I changed the oil and filter yesterday and while under the hood, noticed + battery post was a little corroded. I cleaned it and reattached wire to post now it won't start.
All electrical was functioning at first--radio, key in ignition reminder, dash
lights, etc. After about the 10th try and reaffirming battery cables were on
tight, electrical stuff started not working and it wouldn't even click when
trying to turn over. The battery is dated 12/2014. Is it safe to assume that
the battery pooped out finally or is there potentially something else going
on that happened when i disco'd the battery?
