Hi all. I went to start my car (Grand C4 Picasso 2014) for the first time in a month (and only 2nd time since December) and the battery is completely dead. Fortunately I parked 6-8 inches from my left hand garage wall so I could just open my door to get my bonnet open. I've no idea what I would have done if I couldn't open the door (ridiculous location for the bonnet opening lever!). I connected my 12v Halfords battery charger and the red charging light came on. When I went back after 2-3 hours however there were no lights on at all (neither the charging nor trickle lights). I was very suspicious that it could possibly have changed anything in 2 hours but reconnected the battery to test. The central locking with the key didn't work (possibly the key battery) however after 30 seconds of a fast clicking noise, the dashboard did light up. Everything the trip distance, total distance indicators were set to zero (as you'd probably imagine) and there was a number of light illuminated like STOP / SERVICE etc. I didn't notice the battery icon but the dashboard only stayed illuminated for a short time. When I pressed the STOP / START button absolutely nothing happened at all. The dashboard didn't re-illuminate and hasn't done since. I'm not convinced that my charger is very good, it gets very hot and is very small, it just doesn't seem up to the job, so I plan to buy a new one anyway. I don't know if my battery has ever been changed either so perhaps I need a new one. In the first instance however, once I charge with my new charger (yet to arrive), should it simply start or do I need to go through a whole load of steps to reboot the computer etc? Thanks in advance, Chris |

I would say just try to start as normal. See what others say. | ||||

I've no idea what I would have done if I couldn't open the door (ridiculous location for the bonnet opening lever!). Virtually all cars now have this kind of arrangement for the bonnet release. The reason is so that the bonnet cannot be released when the car is in motion. There should be no issue starting the car but you will need to reset date and time, possibly language (it is likely to revert to French), and reset the speedo and odometer to miles. |

Thanks for the help folks. I'll wait for the new charger to arrive and take it from there. | ||||

If you can get the car into the sunlight you can buy solar trickle chargers that connect via the OBD socket. That may help. I've bought one from Amazon and am using it in both my C4 and my Wifes Toyota. Like you I had a dead flat battery but the RAC managed to get the car started, it then went again and this time they replaced the battery. I'm hoping the trickle charger will save me any more problems. The one I purchased is the AA 12V Car Solar Battery Charger 4.8W AA1432 - For Vehicles And Caravans - Battery Connectors Included, at the moment £36.99 on Amazon. |

That sounds really useful dmpzsn, thanks. I've ordered this charger which I think should do the job - Click Here - It should allow me to properly charge it this time and maybe leave it on trickle charge every now and then. I'll definitely look into the solar one tho, at that price it's a no-brainer. |

When you go to start the car, turn the ignition on and wait until all the pre-start checks are complete, about 20-30 seconds. Then turn the key to start the engine. Hopefully the engine will fire up and you can then check the language, units and clock. As for bonnet releases, the hidden location by the door hinges is almost universal. |

My car is 2014 and doesn't have an ignition that turns just the hole in the dashboard where the key sits sometimes (no idea what the point of this hole is tbh). The only way to start and stop the car is by the big STOP/START button. |

As for bonnet releases, the hidden location by the door hinges is almost universal. Turn the electrics on by pressing the button without pressing the clutch pedal (manual gearbox). I would guess with an auto box you press the button without applying the brake. Thanks BigJohnD.

If the battery is original it is likely it needs renewing. Once a battery of that age has completely discharged it will be difficult if not impossible to recharge.My own 2008 C4 stands idle for sometimes months and I have never had a problem with starting as the economy mode kicks in. | ||||

I'd renew the battery anyway, leaving them uncharged for a long time is a killer. It does a car good to give it a start and drive once a week, even just along the road and back, stops everything sezing up. |

Thanks everyone. I'll try the charger and then go for a new battery if necessary. Any idea what sort I'd need for one of these? It's a 1600 with Stop-Start. Thanks |

To be honest, I'd just change the battery, it'll let you down at the most inconvenient time. | ||||

That's no problem, I did check with both the Toyota and the Citroen main dealers before I bought one, both said it was fine but to make sure it was disconnected before driving off. |
