2010 Focus Titanium - Disable alarm before removing battery

[plwsm]

Hi, My battery needs a charge but when I disconnect one of the battery ternminals, the alarm (siren) goes off. This car has the factory fitted Cat 1 alarm with backup battery in the siren. Is there any way to stop this? I tried locking/unlocking the car with the key, but this doesn't help.

Also, there doesn't seem to be enough space to get the battery out. Do you need to remove the bulkhead cover (and the windscreen wipers to get this off) to remove the battery?

Thanks

Phil

Front and one side of the battery box comes off to let you draw the battery out.

Have you tried putting the key in the ignition while disconnecting the battery?

Thanks for the help.

Putting the key in the ignition did the trick. The car has keyless entry stop/start so I had to remove the key cover to do this.

I could not find a way to remove the front of the battery box case as it seems there is a harness attached to it. This looks like it is screwed to the case and is too low down to remove without removing the air filter box. I did manage to unclip it and pull it away from the battery by just enough to get the battery out (the battery was almost on its end).

Thanks again everyone.
