Not always a good idea. I'm a regular user of eneloops and similar, but recently ran into an issue with a Franklin Sensors studfinder where it would only briefly work with freshly charged Eneloops (including pros) but worked reliably with alkaline batteries.
Rechargeables have a lower voltage that isn't always appropriate. There will be scenarios where people need packs like these, just not for everyone. I won't get this pack though as I have a small number of alkalines on hand for occasional use, but understand that some people need them
I had the same issue with equipment I used regularly that needed 1.5V rather than the 1.3V of most rechargeables. Ended up getting Lithium Polymer 1.5V batteries, more expensive but have worked fine for my application (wireless mic pack). But I get your point.
Yeah, working with wireless mics taught me about weaknesses of most li-ion rechargeable batteries
@beltdrive: I tried putting 1.6V rechargeable NiZn batteries in an alarm system that had functionality in it to detect and warn when the 1.5V non-rechargeables it was designed for were going flat. It got very confused.
Alkaline battery voltage actually drops lower than 1.2v only after 25% discharge (around 500mah)
Nimh rechargeables actually has more stable throughout its discharge rate.
Check the discharge graph here

Rechargeables have a lower voltage that isn't always appropriate.
No, they don't.
You haven't kept up with what's available. You are asserting something that used to be true, but isn't any longer. Like don't leave your phone on the charger.
Yekul referred to rechargeable lithium batteries.
What you can get now are rechargeable 1.5V lithium AAAs and AAs. They have a 3.7V lithium cell with a tiny circuit board on the top which regulates the output down to a constant 1.5V. The output voltage does not fall off as the battery loses charge. It stays at 1.5V until there's no more charge left in the battery. Then it falls to zero. They can be recharged 1500-1600 times. They are readily available. And they don't cost a fortune.
Go onto ebay and look for Pallus and Kratax brands. Kratax even offers ones that are directly rechargeable. You just plug one end of the cable into a USB port and the other end into the micro USB socket on the battery.
I haven't tried Kratax or Pallus but have bought the Tenergy AA Lithium 1.5V from Amazon AU. They seem to work very well. Buy them when on special.
They haven't been reviewed, e.g. at Battery test website but the Kentli brand has.
Agreed. Rechargables have replaced most alkaline's for most usecases, but there are still niche uses for them so I like to keep a few on hand. Namely remotes, where they can last for years before needing a change.
Disposable Alkaline batteries can also be reliably recharged at least 6 times in my experience. I still this for my motion sensor bin
What happens the 7th time?
Kaboom!!!
Nah they just stop holding decent charge. Probably fine for remote controls or low drain devices but for my bin motor they don't hold enough charge to keep the bin working for a decent amount of time.
@Domingo: I bought something that looks identical to this for $20 years ago from SCA. Doesn't say it can recharge normal alkalines but it does. Many other ads for the same looking product advertise that it works on normal alkalines.
https://www.auselectronicsdirect.com.au/universal-smart-batt…
@0 0 0: Cool, thanks! Might do some research to see if anyone has a method for doing it with my Nitecore charger
Yes, they are rechargeable, but lose charge cycles quickly if taken below 60%.
So you just put the no rechargeable in a charger? No special gadgets or method needed?
You need an alkaline charger because alkalines run 1.5v nominal vs NiMH or NiCd which are 1.2v. Putting a 1.5v battery in a 1.2v charger probably won't work or do anything.
Also only try charging alkalines and not other cheapo disposable batteries that use different chemicals. They won't recharge or not well. Usually Everready Heavy Duty batteries are crappy non alkalines
OP specifically mentioned those toys 😌
Ain't nobody wanna caught in need of charging eneloops while about to use those toys 😏
Under 30 single OzBargainers think "those toys" means sex toys.
While Ozbargainer parents know it means those ultra-cheap junky kids toys you don't want to risk putting your pricey eneloops in, in case they get thrown away. 😂
Under 30? Speak for yourself lol
And blood pressure monitors lol
I read via Consumer Reports that "rechargeable batteries are more sustainable than disposables only after you’ve used them at least 50 times."
I therefore have a mix of types and don't put rechargeables in long use items, e.g. wall clock
That's a really weird stat. Look at the volume of 50 dead batteries versus a single rechargeable and it is hard to imagine any situation where mining, processing, manufacturing, transporting and disposing that extra volume would be sustainable.
Perhaps they were talking about a specific aspect like water used in manufacturing or counting co2 from recharges in mains power against the lower co2 emissions from sourcing the materials in disposable.
I expect the figures come from the mineral sourcing/extraction process. Recharge batteries have Lithium, most standard Alkaline batteries do not.
@anonywhy: That is applicable to the LiPO cells in a phone or laptop, but Eneloops etc. are NiMH:
https://en.m.wikipedia.org/wiki/Nickel%E2%80%93metal_hydride…But even alkaline batteries are zinc and manganese based and I would be surprised if there is a 50 times difference in manganese and zinc to other metals like lithium or nickel.
It's not a made up stat: https://link.springer.com/article/10.1007/s11367-016-1134-5
For the impact categories Acidification, Human toxicity (cancer effects), and Particulate matter, an “inefficient” use of the rechargeable devices (for only 20 charge cycles or less) could cause higher impacts than the employment of disposable batteries.
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.
Moreover, for the Ozone depletion, NiMH batteries are hardly environmentally better than alkaline batteries even with 150 recharges.
@bio: Understood, but that is if the batteries are incinerated at end of life to produce ozone and particulate impacts.
These aren't the case if they go to landfill or are recycled.The table of comparative impacts show rechargeable winning in all other categories, so if you recycle or landfill dead rechargeables they will always be more sustainable, even for a small number of cycles.
Not sure why I'm getting negged for sharing a fact. I'm big into recycling etc but it's good to know the whole picture and when to use certain batteries. Here is the report:
https://www.consumerreports.org/electronics-computers/batter…I didn’t neg, but I am interested in this.
The full study mentioned by consumer reports was in Italy.
The paper can be downloaded here:
https://www.researchgate.net/publication/303599670_Life_cycl…It makes a bunch of assumptions, which cannot be avoided in this type of study, and was very thorough - for example it considered packaging, transport from the factory, impact of a car trip to buy the battery (in amongst 20 other grocery items, not a single trip), the resources and waste of a charger, and the way the materials are recycled or disposed (30% recycled, 70% incinerated as waste).
It made two assumptions and a comparison that I think undercut the conclusions.
The comparison was the number of charge cycles before a battery was disposed. This was modeled on 20, 50 80 and 150 charge cycles. It supposed some people are tossing functional batteries after 20 cycles which seems low to me.
It also assumed the charger would be replaced after ten years, having been used twice a week. So about 1000 charge cycles, which seems low to me.
And most importantly for us, it assumed the 70% of waste not recycled would be incinerated (as is common in Italy).You can review the results in the paper. There were two areas where alkaline batteries were much less polluting that NiMH rechargeable, one was Ozone depletion, the other particulate pollution. In all other cases (energy, water, climate, ecosystem) the impact was lower for NiMH even at 20 cycles.
The particulate and ozone failures are because the batteries were assumed to be incinerated when diverted to waste. In Australia, waste almost exclusively foes to landfill. This removes that difference.
So I am pleased that my instinct that a substantial volume difference was a good rule of thumb, and even for batteries only recharged a few times it seems rechargeables are more sustainable if disposed of suitably, and doubly so if you recycle all your batteries.
It supposed some people are tossing functional batteries after 20 cycles which seems low to me.
I think that's the point. They are ok if you charge them 50+ times before you discard them. I personally do, but it's hard to guarantee that if they are used in a (children's) toy where they can be easily lost, therefore I use alkalines in such devices.
It also assumed the charger would be replaced after ten years, having been used twice a week. So about 1000 charge cycles, which seems low to me.
My experience with different types of chargers agrees with this. My 10 year old La Crosse BC1000 died last year, so there's that.
@bio: Did they have assumptions on whether the charger was incinerated/landfilled or recycled?
I'd take mine to eWaste, though I'm not confident that 100% of it wouldn't find its way to landfill anyway if there's no particularly usable parts…
I say this having fried a BC-700 by accidentally plugging in a 12V brick well before it's 10y assumed life…
Thx op, got for emergency times in cybertruck
Thanks, will keep the wife happy… for her mouse
What's the DPI setting for her mouse?
Maxxx
PS/2?
Serial. Sometimes parallel.
Thought was a good deal until saw it was $23.58 in Feb this year. Seems like all the prime deal battery prices are higher than previous sale prices this year. 72 AA pack is the sale price for what they had the 100 pack for previously
THANKS! got some AAs too
Don't abuse the planet.
It has suffered enough.
Buy rechargeables.
At some point we've got to stop with this buy it and throw it away culture.
Or recycle the batteries???
Sure, but how many of them do get recycled.
And how much energy and materials are wasted recycling and recycling and recycling. You can get 1.5V lithium AAAs and AAs that can be recharged 1500-1600 times.
I’ve still got rechargeables holding great charge that are over 15 years old. This is the ozbargain way.
Show me a data sheet of lithium cell that can take 1500 cycles. Without specifying the capacity loss that statement is as good as worthless. Even the best chemistry would struggle to achieve that with any meaningful remaining capacity.
1500 cycles with 99.9% capacity lost. Puts that different into perspective.
I also wonder if the charging circuit and buck converter could take the number of cycles.
There are too many of these questionable lithium AA/AAA/9V cells on eBay and AliExpress, but without some half decent community reviews it's very much a buyer beware situation.
I also like how Pallus measures capacity in mWh. They claim 3500. Maybe your average punter would think 3500 is bigger than an AA NiMH claiming 2500. Bigger the better right, and mAh and mWh seem similar….I wonder if that's 3500mWh @ 1.5V or 4.2V. Straight off the bat Pallus claim two pieces of information with a key part left out. I would say it's 4.2v as that's usually the standard, and at 1.5v would be unbelievable power density for a AA.
Oh and 3500mWh, sellers on eBay and those other places (AliExpress) have never been known to inflate the specs. ;-) Buying no name brand cells, especially lithium from eBay is a great idea, what could go.
Until the big players go into this space, or maybe a liitokala, vapcell type company, someone that's less likely to fudge specs, I wouldn't be buying too many cells without solid community reviews.
@mrhugo: Scepticism is good. Especially scepticism of specs claimed on ebay by Chinese suppliers.
at 1.5v would be unbelievable power density for a AA.
Isn't that the point of lithium ion chemistry. The whole reason it has been adopted as widely as it has. Because of its high energy density.
And when has innovation ever come out of the big guys in any industry?
Tests on the Kentli Lithium 1.5V rechargeable shows it meets the claimed 3000mWh. These claims are at the actual output voltage, 1.5V.
On the comparator on the LYGTE website, Eneloop Pro 2450mAh also tested at close to 3,000mWh. (AMp-Hours is different).
So the Kentli delivers the same energy as Eneloop Pro but at 1.5V instead of 1.2V.
Haven't seen any independent testing of the Pallus and Kratax brands.
Also, cannot vouch for the cycle life of these batteries. I have been using the Tenergy brand bought from Amazon AU but nowhere near even 100 cycles so far, but so far, working well.
Re-use (ie rechargeable) is better than recycling
In a perfect world, yes, this is what should happen.
It doesn't though.
Stupid reason to neg the post. I’m all for recycling and rechargeables but this is ozbargain, not save the planet.
You driving a full ev?
Solar panel off grid?
Fully recyclable/biodegradable clothing head to toe?
Using public transport at all times?
Making sure e-waste is recycled?It's a bargain website, people vote with their wallets. 100 batteries vs 4 recyclable batteries that cost the same as this. If you have kids and toys, half the time I guarantee you batteries are getting destroyed or lost, I'd rather not pay a fortune on those.
If you have kids and toys, half the time I guarantee you batteries are getting destroyed or lost
Simple, just don't have kids!
just don't have kids!
As someone pointed out, the best thing you can do for the planet is have one less kid. Because that's one fewer human consuming resources.
@GordonD: I mean, there are other ways to have fewer humans consuming resources than having one less kid (less than what btw?). But most of those will land you in jail…
I agree with your message, but OzBargainers as a group would be one of the biggest owners of rechargeables in Australia. It is basically a rite of passage/expectation to buy Eneloops!
All I see on Amazon is plastic garbage trinkets. So much cheap crappy Chinese products for our hyper consumerist culture. It's so depressing. So many people buy utter crap they don't need.
Any deal for the AA?
Just drink less.
Buy rechargeables
They both have their places. Rechargeables need to be recharged at least 50 times to be enviromentally friendlier than alkalines. That is simply not possible if you are using them in, say, remotes. Similarly, kids lose their toys, leave them in the rain etc. all the time, so that's not feasible either.
For all other types of devices, sure, just buy Eneloops.
Where is the deal?
Gotta get a good deal on rechargeables !!
Hopefully Eneloops or Ikea come to the party this PrimeDays/Black Friday sale.Too many keyboard eco warriors here happy to vote with their negatives but probably destroying the planet in other ways.
Hope you also live off the grid and use rainwater too and grow your own food to eat and are on the vegan raw foods bandwagon as well.There's a place for both disposable and rechargeable batteries.
To the people saying buy rechargeable, I get it, but there are some circumstances when its best not to (for me). I.e young childrens toys.
Half of the battery toys my kids play with inevitably end up in the shower, bath or left outside in the rain, and get rusty as hell. The other problem I faced was my wife throwing away broken toys with my beloved eneloops pro's in them which were worth more than the toy.
Yes! I use to add eneloops in SOME of the kids toys… and always forgot which toys had them vs not. They could be in there for years at the bottom of a bucket never to be seen again.
Don't cheat on your Eneloops
experienced buying bulk from Aldi batteries, where most of them are dead
. Can't say about Amazone one thus might be good who knows.From the last batch I received there hasn't been a single bad one out of 48 of them, that includes most of them been on the shelf for 3+ years too
Great to see Amazon is backing up their committment to sustainability by encouraging the sale of single use batteries. Greenwashing at best.
Negged the last deal and negged this one too. Despicable.
Thanks for sharing. Like I said, too many keyboard warriors who are happy to vote but probably are hypocrites in other ways.
Hope you're using rechargeable batteries in every since device in your house. Yes, even the small button batteries in your key fobs, etc can be replaced with rechargeable batteries.Well many of these come standard with non rechargeable batteries, so not much you can do. There's a huge difference between having a small slow discharging non rechargeable battery in a fob and buying 1000 AA batteries that can easily be substituted wirh rechargeables.
There’s only 100 in this pack…
@UncleRico: It's a figure of speech. Like when you say "I bet that bloke has had a thousand beers at the pub".
@Lets Make Sandwiches: Which bloke? I don’t know anyone who could have that many beers at the pub, or any other place…
@Lets Make Sandwiches: I apologise. I know that exagerrating beyond belief to make a philosophical point must frustrate you…
Every AA or AAA battery device comes standard with no batteries or disposable ones with the exception of things like old cordless phones or baby monitors. So what's your agument for only using rechargeable batteries for AA and AAA devices and not your car remote, garage remote, etc.?
Hypocrisy and eco warriors of convenience…
@0 0 0: Your question makes no sense. My argument for not using rechargeable in fobs etc is because they already come with batteries and don't need replacement due to slow drain. For items that take AA or AAA I use rechargeables.
eco warriors
What does this even mean ?
People trying to reduce waste and consumption are just … normal people.
There's nothing "warrior" about acts of common sense 🤷🏼♂️
Meh. Single-use can have their place, but these are rubbish. I've got a good range of Amazon Basics gear which typically represents good bang for buck, but these are aweful.
I predominantly use Eneloops - like every other Ozbargainer - but have used these in the past, alongside Energizers which often go on sale at half price on Amazon.
Anecdotally, both the AA and AAA Amazon Basics range have around half the lifespan of Energizers. Give them a miss…
They work just fine. Have had them since this time last year and still using them.
In Europe, kids have been taught in school since the early nineties that disposable batteries are bad, and to use rechargeable instead. I couldn't believe the widespread use of disposable batteries when I got here over 20 years ago, and it's crazy that it is ongoing.
Good deal - decent batteries. thanks for posting.
How this deal turned into greenie drama is beyond me.
They always looking for an in.
what's "greenie drama"?
What is the expiry date?
Waste and waste of money.
Buy rechargeables once for each device and forget.
No need to refill, re-order, etc. just recharge at home and you're done.
The rechargeable batteries most likely will outlive your devices (esp. toys, consumer electronics etc.)Cool. Post a bargain on rechargeables
Time to upgrade mate as the good ones are all rechargeable lithium now…
