1.5 Volt alkaline batteries to power your life

According to their website, they are guaranteed to last up to 10 years in 'ambient' storage.

EDIT: Someone just pointed out there is a twin pack (40 pieces) for $9 @ catch for those who have membership there - https://www.catch.com.au/product/2-x-duracell-coppertop-aaa-…

For me shipping kills it though.

    How many of these are required to power a Tesla down the quarter mile?

    Asking for a mate.

      Not sure, but one pack should power your TV remote until about the year 2100.

    • +1

      450V / 1.5V (per battery) = 300 batteries
      300 / 20 (per box) = 15 boxes

      Depends on the model and how fast you want to go ;)

      The Model 3 uses about 1,000 Wh to do a fast quarter mile run. (The higher power versions use more power for a shorter time, so use a similar number of total Wh compared to the lower power versions)

      Duracell CopperTop AAA = 1150 mAh = ~1.6 Wh

      So around 625 batteries for 1000 Wh.

      First problem we run into is battery output. We need at least 208 kW for the lowest power Model 3. At 355V, that's 586 A.

      Duracell helpfully publishes the tech specs for the batteries, so we can check out how much power that can output.

      We see that while we can pull 1W from each battery, we get about half the nominal capacity vs only pulling 0.25W. Since we are just doing a quarter mile run, we will be output limited, not overall capacity limited, so we can bump that up a bit and draw 1.2W.

      First, we need enough batteries in series for 355V. The AAA cell voltage drops rapidly under load, but we reasonable get 1.2V for our run.

      So we need 296 batteries in series. That pack only supplies 1A, so we need 586 packs in parallel to reach 586A.

      173,456 batteries. There will be various efficiency losses to account for so we can round that up to at least 200,000 batteries.

      That's 2.6 tons of batteries. Over 3 tons by the time we wire them together.

      So at least $90,000 worth of batteries at the price in this deal. Double these results for the high performance Model 3.

      If it doesn't catch fire in protest, the battery pack has enough spare capacity to let us do a couple of quarter mile runs before the voltage drop is too much.

      All in all, not very economical.

      Interestingly though the battery pack is about 230 kWh nominal capacity. At an efficient cruise speed (conveniently ignoring how that is possible with 2.6+ tons of battery on board) our battery pack gives a range of 1500 km.

        Thanks very informative :)

        Ps. What else do you do in your spare time ?

    Great price but I've had too many experiences with Duracell batteries leaking in devices, making a mess in the process. Will never buy again.

    • +1

      This. Duracell leak like crazy. Are they made out of paper?

    • +2

      Same. Had too many Duraleaks over the years, avoiding no matter the bargain.

    • +2

      Yeah I’ll add to the list, although it was Procell by Duracell.

      Leaked in my Wii Remotes, Garmin eTrex GPS, and sensor lights.

      Won’t touch the brand now. Varta batteries in the same devices have had no issues.

  • +9

    in my experience the duracells always leak

  • +4

    I also never buy Duracells any more. Too many ruined remote controls.
    They even leak in the pack before I use them.

    • +1

      Why would you use duracell on a remote, just buy some cheap ass no name battery.

  • +3

    The leaking only happens when you leave it in a remote and it has no charge left for a long time. Notoriously occurs with Wii motes, so for devices like that use rechargeables. Improper storage can cause batteries with lower charge to drain the batteries with higher charge, eventually causing the battery to go flat and leak. Ensure the batteries are not contacting each other on the terminals while in storage.

    • +1

      Whilst this is good advice, I have never had this happen with Energizers for example.
      I store in the original pacakaging with no terminal contact.

      • hmm that's odd. I don't think they ever leaked for me while kept properly stored. I've had every type of battery leak, because it's a safety mechanism built into every alkaline battery to prevent explosion in the event of losing charge for a long time.

        • Problem is also in the knockoffs around. I have bought before off ebay years ago and had non-genuines delivered. I learnt my lesson and keep away from Duracells.

          • @wetwork: oh yeah, that could be an issue. Ebay has a few shifty sellers sometimes

    • +2

      Good advice with the Wii remotes. I learned my lesson the hard way

    • +1

      Duracell are notorious for it. You only have to read the comments of others as well. Yes, it might be from leaving for too long in devices but Duracells seem to leak a lot easier/quicker than other brands of batteries. I use Energiser or Varta batteries and I don't use them any differently than I used to use Duracells but I hardly ever end up with leaking batteries since I stopped using Duracells….. and they weren't bought on eBay. Used to buy Duracells when they were 1/2 price special at Coles - but wouldn't buy them now if they were 80% off. Not worth the trouble. YMMV but that's not my experience.

      • Duracell AAA and AA are half price at Coles now. Good luck to anyone who wants to buy them. I certainly won't.

        • Energizer AAA and AA half price and woollies now for same exact price (but twice this price). We are all doomed.

    DuraLeak.

    Ahh i remember buying a pack for a ranga at work. It was her going away gift.

  • +1

    Camel Camel Camel shows its the lowest price its recorded. Not too bad pricing.

  • Do not buy Duracell. They are junk now.

  • +1

    Thanks, grabbed some for rainy days. Always seem to not have them when I need them.

  • +7
    • Damn I saw that price of $9, but didn't realise it was for a twin pack… Although shipping really kills it, maybe for members it's ok.

    • Real deal is always in the comment :)

    • This is fine if you have OnePass for Free Shipping. $10.95 shipping for me. I have prime, so the Prime purchase would be better for some. was better before it expired.

  • Thanks good find OP bought

  • Leak leak leaked

  • +1

    Thanks for the Catch link. Bought the 2x 20 pack and free shipping with OnePass.

    • Same $9 for 40 batteries delivered.

    I buy either the Aldi brand or Varta from Bunnings, they seem to be best bang for buck and they don't leak like Duracell.
    Anyone tried the Amazon Basics batteries? Are they any good or rubbish?

    https://www.amazon.com.au/Amazon-Basics-High-Performance-Alk…

    Sameish price as Varta

    • IME Amazon Basics aren't very good

      • Worse than Varta/Aldi? Any other cheapies you know of that are decent for kids toys and general low-medium draw gadgets?

    • +2

      I’ve been using the Amazon Basics batteries for the past year in low-medium drain devices (remotes, Bluetooth thermometers/hygrometers etc), they’re good. Have not tried them in high drain devices.

  • +1

    Went up to $14.84 as I was checking out

    • Dodged a leaky bullet.

    Received today a 3 pack iPhone charger cables instead of the Duracell Coppertop AAA Batteries, contacted CS and they are sending out a replacement set of AAA Batteries.
    Pity I don't own an iphone as I now am a proud owner of a 3 pack iPhone charger cables.

    • +1

      haha, maybe it was a scam and we'll get a bunch of old iPhone port cables

  • wrong deal, sorry
