PKCell Extended Runtime for Fruit Container Temperature Control – Chile
Background / Challenge
A leading fruit exporter in Chile relies on refrigerated shipping containers to maintain temperature-sensitive produce such as cherries, grapes, and blueberries during long ocean and land transport. Their existing FR14505 9V 5800mAh battery packs powering the temperature monitoring devices were falling short in runtime, requiring frequent replacements.
This led to:
-
Increased maintenance costs
-
Risk of temperature excursions during long-haul trips
-
Inconsistent temperature data due to premature power loss
The client sought a drop-in battery solution with longer runtime, stable output, and reliable cold-chain performance.
Solution
PKCELL’s engineering team proposed an innovative dual-battery pack solution that enhanced capacity without altering the device’s physical layout:
-
Primary Module: 9V 5800mAh – ensured voltage compatibility and device stability
-
Booster Pack: 3V 2900mAh in parallel – added 50% more energy for extended runtime
-
Combined Capacity: 8700mAh – a 50% increase over the original battery setup
This hybrid design extended the operational life of the temperature monitoring system significantly, reducing the battery replacement frequency and improving overall cold-chain data reliability.
