What is the best way to maintain the battery life of a Nissan Leaf?

I recently purchased a Nissan Leaf and want to make sure I am taking the proper steps to maintain the battery life. What are some important things I should keep in mind to ensure my battery lasts as long as possible?

Regularly plug your car in to keep the battery charged, especially overnight to take advantage of off-peak electricity rates. This will help preserve the overall health of the battery.
