Battery works great and will outlast our ownership so it will stay where it is and will be fine. It had a 35 in it from the PO and it was only a year old and was a advanced auto parts brand. They would not take it back cause it still held 450 ca out of the 650 it was rated for. You could park the car 3 days and the battery would be dead. Did a parasitic draw test on the car and it was within spec. Put in the new battery and it has been great ever since. It actually seems to be running much better as well.

Update: put in the 27F.

850 CA 700CCA, exact same as the 24F I replaced it with.

27F fits like a glove, no noticeable size difference between it and a 24F

Width is different.

Awesome!
Did you get the 27F from Costco for $85? If so, how is the warranty?

KC98LS

Appears to be exactly the same as my 24F. Any difference in minuscule.

Sure did, Interstate brand with 3 year warranty, and additional pro rate.

Sorry about image quality but here's a 27F and a 24F right off our shelf...

That's strange, my 24 and 27 were almost identical in size. Would take a picture, but already gave old 24 back for core charge.

Maybe my 27 is a 24?

I used to work in a battery store when I was younger. The 24F in our 92 was not as wide as a 27 for sure. Check for a sticker on the side of the battery. You'll have a letter followed by a number. The letter will give the month and the number will be the last digit of the year. That will tell you the made date. The other sticker will tell you the group number.

no way a 24 is the same size!

As others have already showed, 24F is correct size for a 1998 LS400. I installed a 24F purchased from Lexus last year for my 1996 LS400. Not much different in price than direct from Interstate Battery. This battery size is sufficient for the coldest starts here in MN. Batteries only last about 6 years at most. The battery will last longer if you use the original plastic cover/insulator. It is designed to force intake air over the battery to keep it cool and prolong life.

Just get an optima and call it a day. Too tall? Cut holes in the hood. Duh...

Hard to believe people with 45 thousand cars are looking to save 100 for a battery that lasts 5 years....Just buy a fiat.......a quarter waiting on a nickel....

Are any of the Lexi on this 1st and 2nd gen list $45k cars? $25k? Do I hear a $5k? My '91 is awesome, but I doubt I could sell it for $5k.

And we're talking about a battery. Not quite as fungible as gasoline or oil, but close. Props to the OP for ignoring some advice, figuring it out, and letting us know - thanks.

BTW, in addition to optimizing price/warranty/size/specs/fit, one thing I try to do with batteries is to find ones that will fit interchangeably between my cars when possible. Many times electrical / battery-related problems are intermittent / weird / difficult to diagnose. I've found that just swapping batteries between cars to see if the problems stop or move is a good and very easy debugging step.
