CTEK Battery Charger 12V 0.8A - $55 at Repco

81

A good price for a quality branded small charger, regarded as one of the best brands you can get. If you're charging larger batteries it might be worth getting a higher amperage model, but for small batteries or trickle charging, this is a great price. You can charge large batteries with small chargers, it just takes forever.

Can also get the 3.8A model for $98.80 and the 5A model for 112.45, but the 0.8A is the real bargain here.

  • I've had 3 CTEK chargers. 2 have failed and been replaced under warranty. The first replacement has now failed out of warranty.

    Bought A Century charger on special from Supercheap at Christmas for about $115. So far in happy with it.

    • That's really unlucky. I've had mine for years and used regularly on an old motorbike. Never had a hiccup once.

    • I wish my electronics skills were good enough for me to repair myself. Also got a small charger with the Jetski I bought secondhand. DOA probably from all the salt.

      I've inspected for obvious faults. Replaced a suspect diode and capacitor but that's my limit unfortunately.

      • Had a ctek 3.8 fail after 6-7 years, luckily it was only a broken capacitor inside so $1 fix.

  • 5A shows $104 for me

    • Same, in WA

    • 5A one would be a better purchased. I have a few of these and they are going strong

  • Only 0.8amp, sounds useless. What battery or electronic devices do you use to charge that their default chargers don't do? Definitely should buy the bigger amp chargers if planning to charge motorbike or jet ski batteries. Recently bought a cheaper brand Xcell 9-stage 8amp AC-DC charger for under $80, works well topping up two car batteries.

      They're for trickle charging, how often do you need to full recharge a whole battery? For other people we have 1 proper strong fast and then the cheaper trickle ones for cars you drive once in a while.

      I guess you could rotate the charger.

      • How often do people trickle charge their 12V batteries? If you do, won't you just use a higher amp charger, since they are smart staging chargers they can also trickle charge, plus they can also fully charge the batteries when needed. You just need to buy one proper higher amp charger, instead of buying another like this ultra low amp charger. Not like you are maintaining a whole fleet of cars anyway, if you are, you should buy several higher amp chargers too.

  • I have had a 7A and a 5A unit for a few years. No dramas. Although the 7A has a better UI - it has a "do nothing" mode where it is just "on", whereas the 5A starts charging as soon as power is supplied. Pretty sure both have memory, if the power fails and comes back on, they keep going with the last setting.

  • I have a xs0.8 trickling my bike whenever I'm not riding it. $59 in August 2015…. Not much of bargain here unless prices inflated in 3 years.

  • From personal experience having a higher AMP charger means you can also use it as a jump starter if battery is flat.

    Couple times I've wanted to drive the weekend car to only release battery doesn't have enough charge to start. Give it 10-15 minutes on a CTEK MX5.0 charger and you'll be right to be off on your way. Saves you finding somebody to jump start your car.

    Also with the non branded/generic ones from ALDI and alike, you won't be able to replace battery clips if they break. CTEK generally have pretty good spare parts if you want different adapters/plugs.

    0.8A ?!
    Better ones are $7 on ebay, and sold as for motorcycles.
    A proper car battery charger is maybe $25.

    e.g. 20A Au stock, $37 delivered:

    Charging lead-acid is not rocket science.
