• Peugeot 306 (1993 - 2001) - 01 2.0 starting problem 306 2.0 HDI 27 Sep 2009 (Forum)
  drove the car round the block with the battery still connected and it cut out although the 12v battery was still ok, not flat. Are the tank pumps running constantly when the car is running or intermitantly? have i flooded the engine by having the pump running canstantly??
• '04 Corsa battery charging problem 18 Dec 2007 (Forum)
  Any thoughts on this battery charging problem? The car is an 04 1.2 Corsa, warranty ends in May 07. When we got it at one year old the battery green float was not showing, however after some days and a few miles it was showing.
• Yuasa battery question 27 Aug 2025 (Forum)
  The young man explained that it showed I was driving high mileages (which is classed as over 12k pa). The battery was in a Toyota MR2 that is garaged in winter and on the road for the summer months. Over the winter it is connected to a CTEK conditioner. Since March it has performed perfectly. It failed suddenly whilst driving, luckily close to a local and trusted garage.
• Kia Niro 2018/68 - Fuel Consumtion of PHEV 5 Aug 2021 (Forum)
  On normal (flattish) motorwars, with the aircon on the car automatically recharges the battery at the rate of up to 1 mile per 10 run. Once the battery is recharged to 35-36 miles, I switch back to electric until the battery reading goes down to approx 15 miles and then I repeat the process.
• Honda Civic - Battery terminal left loose ... 1 Mar 2020 (Forum)
  After a body shop repair a couple of weeks ago, the car wouldn't start this morning - just completely dead. AA called, who found that the battery terminal was resting on the battery and making a very loose connection, not bolted on, and the terminal cover was sitting on top of the suspension housing a few inches away. It probably finally fell off when I pulled up on to my drive last night.
• Ford C-MAX 1.5 tdci 2015 - OBD 2 "engine service now" message 14 Jun 2019 (Forum)
  I bought a ford C Max 1.5 tdci titanium 2015 . Stop/start. No key. Done 300 miles in it with no problems, I did notice the battery wasn't holding charge for very long. I replaced the battery with the same type. Making sure I disconnected the positive terminal first, before disconnecting any other wires or sensors.
• Citroen C2 GT 1.6 2004 - Mysterious noise that is draining my battery 13 Jun 2016 (Forum)
    This continues at 35/40 sec intervals until either the battery goes flat or I return to the vehicle.   It's as if the car is trying to constantly kill power to something, but there is nothing running, so it just keeps going.
• Honda Jazz vs Toyota Prius 27 Apr 2015 (Forum)
  I am thinking about owning the car for ten years becasue this is how long my last used car (VW Polo) lived. My preference is the Prius. My concern here is the Prius battery. I have come across posts online where they have died after a number of years http://priuschat.com/threads/hybrid-battery-survey-gen2-prius-2004-2009.132362/ I read an article saying that it is not the mileage that kills the battery but the length of years and climate.
• Ford Mondeo ghia tdci 2007 2L - Damsel in distress Ford mondeo start up issues 16 Nov 2013 (Forum)
  I'm at my wits end, it all started with dmf going got this replaced with starter etc and ever since egm light been on start up fine for last month then One morning car drove fine down to shop then dead battery 5 mins later on start up, got jump start battery reading 8v,  wouldn't start after that long enough with jump start so had to get it towed,  Mechanic advised New battery but replaced with lead alkaline, I have read it needs to be silver calcium due to smart charge and I believe this is part of issue as 24 hours later car won't start again but when new battery was installed it read at 14v but I read this voltage would indicate smart charge faulty somewhere as should read around 16v?
• 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?
