This is about my Nissan Altima 2.5S. I drive it to work and drive back to home every weekday. My workplace is 10 miles from my home and it's about 20 minutes' ride single trip. Other than that the car is not driven much.
I got the car in February 2010 and my driving pattern has been the same in the past 3.5 years. The battery was all good until last winter when it started to not jumpstart after not being used over the weekend. I took it to Nissan service for checkup and they told me there was nothing wrong with the battery or the alternator, it's just not driven enough to charge the battery.
So I ran some long errand (>2 hours trip), after which the battery felt like rejuvenated for 2 weeks, but as soon as I do not go on long errands, it dies over the weekend. I called the service department again and their response was the same, that I should drive it more.
So my question are:
- Is my usage really below the minimum requirement to maintain the battery?
- Should I take my car to a different place to checkup?
- Should I get a battery charger/tender and use it for every weekend?
