    Thanks OP! Have been looking for one.

    Charging current of 1 amp is going to take a very long time to charge a 120 amp hour battery.

    • rustyaxe on 09/07/2020 - 15:35

      How long roughly? I don't know anything about this type of stuff. Thanks

      • OnTheMark on 09/07/2020 - 16:12

        From flat, at least 120 hours - i.e. 5 days.

        • fatty on 09/07/2020 - 21:21

          You should not be running lead acid batteries below 50% capacity (12.0V) to avoid permanent damage, therefore a 120Ah battery discharged to acceptable levels should take 60 hours to charge at 1amp.

        • rustyaxe on 14/07/2020 - 08:14

          I know it's a bit late but thanks for the answer OTM

    • PerthectDeal on 09/07/2020 - 15:41

      Yep certainly not a quick charge but great if you dont use your car much and can top it up every now and then.

    • jaymzrsa on 09/07/2020 - 16:10

      There is a reason these are generally termed "trickle chargers" :-p

  • Maki on 09/07/2020 - 15:29

    Bought one, not sure why, but thanks OP

    • FishVille on 09/07/2020 - 16:03

      i had the same problem…

      • iDroid on 09/07/2020 - 20:12

        I think it's airborne as I caught it too.

      • ialam99 on 10/07/2020 - 07:57

        I'm thinking of buying one as well but not sure exactly what this does. Are these used for when we get a flat battery?

        • edrift on 10/07/2020 - 08:07
          +2

          No. These are used to prevent a flat battery

  • PerthectDeal on 09/07/2020 - 15:49

    Great price thanks Op!

    Looking at buying one of these as I dont use my car much these days.
    Good reviews as well. Bargain $20 with free delivery.

  • tagrobert on 09/07/2020 - 15:49

    1A is only good for trickle charging for cars in storage. My 6A(max) charger takes about half a day to charge my car battery from an almost flat state.

  • edrift on 09/07/2020 - 16:37
    +7

    If you are not specifically looking for a trickle charger then don't buy this.

    If you think you want a car battery charger in case you get a flat, then this charger is NOT for you.

    Most car batteries will be in excess of 100Ah rated, which means it'll take 100 hours for this charger to charge a completely flat battery.
    In reality a battery that is completely flat will be destroyed anyway, so hopefully if you get a flat it'll still have at least 40% juice left. But even so, you are looking at about 24 hours charge time before you can even start the car once, or about 3-5 days to fully charge the battery.

    This charger is more useful for people who drive their car once a week/fortnight/month and want to leave it on a trickle charge when they are not driving.
    Watching grass grow is faster than this charging your car battery.

  • CereaL on 09/07/2020 - 17:08

    Anyone know if this would work with scooter/motorcycle batteries?

    Seeing we're in lockdown .. could be a good way to make sure the battery survives .. lol

    • Solrak on 09/07/2020 - 17:29
      +4

      Yes this would be fine for motorcycle batteries

      • CereaL on 09/07/2020 - 17:32

        Thanks

    • edrift on 09/07/2020 - 20:02

      Yes. This would actually be ok for scooter and motorcycle batteries because they are much smaller (10Ah or less) and like to be charged slowly (2A or less).

  • AMLagonda on 09/07/2020 - 17:58

    I cant really say this is a bargain for a 1amp charger, even a alternator is 75 to 120 amps…

    • Nivlac on 09/07/2020 - 18:00
      +3

      This is a trickle charger. For long term idling battery storage. Nonsense to compare it with a vehicle's running alternator really.

      • AMLagonda on 09/07/2020 - 18:01

        Can buy a 2amp charger for the same price on ebay.

        • PerthectDeal on 09/07/2020 - 18:39

          Got a link, I can only see Australian delivered 2A ones for $24 and these are only up to 20AH

        • [Deactivated] on 09/07/2020 - 19:20

          Can get a 10000000amp charger on eBay for $20 too.

  • beanlanda on 09/07/2020 - 18:05

    Thanks OP needed a 6v one for some sealed lead acid lantern batteries for the day we can go camping again!

  • whoopdeedoo on 09/07/2020 - 19:09

    for car storage, would it be better to just unhook the negative terminal? not fussed about saving radio stations.

    • edrift on 09/07/2020 - 20:03

      Yes

  • plague69 on 09/07/2020 - 19:35

    No switch and can charge lead acid, AGM and Gel? Fishy…

  • ganymede on 09/07/2020 - 19:56

    This vs CTEK?

    • edrift on 09/07/2020 - 20:04

      If it's a ctek 1A charger then get this instead.

      • iDroid on 09/07/2020 - 20:14

        Why? I have a 0.85amp ctek and it's fantastic for keeping batteries and restoring dead/poor performing batteries.

        Is this one even better?

        I also have large 25amp projecta chargers - but that's for different jobs than the ctek.

        • imnotarobot on 09/07/2020 - 20:51

          I have three ctek trickle chargers and one projecta and bought this too. Why? Twenty bucks. Cteks are at least three times this price.
          My projecta charger has been working pretty much non stop for 6 years. I’ll gamble with this for the price.

        • edrift on 09/07/2020 - 22:47
          +1

          Price. A ctek costs much more for very little benefit.

  • Lancerx on 09/07/2020 - 20:36

    Can't use for jump starting I guess?

    • iDroid on 09/07/2020 - 20:44

      Correct. No jump start with this.

  • ASA on 10/07/2020 - 08:39

    Thanks op. Just nabbed one too. I have a trickle charger for my motorbike but the car has been flat on me a couple times lately (new battery too) since it rarely gets a run.

  • coolsteps on 10/07/2020 - 12:07

    sold out i guess i saved myself $20

    1A is Useless. You need at least 5A. Repco has 6A charger which is clearance. Check this

    • dmbminaret on 14/07/2020 - 18:28

      This is untrue. If you want to winterize your jetski and not have the battery go flat, this is the thing you need. Any more than 2A and you will cause damage.

      • n2h on 14/07/2020 - 20:40

        Smart chargers know when it should stop. Dont worry about this. 1A takes forever to charge car battery. 6A 7A even takes 8h 9h to charge a car battery from flat to full. So how long do you think it would take for a 1A charger to do this job?

        • dmbminaret on 14/07/2020 - 21:07

          It doesn't matter if you're not charging a flat battery but maintaining a charged battery.
