I have one in all my cars; & since I needed one for the NX I got one from Schumacher with long enough cables to reach the correct attachment points.

 

I got one of those, hoping not to use it before 5K/5mo. visit.

 

The lithium ion emergency start is absolutluy the best piece of mind you will ever have

 

Mine charges while driving (not all the time) reads around ~ 14.2V, maybe because the battery is "dying".

 

Can you please share which Schumacher model you purchased that has the longer cables. I just purchased the 2026 Nx and according to manual the jumper connection points are in front.

 

1250 Amp Rugged. $85.00 on Amazon. Reaches jumper points with no problem.

 

How often do you need to charge that? and where do you store it? Thanks!

 

Not sure how often to charge it,I just got it, also have 26 NX. Will have to check specs when I get home; I'm out of town. For now it's on the back seat,plan to put it in hatch, accessible by lowering back seat.

 

I ran across a video about engaging the battery guardian mode.as outlined in the video at the 1:37 minute mark.

 

I wonder if the Lock-Lock has any affects, like using remote Start, or remembering previous settings, etc. Have you tried it?

 

Nice find, but does it actually work?
Your link is off on the timing, it should be more like this:

 

I have a 2022 Lexus NX 350h, bought in September, 2022. In December, I was at the dealership for a regular oil change and asked them to look into the battery. They did take a look without any extra charge and replaced my battery for free. I drive just a few times a week, short distances.
Before replacement my battery showed some signs of issues (like it was 11V), but I was always able to start my car.
After replacement no issues. I went on vacation and left my car in the garage for 4 weeks (It was on some days like -25C outside), and started the car after that without any problems.

 

I have a 2024 NX350h premium and my battery went dead. Could not open any doors but I tried the hatch and it opened. Called Lexus and AAA came and jumped the battery in the back. The car is 2 years old. Lexus advisor said I was lucky that the hatch opened. I hope the new battery will last longer than two years.

 

Unfortunately, it likely won't. I'm at 36 months and on my 2nd battery, and I drive about 15000 KM/year (roughly 9000 miles/year). Best thing for you to do is get a booster, either one that mounts to the battery or, as I have, a portable jump starter. You'll need to read up on how to open your doors with a dead battery and how to properly place the cables on the jump points under the hood. Lots of posts here about this issue. it's really disheartening that this generation of hybrids exhibit this issue. Lexus/Toyota need to step up to properly fix it or they'll lose some customers.

 

I have both one lithium ensemble start hooked directly so you can just blue tooth it to start and also have a jumpstarter in the the back so when i get the door tournament can crawl in and do it manualyy if the other failed
