Just had to replace my battery because it was done. I noticed that my old one that dealer must of put in was a Duralast 500 cca. The Everlast i bought was 550cca and IDK if its in my head but the car seems to start up better n run a little smoother. I didnt think the battery had anything to with those topics, could I be wrong or is it something with our cars?

 

It may start better yes. But the car doesn't run on battery. Once the car starts, the alternator takes over.

 

+1 but a loss of battery can cause the engine to fail.. Found out the hardway in DT charlotte. Glad you got your problem fixed tho!

 

They reset your ECU.

 

Came in to post and ^^^ BINGO!

haha yeah, beat me to it as well.

 

Isn't the ecu reset anyway after the battery is disconnected?

 

me too it died at the worst time too! lol ..what could reseting the ECU have to do with it running smoother cause i definatly have noticed it idleing a bit smoother..

 

^The ECU adjusts to the way you drive. Most people drive their cars normally for the majority of the time its running so that is what the car "remembered" and adjusted accordingly. If your at WOT all the time the car would drive differently. Reseting the ECU clears its memory which allows the car to perform slightly better.
Yes, which is how it reset.
