I recently replaced my battery in my 97 Tauras and my mechanic said my old battery was not the right battery. After I drove off the "service engine lite went out". It had been on for a while and I did not know why.

A few questions in one. There are a number of different battery sizes used for automobiles. The selection of size will depend on the cranking amps needed by the starter and the space available for the battery. A list of standard sizes can be found in the supplied link. Electrically, all batteries provide 12V DC, and will be identical to the electronics in your car.
The reason your light went out has little to do with the battery. Your car has a computer which keeps a history of diagnotic fault codes. As an electronic part encounters a fault, the fault will be registered in the computer and the light in your dash will turn on. A dealer or mechanic can then read the fault codes and correct the problem. The odds are that at some point, you had a minor problem with your fuel injection controller or an engine sensor, and the problem was coded and recorded. When your idiot mechanic replaced your battery, power was cut to your computer and so the codes were lost. So you don't have the light any longer, and now the problem can't be diagnosed. But you probably still have a problem. If so, the light may come on again, by and by. My advice is to keep the battery and ditch the mechanic.

The light went out because the PCM got reset when the battery was replaced.
Batteries are sized by a group number. the only difference would be the other battery was a different group size. Not that it damaged anything. And the MIL light was on due to an emissions problem that either was corrected or corrected itself but emissions faults do not reset themselves.

step 1 the check engine light is coming back on.. all he did was reset it by disconnecting the battery... I do it to knock out lights...
He didn't say why it was wrong... But usually people put too low of a cold cranking amp rating for a battery in the car... yeah it's cheaper than the right CCA one, but you pay for it later...
That and there are many different battery sizes/styles and someone might have put the wrong one in the car also

next time your at walmart look at the battery section theres hundreds of battery applications. toyota is the same . why make it easy for the consumer. He might have meant it didnt have the correct cold cranking amps. meaning it didnt have enough power to start the car
