Frequently asked questions

What is the LR089861 TCU backup battery?
The LR089861 is the backup battery for the Telematics Control Unit (TCU). It's a lithium-ion cell that powers the emergency call and telematics module if the main vehicle battery is disconnected, so the TCU can still send an SOS signal. JLR section 19K210.
Which models use this TCU backup battery?
This TCU backup battery fits the Discovery 5, Discovery Sport, Range Rover L405, Range Rover Sport L494, Range Rover Evoque L538 and L551, and Range Rover Velar. It supports the telematics control unit across these models, so confirm your vehicle has a TCU.
What are the signs the TCU backup battery needs replacing?
A failing TCU backup battery typically logs a fault for the telematics or emergency call system and may show an SOS warning on the dash. As lithium-ion cells age they lose capacity, so a stored fault for the TCU backup supply usually points to this battery.
