Does the 80% Charging Rule Still Matter in the UK?

Get the Smart Buyer’s Guide to Used EVs in the UK: how to check battery health, dodge costly traps and secure the best deal before you hand over a penny. 👉 https://ev-insights-uk.pages.dev/ 0:00 Why the 80% rule is changing 1:16 The two different 80% rules 1:56 Nickel-based and LFP batteries 4:03 Battery health and high charge levels 5:55 Why LFP cars need regular full charges 8:11 Home charging and UK tariffs 10:30 Why rapid charging slows above 80% 17:03 The practical charging rules for UK EVs The 80% EV charging rule is not as simple as it sounds. I explain when it protects battery health, when it wastes time and money, and why the right answer depends on the battery chemistry and charging location. I compare nickel-based batteries with LFP, including how NMC, NCA and LFP packs behave, why some cars should regularly charge to 100%, and how to identify the chemistry in a specific model. I also cover home charging, UK energy tariffs, rapid-charging costs, motorway journeys, winter range, preconditioning and the practical charging habits that make the biggest difference to electric car ownership in Britain.
