    Why the hell is it so big? I have an Autobahn one and it's about 20cm long, 5cm wide and 3cm high.

      It use traditional transformer and rectifier instead of switch mode power supply ( the one use in mobile charger and computer ) that why it is heavy and big .

          Come back in twenty years and see which one is still working

          • Lps on 12/08/2019 - 11:30

            @oznik: Quite right, who knows?

            • ozhunter68 on 12/08/2019 - 14:15

              @Lps: You can imagine which one would survive power spikes/short circuits/overloads/heavy loading in hot weather better/longer, one made with heavy step down tranformer with little electronic circuits and no transistors/chips, or newer type full of delicate electronics and chips?

              • Lps on 12/08/2019 - 20:51

                @ozhunter68: Possibly the switch mode one I’ve been using regularly for 10 years. Halfway there!

            • oznik on 12/08/2019 - 15:47

              @Lps: I know - the simple linear one

    • IVI on 12/08/2019 - 17:03

      Is it so big…? Or at the alligator clips just small..?

      Wait there's better still, if not the smallest available:

      • ~Au$ 16 [Shipped] for a kind of smart charger (Light weight, No xformer)

      Hunt for it on AliExpress (it's Not scarce)

  • placard on 12/08/2019 - 10:01

    Why would you buy this over a smaller one? The smaller ones are smart chargers too, so they won't overcharge? This one looks like it will just keep charging.

    • iShibby on 12/08/2019 - 10:03

      Price?

      Details say it stops once fully charged?

      • Tacooo on 12/08/2019 - 10:22

        I got mine for $70 from Autobahn without any discounts.

        • iShibby on 12/08/2019 - 10:33

          So double this price…

          • Tacooo on 12/08/2019 - 10:56

            @iShibby: Yeah without having to wait for the one time a year it was discounted.

      • Unity55 on 12/08/2019 - 12:30

        Ctek MXS 5.0 is around $55 when they on sale.

      Once the battery is full, the battery charger will automatically monitor the battery and top up the battery when required to ensure it is always ready for use. The battery charger can remain connected to the battery without risk of overcharging.

  • edrift on 12/08/2019 - 10:01

    Does this charge all types of car batteries or just older style lead acid ones?

    • Soapdroid on 12/08/2019 - 10:05

      I'd like to know if this will charge AGM batteries as well, I'm suspecting not.

    • Tacooo on 12/08/2019 - 10:24

      The case only states lead-acid so I don't think so.

    • SteveAndBelle on 12/08/2019 - 11:26
      +6

      I zoomed into the top of the box image and it states "Automotive Lead Acid Type: WET, AGM, GEL, VRLA & CALCIUM" so yeah, looks like it may do a few Lead Acid variants but of course it can't handle other chems.

      Great price for a big & dumb yet rock solid reliable transformer-based charger! Assuming the regulation/monitoring circuitry is of a reasonable quality a charger like this should last 20+ years as there isn't much in them to go wrong.

  • Tacooo on 12/08/2019 - 10:24

    Hey OP the product states lead-acid only. Might want to update the title/description to reflect that.

  • edrift on 12/08/2019 - 11:48

    Ordered one. Will return it if it's no good

  • ShipShapeRC on 12/08/2019 - 12:45

    3 times the charge rate of the $27 kmart one

    Hi All,

    For anybody wondering, this is a 'dumb' battery charger.

    They work by initially supplying a constant voltage and constant current to the battery until the upper charge voltage limit is reached, at which point the current drops due to battery saturation.

    These batteries chargers are notorious for overcharging batteries, but they are cheap and fairly reliable.

    I'd strongly recommend instead a three-stage (bulk, absorption and float) battery charger such as this one from Repco for an extra $8: https://www.repco.com.au/en/brands/repco/repco-switch-mode-b…

    Hope this helps.

    • edrift on 12/08/2019 - 13:03

      Will the linear charger damage my battery anymore than say if I didn't charge it at all?
      I only drive my car on weekends and even then it doesn't get long drives so I'm worried about the battery screwing up.

      • Bob81 on 12/08/2019 - 13:10

        Hi endrift,

        If you leave your linear battery charger attached to your car battery, it will damage the battery.

        Get a three stage battery charger and you can leave it attached to your car, as it will float charge your battery once it's fully charged.

        • edrift on 12/08/2019 - 13:27

          But it says it's automatic on the box?

          • Bob81 on 12/08/2019 - 14:07

            @edrift: 'Automatic' is just marketing. There's no indication of this charger, charging batteries in stages and if it had these features, it would advertise it.

          • teacherer on 12/08/2019 - 14:40

            @edrift: Once the battery is full, the battery charger will automatically monitor the battery and top up the battery when required to ensure it is always ready for use. The battery charger can remain connected to the battery without risk of overcharging.

      • dlovep on 12/08/2019 - 13:16

        I think you should look at the power bank jump starter

        • edrift on 12/08/2019 - 13:23
          +1

          No I don't need one of these. If I let my battery go that flat then it's probably be wrecked even more

          • ozhunter68 on 12/08/2019 - 14:22

            @edrift: ^^^Correct^^^

            I'm pretty sure you could just connect this charger to your battery for a couple of hours every week/fortnight/month depending on your milage and be alright. Just don't leave it charge all night too often unless needed.

            Alternatively, spend a bit more for a smart charger, connect and forget, just don't drive off before disconnecting first lol.

    For anyone wondering:

    I bought it and tried it out today on my AGM battery.
    It started charging at 5A according to the analogue gauge on the unit.
    After a few hours I checked on it and the needle was bouncing between 0-4A continuously. I guess this was a sign that it was done charging.
    A very crude way of stopping the charge but I think it would be effective.

    May consider returning this on the weekend of I find a better deal.
    Ebay cheapies are around this price and supposedly smart chargers… But I'm not sure if I trust the quality to leave it charging overnight.

    • errorius on 12/08/2019 - 19:45

      Bought one today, tried charging my AGM battery but even power led didn't light up. Guess I got a faulty unit. Will be getting replacement tomorrow.

  • stylsh on 13/08/2019 - 00:03

    These "dumb" chargers are also the ones you need to revive a completely dead battery that has been sitting in your "I'll get to it later" project car for the last 12 months. The smart ones will just error out.

  • iShibby on 13/08/2019 - 18:00

    Probably a silly question but can you jump start a car using this?

    • edrift on 13/08/2019 - 20:24
      +1

      No. You would have to use it to charge the battery first

    • Bob81 on 14/08/2019 - 14:32

      @iShibby: You'd want a portable battery jump-starter pack for that. Something like this: https://www.ozbargain.com.au/node/476260

      • iShibby on 14/08/2019 - 16:30

        Could you maybe charge it for a short while with this then start the car? Or would it take too long to get enough juice to start

        • edrift on 14/08/2019 - 19:10

          You could. Depends on how you define 'too long'.

          This is a 6A charger which is on the larger size for consumer car battery chargers

          • iShibby on 14/08/2019 - 19:21

            @edrift: Hour? Would have to try I guess. I bought one of these anyway just in case

            • edrift on 14/08/2019 - 19:43
              +1

              @iShibby: One hour wouldn't be long enough if it's so flat that you can't start the car. I would guess you'd need 10 hours at least.

              • iShibby on 14/08/2019 - 20:35

                @edrift: Thanks mate, might take this back as I really don’t have a need for it
