What's up everyone. I have an 02 es300. My problem is my battery keeps dieing. I've replaced the alternator. Since then I've replaced the battery 4 times. I replaced my starter just last week because I thought maybe that was the problem. It's not. Now when I boost it it goes pretty cool until I cut the air on. Then when I'm at a red light the battery light comes on. The dash starts flickering and the radio statics. Then when I go it stalls then pop right back on and drives. I'm so confused and I don't know what's up.

Your car's symptoms could be caused by to many things to accurately assist you. Take it to a professional.

I agree, if you are in the mode of throwing so many parts at it w/o diagnosing it properly, in the long term you will be better served with professional advice.

That said, if you just tossed in an alternator from a generic auto parts shop that was the lowest cost alternative, I'd check out that. Many alternators on the market these days are not properly rebuilt and there's no real guarantee a "new" one from a discount auto parts store is going to work. Personally, I'd investigate if your new alternator is actually working. This can be done simply with a cheap multimeter by someone with basic skills. And should have been done both before and immediately after the alternator replacement. From your post, I do not get the sense that either of those basic steps was done.

Everything you describe easily flows from this single point failure. We have an 02 ES and the alternator is a weak point. I rebuilt mine myself for a total cost of $26 for bearings and brushes and would not have trusted a rebuilt unit from O'Reillys or similar after researching this issue.

ugh... electrical...

take it to a mech, they'll charge you for going over everything...

You may just have a parasitic drain in the charging system somewhere which is causing your batteries to die...

Problem with this is, is that it takes time = $$ from a mechanic.

BUT, it can solve all your issues.

Try this. Shut every think off from inside the car. Open hood and remove the positive battery cable. Use a volt meter to see if there is a voltage draw how ever small. If there is you could have a shorted wire or something isn't turning off. In that case you can pull fuses till the volt draw drops to zero. Good luck.
