Hi, i think my battery may be on its last legs. Last night i got in and left the interior light on for about 20 min's, I soon noticed and turned it off and thought nothing of it. Got in it this morning for work and it was dead! Also a couple of months back, i accidentally left the headlights on for literally 2 min's whilst i got money out, when I get in the car it was dead again!! I understand the headlights use a lot of power but 20 min's of the interior light....surely not!!!?
Do you think i should replace the battery, I'm guessing its about 2 years old now. I had a new alternator fitted last year as well.
