What is the optimal charging time for a Nissan Leaf in colder climates?

I live in a colder climate and I'm wondering how long I should charge my Nissan Leaf for optimal battery health and performance. I've heard conflicting opinions and I want to make sure I'm not damaging my battery in the long run.

In colder climates, it is recommended to charge your Nissan Leaf for at least 8 hours to ensure a full charge and maintain battery health.

I've found that charging for 10-12 hours overnight works best for me, especially during the winter months.

I live in a colder climate as well and I've been charging for 10 hours during the day and have had no issues with my battery.
