      Ended up paying $4.20, the agent didn't price match to Amazon, as amazon is not in their policy due to membership rules

      Bunnings have the same price - so price matched it to bunnings and used the perks voucher - https://www.bunnings.com.au/energizer-recharge-extreme-1-2v-…

    • db2k on 10/10/2025 - 12:11

      Wait, isn't it policy that JB will not price match Prime, as it's a membership subscription - just like they don't price match Costco…

        • Ankit4632 on 10/10/2025 - 13:42

          That's good ! I tried matching a monitor on amazon with Office works and they denied saying Amazon comes with subscriptions and hence can not on prime deals. Talked with 5-6 representative and everyone said same.

      NiMH charger of any reputable brand.

    • NimbusTLD on 10/10/2025 - 12:05

      This is a good option: https://www.amazon.com.au/gp/product/B0CBX87FZT/ref=ox_sc_sa…

      • Russ on 10/10/2025 - 13:16

        The specifications of that charger are hiding something. It says "1000mA charging" and "5-hour charge time". Both of these can't be true, the largest AA batteries are ~2500mAh which will charge in 3 hours or less at 1000mA. So most likely they're lying about the 1000mA charge current, or there will be some other unlisted rule like "1000mA when charging 1 or 2 batteries".

        • Genepi on 10/10/2025 - 21:55

          I reckon these charger list the max. Perhaps they tend to taper the charging rate towards the end of the battery?

      • Russ on 10/10/2025 - 13:39

        Liitokala
        Nitecore
        Xtar

        Each of those brands make some good chargers, but plenty of bad chargers too.

        If you want your batteries to last, you want a full charge to take 3 hours or less. So for 2300mAh batteries like the ones in this deal, that rules out chargers that can't provide 1000mA per battery.

        It's often hard to find such information, for example the Liitokala M4S says it has charging currents up to 3000mA, but when you get it, you find it can only do 3000mA when charging a single lithium-ion battery. For NiMh batteries it'll do a maximum of 1000mA, and if you're charging 3 or 4 batteries that drops to a maximum charge current of 500mA - too low for AA batteries.

        The only Liitokala chargers I know of that can charge 4xAA NiMh batteries at 1000mA are the Lii-500, Lii-500S and Lii-600.

          If you want your batteries to last, you want a full charge to take 3 hours or less…

          why is that?

          • Russ on 10/10/2025 - 14:40
            +4

            @cloudy: The whole advantage of a smart charger is that it stops charging each battery when the battery reaches "full". There are two ways the charger can detect when a battery reaches "full":

            • Monitor the battery temperature precisely, looking for a temperature rise above a certain threshold
            • Monitor the battery voltage very precisely, and detect a very small "dip" in that voltage which occurs as the battery reaches full charge.

            Monitoring temperature is problematic, because it can be affected by so many other things, like someone turning on the ceiling fan on a hot day. Or the sun coming out from behind a cloud and shining on the battery. Some chargers have temperature detection, but only as a backup method.

            The main method used is to look for that voltage dip, and it's called "-dV/dT detection". But the dip is only easy to detect if a full charge takes two hours or less. It's still detectable if the charge takes 3 hours, but longer than 3 hours is into "maybe not detected" territory.

            There's a technical version of that explanation here, where they say

            At a C rate of 0.1C to 0.3C, the voltage and temperature profiles do not exhibit defined characteristics to trigger full-charge detection, and the charger must depend on a timer.

            Charging at 0.3C gives a charge time of just over 3 hours. For a 2400mAh battery, 0.3C means charging at (2400mAh x 0.3) = 800mA, so you need your charger to exceed 800mA charge current - hence my recommendation of 1000mA.

            And also, the "dip" in voltage was more easily detected with NiCad batteries, which were superseded by NiMh batteries. NiMh batteries have a smaller "dip", so the detection circuit has been adjusted to look for "voltage has stopped rising" rather than "voltage is going down". It's still generally referred to as "-dV/dT detection" though.

    • kotobuki on 10/10/2025 - 16:28

      This charger seems decent. The last time it was posted here ($1 cheaper then), it got 55 upvotes.

      EDIT: I take that back. This is timer-based. Not the best it seems.

  • noshopping on 10/10/2025 - 11:56

    Used these a few years and and they don't hold charge when left lying around. Has anything changed in the last 2 years, has it improved?

    • NimbusTLD on 10/10/2025 - 12:05

      I agree, I bought some a few years ago and don't seem to be as good as my Eneloops

    • Elyxar on 10/10/2025 - 13:17

      "Each AA battery can be charged hundreds of times, with a charge lasting up to 12 months in storage". Doesn't seem to claim they are Low Self Discharge like Eneloops. Though the whole listing is suspect because it has the origin as USA and alkaline as the type.

      • Russ on 10/10/2025 - 13:50

        Doesn't seem to claim they are Low Self Discharge like Eneloops.

        They're very vague about these batteries, to the point of not having a datasheet available on data.energizer.com.

        If Energizer could make the same claims as eneloop pros do, "85% power remaining after 1 year in storage", they absolutely would put that on the packaging.

        That said, if you use batteries in a way that they need recharging every month or two anyway, Energizers are probably perfectly good.

    • PCHammond on 10/10/2025 - 13:21

      Yep, unless they have changed, Energizer rechargables are a steaming pile of crap

      I'll stick to Eneloop/Ladda and Amazon Basic

    • dufflover on 10/10/2025 - 17:22

      Same situation, had a set that looked exactly like these still. They did not behave like low-self discharge batteries at all, and in the end also stopped holding much charge a few years later. A few old LADDAS, Eneloops and even a set of Aldi ones I've still got hold more charge.

  • Kazusa on 10/10/2025 - 12:04

    I have these batteries, and they are not low self-discharge (LSD). I recommend Eneloop or Ladda LSD's over these.

  • MeatyMeatballs on 11/10/2025 - 13:00

    Can you charge these Energizer batteries with an Eneloop charger?

    • Russ on 12/10/2025 - 04:31
      +1

      with an Eneloop charger?

      I'm assuming you mean the Panasonic charger that came with some eneloop batteries.

      Yes, with conditions. If your Panasonic charger is the "smart & quick" one, then it'll treat the Energizer batteries well if you only charge one or two batteries at a time. The smart & quick charger was designed for charging four 2000mAh batteries at the same time, if you try to charge four 2300mAh batteries you'll exceed the three-hour charging limit (see my comment above for details). But it's okay when charging one or two 2300mAh batteries at the same time (i.e. leaving two of the battery slots empty). When only charging one or two batteries the charge current increases, and the batteries will charge in about two hours.

      If you have the Panasonic "10 hour" or "overnight" charger, those are terrible and will damage every battery put into the charger, so retire it and get a better charger.
