I have a 1997 MX6 2.5i V6 that I purchased a new battery for a few month back.
This battery is 480CCA 60Ah and it really struggles to turn the engine over.
I have been told by a local Mazda dealer that it is the wrong battery and it should be 570CCA 70Ah but this isn't listed on the battery sites I've been looking on.

So does any one know what the correct battery is for it?

I've had the alternator tested and that is fine so this can be ruled out.

Any help would be much appreciated.

 

My local century website( Australia) say's a 2.5 MX-6 needs a 55D23L, which is 540CCA.

However, a 480cca battery should work well. You need to get the current draw measured/cheked when cranking. You starter may be dying, or you may have high resistance in the starter motor wiring

 

Thanks for the reply,

The garage I use have checked the current draw on crank, battery to alternator and they say the alternator is pushing out what it should, not had the starter motor checked yet.

The local Mazda dealer have said the battery should be 570CCA 70Ah.

The battery that is on the car at the moment is just not turning the engine over fast enough to start it straight away.

 

The alternator has nothing to do with starting the car.

The starter motor starts the car, that's what needs testing.

 

The alternator was tested to make sure it was pushing the right current to the battery which it is.
Next on the list is the starter motor, once the garage get back to me.

 

New battery fitted and that seems to have sorted out the problem. New battery is a Varta 630cca 70Ah
