Is 300ma too much drain while the car is off?
Lately I've been having issues starting up the car during the morning, requiring 3 cranks and during the evening with 2 cranks. I am on E85 with modified cranking values. My car is 2.5 years old as well. Also a manual transmission with the measly 390CCA battery lol. Mornings here in CA is now in the 50's F.
Last week, I tested the voltage over night with the battery still connected to the car at 12.7V after an hour's drive, and then in the morning it was at 11.9V which is almost empty.
last night, I took the battery out of the car after an hour's drive and tested it at 12.65V, then tested it again the next day and it was 12.5V. Compared to a new Bosch battery I bought, it tested at 12.7V and stated at 12.65V the next day.
So seeing how the stock battery is still holding its charge somewhat, I plugged it back in and tested the amp draw with the car off. It tested at 330ma which seems high according to some sites that says 50ma should be the limit, but another site said 300-400ma can be common for today's cars with all the electronics.
It's a bit late for me to test pulling fuses to see where the draw maybe coming from, but I was curious if anyone else has encountered something like this.
EDIT: so it's been bugging me, i went ahead and pulled some fuses but unfortunately none of the big ones were the culprit:
horn (recent switch to PIAA horns)
headlights (using Diode Dynamic Always On module but disconnected to test)
radio (added backup camera but disconnected it to test)
