Toyota tundra battery drain. Ive had the battery and alternator tested multiples times and both always test good. Battery was acting up. Mysterious battery drain.
I had a Compustar remote start installed on my 2002 Tundra that was killing a battery in 2 days. I have put my amp meter in series between the negative battery post and the negative cable and I measure 50mA with the truck off. I had it removed and no longer had battery drain issues.
If it seems high start pulling fuses to see what circuit is causing it. Battery is draining overnight not every night just sporadically. Does Toyota covers battery within 3 years.
After one hr drive tested it shows 450cca and the battery tester says replace battery. I cant see any reason for the draindischarge. Something is discharging the battery overnight.
Replace it with a new one. This will not workThe only way to chase down a drain is like said beforeUsing a amp meter in series with the positive battery cable. I was wondering if anyone else has had this issue.
Average failure mileage is 12550 miles. My 01 Exploder had the OEM battery for 6 years and at the end of that time it got just like you state. Most of the time its the battery itself causing this problem.
