370 RPM and Car is abnormal after changing battery
Hi
I had to change my dead battery for a new one so I bought a new one that makes out 72 Amps . It is electronic one and it is called EXIDE
After installing, I pushed the button and the car started for a sec and then shut itself !. On second attempt car started and the AC wouldn't turn ON .
On the third attempt and until now the car would start But there is something wrong
1- when starting in the morning it doesn't make a Cold Start, the RPM won't go up.
2 When stationary the RPM stays on 370 RPM !!! it feels that the car will shut itself
3 Windows are so slow now
4- When stationary the AC compressor Won't operate because of the low RPM , I have to push the throttle to get to +500 RPM . And once I release my foot it would go off immediately .
The new battery voltage is 13 volt when the engine is off
The car had non of the issues 5 minutes before installing , and there are no error codes now.
So what do you think is the cause ?

Have you rebooted the windows properly? You need to do this if you disconnect the battery. They will not work properly until you do this.
Open each window fully, hold the switch down for one second at full open. Then close the windows, and hold the switch for 1 second after window has fully closed. Do this for each window.
Any chance that you disturbed a vacuum line? A disconnected vacuum line will make the car run very badly at idle.
Also, the first non-start is normal. When you put on a new battery, the car will not start the first time. It will just crank and then die.

PROBLEM SOLVED !
Thanks for participation.
Apperantly the ECU were reset and the car had to re-learn to the new changes .
about 30 hours after replacing,all the problems are suddenly gone when I started the car in the evenining.
The windows needed to be programmed by pushing each button 5 seconds down and then 5 seconds up ! It is a procedure that should be done each time a Lexus battery is changed.
I had a battery change one year ago and these problems didn't occur though .... So you might face them you might not.
Better to leave this info for others
thank you

I know the problem is solved, but I just thought I'd share this since I learned it from the guy who changed my battery (I used AAA Battery Service). To reset the ECU, he started the car, ran it to 2500-3000 rpm for 30 seconds, turned it off immediately, and then restarted. Back to normal immediately! Despite being a classic car guy, this guy even knew how to reset the windows, which really surprised me.
