Helping out my FIL since his truck was dead as a doornail in his garage. Story is the battery died during a trip to the store, AAA came and replaced it with a new battery. Worked for a while, but he didn't drive it for a month. Wife tells me it won't start, so I load up my tools and find out it's not just weak, it's quite dead at 3 volts. Tried throwing the charger on it, but it seems to have lost a cell because it would not charge over 11.5 volts. Put a new battery in it, and the alternator is charging normally, but a quick check shows it pulls about 1 amp for 15 seconds after connecting the battery, then drops to 180 mA. That seems rather high, my Pilot just had a dead battery episode, and that pulls about 50 mA of idle current. Any idea what's normal for his truck? Can't find anything obvious like an interior light left on, but my math tells me that 180 mA for 30 days would be 129.6 amp-hours, way beyond a typical 80 amp-hour battery.
