Fairlady z battery change

[Fletch350]

Having gone through a few posts on search....I'm changing the battery on my 2004 fairlady.

Car has UK battery posts and I'm going for a Bosch s4,the procedure as I understand it is doors unlocked and windows down.replace battery and close windows holding buttons for 3 seconds to reset? 

The car has a sterling alarm/immobiliser if that has any bearing? Any advice welcome.

I changed the battery in my 08 hr...same bosch s4 as you...the procedure was disconnect old battery, fit new one, job done:-)

Same as above for me too. Old naff one off, new overkill one on.  Only tricky bit was getting the new large battery in the small space and refitting the retainers.
