I have a 4.5 -year-old bosh battery that the previous owner got installed by a Euroshop. Two weeks ago the battery totally died on me (JUL 18). I took the battery to Advanced Auto, had them hook it up to a charger and battery condition reporter. It was showing my battery was at 165 CCA (rated 720CCA). They kept the battery on the charger overnight and called me the next day and said the battery is fine (charged to 820CCA) it just needed to be charged. Two weeks pass by and the battery is dead, once again. I kept it on a trickle charger for 2-3 days after the battery was fully charged by advanced auto. Drove it the next week twice 140 round trip. Is it time for a new battery? Or can something be draining the battery? I keep the car locked in the garage.
