    I bought one of these a while ago when a Amazon one failed. This kmart one is legit works well, has been charging the small sized battery in my evo perfectly would definitely recommend considering the price, even if it wasn't on sale

      Good for 9 bucks, for 27 aldi has one that I think is 6 stage and 4A

    Only 2A current. Probably only good to trickle charge car battery.

    If I left my car light on, can it be use to jump start the car? BTW, low or no stock in a lot of places.

      I think you're after a jump starter.

        But if I use the Kmart one and charge the battery for 8 hours, the car will be able to start again, right?

          Yeah whats the use for this when you can jump start?

            @Circly: WFH these days, car hardly get used. Have my CTEK MXS5.0 plugged in to top up the battery essentially.

            @Circly: After you jump start, itll need to be run in for a long time to charge it. This will help instead.

      • htc on 10/07/2021 - 16:43

        Thanks, I was thinking about buying but you reminded me this is a slow charger not a jump starter for emergency.

        • martialmonk77 on 11/07/2021 - 10:07

          great question mate. I had similar experiences. Ended up having to use a second car with just the cables.

        • jimojr on 11/07/2021 - 10:18

          For jump starter you need one like this.

      • htc on 10/07/2021 - 16:44

        So in what cases will the 12V car battery charger be used?

        • adn on 10/07/2021 - 20:38
          +4

          For a car that isn't driven much or for long enough
          A car that has been put into storage but you don't want to disconnect the battery
          A car that has dashcam and gps tracker that doesn't get driven much.

    https://wagan.com/blogs/news/the-9-stages-of-battery-chargin…

    Difference between 3 stage and 6 stage and 9 stage in this article.

    Mainly: 3 stage has charge to 80, slow charge and then trickle charge at 95%.

    6 stage has evaluation and reconditioning cycles to de-sulfate batteries.

    9 stage has a recovery charge to charge deeply discharged batteries, and pulse mode to desulfate plates.

    • Russ on 12/07/2021 - 23:25

      to de-sulfate batteries

      Many chargers have claimed to de-sulfate batteries, but I've never heard of any reviews testing this functionality.

      There are plenty of people saying that de-sulfation is snake oil and doesn't work, has anyone here ever tried recovering a battery that wasn't used for six months or so, and did it work?

  • cloudy on 10/07/2021 - 18:16

    I don’t drive much, in an average week I would drive 2-3 times.
    Once a week is a 2x 30mij drive on freeway. The other 1-2 times we drive is only 2x10 min drive to shops.

    Should I be using one of these to charge the batteries since I’m not driving enough?

    • jjsnacks on 10/07/2021 - 18:22
      +1

      No, driving once a week is plenty enough to keep the battery charged

      • sintro on 11/07/2021 - 11:43

        Driving once a week for a short trip ain't gonna do it though.

    • knasty on 10/07/2021 - 19:09
      +2

      For $9 I would do it. Your car alternator will keep the battery sufficiently charged but likely not fully charged, and fully charging batteries prolongs their life.

    Takes 44 hours to charge a 70Ah empty car battery…
    A flat battery is considered to be 12.0V or lower.
    Fully charged is 12.6V or above.
    44 hours to go from 12.0V to 12.6V is crazy slow…

    • MikeKulls on 10/07/2021 - 22:26

      Fully flat is less than 12V, more like 10.

    • keegs on 10/07/2021 - 22:40
      +2

      10.5v is "flat" if you research elsewhere.

    • OnlyFans on 11/07/2021 - 09:07

      https://www.centurybatteries.com.au/technical-support/maximi…

      My comment was based off the information on this website…

      Would be good to know what they define as "empty".

    • Russ on 12/07/2021 - 23:21

      44 hours to go from 12.0V to 12.6V is crazy slow

      That's with a 70Ah battery, which is a big battery. The battery for a small car is typically 35-40Ah, average cars 50Ah. 70Ah would be for a large vehicle, or for vehicles with diesel engines (takes more power to start a diesel).

      This charger is more for maintaining the battery in a car (or golf cart etc) that is infrequently used. Let it run overnight, about once a month.

    I think I will stick with a jump starter if my battery is drained and driving the car for 5 minutes.
    This battery charger sounds a little more inconvenient to use.

    • tom1401 on 10/07/2021 - 23:47

      Lead Acids really, really don’t like being fully drained. However, best of luck if you want to keep jump starting and replacing your batteries constantly.

      • Aglet on 11/07/2021 - 02:44
        +1

        In fact it's beyond that - they are only happiest when fully charged. I had a Mazda MX-5 that was only driven occasionally and kept it on a charger at other times. When I sold it at 11 years old it was still on the original SLA battery.

    • keegs on 11/07/2021 - 08:52
      +1

      This is a misunderstanding of what it is; it's a trickle charger. You can leave the charger on the battery forever so that when you want to drive it's ready to go..

    • [Deactivated] on 11/07/2021 - 18:08

      Same here.
      I would rather avoid having my bonnet open under a carport for god knows how long when I can just jump start and go for a long drive. Car to car is no longer necessary either when you have portable power bank jump starters.

      • Gaz1 on 12/07/2021 - 14:29

        Main advantage I found with using the CTek trickle chargers is substantially longer battery life.
        Car batteries don't seem to like going flat then being jump started.
        I just replaced a battery that was 8 years old & on a Ctek & the Battery guy said it was extremely rare for a battery to last that long.

    • placard on 13/07/2021 - 12:38

      Driving for 5 minutes won't charge the battery properly, either will idling it for 15 minutes.

      These chargers top the battery to 100%, most alternators won't even do that, and battery life is extended when batteries get 100% top up.

      I drive reasonably so don't need mine connected all the time, but once a month I'll just connect it overnight to give it a good charge. Hardly an inconvenience.

  • Brodo Faggins on 11/07/2021 - 00:04

    @OP - How was your expectations/testing? Also would you know how long a charge can take?

    • ozhunter68 on 11/07/2021 - 07:04

      I imagine expectation was that it would work as decribed and has AU warranty from b & m local store.

      In description mentions 44 hrs to charge a 70 Ah from flat to full, so ajust up or down for yours.

      Considering the price of normally $27 or now $9/$12 C&C then it is great as a basic, casual but slow back up charger.
