Nissan NI‑53357 – LiB Leak Decay Tool, 10mm, 1 PSI (OEM High‑Voltage Battery Leak Test Tool)
The Nissan NI‑53357 LiB Leak Decay Tool is a genuine OEM diagnostic tool engineered for performing precise leak‑decay testing on Nissan lithium‑ion battery (LiB) enclosures.

This tool is referenced throughout Nissan EV and hybrid service manuals for battery‑pack diagnostics, enclosure resealing, and post‑repair verification. It ensures accurate pressure decay measurement, helping technicians identify leaks that could compromise battery performance, safety, or longevity.
