Thanks bought one each. I would expect they'd maybe be about the same as Varta that I usually get
I dunno, practically top all the independant tests ive seen (at least 4 different sites); if we have a new king at this price, thats gonna be pretty amazing :)
Woo, get some fuse wire and make your own Tesla battery
So much landfill… Amazon also sell rechargeable, and they are pretty decent.. use them in all Xbox controllers, after about 5 recharges they’ve paid for themselves
This, I really didn't hink there would be this much love for disposable batteries from such an eneloop loving audience
too much landfill
Well said… Captain Planet, away!
Ozbargain, where buying random cheap junk is praised but buying disposable batteries to power the cheap junk is too wasteful…
How far can I run an Electric Car on this and how many do I need? lol
About 10,000 Elon
Thanks Op, got 1 of each too.
Thanks op! Should take care of my battery needs for 2022 lol
I wonder if I'll get the usual 3 recharges out of these before they drop below 50% capacity, like I do with Varta and Energizer so called 'non-rechargable'.
We shall see!
Even if they survive 1 extra charge to 75%, thats one hell of a saving in total.
You can recharge 'non-rechargable' batteries?
Interesting, I have the identical charger as it was sold here branded by SCA, from memory the manual says its only meant to be able to recharge "rechargeable alkaline batteries". I took that to mean not normal alkaline, at the time I was a bit disappointed. Is this guy just risking exploding his batteries?
@Jackson: I don't mind if the batteries break their seal, they'd be dead anyway, and I charge them somewhere that an acid leak isn't going to be a problem (glass tupperware).
Lots of those guides try and go from zero to max again, and they're just not designed for that.
At 0.2C rate, and 4 hours, I haev some AAA batteries on their 10th or 11th cycle, being used in my headphone amplifier.
@MasterScythe: I've still got my old ReZap
Most success was had with Varta cells, I found other brands would end up leaking either in use or in storage.
I seem to remember it recommending topping up lightly depleted batteries rather than trying to recharge flat ones.
Yep, so long as you don't try and put more than 75% back in, and do it at a nice slow rate.
I usually use 0.2C for 4 hours; since the charge process is a little lossy, it equals out to about 72-76%
Yes, some non rechargeable batteries can be recharged if you do it slowly (10-20mA) and don't try to put too much charge back in. Unfortunately, I got a little bit greedy with a few batteries and recharged them too quickly (with around 200mA current), and they started leaking…
With all the Eneloops that Ozbargainers hoard why do we need these?
Some devices won’t accept NiMH and need alkaline.
Lol
Like what?
Insulin pumps for one
I have a bunch of electronic test equipment such as multimeters and LED testers that won't function with 1.2V rechargeables. They require battery changes only every 5+ years or so, so luckily don't churn through batteries.
This is cheap but if you go through this many batteries, you really ought to consider rechargeables. Get on the ozbargain eneloop bandwagon.
People should still have plenty from when Dick Smith was around.
I do still have a few, but they are a bit long in the tooth. I keep them around in case I get desperate between charges
I have over a hundred from various dick smith deals, lost count ages ago, but they’ve certainly come in useful once I had two kids, so many kids toys chew through the batteries. That and all the motorised lego technic sets I’ve accumulated over the years as well. Very useful to have them still running without needing to swap the batteries out or leaking
Some of us got on the bandwagon too late. I also think the kids might not have known some of our batteries are rechargeable and thrown them away.
All my Dick Smith ones leaked :(
Yep most of the DS ones I had leaked in storage
100% but there is use cases where you can't utilise rechargeables, my wife's insulin pump doesn't work on rechargeables, contacted the manufacturer who also confirmed it
Probably 99 % of common uses will work with rechargeable. I haven't come across anything that won't work.
Electronic test equipment, medical equipment, some radio equipment, some kids toys don't work with NiMH for lots of technical reasons.
Most medical gear is deliberately designed for alkalines, as NiMH rechargeable cells have a particular characteristic where they go flat without warning, which can be dangerous. They supply almost full voltage when nearly flat, then suddenly can't supply enough peak current when needed. Alkalines have a more predictable discharge curve.
Most AA or AAA stuff built 15-20 years or so works fine with NiMH rechargeables, but unfortunately things that require AAs are becoming scarce. I love stuff with replaceable 18650 cells though! Endless supply from old laptop batteries. I've converted everything in my house that has physical space inside the case to 18650.
Most of the landfill products produced today have non-replaceable internal rechargeable cells that die after ~5 years even if you treat them well, or die after six months if you don't charge them in time. It's tragic.
Great deal. Somehow Amazon gave me 11-ish discount, making it <15 bucks.
Thanks OP.
Can you not
Cheaper getting rechargeable batteries that will last hundreds of charges and help reduce landfill.
I do agree with you, but just be alert that rechargeable NiMH batteries don't work in everything. Even worse they sometimes appear to work but then fail randomly when the batteries can't supply enough current.
I've seen hundreds of dollars worth of equipment thrown away because it 'stopped working' when the owner tried rechargeables, and didn't realise it was because the stuff absolutely needed alkalines.
Sending perfectly good equipment to landfill is arguably far more wasteful than replacing a non-rechargeable AA battery every 5-10 years. And most new products come with non-replaceable internal batteries. It's very sad.
I wonder what the end date on these is.
wonder how long these will hold charge..
10 years
These are 1.5v
Rechargable battery 1.2v
4 non rechargable batteries in series = 6v
5 rechargable batteries are required to get the same voltage, therefore, rechargable batteries cannot be used instead of these
Absolutely not correct, try it yourself.
New Alkaline batteries start off at 1.5-1.6 volts, but when they are 90% used the voltage drops to around 1 volt.
Rechargeable batteries start off at around 1.4 volts, and when used the voltage quickly drops to 1.2 volts. However, the voltage stays at 1.2 volts until it is around 90% used. Therefore, if your device can still run on alkaline batteries that are 90% used then it can definitely run on rechargeable batteries.
You're correct, just keep in mind that some NiMH cells can't provide the same amount of peak current as alkaline cells. If stuff keeps randomly failing or only 'sort of' works with rechargeables, it might need the higher current that Alkaline provides.
But yeah most well designed stuff works just fine, sometimes even better, with a good set of Eneloops. I'm so happy battery technology has advanced this far! We just need to stop producing landfill with non-replaceable batteries.
That's incorrect. NiMH cells typically have an internal resistance of 30-100 mΩ, while alkaline cells typically have an internal resistance of 200-300 mΩ. The internal resistances will increase as the battery is discharged. If stuff keeps randomly failing or only 'sort of' works with rechargeables, your rechargeable battery is either dead, or has degraded to the point where it's unusable, or the battery was a fake / bad quality.
@AwesomeAndrew: Thanks for the info AwesomeAndrew.
I was basing my knowledge on early technology NiMH high self-discharge cells which in my experience often appeared to work but then suddenly failed when using very old equipment designed for Alkaline. Any number of things could have gone wrong in that situation. Chargers were pretty basic twenty years ago when I started buying NiMH cells, so I'm sure a lot of my cells were prematurely damaged too.
I'm not familiar with the newer slow self-discharge ones. I really should update my knowledge and do some more reading, and buy some new Eneloops to test. Already have a modern charger that shows me internal resistance, which is great for diagnosing bad 18650 cells. I'm off to https://lygte-info.dk/ to do some reading.
EDIT: I might also be thinking of the problem Lithium Ion cells have when they get old, where they can't supply full current. That's what was happening with iPhones for a while, so Apple were throttling the speed to limit current draw. So yeah, my old crappy cells were probably the issue.
Looks like the AA's are gone.
I bought 2x 48 packs of AA
Yeh saw those, not too bad but not as good as the 100 pack.
My fault for waiting, was going to go halves, by the time they got back to me were gone. Buy first, ask later 😄
Hoping they'll come back.
I've got a one year old. Everyone keeps giving us toys that need batteries. Shame they don't do D size batteries too
Have the AA sold out?
OOS for the AAA version too

Better to just by rechargeable batteries to reduce environmental impact and waste?
or officeworks
Really a no brainer to buy good rechargeable batteries like Eneloop. I literally haven't bought any alkalines in the last 40 years, and I don't have worry about running out. PS I discharge before charging, I'm still using a couple of 40 year old rechargeables.
