This popular smart charger is under $100 once again. Highly recommend them!

There is also 30% off the XS0.8 for $69 and MXS7 for $199 but I think the MXS5 is the best value.

Description from website:

CTEK MXS 5.0 - Automatic charger for car batteries
The MXS 5.0 is an advanced battery charger with a microprocessor giving unrivalled performance for charging lead acid car batteries from 1.2Ah to 110Ah. The MXS 5.0 comes with built in automatic temperature compensation ensuring the best charging performance of your car battery, even in the extreme weather conditions Australia throws at it.

The MXS 5.0 has some premium features including a battery diagnosis faction to detect whether your battery can actually receive and retain a charge. A patented function for automatic desulphation, An AGM option which can maximise life and performance of most Stop Start car batteries. Recondition mode for reconditioning and detoxing deeply discharged batteries for greater longevity. Like most CTEK battery chargers, The MXS 5.0 uses the patented float/pulse mode, which is the most efficient maintenance mode especially when a battery is connected up for longer periods including trickle charging your classic/weekend car. CTEK offers battery chargers for car batteries, boat batteries and motorcycle batteries for professionals and consumers.

With the latest advancements in intelligent battery charging technology, CTEK are committed to maximizing battery performance with every product they offer. Constantly pushing the boundaries of research and development, CTEK have soared leaps and bounds above the competition because they constantly innovate, improve, and refine to your needs and battery charging applications. A 12 volt battery charger is an absolute must-have for those storing project cars which only see the road or track once in a blue moon, since batteries naturally discharge over time when left to sit without a charge applied to them, your battery's health is severely compromised if its only given time to charge every so often.

CTEK battery chargers great for restoring charge to totally flat batteries when they would otherwise end up in the tip which means they're friendly to your budget and for the planet. A CTEK car battery charger is also great for maintaining battery charge to occasional vehicles such as project cars, weekend cars, boats, jet-skis, RVs or anything you can think of so you can be sure your car, bike or boat will fire into life at the drop of a hat.

    I'll keep my eye out for specials on this, just added my first LiFePO4 to my array off batteries, this charger looks the goods.
    - edfoo on 20/04/2023 - 11:06
      
      Yes the max 22Amp charge can top up the lithium battery fast. 5Amp is considered too low for batteries over 100Ah capacity.
      - Malik Nasser on 20/04/2023 - 13:53
        
        @edfoo: The amp rating just affects the charging speed. 5A for a 100Ah battery is fine, as long as you dont need it for a while. If the 100Ah battery is completely flat (0% charge; 100% depth of discharge), it will take over 20 hours to charge.
        For AGM the standard charge rate is 0.1C, so for a 100Ah battery the standard charge current is 10A.

        edfoo on 20/04/2023 - 18:15
        
        @Malik Nasser: Yes, it still works but just very slow. And lithium battery prefers higher charge rate than AGM battery if I am not wrong.

        edfoo on 21/04/2023 - 09:17
        
        @G-rig: Not all lithium batteries are considered high-end if you haven't already noted a number of OzBargain deals posted on cheap brands such as VoltX. You can buy a VoltX 100Ah lithium battery for under $400 these days, so I doubt these people want to spend too much on a battery charger.

Good charger but not good for vehicles with relatively high current draws at the float stage of the cycle.
Lost a couple of AGMs before I released it was a function of the charger.
- Sheng on 19/04/2023 - 23:10
  
  I was going to get one for my AGM but might not now. What exactly ruined the battery?
  - 1tightwad on 19/04/2023 - 23:15
    
    The charger has a "safety" built in that cuts out if it detects too much current draw at the float stage. The charger didn't kill the battery directly, it being left with the cutout tripped for a few weeks did.
    I bought a Noco Genius 2-3 years ago and it's been fine since.

  Why does your car have a high current draw when off? Ive been using this charger on my AGM battery for over 2 years as a trickle charger with no issue

      My car had a high current draw when a module had failed which was keeping the car "awake". If your car does it normally then best option would be to just keep the battery disconnected rather than using trickle chargers.
  - garage sale on 20/04/2023 - 07:51
    
    common with many chargers they get to a certain voltage and current draw drops then go into trickle and assume battery charged and hold at trickle ……disconnect and reconnect and they go through their cycle again … could be fixed in software but there is a risk if faulty battery that it keeps pushing current to get to charge voltage which never occurs and battery heats up ……

    It doesn’t get that cold in Australia. But if you are storing it for winter, remove the battery from the bike and bring it inside.
    - whitelie on 20/04/2023 - 07:03
      
      Why not just plug it in to the charger on the bike? As you say, it doesn't get that cold, especially if it's in an enclosed garage.
      - ATangk on 20/04/2023 - 09:14
        
        @whitelie: If you don’t disconnect the leads there is still parasitic load on the battery.
        
        Bringing it inside is just easier I guess.
        
        whitelie on 20/04/2023 - 09:21
        
        @ATangk: The charger is designed to float the voltage so the parasitic loss isn't an issue.
        
        Not sure it's easier… I had the lead with quick release fitting and the eyelets permanently connected to my battery so it was a very quick plug in/out process when I wanted to charge it. Doesn't get easier than that unless there's no power point near your car/bike.

  I leave my bike plugged into a projecta charger from bunnings. I got sick of roll starting because I use it intermittently. I think it's 0.8 amp. Seems to do the job and was about $60 from memory. A good feature was it comes with a plug you can permanently mount on your battery. I wired it into the rear compartment and whenever I drive in I plug it in.

  They are fundamentally different devices. Trickle charger has a transformer inside, jumper starter has a battery inside.
  
  There is no economic benefit to manufacture a 2-in-1 one device that does both things.
  
  If you want to trickle charge "off grid", you will need a portable power station or power generator, both are large, heavy, and expensive.

Better off spending an extra $19 for a Gooloo S10 shipped from Amazon AU. The Gooloo is twice as fast @ 10 amps, supports Lithium and has a 12V power supply mode (for powering 12V appliances such as a fridge or pump, or for running you cars electrics off the wall)

    It’s a smart charger, not a dumb charger. It will only charge at an amperage that is safe for the battery chemistry selected, up to 10 amps max.
    - Davo1111 on 20/04/2023 - 19:40
      
      I don't think it does what you're thinking. The manual says it sends 10 amps, not up to 10 amps. I think it reduces the amps purely on voltage
      - antik on 20/04/2023 - 22:45
        
        @Davo1111: It does exactly what I said. It’s a 10-stage smart charger that adjusts amperage dependant on which stage and chemistry is selected. Even has a 6V mode at a reduced 2A output. End of the day, any car battery can take a full 10A. How many amps do you think an alternator charges a battery at?

Still not quite clear what it does? Can someone please help? For example, if I got flat battery and use this charger to charge the flat battery, will the battery be charged and can last another one or two year? In that case, we don't need buy new battery any more? Am I right? Thanks in advance.

  It depends how far gone your battery is… if you use this charger before the battery goes flat then it should prolong the life of the battery
  - garage sale on 20/04/2023 - 08:18
    
    lead acid batteries plates break down when fully flattened and the more that happens the more the plates break down….. if you are constantly having a flat battery it’s faulty and will keep deteriorating ….. rejuvenate modes …. if you have a clear plastic battery you can see build up doesn’t disappear,
    if rejunivate modes work, car manufacturers would add to software in car charge system so that batteries last longer under car warranty ….
    
    if battery is old and not holding charge, get a new battery or a cigarette lighter socket voltage meter and see what your battery does when not charging from alternator ….voltage after a drive and charged vs voltage next morning or when you get back from shopping or even if you alternator is reaching full charge voltage …….
  - bestdealsonly on 20/04/2023 - 11:08
    
    So if my battery was flat and I jump started and drive 50km, Shouldn't that automatically charge the battery? I did that and next day my battery is flat. Does that mean my battery is gone?
    - Malik Nasser on 20/04/2023 - 14:05
      
      Your car has an alternator, which charges the battery whenever the car is on. If you regularly drive your car, it will maintain your batteries state of charge (SoC) at around 100%. Over time your battery will start to break down, so the state of health (SoH) of the battery will go down, and eventually the battery will not be able to hold a charge.
      By the sounds of it, either your battery has died, or possibly your alternator could have died.
      My bet would be the battery has died (highest probability scenario).
      You can get battery testers which also can test your alternator function, if you wanted to do it yourself, or otherwise just take it to your mechanic to check.
- Widget on 20/04/2023 - 00:57

  It's a battery charger. It charges flat batteries, so if your battery went flat, it's designed to charge it. Now, if your battery went flat because it can no longer hold a charge (old battery, battery has been flat for long time), well, it may be damaged. You could use some of the features the charger has to give the battery life, but who knows.
  
  As for the length of time the battery will last if it gets fully charged… who knows. Could be a day, could be 10years.

When charging car battery, it's best to leave it connected in the car and charge it directly there.

I made a mistake of taking it out of the car and charge it. When I put it back in the car, somehow it shorts my ECU and I got rough idle as the ECU need to re-learn the timing. Took few mins of driving for the ECU to be back to where it was.

  Anyway around $100-120 would still be a good price these days, inflation.
  
  Cheers.

Yes I agree mate with inflation its not a bad price between 100-120.

Does anyone know what's the smallest size inverter that will run this reliably ?
I have a couple of 300w Jaycar invertors plus batt and solarpanel to charge 2x100ah deep cycle + other stuff around the house , was just wondering if I'm under charging ,
for some new century 2nds that are struggling to hold a charge after recharging .
