Degradation, warranty, winter range and highway efficiency.

Real-world data shows most EV batteries lose capacity slowly. What degradation looks like, what the warranty covers, and how to slow it down.

Cold weather and motorway speeds are the two biggest range eaters. Realistic loss figures and the habits that win the range back.

Modern EV batteries lose capacity through a mix of cycle ageing and calendar ageing, but daily habits can keep degradation to the fleet average of 1-2 percent p

Most electric vehicle batteries in the UK come with a warranty of eight years or 100,000 miles, whichever comes first, and the manufacturer will usually repair

Electric vehicle efficiency, measured in miles per kWh, reveals far more about real-world running costs than headline range figures alone. A family hatchback ac

Electric vehicle batteries rarely fail completely. Most packs in the UK retain between 70 and 80 percent of their original capacity after 100,000 to 150,000 mil
