Cue to today, I fitted a brand new Yuasa battery and followed the correct removal and fitting procedures. Goes for a long drive and had the same fault again about 20 times. Tested battery with and without engine running and seems to be fine. Although I checked again just now under load with engine running and I was only getting a reading of 12.2V.
If the battery connectors show no signs of damage, then it is time to charge the battery. Ideally, you should use a BMW Battery “smart” charger to ensure that your car gets just the right amount of charge. There are both 12V and 24V batteries equipped in BMW cars depending on the model, so make sure you know what type needs to be charged
Battery failures caused by sulphation, wear and tear, deep cycling and physical damage are not manufacturing defects and are not covered by the Yuasa guarantee. Under normal operating conditions, a battery cannot become
What to do next – It''s likely the main bettery will need to be replaced but it''s important to understand why. Is the battery older (more than 5 years) or is the system not charging it correctly.
Whilst a flat battery during a pandemic lockdown is not at all surprising, it''s happened three times now on my wife''s 2013 1L Ecoboost Fiesta which doesn''t seem at all right.. I am charging the battery as we speak and, once complete, will be taking parasitic current measurements as the obvious first step towards finding out if there''s anything amiss on that front.
UPDATE: Honda UK have authorised a fix but it''s not the control module as first thought. They have got to replace the whole battery at a cost of £23k ! The dealer also has had to hire a crane at a cost of £1k to lift the battery out. Honda UK are sending out technicians this week to do the work so hopefully I''ll get it back next week.
The light will show up on the dashboard when you do not have a lot of battery power left and should be switched off once you have charged the battery. In some cases, this light might be illuminated even after you have fully
My car battery went entirely flat and the household battery charger would not begin to put any charge in. The household insisted this is a fairly new high quality charger and is made to only input charge when there is a small amount of charge left in which it does. The AA who came said this is rubbish and needs throwing away and I would have thought when the
Left car on my driveway for 3 days battery went flat. Every fault light flashing, total malfunction of Hybid system.

Under normal circumstances, the car battery warning light illuminates temporarily on the dashboard as you switch the ignition (or press the engine start button) to ''on'' and then it should go out shortly after the engine has started.
The internal short circuit (ISC) fault has been considered as one of the most serious problems, which may pose a threat to the operation safety of the battery system. To solve this problem, this paper proposes an ISC fault diagnosis method based on multi-feature recognition to distinguish aging and ISC fault.
Q4：Why the system show battery open circuit warning? Q12: Why battery does not discharge full power even though power limitation is 100%?(lithium) A: The charge/discharge power will limited by both by inverter and BMS. For example, the discharge power limitation for inverter is
e) Check all fault indicators by simulating a FAULT condition in each zone either: i) Removing a detector from its base. ii) Disconnecting the local circuit from an ancillary unit''s circuit. f) Visually check the condition of the controller and other ancillary equipment for signs of moisture ingress and other deterioration.
What symptoms indicate a battery problem? The battery''s main function is to start the vehicle, so the most obvious symptom of a bad battery will be failure to start the car. If you turn the key or press the start button and nothing happens, it''s a

VM shows 13.8 volts at battery while engine running, battery showing 12.5 after sitting for a couple of hours, also confirmed the charging system is working as I drove it about an hour or so to see if fault would reset. Does the BMS need to be reset due to the fact that battery was disconnected during the Alt install, or could the BMS be defective?
I have a problem with the battery charging system. When you start the car after a few seconds on the dash shows up a message - Battery Charging Fault - with battery indicator ON (RED).

Could be another fault, like a dodgy ground connection causing dim rear/brake lights and they''re just being idiots by assuming it''s the battery. Very old battery though, i''d strongly doubt a 5 year old battery will last another winter. I''d be tempted to by a new one, fit it myself, take it back and say "right where''s my certificate?"

The battery warning light is a light in the shape of a battery symbol. If you start your car and the battery light appears, there's no underlying issue. It's normal for the light to show when you first turn on your car – it'll disappear after some seconds. However, if it appears on your dashboard while driving, you must act.
You can check the battery's voltage yourself using a multimeter. If the battery light has been triggered but the car is still running okay, there may still be underlying problems such as corroded terminals or a worn alternator or voltage regulator. Sometimes the voltage issues are intermittent or other symptoms take longer to show.
You now know the causes of the battery light on your car, which include a bad battery, faulty wiring, and much more. But with the fixes above, you'll be able to solve the battery light issue and have your vehicle functioning as normal.
This is probably the most common cause of the battery charge fault. Over time, batteries can get damaged, the terminals become corroded, or the cables get dislodged or damaged. If this happens, the battery will no longer be able to hold the charge from the alternator and gradually lose power over time.
