Dead Battery
I got lazy over the winter and didn’t start the car enough. The car wouldn’t turn over at all. I connected it to a jumper pack to get it started. I let it idle for 30 minutes. I bought a Battery Tender the next day but it was too late. The battery is too dead to be saved. One dealership quoted me $250 and another $300. I’m doing it myself because I’m not being bothered with a tow there. It’s bad to drive modern cars on a weak battery and can damage other stuff. So the question is, should I go with an OEM battery (which I think is an interstate), or something else/better? Does it really even matter nowadays? It seems everything is so cheaply made.

I replaced the OEM battery with AntiGravity AG-H6-RS battery and did it in my own garage. Was fairly simple installation as long as you open the clips that are attached to the bracket holding the cables. One of the best purchases I have ever made, It reduces weight by 30 lbs (the 24 Ah version I bought), starts the car ridiculous fast, does not lose charge even after sitting for a few weeks, has an internal battery management system that prevents it from draining the battery completely so that the internal jump start feature could be used in case it is sitting for many months.
It costs more than the OEM battery, but it is totally worth it. Also, it is supposed to last twice as long as the conventional lead acid battery.

The RCF battery is a fairly uncommon H6R size. Nothing wrong with getting one from the dealership or seeing if your local Autozone has one in stock.
The Antigravity Lithium batteries are neat in that they include a reserve feature in order to jump start the car, but at $750 for a car battery, it's probably more feasible to just use a battery tender during long storage periods.

I just googled the Antigravity battery. Wow. That has to be the best battery that money can buy. Unfortunately I can’t afford it at the moment. I have to repair my 4 slightly curbed wheels (so pissed at myself), and must have Apple CarPlay added for $199 from the dealership this summer. But I’m seriously considering putting one in my daily next time because it eats batteries.

Go there and read. You'll have Apple car play in an hour... I did my wife's 18' NX a couple years ago and her friends NX. Apple Car play was a game changer for her vehicle but there is no way in hell I'd pay the dealer $200 to plug in a USB drive and go through a couple sequences to initiate the install...

The premium price AntiGravity charges is a lot due to being sold only through race oriented outlets as well as putting a very small battery into a mammoth H6 case so it fits where the AGM would fit. Went through this when I switched to a lithium battery in my motorcycle (also not used often). Yah, I did have to put spacers in the area to keep it stable (cut foam). But no need for a trickle charger (in fact, you would ruin the battery by hooking one up). I expect you would find an alternative if you looked around--but it'll likely still be more than a AGM since the lithium is close to "forever" with about 2000 charge/discharge cycles. Make sure it is deep cycle, 12v, at least 24 ah, with BMS (battery management system). You should know or find out the max voltage your alternator puts out since you can have too much charging current if the alternator voltage out is too high.

Thanks a million I appreciate it!. Lexus almost got me! All I need is an 8GB USB drive, I already have a windows laptop. I'll spend that $199 on better stuff. On a side note, after 5 days on the Battery Tender the green light started flashing. It's still severely damaged and needs replacing.

PLEASE do NOT pay the $199 for apple car play update. You can easily do this yourself for free.

Dealers around here charge an insane amount for an OEM battery so I replaced it with an Interstate battery.
I’ve been told the AntiGravitys are really nice but don’t last on cars that aren’t driven everyday.
I could buy 3 Interstates for the cost of 1 Antigravity.

Agreed, I had researched it a lot before purchasing my AG-H6-RS battery. They are supposed to last twice as long as traditional lead acid battery because they lose charge much more slowly than lead acid batteries over time. Also, due to an internal battery management system, the depletion is a lot slower as well.

Yeah I said it. LOL.

RCF replacement battery at Lexus dealership
My OEM battery on my 2015 RCF finally gave out and I had to get AAA to come by to jump start.
AAA got it started and tested the OEM battery and it is NO GOOD. I asked AAA if they had a battery in stock and they said NO.
I checked AutoZone and they have one HR6 in stock that costs $190 plus tax.
I called the local Lexus dealership and they have one for $170 (They said it is made by Interstate but they put on a "Lexus" label on it. It is an 84 months battery with free initial 2 year replacement and prorated thereafter to 84 months.) It was almost closing time for them so they could not install it for me. No worries as I am comfortable installing it myself and I did. Took me about an hour and all good. I took some pics and will share when I get a chance.
