Philip, noted thanks. That's good to know.
When we lived in Weymouth many years ago, I think we were the only people in the neighbourhood who did _not_ have some sort of a boat!
I've always regretted that
I made up for it though by doing quite a bit of fishing in the then Portland Naval Base/docks and off Chesil Beach. Good times.
I'm still not sure if I can trust the dealer diagnosis "Battery worn out" (a very technical expression, not.)
I'm monitoring it for the next few days before I get a second opinion and decide to replace it or not.

Philip, I've been to Halfords today.
This is it isn't it: https://www.halfordsautocentres.com/car-batteries/halfords--096agm-start-stop-agm-12v-car-battery-5-year-guarantee
Now £157 plus £25 fitting and disposal incl VAT, £182
No brainer really especially with it being a Yuasa and the 5 year guarantee.
It will be interesting to see if the VW/Varta made in Korea one can match that.
Thanks again for that tip.

Yes, that’s the one. I can’t testify to the longevity as I part exchanged the car three months later but I have seven Yuasa AGM batteries on my boat which are still holding full charge and output after two years of deep cycle discharge / charge so I have absolute confidence in the quality.
