      We've kept our minivan in the garage for the whole period of travel restrictions, used a smaller car for all shopping trips. Today I discovered that the battery has died completely. Should have disconnected it or recharge from time to time. Tried to resurrect it using a wall charger, but no luck - the charger just displays an error and that's it. Hopefully your battery is not as dead as ours.

      • Gracey on 16/05/2020 - 09:28

        @mangoed what sort of charger are you using? If you have jumper leads and another battery, try hooking it up for 5 minutes then try the charger again. If the voltage is too low on the battery the chargers can’t start

        • mangoed on 16/05/2020 - 14:01

          It's similar to charger advertised in this post - one end to wall outlet, the other end to car battery.

      Ctek used to be good but I've had 3 faulty ones now, so never again. They are notorious for their mode buttons failing (google it).

      I have my 4WD and camper on charge 24x7 when not in use and I've had Ctek and Bosch brand chargers fail. I'm on to Victron brand now.

      • Name on 16/05/2020 - 08:07

        Victron all the way. I've had a victron charge controller going for 6 years now without fail. Lugging it all over the country side.

    • ripprind on 16/05/2020 - 06:39

      on paper this one is much better:
      has screen
      charging faster than ctec
      also charges 6V batteries
      also charges "lithium" batteries

      on the other hand,
      doesn't have modular connection wire - probably an indication that its not meant to be installed for prolonged periods

      I would buy this one if I didn't already have ctec. I only wish this one would also show voltage on screen

    • haytona on 16/05/2020 - 07:48

      Ctek also comes with an eyelet connector which can be left connected to battery connections. This is really handy if your battery is under all sorts of plastic covers so you don't have to remove them each time. I use this every couple of weeks so our cars stop/start feature keeps working.

      No comparison. The SCA one is only 7 stage. This is 9 stage. Plus lower amps as has already been pointed out. If you want to compare, Repco sell a similar one

    Careful this charger will not properly charge a calcium battery.
    These are quite common in modern vehicles.
    Definitely check.
    Need one of these at a minimum if you have a Ca battery type;
    https://www.dicksmith.com.au/da/buy/certa-smart-battery-char…

    From a battery website;
    http://www.challengebatteries.com.au/battery-faq/
    What is a “Calcium” battery?

    A Calcium battery is a still a lead acid battery; they are usually sealed maintenance free. Calcium replaces antimony in the plates of the battery to give it some advantages including improved resistance to corrosion, no excessive gassing, less water usage and lower self discharge. Silver is another additive used by some manufacturers, the addition of silver enables the battery to be more resilient to high temperatures.

    Calcium batteries require a higher charge voltage than conventional batteries. If used in a deep cycle situation it is advisable to use a charger designed for calcium batteries or has a calcium charging mode to get the maximum life out of the battery.

    • spy on 16/05/2020 - 01:23

      So stick to CTEK?

    • pencilman on 16/05/2020 - 09:13

      How does one find out if a modern car (eg. Audi or VW) uses a calcium battery. Doesn't seem to come up on the battery specification?

      • ZachBlasphemy on 16/05/2020 - 09:36
        +2

        Probably best to physically check what's in the car.

    • John Dough on 16/05/2020 - 18:38

      I have two calcium batteries.
      I use this on rejuvenation mode every 6 months;
      https://www.ebay.com.au/itm/153310862990
      Also do a full low amp charge every 3 months.
      Batteries over 5 years old and are testing as very good health.
      Probably get 8+ years out of them, so a wise investment IMHO.
      Cheers.

      • edrift on 17/05/2020 - 08:26

        Out of curiosity what cars came with calcium batteries?

        I had never heard of this type before. I've only heard of lead acid, AGM and gel.
        Oh and lithium

        • John Dough on 17/05/2020 - 09:26

          Sorry I don't know which car manufacturers use this type of battery. It's best to open your car bonnet and google the battery model number.
          If you buy a new, sealed, lead acid battery, and don't choose the cheapest rubbish out there, I'd be willing to bet it's a Calcium variant, they are quite mainstream in all battery manufacturers (but can cost a bit more than regular batteries)

          Taking this into consideration, it probably depends more on why you are actually buying a battery charger in the first place.
          If it is because your battery is toast, alternator is on the way out and wont charge properly etc then it probably won't matter what you do, any charger will top up any battery and it's better than nothing to get you out of trouble.

          If you want to keep say a camping battery topped up between camping (and possible small solar feed while camping), anything is probably better than nothing, but a trickle charger or battery maintainer is probably best for that.

          If, like me, you simply want to keep your car batteries in top shape (I run a dashcam off mine too) then I prefer a charger that can provide proper charging voltage for my type of battery. Will it make ~$50 in difference between say this charger, or a more expensive one - I don't know the answer to that, but I can take some satisfaction in knowing that I at least am giving it the best chance. I guess I will know in a few more years if my batteries last >8 years (I think they will), I'd say I did something right.

          Everyone has a different end result they are seeking, a lot to consider along the way. Cheapest isn't always better, do your research or ask someone who is experienced to tailor a solution to your problem.
          Cheers.

      This does 14.6v max when charging 12v calcium batteries. Most likely the same top voltage that the other charger uses.

    Any recommendations for a non-smart charger to use in an electrolysis bath?

  • tetsuma on 16/05/2020 - 02:26

    My bike has an SAE connector hooked up to the battery. I can't see why this wouldn't be suitable for cutting and soldering in an SAE connector on the end of the charger. Am i missing something? Looks ideal otherwise (frankly overkill).

      (Motorbike?) is it a Lead-Acid battery? if yes then yes.

      • ZachBlasphemy on 16/05/2020 - 09:41

        The description does mention it can charge lithium but I can't trust it enough to connect to my bike. From other chargers I've seen they either do lithium or lead/gel/etc but not both.

    Anyone actually bought one of these previously and care to comment on its quality and features?

    I had a quick read of the manual and it seems to suggest that the car battery needs to be disconnected, before commencing charging. Is this correct, as I thought one of the benefits of trickle smart chargers was you didn’t have to disconnect the battery from the car.

    • ecdysis on 16/05/2020 - 12:46

    • John Dough on 17/05/2020 - 08:20
      +1

      Sometimes a manual will show two different procedures for connecting your charger, one for in car and one for out of car/aux battery e.g one you take camping.

      Most if not all chargers will charge a battery just fine in car, your car's electrical system is shut off from the battery when it's turned off.

      To be safe, you should not start the car with the charger connected and operating, it will probably just disrupt the stages of the smart charger, but better safe than sorry.

    My charger arrived this morning. Hooked it up to the car to charge now.

    First impressions:

    About 4 times bigger than a ctek charger I've used before but not as big and certainly much lighter than my repco linear charger.

    Cables feel super cheap quality. They are not the rubberised automotive style cables you would expect.

    The screen is extremely hard to read. In particular the indicator showing AGM, standard or gel battery types is about size 0.5 font. I have fairly good eyesight when wearing my contact lenses but I really struggled to read the display.

    The modes are actually more confusing than expected. It's just not intuitive. I'm a qualified engineer and I struggled to understand why there were so many permutations of charging settings.

    Now to the positives:

    1. It clearly shows you the measured capacity of the battery (mine was at 60%)
    2. It clearly shows you the charging current and charging voltage
    3. It's lightweight
    4. The LCD is backlit
    5. It seems to be 'smart'. You can see the auto mode select varying current and voltage depending on current battery status.

    Other thoughts:

    I'd like to understand why I would ever choose a specific charging current over auto mode. The manual doesnt explain this. If it has the smarts then why let a user force the wrong current levels into a battery?

    Why does it charge at only 2A instead of 6.5A in auto?

    When would I want to just recondition mode? Is this the same as maintenance mode?

    The manual is terrible. It doesn't explain much and relies on status/mode titles as the description

    • apu on 17/05/2020 - 10:51

      For the price, would you recommend it?

      • edrift on 17/05/2020 - 10:55

        Hell yeah. At this price point nothing comes close.

        A decent car battery costs $250+ so buying a $37 to maintain it is money well spent.

        • apu on 17/05/2020 - 11:49

          Thanks Ordered based on your comment. Yeah I recently changed the battery in one of my cars and it cost 260 bucks. Even it was showing some signs of discharge at only six months old because I haven’t driven it for the last few months because of WFH.

    Received mine on Saturday which I thought was amazing. And perfect timing. Car battery flat and couldn't jump start it with an old jump starter. NRMA guy came out and tested the battery and said it's not holding power. Told me to get a new battery. Took the battery out and ran the recondition setting for about a day, then auto on the next. Put it back in and started perfectly, turned off, started again. Left it two days and started ok again. Then used it on two UPS batteries that had failed - both UPS systems are back up and running. Excellent product for my needs!
