Service Discontinuation Notice

Due to parts obsolescence, factory repair services for the LI-6400XT will end on December 31, 2025. We will continue to offer factory recalibration, but factory repairs will no longer be available. If you have an LI-6400XT, we recommend that you schedule factory service for your LI-6400XT before December 31, 2025.

Service on the original LI-6400 ended in March 2018. LI-6400s that have been upgraded to the LI-6400XT are eligible for service until December 31, 2025.
