Citroen C4 Cactus no power

Rick1977

Hi, 
Before I look at calling someone out I just wanted to check to see if anyone can give me any advice. 
I've got a 2015 Citroen C4 Cactus that has totally lost power.  We used it a few days ago so it hasn't been left for an extended period of time.  But just went to use it and there is no power at all,  remote unlock doesn't work, no dashboard readouts, when turning the key nothing happens at. all. Does anyone have any simple advice to try before I call out someone? 

Thanks in advance for any advice.

Got a voltmeter? Checked the battery voltage?

Hi Adrian,
I don't I'm afraid. Is there any other way to check the battery? 

thanks

Battery is probably flat.
Two wires and a bulb if you don't have a voltmeter to test it.

See if any of your friends or neighbours have a battery charger that you could borrow and give the battery a charge for about 30 minutes then see if you get any dash lights. (don't try starting the car after such a short charge). This won't be anywhere near enough to give the battery any sort of decent charge but it will at least see if it is the cause of the problem.
If the battery is totally dead them it may well need replacing as if it goes below about 10 volts, it can often totally wreck it.

Similar happened to our other car yesterday. Even though we have alternated the use of both cars to avoid the battery getting flat, the battery went completely dead yesterday and central locking wouldn't even work. The battery was reading 2V on a voltmeter. I charged it up using a trickle charger (https://www.argos.co.uk/product/7604351?clickSR=slp:term:aa%20battery%20trickle%20charger:1:39:1) until the battery was about 11.8V which took about 2/3 hours. All the central locking then works but still too low to start the car. I then jump started it using a battery jump starter (https://www.70mai.com/en/70mai-jump-starter/). After this, I took a 30 mile journey to make sure the battery is properly charged. The car battery has been okay since and the car started okay every time now. If you are happy to wait, you can just wait for the trickle charger to fully charge the battery without needing to jump start it. 
Please note that because the battery voltage was too low at the start, the AA battery charger initially showed battery fault message with an alarm. The trick is to switch off and on again. Do this until the battery has enough charge in it and the battery will charge normally.
