My RCF does not sit as it is my dd. Tried to start this AM and get rapid clicking sound. Step out of car and all lights are flashing and have a clicking noise. Disconnected negative post on battery and clicking/flashing lights stopped. It's a 2019, could battery be bad so soon?

 

Been through that myself with my OEM battery I replaced last year. The rapid clicking sound and flashing lights etc. are a sign that the battery is on its way out. You could use a jump starter (portable one) to get some more life out of it, but it will have to be replaced. The OEM Panasonic batteries don't last very long. You might have to look into buying a new battery. I bought an Antigravity lightweight 12 lbs Lithium Ion battery with its own internal battery management system. Now, even after the car sits for a long time, it still spins ridiculously fast every single time. It also has its own internal jump start feature (comes with two fobs).

 

The only thing different from normal. I left my key in the car for a few days. I can't imagine that to be an issue (key and car trying to communicate, lol), but just throwing it out there.

 

Batteries die every 3 years like clockwork here in FL, I don't think a 2019 needing replacement is unusual.
Might not have been the best example from the factory and died a bit earlier than the norm.

 

Experienced the same thing on the IS350. I assumed the battery is about to die. It did come back I've after I charged it overnight with a battery charger and worked fine since.
We'll see how long it lasts...

 

I have a 2019 too. My battery went dead from sitting. My lights went crazy too it was kind of cool. Replaced the battery, everything’s back to normal.

 

That can absolutely be an issue. Generally it drains the key battery fast though. I saw a TSB for my wife's Armada where leaving the key too close (like on a hook on the door going to the garage) would cause the battery to drain and trigger the welcome lighting to keep coming on. Basically just keep trying to communicate and "waking up" the car.

 

~36mo and right after some cold weather?

cca testers are super cheap on amazon, doesnt' hurt to have one around


that tests your battery everytime you crank it and logs it for you, easy as hell to install

 

Car is garage kept and temps don't get too low in VA. Put a slow charge on the battery and it starts right up now. I will probably replace the battery soon and be done with it.

Thanks all

 

Same exact symptoms as my car when the battery died. Replace it before you get stuck somewhere.

 

I actually use this whenever I dont drive the car more than a week (life of working from home...):

 

My battery recently got drained as well. Not sure how old it is, but I'm pretty sure it was because of a USB charger thing I recently installed. It's one of those with the battery voltage display. It's supposed to have minimal battery drain but apparently not, as about a month after I started using it the car started to gradually take longer to start. I was off for a few days and it died completely. All the lights were flashing, the remote entry still worked. I jump started the car with a portable jump starter, an of course unplugged the USB charger. Since then it's been cranking up a bit faster each time I drove it, and today it's completely back to normal (on 4th start since it died, each drive ~6-7 miles to work). Interestingly until this afternoon, I was getting error messages "check PCS", "trac off", and the check engine light. After the car started at normal speed this afternoon, all those error messages went away.

I'm not sure how much longer the battery can last after this, so I'm definitely gonna consider a Li-ion battery. The Anti Gravity battery seems pretty good, but pretty expensive. Dakota Lithium has a 60Ah one for $600, but doesn't have the same features and only comes in group 24 size. Anyone knows how well the group 24 would fit? I wonder if there are things I can do to secure the battery.

 

My original 2015 RC F battery still lives on in my daily driver IS300, and so far hasn't shown any signs of weakness. I moved it there ~3-4 years ago when I got the braille battery. IS300 sits outside since I got the IS F ~2 years ago.

 

Typical behavior of a dead battery. Get it load tested, and replace as necessary.

 

maybe you have a parasitic drain? my last oem tundra battery lasted 7yrs. my wifes last oem camry battery lasted 9yrs. wifes sienna is going strong on 5yrs. mild weather.
