I just had a quick look at the battery you mention @Oscarmax and from what I have read it sounds good. Ticks all the boxes for latest standards ECT. I am sure you would be fine with his battery.
I have no idea on costs comparisons though. Having said that, just looked and wow!
Do you have someone to install for you ?
