That's right, you need to tell theircomputer there is a new battery.
I'm not sure if other makes are goingthis way, but it is one item on the lo=

Thanks to all who added to my knowledge basefor modern cars and batteries.
I replaced the old battery the next morning,started right up, and continues=
to run perfectly. =C2=A0I guess I'll justhave to have battery tested after=
about three years of use.
Thanks again!!
