OWNER ANSWER
Should I charge my BYD to 100%?
Yes—BYD UK says you can charge its electric cars to 100% and use DC rapid charging. Plan around the range you need and follow the battery-care instructions in the handbook for your exact car.
- Open the battery-care section for your exact model and edition. For example, original SEAL RHD EN-250305 recommends a full charge at least weekly and a full charge from below 10% every three to six months; this example is not an instruction for every BYD generation.
- Choose the charge you need for the next journey. Safety note: If a plug is damaged, unusually hot, smells burnt or shows smoke or arcing, stop using it and keep clear. Repeated electrical trips need the installer; reconnecting can worsen an electrical fault.
- For that original-SEAL periodic low-to-full charge, plan around normal battery use and access to charging; do not strand the car or run it to zero. A later car or different model needs its own handbook interval.
- Allow more time for the final part if charging to full.
- If charging stops unexpectedly, check the selected car, charger or tariff target before treating it as a battery problem.
What to expect
The selected charge meets your journey needs and the battery-care guidance for your exact handbook. A full-charge session finishes normally; a paused schedule or reached target is different from a charging fault.
If that did not work
If your car repeatedly refuses a requested charge or shows a fault, ask the operator about the termination reason and BYD about the vehicle warning.
For the original SEAL, the handbook also recommends a full charge after a long idle period because the displayed percentage may be inaccurate. If the percentage continues to jump abnormally afterwards, ask BYD to inspect it; repeated deep discharge is not a diagnostic repair.
A normal full charge or a fault?
A session reaching its selected target is different from an interruption with a warning. Another brand’s everyday charging rule is not a substitute for your BYD’s battery-care instructions.
