The quote you reference doesn't make a distinction either way.

Doesn't it? It says:

> That usually means that if your battery is below 70% health within either 8 years or 100,000 miles, they’ll replace it for you.

Consider a car with 200k miles at 5 years. 5 years is within 8 years, so I don't see any way of reading "within either 8 years or 100k miles" that would not make that car covered. Similar for a car that is 15 years old with 50k miles.

But everything I've seen elsewhere says the warranty applies as long as you are within 8 years and within 100k miles.

Well played Sir.

My MG4 (Saic) has a five year warranty and rather a lot of small print, that I should probably OCR and pass through Chat for a summary and then read myself.

I do know it will last longer than my last car - a Ford Focus with an Eco boost abomination of an engine. The engine oil warning gauge thing decided to only kick in at just above the bottom level on the dipstick. Even so all should have been fine. I even drained and replaced the lot. This was a three year old car. It degraded over about a month and eventually passed away in Bristol. I live in Yeovil, a good hour away.

My first car was an elderly Mk1 Ford Fiesta (it was old in 1994). That often managed to run without any oil for some time because it had ended up as a rusty stain with the contents of the radiator on the underside of the bonnet (hood) and on the road.
