3 dead batteries in 2 years
My 2013 GS 350 F Sport has had three dead batteries in 2 years. So dead, that they couldn't hold a charge. This, along with a 4 page long service history, and the car having more rattles than my 2006 4runner is why I'm considering moving onto a BMW

My 2014 F Sport also wouldn't start on Christmas Day. I ended up calling AAA and went ahead and had the battery replaced. I looked at the original Panasonic battery and it was rated at 580CCA. The battery when tested only went to 300CCA. It was replaced by an Interstate 700CCA battery. Hopefully this solves the starting problems. Considering on moving to an 800CCA AGM Interstate Battery if this battery doesn't last. At least the warranty is 3 years free replacement and 3 years pro rated after.

Replaced at 33,000
Started clicking instead of starting right away, did eventually turn over all three times it didn't start first try
Got an appt, test came back bad battery. The tech mentioned he's seen a few with bad modules or something draining the battery overnight, and killing it, so they ran a full electrical test which came back clean
Replaced old Panasonic with Interstate version...
Under warranty, $0

Has anyone removed fuses with a meter hooked up to their battery to see if they could tell where the drain was coming from. My car has a 20 milliamp drain, not real high. When I checked it in January; that figure did not change whether the alarm was activated or not. Not a Lexus
If my math is correct (which is saying a lot for me) I figured that a 18 milliamp drain on a 40 amp nominal capacity battery (10 hour rate-amp hour) would lose 1 amp/hour of capacity in 55.5 hours or 20 amp hours in 46 days, i.e., 6 weeks. So that would mean the battery would have lost 50% of its capacity.
Try an Oddest battery; they are sealed, and can take a lot are deep cycle so if they drain down they can be recharged to full charge with no damage to battery.
They are used on small airplanes and they are probably one of the best made.
