Default Diesel not starting - battery low?

All I get is a rhythmic 'click - click - click' and the dash lights dimming and brightening in sync with the clicking.

Now, to be fair, the Owner's handbook does say 'Cars that are used excessively for short journey motoring, may need the battery to be charged . . . ' and that is the motoring I have been doing lately.

Q1. Is the battery in need of a top-up ( the dipped headlights are reasonably bright) ?
Edit: the battery voltage is only 11.70 - the same meter reads 12.62 volts on another lead-acid battery

Q2. If there is a chance that that is all that needs attention, is it really necessary, as the handbook also says, to remove the battery from the car before charging it?


Thanks in advance!

You need to charge the battery fully, 11,7v will never start the diesel as it is essentially discharged, 12,62v is 95% charged.

Sounds like a flat battery as it would make that click click noise. Also, another issue that may make that noise is a dodgy starter motor.
I’d try and connect some jump leads and see if it starts if it does, then it’s the battery...I’d probably take it on a nice long drive and let it charge up and take it from there...

When it's down to only clicking and not even turning the engine slowly I'd say don't try jump starting it. There's too much risk to the electronics. Also driving it around after jump starting from a battery that flat is unlikely to put enough charge in to be useful. A good overnight to 24 hour charge on a good 'intelligent' charger is what is required.

Nice long drive is, unfortunately, a total waste of time and money.

As above post, 24 hrs minimum on a battery charger.

This is the SAME as 24 hrs driving on the road.---


REMEMBER it's TIME not DISTANCE to charge your battery.

You could buy several battery chargers for the cost of the fuel to drive 24 hours.----

What ever you do don't keep trying to start the car with a dodgy battery. This was posted some time ago by Russ:

DO NOT continue to try and start the car with a failing battery.

There is a possibility for the transponder chip in the key to become corrupted as it can scramble the rolling code with that stored in the immobiliser.

The engine disabled icon will display on the instument pack and you will no longer be able to start the car using that key.

To reduce the risk of this happening the best course of action is that if your car will not start as normal and the headlamps start to flash Don't continue to make attempts to start the car until you have charged the battery or replaced it if the battery has failed.

However should you be unfortunate and find that this has happened then any of the club members who offer the replacement key service should be able to re-sync the key with the immobiliser.

Thanks to everybody who has replied above.

No need to worry about hasty actions: I fully accept that the battery needs charging before I do anything else.

The problem holding me up now is that I do not have the security code for the audio system (Symphony radio/cassette on my car). I do have one half of the 'Security Information / AA Rover Assistance'' card that came with the car - but it is not filled in!

Thus, the questions now are

1. Am I dicing with disaster by NOT disconnecting the battery from the car before charging it? (I can't help thinking that my battery charger is much less powerful than a donor car doing a jump-start, which the handbook does allow).

2. Is there any way of finding out the security code for use in the future?

I often charge batteries connected. Make sure everything is off, I tend to leave a window open, just in case of central locking issues.

Connect the +ve lead first and then the earth. Trickle charge will always be best for the Health of your battery. I use a Ctec, which apparently restores a suspect battery and monitors the charge rate.

Sound like your battery is on its way out save the hassle of getting stranded and Change it.. euro car parts had a sale on if it’s any help.. From experience both my 75s within the space of a few months had battery issues.. and both where 3 year old.. the first like yours, I would charge it, top up if required etc it died within a month, the second on my Contemporary just collapsed.. had the receipt for that one and ECP gave me a refund it with no quibbles.
