Re: Ctek chargers?

I'm looking at buying and mounting a ctek 7000 in the rear cargo area beside my 40l Engel. When near 240v i'll run engel on 240v + plug the ctek into a spare cigarette plug with the special ctek cigarette plug adapter and charge the 2nd battery under the bonnet? Will this work? And yes i've run heavier wire from 2nd battery to rear cigarette plugs for the fridge and running aux gear.

This will work fine and will extend the life of the battery. I have a similar setup -though I use a different brand of charger.
While the Cteks are good, I would recommend a Xantax Truecharge2.

Re: Ctek chargers?

D4D,

I have a OZCHARGE 2/4/6 charger for use in my shed and it works a treat. I intend to take it with me when and if I ever buy a Genny but til then it's the ole 75AH Thumper via a Projecta DC20.

Re: Ctek chargers?

Leachy can you please clarify the need to disconnect the auxillary battery if charging from to rear cigarette plug adapter.

Your advice on 9-2-09 which I follow (If using an external charger it is good practice to isolate the battery being charged from the vehicle's 12v system.If charging an Aux. battery, for most installation types (Redarc, Piranah, ARB ...) you will need to isolate the Aux. battery from the vehicle).

Your advice on 11-2-10 to bilo33prado that I would like to try (This will work fine and will extend the life of the battery i.e. charging through the rear cigarette plug adapter).

Re: Ctek chargers?

I will soon be part of this prestigious club awaiting a CTek XS 700 from 4wdextreme on eBay :mrgreen:
Also ordered a comfort connect panel and cig plug adaptor. 4wdextreme is very quick to respond and also has the best prices going I can see along with several accolades on here.

Yes same here. c tek xs 7000 $205 delivered, same seller and i bought the cig plug adaptor for $29.50 delivered.
oh and a bought a CTEK XS 800 XS800 BATTERY CHARGER CAR BIKE BOAT MARINE for $40.90 + $10 postage to leave connected to my jet ski :mrgreen:

Mike,
If you are wanting to do this I would recommend the following things:

1: Have a way to disconnect the aux. battery from the rest of the vehicle. This could be a battery isolator switch, an anderson plug, removing a battery terminal, or in the case of a solenoid charging system, ensuring the solenoid is open.

2: The cigarette outlet should be wired direct to the aux. battery with heavy gauge wire (6mm2).

3. Run the fridge from the 240V supply and unplug the fridge from the aux. battery.

Note: Isolating the aux. battery and unplugging the fridge from the aux. battery are good practice, precautionary measures to minimise damage should the charger fail and send a spike through the system. It is still possible to charge the aux. battery with this isolation. It just means if there happens to be an issue with power system or charger the potential damage would be greater.

Re: Ctek chargers?

Thanks for the clarification. The way i 'm looking at doing it should work fine then. I'll disconnect 12v plug out of fridge when running on 240v and charging 2nd battery through cig plug. To be sure, to be sure

Thanks Leachy for your advice - most appreciated.

Re: Ctek chargers?

I was wondering if anyone has used the ctek comfort indicator and if so, how do you find it?
Thanks

Re: Ctek chargers?

Just got my Bushman fridge and am running it from my AGM battery mounted next to rear drawers. My Ctek dc-dc D250S recharges it from 11.5v (fridge cutout point when not being charged) up to 12.8v in less than two hours driving. Very happy.

I've also got an XC 7000 which I have used a couple of times so far. It gets very hot although works well. I even got lazy and connected it to the crank battery with the D250S running from it to the AGM in rear.

Between the two Cteks both batteries got fully charged in a couple of hours. (AGM was down to 11v. Crank was down to 12. 3v.) Most important point is to use at least 6 b&s cable if using Ctek and 2nd battery in rear to keep up those volts.

See my previous posts.

Re: Ctek chargers?

Bought an XS7000 and started charging a flat battery on an old vehicle I have. The battery is currently at 3-4v and I tried the normal setting and recond settings over a 4 hour period and it stays at stage 1 and find that it gets little to no charge. Note that the battery is disconnected from the vehicle.

I tested the ctek unit on my Prado's aux battery and it goes to stage 1 and then stage 2 almost immediately. I can also notice a slight bubbling noise coming from the battery.

So is the old vehicle battery a dud? Or should I keep the ctek on the battery on the recond mode for the 8 hours as mentioned in the manual?

Is it normal for the charger to get hot? It gets to the point where its still ok to touch.

As I mentioned before my 7000 gets very hot but still works well. Never did find out if this is normal.
But I wouldn't risk the expensive Cteck on an old battery that is down to 3v. It's had its day. Best to just turf it mate.
Don't forget to loosen off the caps when charging a battery to let the hydrogen gas vent off. (That's the bubbling)

Cheers.

Its a dud mate, turf it - no amount of reconditioning will ever bring it back to operational operformance.

Even if the voltage comes up and "appears" good, it will breakdown under load, nor will it hold charge over time... Scrap metal recycling time!!!

Hi All,

What is the better Ctek Charger to get for charging my Aux Battery on my Prado, when Base Camping and not driving the Prado?
I have a Exide CAL/CAL 95A/hr Battery as my Aux.

I have an ARB 47L Fridge and also a 12v Travel Buddy Oven, both of which drain the battery (more so the Oven)

I was looking at either the Ctek MXS 10 (10Amp Charger) or the MXS15 (15Amp Charger)

This would be use in-conjunction with a Honda 20i Generator that I carry, which also chargers my Tvan, when required.

Assistance would be greatly appreciated.

Stuart

Pretty obvious answer, MXS15
