A word of caution . . .
If you’re contemplating doing your own battery replacements again, you might want to consider a memory saver
Not only will it preserve your radio and clock settings, it will also preserve your readiness monitors . . . an important detail, if the car will be due for smog inspection soon. It would suck to show up at the smog inspection place, only to get turned away, because the car’s not ready. That’s time wasted, in which you could be be doing better things
[/quote]In relatively new cars, I thought these were stored in nonvolatile memory so disconnecting the battery wouldn’t erase them. This is also why disconnecting the battery won’t clear error codes.
