  One of my work-mates has a early 90's 1.6 Primera. Last night, he removed the battery to charge it, but when it was re-fitted this morning the car will not start. The engine is spinning over on the starter but will not fire, and yes there is petrol in it. Any ideas anyone???

• VW Fox 2009 - How do I jump start this car battery? (VW Fox 09) 23 Feb 2020 (Forum)
  Hi all, My VW Fox has drained its battery and I'm stumped as to how to jump-start it. I've taken off the battery cover - pictured in https://i.imgur.com/BybCGa8.jpg - but there's still no way to get the positive dragon clip onto the positive terminal that I can see.
• Chrysler Grand Voyager XS - Will higher AH battery damage car 27 Nov 2019 (Forum)
  I have a Chrysler Grand Voyager XS which is suffering from this problem covered previously on this site about eating batteries. The batteries hold their voltage but the CCA gets screwed for some reason. In my last voyager which was not a grand version I put a Bosch S4 096 which lasted until I scrapped the vehicle.

• Mini Cooper Clubman D - Efficient Dynamics system 5 Nov 2012 (Forum)
  I have just had a new battery fitted, the car being 15months old with 7500 on the clock.   I was told by the garage that the battery had been damaged because I had done too many short journeys and I gather this is because of the efficient dynamic system.

  I have had a persistent problem with the battery on my C-Max going flat after about 1 week when not usyed.  The car has been to the ford dealer a few times but they have not been able to find anything wrong.  We have had a new battery fitted but this made no difference.
• Jaguar XK8 and XKR (1996 - 2006) - 97 4.0 adding GPS tracker - what connections to 1 18 May 2011 (Forum)
  I do have an 'old' tracker fitted to my other car (MX5, connected to permanent +12v) but that plus the alarm will deplete the car's battery within 5 days. However, the MX5's battery is a fairly puny gel type, so it's not surprising. Maybe a normal wet-cell battery will do better ? Thanks Frank

• Mercedes Benz C-Class W203 (2000 - 2007) - 03 2.40 Key won't work remotely 29 Oct 2008 (Forum)
  Both keys were acting up (requiring several presses/being very close to the car) when locking/unlocking remotely. So I replaced the battery in both myself. The key I usually use (and had it's battery replaced during at least 1 service) is fine. But the 'spare' was probably on it's original battery and possibly got completely flat. This still dosn't work even with a fresh battery.
• Decent/cheap battery charger? 19 Nov 2005 (Forum)
  With winter well on the way, I think it might be time I gave my battery a bit of a boost. I do a lot of driving in the dark and its quite infrequent, 2 things which don't help the battery much. I got in it yesterday, after it had sat a few days (and was also bitter cold) and it didn't turn over with its usual enthusiasm.
• Flat batteries & memory loss 18 Mar 2002 (Forum)
  By doing this this codes & memories are retained while you change the battery. I have gone through the circuit diagram for the carlton & it would put power back to the ignition switch. Obviously, if you have a completely flat battery they have gone anyway but batteries usually lose 1 cell first, not enough volts/amps to start a motor but enough to retain memories.
