ZuBat Diagnostic Service is widely used not only for vehicle-mounted batteries but also by businesses involved in consumer devices.

This page introduces case studies that demonstrate how the service solved battery‑related challenges across various industries.

■ Portable Wi‑Fi Hotspot Rental Provider

Challenges

With 10,000 to 20,000 portable Wi‑Fi units rented out each month, performing 100% inspection was nearly impossible due to the 10‑hour inspection time required per unit.
This meant that degraded units were unknowingly rented out, leading to customer complaints and refund claims.

After Introducing the ZuBat Diagnostic Service

Instant diagnostics enabled the quantification of battery condition across all units, allowing only devices in good condition to be rented out. As a result, battery‑related complaints dropped to zero.

■ Electric Mobility Manufacturer

Challenges

Ideally, all units should undergo 100% inspection to ensure that the installed batteries are free of initial defects. However, because inspections required significant time, only spot checks were conducted. As a result, units with defective batteries escaped detection and reached the market, causing additional operational workload.

After Introducing the ZuBat Diagnostic Service

Implementing 100% inspection helped prevent the leakage of initial defects. As a result, customer complaints and refunds were prevented, and no defective products reached the market.

■ Radio Equipment Rental Provider

Challenges

When radio equipment malfunctioned, maintenance was required. However, because it was unclear whether the failure originated in the unit or the battery, separate quotations had to be prepared for both the unit and the battery.

After Introducing the ZuBat Diagnostic Service

Instant identification of whether the issue lay with the battery or the unit enabled a significant reduction in in-house workload.
