If you own a 2018–2019 Lamborghini Urus and you’ve already seen random battery warnings, no‑start situations, or been quoted a massive repair bill by the dealer, you’re not alone.
These early Urus models left the factory with a lithium battery system that’s known to cause headaches. The cars are incredible, but the battery setup isn’t.
In this post (and the video above), we walk through:
- What’s wrong with the factory lithium system
- What actually fails and why
- How we convert Urus, Cayenne, 992, and Bentayga to a normal 92Ah AGM battery using our kit and OBD dongle
What’s the problem with the 2018–2019 Urus lithium battery?
The short version:
- Early Urus models use a lithium battery + control strategy that’s very sensitive to age, heat, and usage.
- When things start to go wrong, owners see:
- Random warning lights
- Voltage / battery errors
- No‑start or intermittent start issues
- The factory “fix” often involves very expensive lithium components or full replacement, with quotes easily running into the $4–6K range.
It’s not that the Urus is a bad truck – it’s that this battery setup was over‑complicated for what most owners actually need.
Our solution: Lithium‑to‑AGM conversion kit
Instead of trying to nurse along a failing lithium system, we convert these trucks to a conventional AGM battery setup and recode the car to understand it.
We use the same kit on:
- Lamborghini Urus
- Porsche Cayenne
- Porsche 992
- Bentley Bentayga

What’s in the kit?
- Hardware to mount and connect a 92Ah AGM battery in place of the lithium unit
- OBD configuration dongle that updates the car’s coding to AGM
- Instructions and support from a shop that’s actually done this on real customer trucks
The key isn’t just the hardware – it’s getting the car’s electrical management system to know it’s running an AGM, not lithium. That’s what the dongle handles.
