Another flat battery on Brand New LC

[t3lcfe]

Dealer replaced the battery after 18 months use and failed the dealer test. Dealer must have the “battery failure” proof /print to show Toyota to get pay for the replacement.
Since that day, I had BS200 installed.
FY reference, this attached short video shows how anytime I monitor the LC battery health and performance through my iPhone Bluetooth

Someone will pony up for a lithium battery that addresses most of the issues expensively, and post about their experiences! These batteries address the performance issues by allowing deep discharges, having an onboard battery management/remote monitoring system, and self-starting capacity. The current mfgs (Antigravity, Optima Orangetop, MEGA-LiFe, etc) spec their batteries to be good to around 0F and can be charged safely on OEM charging systems. The track/sports car community has been using them for many years and the off-road/overlanding community has been slowly adopting them in the last few years. Just like sealed lead acid and AGM batteries, these will be debated for decades to come, but as prices come down, they will become more common. Some lesser known OEMs like Porsche, Ferrari, and McLaren have been using lithium starting batteries. Their starting battery use is somewhat similar - frequent deep discharges due to not being daily driven cars. At their price point, they probably could afford installing AGM batteries instead if they performed better .

just curious, did you install it where the jack is, or on top of the battery?

On top of battery, but slide it toward the front where the big cavity/space. That space will keep the BS200 tight without moving around. For more secure, you can add zip ties.
With that unit, I monitor the battery health status every day

Took mine to the dealer. Tested and replaced the battery. A little sketched out at the idea of recurrence in a remote area so going to buy a jump pack and hope to never use it.

Related topic. Accessing the 12V under the hood is a bit of a pain. Has anyone had experience installing terminals under the hood to make it easier?

While not addressing terminals under the hood per say.......... several members have installed winches and have ran dedicated cables from the 12v battery in the rear to the under-hood area. I myself, tapped into the under-hood jumper cable buss bar and have a circuit breaker protected 12v source that powers my "on-board" air compressor and a few other things.

Full details are on my build page.........

To fix the LC hybrid “12v battery thing”, I had this system permanently connected to LC 12v battery. Even if the battery juice is low, the BS200 will start the engine.
Also, it can help the battery life longer.
With that I can monitor the level of juice, charge and discharge time/percentage…
I like it.

I got hit with a dead battery a couple of weeks ago after being in ACC mode and listening to music while working on something. I had opened the door and restarted the ACC mode a few times. I'm around 38k miles and never had issues before. I guess I should have respected the ACC timeout.

This BS200 looks nice and I like that you can remotely monitor the levels and enabled it. I question, however, if this will this solve the low/dead battery starting issue on the LC250? My understanding was the 250 mostly uses the 48v hybrid battery to start the engine, except after popping the gas tank door where it then uses the starter motor, and the problem with starting is a low 12v battery will not keep the computer systems running that are needed to bring the system online in order for the systems to start and run.
It was for this reason why a battery booster, like the Noko, which has an override of a common 30 second shutoff, is needed so it can power the computers long enough to come online before starting. I used my Noko's 30 sec override to bring mine back to life, thinking this was the case anyway.

It sounds like the BS200 uses starting capacitors for long term storage with high cranking amps instead of batteries and only assists with the cranking load during a start. I could be wrong about all of this, but, it doesn't seem like it will provide a steady 12v supply long enough to power up the computers and a separate power source would still be needed.

If the above is correct, would popping the gas door to trigger the next start to use the starter motor instead of the 48v system perhaps work with the BS200 or boosters without a timer override to start the engine or would the computers still need to be online for the LC250 to be started this way?

Can't speak for the Noko, but my capacitor jump box didn't have an issue....

@Varcy I had the same thoughts and I asked Ancel directly. Here is the reply that I got in July…
“Dear Customer,

Thank you for your inquiry, and we apologize for the delayed response.

Regarding your question about the BS 200 Super Starter and your 2027 Toyota Land Cruiser hybrid – unfortunately, this product is not compatible with hybrid vehicles of this type.

We appreciate your understanding and apologize that we are unable to assist further with this particular application.

If you have any other questions, please feel free to reach out.

I certainly can’t argue with the experiences that folks have had with actually using capacitor based devices, and my guess is that Ancel’s reply is more out of caution since they may not have all of the exact details on all of the various hybrid starting schemes, but I’m going to heed Ancel’s advice on the BS 200.

EVERY brand out there gets the occasional battery with a dead cell. Plain and simple.
They ship across the pond, ??disconnected I hope, but as said above at port they are almost never fully charged, or just plain discharged from sitting on the lot. If a battery has a bad cell, it WILL fail.

Very true. With the demand, our Land Cruisers aren’t sitting around in ports the way many other overseas shipped vehicles do from processing delays & slow sales rates. For years I had a plug in Solar panel maintainer w/a cigarette lighter plug that I picked up off eBay, & it had a VW part number. Lots of crew used them on our airport vehicle in long term parking. They still sell them on eBay now w/ OBDII plugs.

I have tried a "Lay on the dash" type solar charger on my 280 SLK, it worked well until the sun and I assume the magnifying effect of the windshield , warped the plastic housing so bad some of the internal components were exposed to a point I felt may cause a short circuit. I promptly disposed it and went back to a wall plug C-Tek charger. For long term use, I'd be careful......

On my LC, I did install a similar type plastic housed solar charger on the roof, under the roof rack and it seems to be holding up well after a year + of use.

I'll be traveling few times to the North-West Maine for grouse and deer hunting in October and November as usual. Logging roads and very spotty cell connections. I have stock 2025 LC LC with 16K miles. After reading all those post about dreaded 12V battery issues I checked it last night-only 11.8 volts! Quick call to my dealer this morning and got a new TrueStart battery installed under warranty because original battery failed the test. I had 5 4Runners 3-5 generations and never had to touch a battery in less than 4-5 years....But even last year I took a jump box with me anyways.

IMO it's the DC to DC inverter that uses the hybrid battery to charge the 12v battery, there's a miscalculation in the software/procedure that allows the charging to happen. Seems to me that when the vehicle goes to sleep so does the charging of the 12v battery. The 12v battery does have a monitor on it but it doesn't seem to allow the charging system to work without the vehicle in run mode. FYI......... 12.8v is where mine normally measures even with the trickle charger attached.

Kind of wished they would retrofit a conventional Alternator that was completely divorced from the hybrid system.......... I'd pay for the parts!

Should be able to do it, just need to know the parts list that the PIO is using.
They were doing it with the 4Runner Hybrids
only certain models with a very specific PIO will get an alternator in a hybrid.

from my understanding only the TH and PRO can add the aux switch option and get the alternator on the hybrid.

the aux dc to dc switch panel is standard on TH, TRD Pro and option package on TRD Off-Road Premium i-FORCE MAX.

The computers still need to come online in order to start the LC.

Wondering if it was easy to install and by any chance to you have any pictures ?
