Sounds like you're sorted. But just wanted to put in another vote for the Ctek MXS5.0 from me. They are fantastic chargers. 

Batman: 

 

Van is regularly used but battery not charging

is it not charging or getting discharged overnight?

had an issue with a previous car where a fault in the alarm system was discharging the battery.

got a cheap battery charger from sca then, which is still alive now (years later).

latest repco flyer (front page) has a deal on the Ctek MXS5.0 - $139 gets the MXS5.0, rubber case, and 500mAh power bank

Can you upload a photo please? Website is just showing a D.I.T With D.A.D. flyer which I assume is the old flyer.

FYI - Repco has a ctek value pack of a MCS5.0 battery charger, a rubber protector and a 500mAh power bank for $139. That price is from 26th Aug - 6th September.

 

Just to be clear, are you saying that this deal is coming onstream in a couple of days? Currently Repco only have the MXS5.0 listed (at its usual exorbitant price, well above what the Ctek website has it for!). I've been looking for one myself and that would be a good price, and no freight charges on top :-)

That is correct. That price is from 26th Aug - 6th September, and is from the front page of their flyer (that is not active yet).

Cheers.

"Yes I've called the mechanic but they are fully booked for a while."

You need an auto electrician, not mechanic.

You shouldn't need to charge the battery on a vehicle in regular service.

Yes. Take it to an Auto electrician. They will have the tools required to correctly diagnose the problem.

Another thing to watch is a phantom power drain. 
Some system that is on and draining power while car is sitting in garage.
Interior light or a boot light you can't see that was switched on by shifting load or forgotten.

I had the relay for air-conditioning clutch stick, so had a constant few amps drain while sitting.
Can be intermittent, so may randomly happen then release when car bumped, door slammed, just to make finding it tricky.

Anyway on replacing the battery ( it was old anyway ) there was a dull clunk when the battery was connected,
did not think much of it until new battery started going flat. 
A bit of internetting and this suggestion came up.

On further inspection the car was drawing a few amps when ignition off.
So with that clunk noise , looked at aircon clutch and it was pulling in. 
Found the right relay , tapped it , Aircon clutch released and large drain was gone.
Swapped the relay to the horn until I got it replaced just in case.

Charging with the battery in a car like most of the maintaining chargers do is always going to be slow. You will never see 16A on a charger that can do that on a typical car battery once its up past the initial wont even crank a car level of discharge.

To put high currents into a non dead battery you need to bring the terminal voltage well above what the rest of the stuff in a car will deal with. Thats why the large chargers have it selectable for those modes, and they're called battery boilers because that is what happens if you forget about them. The cars electronics will not appreciate the sustained 18+ volts across them and will either clamp it and things just get hot, or blow a fuse if you use an actual high current charger.

Anything that can run on the car with things connected still will only be able to put a few amps into a car battery sized battery since the terminal voltage will stay in the 14.5ish range where things are not going to get unhappy. That is also why driving a car around does a crap job of charging a battery up even if you rev it.
