effect of 1,500 low mileage per year on battery life

What is your question?

I only drive about 1,500 mile a year, trips vary from 4 mile to 7 miles one way. What is the effect on the battery life. I get confusing information that it is not good for the battery, while others says mileage does not matter. Which is right? I am not interested in the miles per gallon. My thinking is that the maintenance is less for a Prius. Thinking about a 2nd generation Prius.

What makes this problem better or worse?

just need information, any 2nd generation Prius

How long has your 2004 Toyota Prius had this problem?
