• Ford Fiesta (1995 - 1999) - 96 1.1 Flat Battery 26 Jul 2009 (Forum)
  She started fine, the charging light going out after about 5 seconds. It has had a new alternator fitted by the previous owner as he said the battery wasn't holding a charge. Today the battery went completely flat while my daughter was driving it. The RAC man said the battery was showing 7.1v and, in his opinion the charge light wasn't working at all.

• Mini Flat Battery : o ( 11 Jun 2007 (Forum)
  We bought a Mini three months ago, a 1991 998cc. After a while the battery died so we bought a new one which was fine for a week or so, got progressively slower turning the starter then was flat. Check for anything that could be draining, removed interior light bulb. Gave it a good trickle charge and in the interim fitted a battery isolator switch which has been used every time the car has been left.

• is my battery dead or something worse? 13 Sep 2003 (Forum)
  While I was driving, the electrics were not 100%, e.g. opening the el. window made the headlights dim. Overnight, I borrowed a battery charger and attached it to the battery, but after half an hour or so, the charger reckoned the battery was fully charged, but still no joy with starting the engine. I'm a bit clueless and hope to get a bit of advice before I take a garage's word for it that I need a new this and that.

• Ford Focus (1998 - 2004) - 99 1.8 Starting issues - crazy dials - battery pro 15 Jun 2008 (Forum)
  At 80k miles on the original battery, I'm obviously overdue a replacement so I'm happy to replace it as a first attempt to sort this out as it's likely I'll need to replace it fairly soon anyway, but it's odd that a fully charged battery is still causing problems - I don't really know enough about car batteries and how they behave, but I wonder whether a new battery will behave any differently ?

• Mini One 2003 - ECU Battery? 21 Feb 2016 (Forum)
  They tell me I need a new door latch but I am reluctant to spend any money on the car as I am selling it for Spares or Repair. They refused to fit an isolator switch to enable me to stop the fault from draining the battery when the car is not in use. Their reason being that "they think" the ECU has a back up battery so I will only wear that down if the main car battery is disconnected. Does any one know if a Mini One 2003 contains a back up battery within the ECU??
