• ANY - New Battery Charging Behaviour? 10 Nov 2017 (Forum)
  So by my reckoning its had about an indicated 70Ah at this point.  So a couple of questions Is this normal for a freshly flooded battery, which this was supposed to be? Whats the optimal charging regime for a new battery? As low current as possible, as I've usually done with "dumb" chargers in the past) or trust the chargers alleged smarts and set it to "car"?
• Vauxhall Corsa B - Dashboard on/off with out key in ignition 24 Nov 2014 (Forum)
    I tried few things but couldnt find a solution. I finally took the courage and took it to the local vauxhall garage, who are saying a faulty battery is causing it. I feel they got the problem the other way around.. since the dashboard lights come up randomly, it is draining the battery. Thats £200 quid for not knowing what is causing the problem and a battery replacement.

• Mazda 121 - 1.3 - 1996 - Draining Battery 25 Feb 2011 (Forum)
  All off When I put a multi-meter acoss the live battery terminal to earth, it indicated a  full short, which is a little worrying... Should that happen, surely that is dangerous? Disconnected the alternator, short still there. There are 3 wires going to the positive terminal, a chunking big one that has the battery connection on the end and 2 smaller cables connected to it.

• Volkswagen Touran MPV (2003 - ) - Warning of impending car breakdown 8 Feb 2010 (Forum)
  Needless to say, the battery had not been charging all day long. The alternator belt had come off the pulley - hopefully the VW garage will have worked out why when they get around to looking at on Monday. Now, I feel peeved that a system which provides a nice clear warning about a drop in engine coolant level cannot similarly warn the user that the car is failing to charge its battery and is in imminent danger of coming to a complete halt.
• Peugeot 306 (1993 - 2001) - 01 2.0 starting problem 306 2.0 HDI 27 Sep 2009 (Forum)

• 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.
