My IS350 needs a new batterery and I was wondering if anyone has an Optima Red Top. I have used them in the bast and really like them. Are they a direct drop in replacement or are any modifications required?

Seems like a minor thing to make the red-top battery fit:

Another option for you.

I just recently replaced the battery a few days ago. OEM battery size (with the cover) is group 24. Anything else won't fit perfectly. After reading several posts here and other places, I decided to go with less expensive route on a duralast gold 24-dlg at autozone. Search online for a 20 off coupon if you use the reward card (can join on the spot). The OEM battery is slightly shorter than group 24 (meaning any group 24 battery will be slightly higher) so I had to cut off the part of cover where meets the clamp. Paid $92 + tax for the duralast gold.

And another FYI, after reconnect the battery, you need to reset the windows by moving the windows up and down using its own switch on the 3 non-driver side windows. Afterward, you can control all 4 doors on the driver side.

^^^^Not really. But, even if they were, they do not have the Group 24 size. I believe they try to jam a Group 35 or some such thing.

I have had an optima yellow top in my truck since 10/2006. it was $200 at the time. (not sure how much they go for now) but it has been well worth the price. I tested it on my last oil change and it measured 748/750 CCA. Still going strong.

Thanks all. The Optima Red top is about $145 shipped online but about 200 +tax locally so I want to make sure it fits before I order it online. Sound like it will though. I think it might be worth the extra 45 in the long run compared to the normal battery.

It might be cheaper online, but check how you would have to handle the situation if you need to exchange the battery under warranty. Chances are, you will probably have to pay for return shipping back to the online retailer (or maybe Optima itself). Shipping on a car battery will not be cheap if you have to exchange it. Plus, you would have to get a replacement battery while you send the faulty one in if you wanted to drive the car in the mean time as well.

It may be worth it to just get it from a local retailer where you can exchange it at the store locally if anything goes wrong with it.
