• vw touran diesel suddenly dies 27 Jun 2006 (Forum)
  So my thoughts are 1.if it was a high resistance battery terminal ie corrosion it would get hot but why would that cause the engine to stop. 2. If there was a lot of drain on the battery and caused the voltage to drop significantly and cause the + terminal to get hot would that stop the engine. 3.

• How to test a battery ? 6 Jun 2021 (Forum)
  Obvious question, I suppose, but since I know a thing or two about electronics, how does one test a car battery ? Presumably under full load (engine, lights, rear screen heater), and then measure the voltage drop ? What should it be, given that it's normally 12v ?

  Anyone know if the original battery on a ford focus 1.6 auto needs topping up or if it is sealed? If it is unsealed I will order a Hydromoter. I can check tomorrow but it is too dark outside now.

• Audi Allroad - charging fault 30 Jul 2013 (Forum)
  Hi all. Having issues with the battery charging. When I turn ignition on the battery light doesn't illuminate and when the engines running the battery gauge stays at 12 volts but when you rev it a couple of times the gauge goes up and it starts to charge.
• Subaru - 03 2.0 Changing fob batteries 12 Jan 2010 (Forum)
  The remote alarm/unlocking keyfobs have not given out yet, but the batteries should probably be changed now at 6+ yrs old. Can anyone tell me whether this is a simple swap, or will there be immobiliser reprogramming issues etc to deal with? Thanks

• 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.

• 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).

• 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.
