I plug in the Battery Tender anytime I think it'll be awhile before I take it out again. It's really a simple task. The above picture of the battery hookup shows where the battery tender hooks together. I routed mine to the near the wipers on the passenger side. I don't even open the hood to plug it in. One thing I did and recommend if you do that is to put a sign on the driver's window advising you it's plugged in. It hasn't happened but could happen if I drive out of the garage with it hooked up...YOU DON'T WANT TO DO THAT! LOL I noticed they've gone up in price since I bought mine. 29.95 now 59.95? Wow! I've had at least one SC since 2006 and bought the tender then per Club Lexus advise.

Here are a few dumb questions for you guys
1- one member said” manually locking the two
doors “ help without the key fob. How does this help?
2- if you do park outside, seems like a bad idea
as the alarm will not be armed . I happen to park in the garage
and this idea just just seem crazy to get around the drain
3- if you are traveling and you are at the airport
or away on vacation with the car without electricty for the battery tender
, does everyone have to disconnect the battery each time
or resort to a jump for a drained battery
4- the battery drain seems like a bad design in the SC
5 - This is the first time my SC drained and went dead in 1/12 year
of ownership and with my other SC, this never happen but then
again I only put about 1,500 miles on this SC in a year
6- final question, do you guys just leave the battery tender on
plugged in 7/24 as soon as you park your car
arggh .. the life of owing an SC

2. I also park in a garage so I just close door without turn the alarm on. It helps.
3. You might want to do that if your battery is old, I was on vacation in January and left the car for three weeks without battery tender, no problem starting the car.
4. Yup.
5. I do 2K a year. I used to have the battery drained problem, until I bough new Costco battery and battery tender. Everything is ok now.
6. You might want to do so. I don’t think it will hurt the battery, since it trickle charge.

As a long term rv’er with a large diesel coach batteries are the key part in the coach.
all batteries need to be charged at a voltage that is adjusted by the actual battery temps.
if you want the car battery to have a much longer life a Battery Temp Management System charger would be my choice.
A hot storage area needs a much lower charging voltage.
not sure if anyone makes a temp controlled trickl Charger?
I installed AGM batteries in my three intermittent use vechiles to lessen the temp controlled charger needs.

I would get a new battery if this is the first time you have had the problem. Or check the trunk light issue. It is possible, the trunk wasn't closed all the way and the lights drained your battery.
In Arizona it is Hot and Dry so we figure batteries only last two years on average. Some people in AZ pre-emptivley swap them out, since you have to replace them eventually no matter what. Better to replace them on your schedule than to be stranded in the heat of summer.
All that to say, if your battery is older, swap it out before you buy a tender

No, it will nốt lock your car if you just turn off the engine, remove the key and slam the door.
Oh, I got you, you meant lock it with the key only. I think the alarm will aim, look at the blinking red light.

if I liven in Az a AGM battery would be my choice. If a optima red top is available it’s spiral wound design should help in the heat.
The two together would give the best long term results IMO.
This thread got me to order a battery tender plus for my garage stored sc...
seems Kalifornia says the plus is not energy approved. What a crock

Ahhhhh. That's the confusion. When I say to lock your car, I mean to manually push the lock down on the door. Not using the switch at all. Not the lock switch, door switch or key fob.

Hey Dshng
I actually had the car for 1 1/2 year .
The battery was new and I put in a new
battery from Lexus as soon as I bought the car.
This battery drain issue never happened until recently
but agsin I guess I haven’t really driven my 02 too much
about average 120 miles a month
My trunk was closed and maybe somehow the trunk light stayed on . Might just take the lights out as another option
I previously owned an 04, 03 and a 06.
The 02 I think has a bit more 1st year quacks
I know about the VSC light and the zero cabiration
and the negative camber issue with the tires.
Now I know about the battery drain issue ...

Replacing the trunk, map and door lights with LEDs will reduce the power drain considerably and help prevent those problems, if that is what is going on.

I have an 04 that I have had for two years...never had the battery go dead (and it sits in my garage almost all winter) and have not replaced the battery since I have had the car. Have read about this "battery drain" phenom several times on this forum...it seems that some cars have the problem and some do not. Have not seen anyone yet explain why this is or what causes it to exist in some cars but not others. Good luck.

Guys
hmmm , my battery is only 1 1/2 year old
and before , I never had the problem.
now I don’t drive much these days
about 125 miles a month though
and not sure if The battery after less
than 2 years will go bad
lexus dealer checked the battery and it
was within specs as well
a battery tender is now on the car
