low battery warning?

Recommended Posts

Even after a long motorway run if i mess with the radio or dash cam for more than a few minutes with engine off it shows low battery warning on dashboard?

Is this just over caution or is it a common fault?

 

Thanks in advance!

A few minutes? While the system can be over-cautious that sounds like a fault. Could be battery on its way out or could be that the battery isn't getting fully charged.

Do you have any voltages?

My car used to do this frequently, like yours, even after a long drive (Somerset to Dover) the message would come up after a few minutes. I had the battery replaced when the car was 4 years old in 2015 and it's been fine since.

I have had a owned a Mondeo 2.2 Titanium x sport and a Kuga Titanium in the past and both have displayed the message low battery it was the key remote battery needs replacing

Try replacing the key remote battery in both key remotes and the message should clear

I've had the battery checked at a garage and is giving out correct voltage and is ok according to them!

I never thought of that, according to the handbook it shows car battery not key fob batteries?

Voltage alone is no indicator of battery condition it needs a load test

You're correct, the dash will say if its the key fob battery or the car battery.

You could take the battery off and charge it overnight and see if that helps, if not then it probably needs replacing if it's over 4 years old.

For about a year now I've been getting the odd Immobiliser active, low battery, poor starting but never quite failing

Head unit would keep forgetting attached phone.

Everything solved by a new battery. Even though when tested they advised that nothing was wrong with.

Found out that the battery was 7 years old.

A ropey battery can and often DOES cause no end of weird issues with modern cars.

haha, since I posted in February, I got the Low battery message last week. The battery was fitted just over 3 years ago and is a Ford branded unit (made by Varta). 

I decided to take it out and tested it with a load tester (indicated ok) and then charge it on a mainentance charger for 2 days. Whilst that was charging I fitted an old Halfords Calcium battery that I removed from my old ST24 (bought new in 2012 but charged regularly since removal), the battery was slightly taller so I had to remove the battery box for it to fit, it started the car fine and didn't give the low battery message (but it was only fitted for two days). After replacing the Ford battery, all was well for about 5 days but then I got the message again. Just like the previous (original) battery, it has never failed to start the car, but it does switch off the stereo after about 10 mins when the engine is not running.

I've been reading this topic with interest as my car on occasion comes up with the same message. I put my battery on charge overnight and it has only flashed up this warning once since, but the stop/ start has stopped working.  Any idea if it could be connected or is it just a high ambient temperature ?

I believe if the system thinks the battery is low then one of the first things that stop  working, to save power, is the start/stop function. I don't have this so I can't say much more than that.

I charged my battery again yesterday and fitted the CTEK quick connectors to the battery terminals, so I don't have to remove it next time.
