The factory battery has given up the ghost after 7 years.  How easy a job is the replacement?

Simple mate.

Out with the old. In with the new

I had a choice to make between two brands, both listed as compatible. The type I got (somewhere in a thread here) was the same spec as the other but a better dimension for a fuss free fit.

Is it flat? ?.......... so reduced in size.

Should just slip out

Yeah, I found out the hard way not all are equal. The one I used is marginally smaller and does not clamp in hard as the old RACQ 4504 batt. Darn expensive these days too. I do have 720 CCA though

Yep, same here, nice crank power at that spec. I was just lucky to have picked the right one where the shop had the better fitting type and could advise.

I got a Bosch one with a 5 year warranty for £66 from Costco.

The clamp bolt is rather inacessible for my socket wrench so going to have to go in with a spanner.

seems a good price.

correct amp output?

Hope so haha.  It was the one listed in Costco's book as being for my car, and has the same EU battery model on it (540?).  It was very slightly taller than the factory battery but fits nicely enough.  No protruding lower edge on it though.

Pretty sure this is it: Bosch S4 Car Battery Type 005 / 056: Amazon.co.uk: Car & Motorbike

Bosch S4 024, 540CCA.  Okay it's not 720CCA but it's what was listed for my vehicle.

OEM hyundai battery was a bit odd size. I cut the other side off from the battery holder and fitted slightly larger "normal" size battery.

One of mine was 600cca. I figure the larger the capacity the longer it should last. I had my old one tested it was 600cca and tested 440cca. Probably ok for a petrol still
