EVs are still much cheaper to run than ICEs though. Yes the battery is an expensive replacement but maintenance is still much cheaper because they don’t have gearboxes, clutches, turbo chargers, catalytic converters, particulate filters, spark plugs, engine oil, timing belts, head gaskets, cylinders, exhausts, etc. etc.
Or get a normal mouse you can use while charging for 15 mins and then have a month of battery. Or charge for 2hrs while using and have six months of battery.
