12 volt battery
Lbeex replied to Alan Salisbury's topic in Lexus LBX Owners Club - The All-New Lexus LBX
I would not give any confidence to neither SoC reading (not based on battery voltage drop under load), neither car location (which is smartphone location in fact), etc., but voltage readings are really fine (verified using a multimeter before installed). SoI am satisfied with just Voltage, and do not need anything more from BM200. BTW: I installed this monitor on Monday 18th. Below are the readings till today (Friday), with my comments. You may notice that with my driving habits the battery charge balance is not maintained and there is slight drop of voltage. On 21th I charged the battery fully using a charger. Tomorrow I am going drive around 85 km, and show you next graphs. -
This voltage display will not give you conclusive reading, because, if you are in Ready mode, the battery is charged by DC-DC converter, so the voltage will be "high". If you are not in Ready mode, the lighter socket is disconnected. So the best way is to use a kind of multimeter connected to the jump start points as shown in LBX manual. If you still prefer to use this gadget, you may switch to ACC mode (see instructuion manual!!), for a while! This again will show you battery voltage under some load so probably underestimated.

12 volt battery
Lbeex replied to Alan Salisbury's topic in Lexus LBX Owners Club - The All-New Lexus LBX
Today, there were no issues starting the engine after the car had been parked for a week (no wonder, given the fully charged battery following the Lexus Battery Xchange). On Monday, I'll be installing a BM200 monitor, which will allow me to track the battery more accurately in the future, and share this experience with you. However, I believe that, in general, car owners should remain vigilant about their 12V battery after any service—whether it's a routine inspection, wheel change, or even the delivery of a new car. Often, service centers don't fully recharge the 12V battery, which can lead to long-term imbalance, particularly for owners who do a lot of short-distance commuting or drive in poor weather conditions (e.g., dark, rainy days). This increases the risk of the battery failure. I’ve experienced this issue occasionally with previous cars, even those with fewer electronics, but it would typically take about two weeks for the battery to show signs of strain. The Lexus LBX seems to require more attention in this area, but Lexus hasn’t adequately addressed it. While earlier Lexus models included a 12V battery voltage monitor, this feature has been removed in newer models. As a result, I’ll need to install my own monitor at my expense. I’m unsure why Lexus decided to eliminate this feature, but I suspect it was because the voltage readings were confusing for non-technical users. Nonetheless, Lexus should have at least made it an optional feature, rather than removing it entirely. And Hey Lexus: are you aware that it is not allowed to have engine running while not moving the car for longer than 1 minute, at least in my country (EU). So the solution to charge battery by staying in READY mode is not that brilliant solution. -

A bit off topic, I can tollerate it, except when in EU bonging overrides navigation voice in Android Auto -
Tracker - any experience with LBX?
Lbeex replied to Iain24's topic in Lexus LBX Owners Club - The All-New Lexus LBX
If you install front & rear dashcams, for security when parked, you may end up with battery depletion issue, not only in LBX but any car, unless you install cut-off that disconnects supply from 12V battery when voltage drops below certain level. Tracker - if you mean GPS tracker, this is an option but the signal can be jammed (as well as GSM). I have one, and it need recharge every 2 weeks. My dealer installed an alarm that is blocking OBD scanning, and they attached low energy Bluetooth proxi card without which you cannot start the engine, even if a thief is already inside a car after scanning your keys.- 1 reply

12 volt battery

Instead of assuming and/or expecting the vehicle will be in regular use, Lexus designers should challenge the issue, which is truly a real issue. I used to park my LBX in underground parking, and I retired still working remotely part time. So my fault? Modern cars are stuffed with electronics which is the prime cause of the 12V battery depletion, BUT: · why Lexus is not providing any means to monitor 12V battery voltage and/or charge, no efficient warnings in the Lexus car system! · why Lexus is not providing acceptably convenient way and access to charge it up within reasonably time, · why Lexus attached to my new car a bottle of French champain instead of jump starter, being aware of this long standing issue I still like my LBX but not that much as I would and as Lexus designers assumed -

Thank you. Now, I wonder where is a place in the LBX designated to support the lift? -

Answering your question: Since they did not question the battery replacement, I -being satisfied - did not ask them to install a monitor and charger cable/socket for free. The hardware is cheap. They did not question nor objected the need to install it neither, which is indicative of some suggestion they got from Lexus. BTW: solar panel is a smart idea, because you do not need long cable to mains regardless where you parked. I am wondering, looking at my LBX black roof, why Lexus - as an innovative company – did not install flexible solar foil on a part of surface of the roof. Maybe they are waiting with introduction to keep it for the purpose of future attracting of customers. Anyway, the technology is available: see for example https://sauletech.com/ The author of the invention is a Polish scientist woman Olga Malinkiewicz. -

Thank you Don C ! BTW: Lexus service replaced my LBX battery for a better & bigger one, as I wrote in another post. It was in a rush, so next week they will install a monitor and charger socket as I requested. Anyway I noticed something interesting before the replacement already:- Previously - with this poor battery - when I started driving after say 3 days, the engine after warming up tends to increase revs up to 5000 rpm even during really small acceleration! It was for a minute or so, but rather with annoying sound and vibration. I suppose it was a kind of emergency mode to charge this dying battery. Then normal behavior, sound, and vibrations. Now, after replacing 12V battery, all these above symptoms disappeared! -
Spacesaver spare wheel for LBX
Lbeex replied to P M R's topic in Lexus LBX Owners Club - The All-New Lexus LBX
Could you please send us the link or specification of the spare wheel and eqiuipment? I did not found any wrench for wheel bolts in my LBX, only this standard flat tire emergency equipment. However, my dealer included a special key socket for anti-theft bolts they installed for free – but not very consistent. Today, I do not consider buying a wrench, lift and spare wheel having Lexus support within warranty period, but leter probably I do. (BTW: my previous car was Subaru Forester XT 2016 which had pare wheel included, and earlier XT 2009 which had full size wheel!) -

I would log out and delete cookies, then log in. Strange anyway. -

For 2WD version ok, but for 4WD it is probably not acceptable for most users. -

Thanks for the bolts diameter information. I have the same monitor as well. It draws 2.5mA as specified, so ok. I am going to install it together with standard SAE cable, socket and fuse assembly to connect to a charger easily:
