After 5 - 6 years you'd be lucky to get half a day and that's not using it all the time either. Obviously they'll have optimum charging etc but I'd be surprised if they only lose 10% over 10 years or it'll actually be much more.

I'm not aware of any advancements in tech that has improved the issue and I can't imagine a replacement battery coming along very cheap either - in fact I'd imagine it being borderline uneconomical. I'd be surprised if they get anywhere near 15 years out of them without major cost.

A battery in a motor vehicle is not comparable to that of your smart phone, despite them being made of the same material. Automotive batteries used in high end vehicles that are correctly heated and cooled to maintain an optimum operating temperature barely degrade at all.

Older cars with systems like these such as the Tesla Model S and BMW i3 still have well over 90% of their original capability, the original Nissan Leaf, which doesn't have battery conditioning is more comparable to an old iPhone however. I'm not an expert in what is used in buses, but if it's like that of Tesla or BMW, they'll be fine for their usual service life.

Even after, their batteries will hopefully continue to be used as storage in people's homes/businesses, as there's usually plenty of life left in them even after their automotive life is finished.
