to throw them on a charger just before using them.
What do you mean they're not Low Self Discharge ?
The whole reason these are so popular is because they're Eneloops (ie Low Self Discharge) at a cheaper price 🤷🏼♂️
Oh, they are? I'd simply scanned the product page quickly and didn't see the term.
I'll have to try them, I could do with more AAAs and they're mentioned favourably on candlepowerforums.
for a start they don’t normally leak like alkaline batteries when they go flat and are forgotten for a while.
Rc remotes, 6x AA lasts maybe 4-6 hrs
great questions i was thinkin the same
I lost pretty much all my eneloops over years and most of them didn't ever get recharged.
Now I am not buying rechargable batteries any more.Based on that info, it's probably better for the environment if you don't buy any more rechargeables.
Not only for milly. The environmental impact of NiMH is actuall worse until you recharge them at least 20 times:
https://www.researchgate.net/publication/303599670_Life_cycl…
The key part is this:
On the other hand, for the environmental impact indicators, the picture is less straightforward, with re-chargeable batteries not necessarily advantageous
This is a rather simplistic analysis, for obvious reasons. It’s time to ditch the notion that rechargeables are “good” for the environment
@tharlow: pretty sure i'm past 50 charge cycles for most of my batteries
"Conclusions and recommendations The number of uses of rechargeable batteries plays a key role on their environmental and energy performances. When compared to disposable batteries, a minimum number of 50 charge cycles permits a robust reduction of the potential impacts for all the analyzed indicators excluding the Ozone depletion. Hence, the use of rechargeable batteries should be mostly encouraged for high consumption devices such as cameras, torches, and electronic toys"
.
Sounds like a chaotic life you lead
I think this is a common side-effect of the buy now, think later culture that OzBargain propagates. There are several problems with rechargeable batteries like Eneloops. Firstly, the voltage is too low. Secondly, Eneloops are much worse for the environment than single-use alkaline batteries (despite the marketing hype you may have fallen for). Eneloops contain nickel, which is an environmental disaster. If one considers the full life-cycle, alkaline batteries are by far the most responsible choice
But are rechargable the most cost effective option? F*@# the environment?
Only you can answer that question — there are too many variables
"The voltage is too low".
Not for devices designed to run with rechargeable batteries. You may see a few around as we move out of the 20th century.
I think I have a few 1970s walkmans and tranny radios around that don't like them.
The alkalines are a bit too low for torches compared with my 18650s…
I lost pretty much all my eneloops over years and most of them didn't ever get recharged.
Now I am not buying rechargable batteries any more.I think you need a better charger.
In 2011 when I was introduced to Eneloop I purchased Maha Powerex MH-C9000 WizardOne.
Since then I had to throw into the bin the very first set on Enveloops I bough (4 batteries) - they lasted about 10 years for me. For a reference I used them in external camera flash a lot - pretty heavy load, not just sitting in the remote doing nothing.
Every other battery I purchased since then is still usable. From time to time I test old Envelops and some of them might have 1700-1800 mAh capacity (down from 2000 mAh original) but still works Ok.
I use envelops everywhere and I used to write "batch numbers" with permanent marker (this is how I know that was the batch #1 which failed). Each "batch" is 4 batteries. But I lost count somewhere between batch 25 and batch 27…
Obviously, I am talking about original Envelops manufactured by Sanyo in Japan.Better charger doesn't prevent batteries go missing. He needs airtags.
Thanks OP. Is this a sale or permanent price reduction? Hopefully the latter

2450mAh recharge 500 times only?
1900mAh recharge 1000 times?how does it compare to Eneloop
Do you think you will recharge them 500 or 1000 times? Nah they last
I’d guess the 2450 can likely be charged more times than 500, but capacity may drop below the threshold of being considered a 2450 battery.
I thought 2450 is rebranded eneloop pro.
Is this still the caseFYI eneloop pro can be recharged 500x
Normal eneloop 2100x
https://eneloop101.com/batteries/eneloop-pro/#:~:text=The%20….It’s been a while since I read up on it… but I think it was the case that pretty much any Japanese made nimh battery came from the same factory.
Does it use same quality of components tho? (Probably easier/cheaper that way)
I'm not sure the items are the same because I notice they self-discharge at a higher rate. They are still good and are probably just a bit better than the EBLs at Amazon.
I should note that just because it comes from the same factory, it does not mean the quality is the same.
I know Quilton is produced in the same factory as the Aldi Confidence one, but the colour of the toilet paper is different.
I know the some A4 papers come from the same factory because of their forestry certification certificate, but they have different quality and shades of white.
It is also unclear whether the discrepancy between Chinese formulation of Eneloop has changed since. I would not be surprised if the Japanese factory started to cut costs and use that formulation instead… It's inevitable over time due to the consumer demanding lower prices….
@DennisLiu: Yeh I guess it depends on the cost savings from running a cheaper production line (in comparison to costs of having overheads to maintain inventory of multiple formula/components/etc)
d'oh looks like I guessed wrong on this one. Bought a whole bunch of AAA's at $10 considering all the inflation talk making it look like that was going to be the best deal for a while.
the new eneloops
IKEA charger is much better than Eneloop one, sold mine for $10 and got IKEA one for $10 lol
There are several eneloop chargers. Ikea's STENKOL charger is better than all of the eneloop "overnight" or "10 hour" chargers, but it's inferior to the eneloop "1.5 hour" model k-kj55mcc4ta.
i had that stupid one, 15 hrs charging without charger control, even had to charge batteries in pairs
I find alkaline are roughly a 100 million times more likely to leak in the device and ruin it. Never had an LSD rechargeable do that. These days mostly use them for remotes.
I've had 100 million remote controls with leaking batteries but it's never ruined the remote. We should compare our findings, testing methods and criteria.
how did use go?
I can't cheat on my Eneloop's with these.
It's complicated.
Shut up and take my money
Where you at I'll come right away.
I had ladda AAA's leak (just discovered today in my aircon remote), never had that problem with eneloops :(
Thanks for sharing that. I use NiMH more for preventing leaks than for saving battery cost. I've had too many devices die to leaking alkalines.
no probs - I was really surprised, I thought the LADDAs were rebadged eneloops but will be checking them more often now as I also use LSDs to avoid leaks
Never heard of Ladda leaks before, any other victims out there?
Yes, just found a leaker in a Brother label maker. It was one of 6 but due to the mess I had to throw 4 away (disposed of correctly of at Aldi battery recycling lol).
I’ve had ladda triple a’s leak. This was ages ago approx 6-8 years ago. i’ve since avoided ikea cells. I have a bunch of coles and Aldi rechargeable (nimh) aaa’s which have been ok.
If you charge any NiMh batteries in a "dumb" charger, they will heat up too hot at the end of the charge cycle, and build up internal pressure from the electrolyte overheating.
The pressure will rupture the over-pressure seal on the battery, which is almost always beside the positive pip of the battery, usually hidden under the cardboard or plastic disk that surrounds the positive pip.
Once this happens, the electrolyte will leak out and/or evaporate over time, and the battery capacity will reduce.
With white eneloop batteries it's easy to see if the electrolyte has leaked, it looks like there is a water stain around the positive end of the battery, under the clear plastic covering. I don't know if it will be as easily visible with LADDA batteries.
There are other ways to rupture the pressure seal, but using a dumb charger is the commonest way.
@Russ: Good to know, especially where to look for point of failure/leak. Thanks.
I currently have a smart and fast charger. Can’t remember what charger I had back then, most likely a dumb charger.
$29 delivery for 2 packs AAA & AA. Ridiculous…no thanks.
it should be free delivery?
Why would it be free delivery? Iirc Ikea don't have a free shipping threshold
I literally took delivery of 4 packs of AAAs I paid full price and ordered last week 5 minutes before reading this post. Grr!
