Yeah i forgot to say. It's in the Coles catalogue which starts tomorrow 15th March for $3.65. But who's going to argue over 5c?. I mean just saying it's a deal for those who aren't any where near a Bunnings.
Thanks for that hollykryten. Looks like Bunnings didn't want to get done on a pricebeat. May as well add it to the post for the benefit of everyone. Credit given :)
Are these better than standard Alkaline?
The AAA batteries - 8 pack are also on sale for $8.07.
You'll be able to Pricematch that at Officeworks too
Are these Ultra better at not leaking than the regular Duracells?
I usually buy Energizers as I've never had any leak - but Duracells (especially AAs and AAAs that come pre-packaged with devices - e.g. mice) often end up leaking after a few years.
I've had the same experience as you with Duracell batteries leaking. I even had one explode inside a wireless mouse which ended up ruining it. Stick to Energizer or any other brand.
Now that I think of it, same. A couple times had Duracells in my old high school TI-83 that leaked (albeit my fault due to leaving them in there for years) but I can't recall any times I've found Energizers in other old devices leaking.
Yep, stay away from DuraLeaks.
True I have experienced leakages with Duracell AA and AAA
Woah Woah Woah there, little buddy; you've wandered into Eneloop country…
You cant stop here … this is eneloop country!
Perfect timing for Sunday 2nd April, not that I religiously change it every year if it is still working.
Why not put cheapies in if you're going to chuck them annually? They definitely last 12 months and cost a fraction of Duracells.
Yes! However, as I said;
not that I religiously change it every year if it is still working.
These are actually $2 on clearance at my local target. Bought 10 of them. Unsure if statewide or countrywide (I'm in bris)
Also $2 at Target Elizabeth SA
I've always wondered how/why smoke alarms don't start using a more common rechargeable format (or maybe that I just hack one up :P). Say 3 LiFePO's or something.
Because they don't want smoke alarms to start a fire?
LiFePO's unlike Li-ion and Li-polymer do not start fires. you can even cut the battery in half and it wont start a fire
Heck they should use AAs or something. 9V needs to die in a fire.
AA batteries would probably drain too fast. Smoke alarm is a device which operates 24/7 non stop.
A lot of alarms have that mains power too. Could make ones with built in charger. 6-8x AAs would be a bit bulky though.
AA batteries have approx 5x the capacity of a 9V.
Obviously you need 6 of them for a fair comparison, but even say 2x AA would still be more energy total in a much cheaper and more common variety.
Confused. If they have 5 times more capacity where do you need 6. I'm sure there's a simple explanation!
@tightwad: just guessing but I think one is 9v the other one is 1.5v. Then you'd be looking at amperage as well. Again just guessing.
@tightwad: Oversimplification:
AA is 1.5V ~2500mAh.
6xAA in series is 9V ~2500mAh.
9V is 9V (obviously) ~500mAh. (In fact 9V "cell" is usually a battery with 6x AAAA cells in series.)So :
2xAA = ~7.5Ah of energy total
9V = ~4.5Ah of energy total
Are these that much better than the Varta that are $4.98 per pack of two at my local Bunnings?
Be careful if you buy from Coles I found that they have very old stock expire on 2015 or 2016Jan.
Good deal. A whopping 5c cheaper than Coles too at the moment. Good if you have a Bunnings nearby. :)
