• Renault Clio '02 changing key battery 23 Sep 2005 (Forum)
  Hi I'm trying to replace the battery in the key fob for my wife's clio. Is it a question of levering the key apart with a screwdriver or does the key slide apart somehow. Any help greatly appreciated before I manage to wreck it!!
• Anybody a dab hand with Tractors? 3 Sep 2003 (Forum)
  Hello all, How do you check whether a 12 volt car battery charger is actually charging... Which is to say whether it's working or not. There's a fairly new battery in it and I'm wondering if it's the charger rather than the battery. Any help appreciated.

  My daughter in-law has a Ford Fiesta 1.0 litre EcoBoost on a two year PCP plan with a major Ford Dealer. Over the last 18 months the AA has recovered...
• Ford Focus - Car battery charging 28 Apr 2013 (Forum)
  This has resulted in one very dead battery, and I've had to jump-start it quite a few times in the last month.  This week I decided to crack out the maintenance charger... It seems to work really well. I plugged it in yesterday to charge the battery.
• Nissan Terrano II (1993 - 2005) - (93-05) 2.7TD - Is my alternator on the way out? 21 Jul 2009 (Forum)
  I'm sure the battery is ok, its a heavy duty battery which is only 6 months old! This is what happened next. I called out the AA home start service. The mechanic told me that the battery was fine and that the alternator was to blame.
• Starter motor firework display 3 Oct 2002 (Forum)
  hello > I have a renault 5, I replaced the starter motor with a used part which i am assured is in good order. During removal of the old starter i failed to disconnect the battery (stuupid!} and had a lot of fireworks, consequently i replaced the burnt out negative battery lead and the negative lead from the battery to the starter motor housing located at the remote end of the starter motor (away from the the starter armature end).

  How should I proceed with the garage that sold me a BMW 118i with a faulty battery? 15 Dec 2010 (Ask HJ)
  I bought a 2-year-old BMW 118d last May from the local BMW dealer. It is a fantastic car, but the stop-start function didn't work from day one. I reported...
• Volkswagen Polo (2022) - Battery Charging - can you do it yourself? 13 Aug 2025 (Forum)
  It would seem that VW don't want anyone to charge the battery in my car except an authorised dealer.  Given the extensive electronics I can understand their nervousness!  I have what I think is a very good battery charger (Victron Energy Blue Smart) which provides a wealth of charging options and appears to have a very good auto charging facility.
• Honda jazz auto/iShift - Battery draining 5 Mar 2020 (Forum)
  Could this be draining the battery? I can’t see how to turn this light off. The AC is set to OFF so I don’t understand why there’s a light on. It’s a 2010 Honda Jazz Auto/iShift model
• Mazda CX-5 - battery change 8 Feb 2019 (Forum)
  The car in question is a 2-litre petrol 165PS with stop-start. My 2014 example will need a new battery at some point. I'm trying to find out if it's a DIY job or not. Various Mazda owners' forums aren't being much help. One chap is suggesting the stop-start system will need re-setting after a new battery is fitted.
• BMW 3 Series Compact - New Battery for Old Car? 31 Aug 2018 (Forum)
  I have a sixteen years old BMW which is fundamentally very reliable once it gets going! The battery is a two year old Varta which is very "iffy" It charges up but does not seem to hold the charge and test show no obvious electrical leak.  After a charge it dropped  to 10v when (not) starting so I intend o get a new battery.
• N/A - Battery Warning - Classics And Low Mileage Drivers 5 Jun 2017 (Forum)
  In some ways it makes sense as a classic left standing and taken out a few times a year is quite demanding on the battery. Similarly a car that only does a short supermarket trip every week.
• Buying laptop battery online. 30 Sep 2011 (Forum)
  Hi,   My Dell Vostro's battery is dying. It lasts around 10mins when not plugged into the mains and has given up warning me it's reached critical until after I've turned it back on! (not helpful in the least!)   Can anyone recommend an online source of genuine Dell batteries?
• Ford S-MAX 1.8TDCi - Flat Battery After New Pads And Discs Fitted 30 Aug 2011 (Forum)
  After replacing the front discs and pads, a few days later the battery was completely discharged. After recharging and reconnecting the battery I noticed that a motor was running. I traced this to the ABS pump motor, this was confirmed by removing the 40amp fuse protecting that circuit, Any ideas what has caused the ABS pump to continue running even when the key is not in the ignition, has it anything to do with the replacing the front discs and pads?
• Citroen ZX (1992 - 1998) - 92 1.9 battery light stays on :-( 20 Nov 2009 (Forum)

Absolutely silent when you turn the key Battery Light on dash stays on "all the time" even with no key in ignition Only thing I did just before this fault was replacing the alternator/power steering belt but it did start fine once afterwards?

• Peugeot 406 (1996 - 1998) - 97 1.9 TD cooling fan won't stop 14 Jan 2009 (Forum)
  The Missus noticed this at 3.00 this afternoon, when she got out and locked the car. Was still running when I got home at 8 !! The battery is almost flat and the only way to stop the fan was to disconnect the battery. Have placed the battery on charge overnight and shown her how to disconnect the battery (clever screw thingies) but I need to find a solution tomorrow afternoon.
• Mercedes Benz B-Class (2005 - ) - Key fob battery 29 Nov 2008 (Forum)
  The buttons on the key on my wifes B Class Mercedes stopped functioning. Popped round to the local Mercedes dealer and was informed that the batteries were £5 for two. I said I was expecting him to give me one not charge me. I fefused to pay their price, on the internet the most expensive I could see were £1.69 for two including postage. The same batteries, Panasonic CR2025 as original.
