• Nissan Micra - Nissan Micra problems, failing to start 26 Apr 2012 (Forum)
  Meanwhile i started to just not start first time, like it doesn't have enough power. I then got a fuse replaced on my battery. The car has now stopped just cutting out, it now just doesn't start first time like it has not enough power. I now have to have my foot on the accelorator when i start so it gets going. When i had the fuse changed on my battery they told me that the battery wasn't at it's best.
• VW Golf 1.9 diesel 2005 - VW Golf Diesel - battery flat no one knows why 4 Feb 2012 (Forum)
  We bought a vw golf, 55 plate 33000 miles, fsh, one owner, immaculate etc etc and after 2 weeks of perfect ownership woke up to find the rear lights on and the battery flat. The AA sorted that and we were ok for several more days, then the same problem happened twice in 3 nights. I noticed the nights were cold, this was December. We took it to our local garage that had the car on check for battery drain for 3 nights in their workshop and no problems were found.
• Vauxhall Astra MkV 1.7 CDTI (diesel) - Engine management light 11 Aug 2011 (Forum)
  I think this last information is key. It's an 05 plate, ex-poilice car with 158,000 miles and on the ORIGINAL battery. The built in hydrometer does not show green after sitting (ie, not charged) and that coupled with the extra cranking time leads me to believe it might be a battery problem. Does anyone think the same or know if there is any battery sensing ciruits that are very voltage sensitive that might cause this ?
• Morris Mini 1962 - Dynamo 24 Nov 2010 (Forum)
  My car has been off the road for a while and I recently changed the car to negative earth, which only involved connecting a battery charger to the car in place of a battery and 'flashing' the dynamo. I disconnected the charger and thought no more about it. At the wekend I connected the car up to a battery charger again to test the lights.

• Mazda Mazda 6 (2002 - 2007) - 05 2.0 Rear passenger electric window faulty 28 Jul 2009 (Forum)
  Following my flat battery episode detailed here... http://www.honestjohn.co.uk/forum/post/index.htm?t=75029&m=887105#887105 ...I subsequently found that the rear passenger-side electric window no longer works. Whether this was somehow the cause of the flat battery (whilst the car was left in my garage unused for 2 weeks), or happened as a result of the disconnection/reconnection of the battery, I do not know.
• Mercedes Benz E-Class W124 Estates (1985 - 1996) - 89 2.3 Current leak 10 Jan 2009 (Forum)
  Built in 1989. The alternator has recently been replaced and seems to be functioning okay. However the battery loses charge when running with the lights on; and eventually the car fails to run. (Not very convenient during these short winter days!) With the lights off the battery seems to get enough charge.
• Zafira DTI,Electrical problem 25 Oct 2006 (Forum)
  No problems for about three months then, the fault happend again, in the morning, attempted to bump start the car down a hill, no good, called out a breakdown firm, who jump started the car battery, pulled up at my house switched off and started no problems So, I replaced the car battery with a new Varta one, high crank output, last night, drove to work for a good hour travelling time and noticed the dash lights started to dim and the radio, switched itself on/off/on/off etc, so in the stupidity of me, I pulled over in the middle of nowhere and turned the engine off and stereo to recetify/reset the problem, turned key to start, battery flat, dash instruments filkering and alarm sounding.
• Fiesta 1.25 Zetec 1996 starting problem 16 Dec 2004 (Forum)
  The battery finally succumbed after another 2 months of non use. Jump started ok but battery would not hold charge (8 years old so not complaining). Alarm became very confused to the irritation of neigbours and did not want to reset properly until I discovered that manually opening and closing the passenger door would reset it permanently!
• Toyota Yaris - Tom Tom Toyota Sat Nav 11 Feb 2020 (Forum)
  Morning all, I have to replace the battery in my Tom Tom Toyota Eclipse II (AVN45429) Sat Nav. No problem removing the old battery, it's 3.7v 1320mAh Li Polymer but the only replacement I can find (so far) is 3.7v 1200mAh. Any views on whether this will do the job?
• FIAT Ducato Sevel X250 (2007 - ) - 03 1.9 flashing security light on dashboard 16 Jul 2009 (Forum)
  can anyone tell me how to connect a flashing led light, which is to be mounted on the dashboard, directly to the battery. I can't find an obvious route from the dashboard to the battery. Or is there another way to connect it so that it flashes to give the impression that an alarm is fitted. thanks
• Toyota Corolla (1992 - 1997) - 1995 1331cc - Immobiliser query 19 Jan 2008 (Forum)
  I have recently bought a 1995 Toyota Corolla Kudos Plus 1331 cc. The lady I bought it off told me that the immobiliser does not work. I need to fit a new battery to the vehicle. My concern is if I disconnect the old battery will the immobiliser 'kick in' and then will I be unable to start the car?

• Mondeo Mk3 Engine Cutting out 8 Aug 2005 (Forum)
  I had to disconnect the battery while I changed a panel bulb in the dashboard. Now everything has gone back together fine and working fine .... but when I slow down (to make a turn for example) the engine is cutting out. Has disconnecting the battery for 24 hours upset the ECU or something?

• Lexus RX300 (Harrier) - Lexus keeps going intermittently dead 25 Feb 2017 (Forum)
  Nothing works, alarm, no windows nothing. Then sometimes it will just fire into life. I checked the battery running and it's putting in 14.5V running and battery standing is 12.8V. So battery seems all ok. It there a main relay module on these cars which brings down everything? Any advice appreciated!

• 2003 Audi A4 Avant TDi B6 - Random Alarm - Flat Battery Diagnostic Socket 12 Oct 2015 (Forum)
  It seemed to cure itself, about a month ago. This morning the car had all its indicators going and a flat battery (18 months old) I'm guessing the alarm was triggered and as its not that noisey we didn't hear it. As its damp this morning I'm guessing this has something to do with it. Does anyone know of any common faults where I may look first?
