    Is the ongoing OzB euphoria with Eneloops still justified?
    Pricewise, not stacking up against Japanese Ikea LADDAs.

    •  

      Good question, or blasphemy?

      Certainly according to Choice the Coles batteries were about as good as the pros and far cheaper but sadly stopped selling them. I got a bunch and they've been good although the pro's were probably better (but more than triple the price I paid generally) IMO.

      I was wondering this too - what makes these worth twice the price?

      I dont know why you got downvotes, but I would rather buy the Laddas if they are LSDs too. By the time I utlise the 500 cycles, I would have lost them anyway.

      •  

        they all age over time , and the age would probably debate the output. before 500 recharges …..

        •  

          I agree, I have some turnigy LSDs that I got over 7 or 8 years ago. I dont think they hold charge as well anymore and they have barely been thru 15 cycles.

      Depends what's important to you. The Eneloops (regular & pro) are potentially the most aesthetic, premium-looking battery on the market, you can't deny that.

          Yeah I lost the battery cover on my gameboy and mum won't buy me a new one.

      I can't figure out how to buy LADDAs because there isn't an ikea within 2000km of me.

        me too.

    •  

      Jugee's are worth it probably. Not quite as pretty aesthetically but a constant 1.5V for the life of the battery (vs 1.3-1.2V) is a win over the Eneloops or LADDAs.

      •  

        Where do you buy these?
        I can only see 4 packs including charger. I already have a charger… Unless LiPo needs a different type.

        I'm interested if the voltage is true, as I think the voltage drop gives me low battery warning too early on some of my devices.

        •  

          Amazon, or Aliexpress. I chose Amazon, $38/4pk with prime vs the same price with slow shipping from Aliexpress.

          The Aliexpress ads seem to indicate their charger is required and isn't compatible with other rechargeable batteries, though I'm honestly unsure if this is just marketing fluff. At least ones included and (appears to be) USB-C?

          Compared to Eneloops or LADDAs they're certainly pricey, but if you're using devices that are voltage sensitive (modded gameboys, VR controllers are prone to this) they might just be worth it.

      Well for something dual purpose, I recently bought an 800 lumen 'worklight' from Bunnings. It comes with two included 18650 batteries but optionally powered by 4 AA.

      Take the batteries out when charged to plug into your other appliance(s). :)

      If you can handle slow charging over microusb, I couldn't find it on their website but 25 bucks or so I think.

    Do those fast charging eneloop chargers reduce the lifespan of the batteries like fast charging lithium does?

    •  

      Depends on how fast you mean. The ideal duration of charging for NiMh batteries is 2-3 hours. Faster damages the batteries from heat, and slower means the -dV/dT effect is very difficult to detect, so you run the risk of overcharging your batteries.

      Most chargers that are sold with eneloop batteries are in fact timer chargers (10-hour or 14-hour charge) - the worst type of charger possible. There are some good chargers made by Panasonic, but they're uncommon.

      •  

        I'm considering this
        https://www.camerahouse.com.au/eneloop-ncmqr06-fast-battery-...
        Seems like a decent price but if it's just a battery killing machine I'll pass.

        • +4 votes

          That must be a new model, I can't find any specs on it. The label says 1.5 hours charge with two AA batteries, so assuming it's like the older Panasonic smart chargers, the charging current and time will depend on how many batteries you are charging. Judging from the performance of previous Panasonic chargers, it looks like it will charge four batteries in about 3 hours, and that's good. But when charging two batteries it's a bit too fast, and if you were to insert only one battery, way too fast, likely less than one hour.

          It's also no bargain at that price ($42). Do you need a charger urgently?

          I recommend you buy the batteries from the above deal, or get some LADDA 2450mAh batteries from Ikea, and buy a better charger.

          For a simple low-cost charger, the Liitokala Lii-202 is good, but it doesn't have a mains power supply, you need to plug its USB plug into a phone charger or a PC. Currently about 12-13AUD if you purchase through Paypal from Fasttech (a Chinese marketplace), delivery will take 3-4 weeks typically: https://www.fasttech.com/products/0/10018115/5616100-authent...

          The Lii-202 only charges two batteries at a time. If you want to charge four batteries at a time, don't buy the Lii-402, the 4-battery version, as it can only charge four batteries at 500mA each - too slow. Buy two Lii-202 units instead.

          Also, Fasttech are having a 10%-off sale in a few days, see this deal, and read my comment in that deal: https://www.ozbargain.com.au/node/642641

          If you want a better charger, the Liitokala Lii-500 or Lii-500S or Lii-600 are excellent chargers, and pop up here on OzBargain a couple of times a year. Have a look through some of those deals. However they only come with US, UK or EU mains plugs, so you'll need a mains plug adapter. Be careful too, many sellers sell them without any mains adapter.

            @Russ: I already got the "smart" quick charger and i really shouldn't have. I feel really ashamed to admit it for some reason but i might as well share my experience so it might help someone.

            First of all, as I already said earlier, i can't get LADDAs, IKEA doesn't seem to deliver them and i don't live in a capital city.

            As for the BQ-CC55, My main problem with it is the thing will try to charge already charged batteries every time, and for a long time.
            I let it try and it went for like 20 minutes. I thought maybe the charger discharges the batteries by a ridiculous degree if you leave them in. So i pulled 2 out, left them overnight and put them all back in and no, if recognised all 4 batteries at the same level of charge and tried to charge them all again as if they were 80% full. (It starts yellow then goes green after 20-30 seconds).

            So yeah i don't trust this "smart" charger at all and that's not even getting to the heat issues. 2 batteries do indeed get absurdly hot, but 4 batteries get hot enough to almost be too hot to hold my hand on.
            Maybe the charger will be good if you unplug your batteries and put them away every time. Looking around that does seem to be best practice so I dunno, I think this whole thing's disillusioned me on eneloops. I just wanted something for my xbox controller and have had 2 of the lithium battery packs die on me and now i have to get battery cases or something. It's just all so inconvenient compared to those things.

              will try to charge already charged batteries every time, and for a long time. I let it try and it went for like 20 minutes.

              That's normal, all chargers do that. A smart charger can't tell if a battery is fully charged until it sees the -dV/dT effect, and that's an effect you only see when the battery is being charged. I don't know exactly how the -dV/dT effect is caused, but battery temperature climbs at the same time as the -dV/dT effect, so I suspect the warming of the battery may be required. I recently did the same test with my Lii-500 and some AA batteries, and it stopped after 21 minutes. As long as the batteries don't get hot while the charger is charging them, it doesn't harm the batteries.

              2 batteries do indeed get absurdly hot

              That's not good.

              but 4 batteries get hot enough to almost be too hot to hold my hand on.

              That's maybe okay. Batteries seem to survive if they get no hotter than 50 degrees C. For most people, 45-50 degrees is "I can form a fist around the battery, and it's uncomfortably hot". Above 50 degrees, most people have an automatic reaction that makes them drop the battery. 55 degrees is the lower limit at which first-degree burns happen.

              It would also be good to do a test, for when you have only two batteries you want to charge, to insert the two flat batteries and two fully-charged batteries. Hopefully the two flat batteries will only get as hot as when charging four flat batteries, not as hot as when charging two batteries by themselves.

              When comparing chargers, this website usually has excellent reviews, and includes temperature measurements and a thermal camera photograph of the charger. Here's the page for the Lii-202, says the maximum temperature for NiMh batteries reached about 32 degrees (see the temperature curve on the graphs): https://lygte-info.dk/review/Review/Charger/LiitoKala/Lii-20...

              Note that the temperature at the start of the temperature curves is around 25-30 degrees C, I think it's fair to assume that's the air temperature where the batteries are being tested. If you do the same test when the ambient temperature is 40 degrees, expect to see higher temperatures.

                That's reassuring at least
                I think it is slowing down the charge when it's super hot because I can hear the electronics for some reason and it goes from ticking quickly like a clock to clicking once every 3 or 4 seconds when it's hot, I thought it might have been slowing down because it was almost done charging but it might be sensing the temperature somehow

              @Lief1250:

              As for the BQ-CC55

              I just re-read your comment - is it a BQ-C55? I was looking for "NCMQR06" when I searched, I assumed Camera warehouse had just recycled the webpage of the older BQ-CC55, and only updated the part number in the header. The BQ-CC55 is an older charger, but it has "Panasonic BQ-CC55" stenciled on the front, and that's missing in the pictures on Camera House's webpage.

              If it is the BQ-CC55, then here is a detailed review of it: https://lygte-info.dk/review/Review%20Charger%20Panasonic%20...
              That would also explain the "ticking" you heard, it pulses power once a second during the main charging cycle, and drops to a slower speed during the "top-off charge" according to the review. The thermal photo shows the batteries reaching 45 degrees when charging 4 batteries, which is toasty hot, but survivable for the batteries. The plastic casing of the charger reaches 57 degrees though, that's dangerously hot.

              In the review, they do re-insert a fully-charged battery, and the BQ-CC55 stopped the main charging after 10 minutes, but kept the top-up charge running for another hour. So maybe that's what you saw? Rather confusing behaviour if so, it would make you think it is not correctly detecting a full battery. Or do the lights correctly indicate charging complete, while the top-up charge is proceeding?

              I suggest you buy a Lii-202 and I think you'll like its performance a lot more, assuming you already have a battery charger that can output 2 Amps, or a desktop PC to connect it too (Laptops usually can't provide that much current).

    Twice the price of ladda , no thanks

    If I didn't already have 16 of these and 16 of the normal Eneloops, I'd bite.

    All I know is that I started using them in 2013 and they're still lasting freaking forever in devices that I use daily.
