The batteries will degrade to some extent. Some of the better leccy cars(except the leaf) have liquid cooling which helps make them last longer.
The Prius is still for me the smarter choice but they're a little too pricey even secondhand.
14k for a 142D Prius over 5 years is 2700 a year plus 2/3k per annum for juice versus a newer leccy car that will cost 20/25k to buy new.That could potentially last 7/8 and maybe more years with the small mileage I cover.It has disadvantages but the grants are starting to bridge the gap.
The KIA E niro has a 300mile range so even if it lost 20% range towards the end of ownership you could still cover a shift was without having to go home early.They're hard to get but next year there will be loads on the road.
A Kia? Dont tink I'd trust that brand
Leaf is Good on range now but theres a parts issue and lots are been stolen I hear just rowed away and battery disconnected so the inbuilt tracker is off
Gonna look at a jap import Prius for my next car
All the Indians and Pakistanis have them and they watch the Penny's
Diesel is finished soon
Saw a hybrid Corolla looked good dont know if it up to nta spec though
