[question]
Does DC fast charging reduce battery capacity?
[/question]
[answer]
Frequent, high-power DC charging can accelerate cell aging (mainly due to thermal stress and chemical strain). Use it when traveling or when needed, but for everyday use, home AC charging is gentler.

[question]
Does AC charging “preserve” capacity?
[/question]
[answer]
AC's moderate power and thermal load are more favorable for battery health, so over the long term you can expect slower capacity loss than if you typically charged with DC.

[question]
What “battery hygiene” is recommended?
[/question]
[answer]
Mostly cycling between 20–80%, charging to 100% only before a longer trip; avoiding extreme cold/heat, pre-conditioning the car (if it supports it), and using temperature-friendly charging modes.
[/answer]
