Battery: every capacity sold under that name. “…”: other versions exist whose capacity has not been recorded. Battery warranty: terms recorded for the UK, for the most recent cars. New pack: order of magnitude at a French main dealer, in euros, never a quote. Miles/kWh: official WLTP consumption. Charging: at home, per 100 miles, from the most frugal version on the cheapest tariff to the thirstiest in real-world use.
How to read this table
The biggest battery is not the best deal in itself. It costs more to replace, and on a used car it is the remaining warranty and the state of health that decide, not the original capacity.
One column can show several capacities: the model changed pack over the years, and the car you are looking at has only one. Each model’s page says which, version by version.
For one specific car, the checker gives the remaining warranty and the expected state of health from the date of first registration and the mileage.
