Hi, after some advice regarding battery size on my 1.4 ecotsi 150 with start/stop. Most websites list the correct size as 027 59ah but Tayna lists 096 70ah. Currently the car has a Lion Calcium 096 70ah. So what’s the actual correct spec and if I do end up buying the 027 will that mess with any of the car’s electrics as I’ll be downsizing? Thanks in advance
