Default Battery question

I went out to start my cdt this morning for the first time in a fortnight, when I turned the key all I heard was a single click, tried again same result. I left it a minute, tried again and the car fired up perfectly. The battery is a Yuasa 3000, just a year old and is still showing a green indicator for good condition, any thoughts? .

The first step is to take it out of the car and put it on a conventional car battery charger (say a 4Amp charger) for 24 hours. Then reinstall in the car and see how it behaves over the next few days/weeks.

Hopefully it is just a case of the battery being discharged due to lack of use.

Thank you for your advice, the thing is why did the car start quite normally on the third attempt, and why is the batteries built in indicator showing good battert state?.

It could be all sorts of reasons, including that the glow plugs will have drawn a fairly hefty current when cold thus perhaps depleting the battery to a level below the required threshold.

Hi Alan.
What mileage as your car done now, if over 75,000 then do not rule out the contacts & plunger in the starter motor, check the battery see how much charge is in it.

Also remove the spade end on the starter motor and clean it up, pinch the spade end a little over time they work lose due to vibration.

If it is the starter which my bet is on then click the link below.

Also as a maintenance check click the link.

The car has only covered 65k, when I have had flat batteries in the past the ignition has made a multiple clicking sound and no way would it start, on this occasion just a single click. I then used the digital in car check, 19/9 which showed 11.4 volts. The car then started quite ok on the next attempt.

HI Alan.
Yes that is why I said it maybe the starter as you get one click and will not start, but low battery as you say, (multiple clicking sound and no way would it start,)

Also word to the wise if the battery do not keep trying to start the car please read link below from Russ.

One click only & working fine afterwards? I put my bet on a failing starter solenoid or motor.
I've had the case very recently: in the beginning, months ago, it happened only once a month maybe, but since the beginning of last month it was worsening & becoming stressing.
My AGM battery is nearly new and very powerful.
So I swapped for a good refurbished starter NAD 100952 to feel relieved:

Also check battery terminals for tightness
