There are 3 main brands 1. Battery Tender 2. Noco Genius 3.Ctek. They are good benchmarks for evaluating other brands.
If your car is idle for long periods it is important NOT to use a charger or float or trickle design. They tend to overcharge.
The new Maintainers do not overcharge and will also prevent sulphation. The sulphation causes premature death of the battery.
Worse, sulphation can cause a sudden failure when you try a hot restart. That will strand you.
So be very specific about what technology you buy.. I have all 3 brands mentioned above on some of my collector cars.Technical comparisons are hard to find but this may help:
I hope this helps

Just went to replace battery. Lexus wants $1,750 .00 for the battery. CRAZY PRICE. Cannot find any aftermarket batteries. Help

 

I just saw one at Autozone for $200. Maybe you are looking for the hybrid battery by mistake?

 

Just checked with dealer. REGULAR Battery is $1,700.00. Parts guy said it is a weird Battery and no aftermarket Batteries fit the specs of the car.

 

I just called Lexus dealorship in my area and asked about LC battery price.. He told me $300 for replacement battery. I mentioned the $1700 battery he said that

was for the original one in the car. The replacement battery is $300. Call another dealorship.

 

I usually try to stay ahead of the game when it comes to replacement parts. From my research it looks like a Group H6 or H7 (94R) battery will fit the LC. Prices range from about $150. to $200. Also, may I suggest an AGM battery. My experience with them is that they last far longer than a conventional flooded battery.

You can't go wrong with this one.
Product Search Results | OPTIMA Batteries

 

I put an Optima Yellow Top in my S2000 at the end of original battery life,
The Optima was great

Surprised to not see interstate or varta on that list

If you're gonna drop 1700$ on a battery might as well go lithium like the Pista

 

Any LC 500 owners use a battery tender/maintainer?
Is it safe to use one?

 

I've used a cheap Harbor Freight trickle charger with good results for months at a time on several vehicles.
