    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 .

    •  

      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)

  •  

    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.

  •  

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

    •  

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

    •  

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

      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.

  •  

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

  •  

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

    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.

      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.

      •  

        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.

        •  

          But it says it's automatic on the box?

          •  

            @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.

          •  

            @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.

        I think you should look at the power bank jump starter

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

          •  

            @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.

    •  

      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.

  •  

    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.

  •  

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