Battery drain as weather turns warm

Asked by NSRN116 Apr 14, 2019 at 01:16 PM about the 2007 Honda Accord LX

Question type: Maintenance & Repair

My 2007 Accord worked fine through out winter, as warm weather comes the battery died on me several times. I replaced the old battery, the new battery died again after only driving 30yds away at a gas station. Then I went back to the store, both batteries the old and new are checked, both are good. I noticed the radiator cooling fan was on whenever I turned key on without starting the engine, while I sense the radiator temp with my hand, it was only warm. So the fan turns on unnecessarily, draining the battery I assume. The car worked without issue during Michigan winter, because it was so cold, the fan never turned on. So my hunch is that the thermal sensor is bad, yet the dashboard shows the temp gauge didn't go crazy high. So I still try to figure out what went wrong. Thanks for your help.

I believe the fan sensor is different from the one that serves the gauge.

Thanks F_O_R! So the culprit is the coolant temperature sensor. I only wonder even if the fan is on all the time while driving, would it drain out a battery like that? During hot summer days, the fan does turn on most of the time, but won't drain out the battery though. That's what makes me puzzled.
