Gotta a question here,The battery in my wife's 09 petered out 3 months ago&Took it out.
Getting ready to put a new 1 in,Would there be any averse effects on the ecm&or computer from sitting so long without power?
Besides resetting the radio?

 

There shouldn't be any problems. We have seen in the past with the keyless entry loosing memory but it was not related to how long the battery was disconnected.

 

Thanks Lucky,Didn't plan on it sittin without power for so long,Since new I like to start it at least once a week&run it through the driveway during the winter.(Gears&Brakes loosend up)Normal driving during the Spring/Summer/Fall
These things got enough problems without having to deal with the good old Ohio roadsalts

 

Gotta love Ohio's salt belt
