Hi all

I own a 2008 Ford Focus Zetec 1.6 Petrol. Couple of days ago the battery on it went flat. I called up roadside assistance (AA) for a jump start (and to establish the reason behind battery dying all of a sudden)

Using a jump starter to the battery the car was started and the engine left running for good 10-15 min. however the moment the battery charger was removed the car died......

The multimeter gave him the following readings

VOLTS - 11.29V

MEASURED - 62 EN (A)

RATING - 390 EN (A)

I am assuming the battery is done for good and needs replacing. Is this assumption correct? But that doesnt explain battery draining all of a sudden.

I am not sure of the part number of the battery since i cant see the full text on it (due to clamps) but attached picture shows the part number to be

6G9N-10655-LA

Is this the right part number? I tried searching for a new battery using this and could not find ANY online. I was told that its a type 079 battery (but this type doesnt appear anywhere)

I intend to buy a 12V Silver Calcium Varta or Exide with a CCA of around 600, however i just cant seem to find any which correspond to the FORD battery part number i have.

Any one had to buy a replacement for their ford focus? Any suggesstions/recommendations on the battery?

Also how do i make sure that the problem is the dead battery and not anything else (like battery draining power due to any wrong wiring etc)

any help is hugely appreciated

6G9N-10655-LA is a Ford part number. This is a 43Ah Silver Calcium battery with 390 CCA.

Most aftermarket battery manufacturers do not refer to the Ford part number. They just list the specifications of the battery.

You should search for a battery with the correct dimensions and location of the connections (these are reversed on some types of battery).

thanks for your reply. just had a quote from my local ford dealer quoting me £148 inc VAT for a 590 CCA ford battery fitting included. it is costilier than buying one and getting it fitted separately but i am tempted to go with it just to get it done with.

how do i find an alternative for this ford battery ? i tried searching and this gives me a list of substitutes http://www.findpart.org/part/for-6g9n10655la/ but again when i go and look at one of the substitutes http://www.findpart.org/part/var-5444020443132/ this doesnt have ford focus 2008 in the list of cars (which this battery will fit in) so i am confused.

thanks for your reply. extremely helpful

with higher CCAs. Only question i have is that the one you suggested in the hyperlink (the Bosch one) is a type 027 and these i have chosen are 075. how do i make sure which one is the right type. they have slightly different dimensions.

i used the parts filter on europarts and it came up with these options.

On the euro car parts website, I just put in Focus 2008 1.6 petrol, if you've put your reg number in then go with one of those you've listed. Can you measure your battery in situ? just to make sure one of those fits.
