I had to click on the alternative sellers to see the price
"May be available at a lower price from other sellers, potentially without free Prime shipping. "
CamelCamelCamel.
I know this is cheap and I hate to say it but does the price reflect the environmental impact. Go rechargeable surely.
Rechargeables have 28 times less impact on global warming, 30 times less impact on air pollution, 9 times less impact on air acidification, and 12 times less impact on water pollution.
Grosso said that if a battery is recharged about 50 times, its overall benefit is significant. But if it’s used only a few times and thrown away, its impact is worse than a disposable.
Depends on usage mate, most people aren't recharging the batteries hundreds of times anyway.
@dowhatuwant2: Why would someone only use them a few times and then throw them away?
What a weird argument.
@Ryanek: If you put rechargeables in your TV remote for example, it's going to be several years before they need charging.
You're certainly never going to hit 50 recharges on those batteries.
@Ryanek: Because people need batteries for lot of things and some of them only need very low amounts of power so they wont get charged often enough to be worth it. Your take on it as a black and white thing is ignorant.
@Ryanek: Losing batteries, having batteries fail. or worse, having relatives who throw them out because they dont know they're your precious ozb currency…
@dowhatuwant2: What idiot uses a rechargeable a few times and throws it away? They are used in everything, even if you stop using one device you just use it in the next
Except for that time I got Varta rechargeables and they look exactly like the alkalines and someone inadvertently chucked them
@greennick: Because you can buy 4 Ladda AA batteries for 12 bucks on special and you can recharge them 500 times (according to the packaging), which is the equivalent 2000 batteries. That's 20 times the batteries for half the price. Unless you need to use the batteries all at once it's way better.
and you can recharge them 500 times …
And to achieve that you're going to have to completely empty and recharge them every week… for ten years. How often do you think that happens?
Firstly at 1.2v they aren't suitable more many applications. Most of us probably drive a diesel. Far bigger issues currently
Alternatively, you can be thankful and appreciate the fact that some people care about something other than their immediate needs.
Selfish ducks usually do that.
Destroying the planet to own the libs
You sure are owning those environmentalists.

Every time someone makes a comment like this, it makes me want to submit a deal for a PS5 at RRP.
To be fair, that was a good one.
Amen
What rechargable do you recommend? Looking for a set with charger.
Eneloops go on sale often and another Ozb's favorite the Ikea Ladda's
Just pick up an eneloop kit next time on sale
Some of my eneloops are close to 10 years old and still going
How many times do you estimate you have recharged those ten year old eneloops?
@trapper: Back in the day probably close to once every few weeks , depending if I had any photo gigs on. Used to use them in my Nikon sb600 flashes. When I dropped photography as a side gig I basically relegated them all to random things like game controllers, tv controllers, etc
Still use them mostly in my Xbox one controllers which I prob change once every 5-6 weeks (don’t play much these days)
The Duracell duralock green ones (the expensive ones).
They are worth it - I saw some voltage profiles where a guy did a test and they were almost identical to eneloops. They are either rebranded eneloops or made damn similar.
They're the only rechargeables that work well in my kids toys with a pretty big draw.
charger is the most important for battery longevity, need one with over charge protection so it stops charging as soon as batteries can't take any more electricity
for batteries the ikea ones are hard to beat for value even at rrp, ikea charger isn't terrible but one from liitokala is better - you can usually find a 4 bank one for around about $16 on ebay
True, but you need to recharge them quite a few times before they become environmentally more friendly:
Disclaimer: All my AA and AAA batteries are rechargeables.
Researchers encourage the use of rechargeable batteries mainly for high-consumption devices such as cameras, flashlights, and electronic toys, which require frequent recharging. Batteries charged less than 20 times do not diminish pollution problems such as ocean acidification, human toxicity (cancer effects), and particulate matter more so than their single-use cousins, and may even contribute more to ozone depletion unless they’re recharged around 150 times.
Can you share the source? Would be interested to read more.

Here you are. 20 recharges to be better in most metrics, 50 to be clearly better in all ways.
Rechargeable automatically better and if you're just blindly shoving rechargable batteries into low power devices you're actually increasing your environmental footprint.
To be honest i didn't realise the break even point was so high. I'm probably going to use less rechargeables now for low power applications. Don't forget that many recharables lose their charge through time much faster than disposables as well.
@Ezuku: I think given that for climate change, it's not much of an impact (certainly not on a global scale) but for waste generation, you only need 20 cycles to make -90% impact, they're still the preferred choice.
My primary goal is reducing waste generation, so this is fine.
It doesn't look to me like the impact of the waste generation was examined that closely? Not gonna pretend I can decipher these papers super well though.
@Ezuku: I've had a quick read of that paper, and many of its assumptions are wrong.
Example 1: they give an AA NiMh capacity of 1.9 Wh. For ordinary eneloops, it's 2000mAh x 1.2V = 2.4Wh. For eneloop pros, it's even higher.
Example 2: they discount the fuel used to drive to the store, by assuming you are buying a total of 20 items, and allocating only 1/20th of the fuel used to the batteries. In this very deal, it's being delivered by Amazon, as a single item. So roughly 20 times more fuel used than their estimate, and maybe more if it was delivered from a large car or a truck. However, if you use an Amazon delivery point, the car/truck might be delivering 20 items to that delivery point. But there's a fair chance you are still driving to the delivery point, and probably not buying/collecting 20 items from the deivery point, given that many of my local delivery points are petrol stations and chemist stores.
I prefer rechargeable battery but my understanding is that some devices like smart locks should use alkaline batteries. (I do not know the reasons.)
This is correct, I want to go rechargeable but my samsung smart lock does not work with them (Or atleast not with the Panasonic Eneloop Pro's).
If it had rechargeable ones that it worked with I would go to them.
Rechargeable only capable of Max output of 1.2V vs 1.5V for non rechargeable
@Indomietable: There is a different rechargeable chemistry that gives 1.6V - Nickel Zinc. Hard to buy in Australia, and they require a different charger to NiMh chargers.
Example NiZn batteries and charger: https://www.amazon.com.au/melasta-Rechargeable-Batteries-260…
to do with self discharge rate?
They're different with different uses. Heavy usage that's going to be recharged many times? Go rechargable. Only going to be used very occasionally? Disposable has a much lower impact than a rechargeable battery recharged only once or twice.
https://www.researchgate.net/publication/303599670_Life_cycl…
Not too mention the very specific uses that require disposable batteries as they're not fully interchangeable.
Rechargeables dont work well in some devices. Plus whos gunna use enerloops for kids toys?
All of my kids toys have Eneloops, that's the main reason I switched to rechargeable
Yep me too, and more than half have accidently been thrown away :-(
That’s not a real place.
While I agree with you and I use rechargeables for many things, there are some devices and applications where rechargeables are unsuitable.
So this deal is suitable for those use cases, so I personally wouldn't neg it.
Also you can recycle non-rechargeable batteries and all of mine when used get put into a container which I drop off at my local Officeworks recycling bin.
https://www.officeworks.com.au/information/about-us/peoplean…
Silly reason to neg a deal. This is ozbargain not green-bargain. Non recyclables have their use cases and not everyone wants to use rechargable for everything, plus there are battery recycling drop off points all over the place.
ozbargainers should have a lot of eneloop
I still have a lot from DSE
Bought all the way back from 2012?
Bought all the way back from 2012?
During Dick Smith closed down.
For me, there are some infrequent times i might need batteries (random kids toys) and don't want to use eneloops. I save eneloops for stuff with frequent battery changes only.
1.2V vs 1.5V. Do they last as long as alkaline?
Nimh rechargeables have around 1.5x greater energy capacity than alkaline batteries.
Do they last as long as alkaline?
That depends on the characteristics of what you're powering with the batteries. Alkaline batteries cheat a little, by calculating their capacity while discharging down to 0.8V per battery. So four alkaline batteries, as a pack, have a "fresh" voltage of about 6.4V, and a "flat" voltage of 3.2V.
NiMh batteries start at about 1.3V and are dead flat at 1.1V, so in a pack of four, that's 5.2V fresh and 4.4V flat.
So if your device works fine down to 4.4V, you'll get more mAh from NiMh batteries. If you use alkaline batteries, roughly 1/4 of the battery capacity can't be used by your device.
Sometimes alkaline batteries are better. I have a camera that I suspect regulates the four AA batteries to provide 5.0V, so the pack of four NiMh batteries can only drop from 5.2V to 5.0V before they are too low to be of use. While four alkaline batteries can drop from 6.4V to 5.0V, giving a significantly longer life. Non-rechargeable lithium AA batteries, with their very flat discharge curve, give even longer life again, as a pack of four will stay above 5V for almost their entire discharge curve.
Logitech computer mice that run from a single AA battery, are an example where there is no disadvantage to using NiMh batteries. They run down to 0.9V, so you'll get the full capacity from a NiMh battery, and a little under the full capacity from an alkaline battery.
Thanks for the valuable information. How do you know the cut off for each device? Is there a register where you can check? Or is it a case of testing the residual charge in the battery once the device stops working?
How do you know the cut off for each device?
In the case of Logitech mice, it's because I asked their technical support. Took a couple of tries, but they came through in the end. I wanted to know if all Logitech single-battery mice play nice with an NiMh battery installed, and Logitech said they do, and told me the cut-off voltage. I don't know about their mice with more than one battery.
For other devices, test it yourself. Start with flat NiMh batteries. Charge them for five minutes, so they'll be at the "almost flat" charge level. Then put them into the device you want to check, and see if it works adequately.
When you are flattening your NiMh batteries before this test, make sure you flatten them individually, e.g. use a flashlight that takes only a single battery, and flatten them one at a time. Or use multiple single-battery flashlights to simultaneously flatten multiple batteries.
The reason for flattening the batteries individually is this: if you have more than one battery in a device, and you run it until the batteries go flat, one battery will invariably go flat before all the others. But the device will probably continue to draw power from the remaining batteries, and current drawn will effectively be reverse-charging the battery that went flat first. This is a very bad idea, reverse-charging batteries is harmful to them.
If you flatten a battery in a device (e.g. flashlight) that only takes one battery, the worst that can happen is that the battery goes to zero volts, which doesn't harm the battery. Reverse-charging is not possible when discharging in a single-battery device.
Also, as you appear to be a beginner with NiMh batteries, be aware there are two types of NiMh battery:
Also, if you don't already have a charger, get yourself a smart charger. It's often hard to tell which chargers are smart chargers, some (like Ikea's STENKOL charger) claim to be a smart charger but barely qualify. The STENKOL charger is particularly bad at detecting when to stop charging the batteries. If you see a charger that looks good, read old deals for that charger here on OzBargain, usually I or someone else knowledgeable will have commented on it.
@Russ: Thanks for the great info there! I was about to buy some cheapies of amazon which I think were the 'old type' based on reviews. So you already saved me there.
One last questions please…. is this a smart charger? https://www.amazon.com.au/Eneloop-Rechargeable-Battery-Charg…
EDIT: looks like it might not be 'smart' based off reviews. Is there a good cheap one you can recommend please?
@Stivo: Good smart chargers usually start at about $30, rarely are they cheaper.
Panasonic make a good smart charger that looks just like the one you found, but the model number is k-kj55mcc4ta. It only comes with four batteries. It only has lights to tell you when charging is finished, it won't warn you when the batteries are starting to fail.
Smart chargers with test mode and a numeric display of battery capacity will let you know when batteries are starting to fail. Such chargers usually start at about $40, and I recommend the Liitokala Lii-500. But be careful if you buy that one, many sellers with low prices are selling the unit without the mains plugpack. Also Liitokala only make this charger with EU, UK or US plugpacks, you'll need a mains socket adaptor so you can plug it in.
dont hit me with a stick but the pic looks like the majestic Temple of Kukulcán in Mexico
Angkor Watts
Hahahahaha
Anker Watts
is that normal not to publish capacity (mAh) value? is it same for all non-rechargeable ones?
Yeah it's annoying. Someone should do the drop test on these :P
I asked in a prev deal a while back if someone had tested Varta's and someone did know, but I don't remember the number … (except that it was quite decent enough I'm happy to stick with them for my clocks and remotes)
These have been tested by HKJ, probably a vast majority of cells have been tested. I think these perform about the same as the Varta AA.
https://lygte-info.dk/review/batteries2012/CommonAAIndividua…
Good price but, for me, they would have expired before I got through 10 batteries.
Edit. Nevermind. 10 year shelf life.
Sorry but this is terrible for the environment as they are not recyclable just spend a tiny bit more and use eneloops or laddas plenty of bargains on them.
I thought the ozbargain community loved rechargeable batteries l, these posts should be moderated IMO
completely agree. Only justifyable use for non-rechargables i can see is when the battery is being used somewhere that it may get stolen (such as in an airbnb, or public location), OR when it's something that the battery MIGHT outlive the product itself, like a TV remote.
Every other case, i'm sorry, go rechargable.
There are applications where recharges are not suitable.
Geez…. "I don't have a use for them, so no one else does either."
where
Wrong, you need to learn more
i have a automatic sensor bin - when i use eneloops/laddar batteries. the bin lid does not completely open. when i use non rechargeable it opens fully.
the rechargeable are only 1.2V. Non rechargeable are 1.5V.
I agree with the sentiment but wouldn't like to see moderation based on environmental impact. For example plenty of deals about where you save money by buying from your overseas rather than buying local which has it's own carbon footprint/impact, should they be moderated?
If they're not recyclable why do Bunnings and all the other stores with battery recycling bins take them in?
You mean like households recycle plastic and glass and they just go to a warehouse somewhere…
They're not for recycling. They're for safe disposal!
Reduce comes first
At 1.2v do they last as long
It isn't that simple.
A lower voltage doesn't mean it will store less energy.
A carbon zinc battery aka "heavy duty" AA is still ~1.5V but if you stick them in something like a digital camera you used to only get a few photos before they went flat. They store very little energy. A NiMh at lowver voltage would last for ages.
Some devices require a higher voltage though and will cut off once the voltage gets below a certain level. In those situations the NiMh will not be flat but the device will turn off anyway.
Non rechargeable batteries are actually recommended for most low discharge uses as rechargeable batteries take a lot more resources to make. Do your research before you neg a deal. Posts by ignorant people should be moderated more than anything.
These batteries are terrible. Put them in a smart scale and they kept going flat after one day. Energizer etc don't have the same problem
When will Amazon bring back their Basic rechargeable batteries again?
I've had these before. Cheap…but cheap for a reason. Don't keep charge well. Shelf life is garbage and use time is considerably less than the more known brands.
Yeah if they're anything like the cheap aldi batteries, those literally last like 4 hours in an Xbox controller, whereas the initial batteries it came with lasted about 40.
Never had an issue with Amazon Basics batteries before, have been using some for over a year in various applications and havent swapped them out yet.
Thanks, always need spares of these
Thanks op
Go rechargable. Cheaper over the long term, and less bad for environment.
Not worth promoting if the batteries are no name and fail soon
I do have a lot of Eneloops and use a Lacrosse charger. I must be doing something wrong. I think I'm charging them correctly but I can never seem to get good life out of them vs normal Alkaline battery. Using them mostly for kids toys, slot cars. Or is it known that they don't last as long?
Does your charger have a charge/capacity measurement function?
Sounds like you cold be using eneloop lites - could very well be fake eneloops too. I've had fake batteries that hold like quarter of the charge of what it should have been.
Omg. The simping for the enviort is insane. I'd like to censor all the international flights and cruises as they cause so much pollution. Infact. This website should only show fruit seeds for local pickup by bike
Awesome….these are great to give away with kids presents which require batteries.
People negging for 'environmental impact' and saying they are not recyclable need to get off their high horse. People don't always want to use rechargable batteries in absolutely everything, and there are battery recycling drop off points which do take these type of batteries.
Beat me to it - pretty good deal! Probably all time low?
