Thin Profile, Defined Energy Target
The 6mm thickness helps teams screen shallow housings while the 850mAh capacity provides a clear starting point for standby and active-load planning.
3.7V Lithium Polymer Battery
The 603048 lipo battery combines an 850mAh rated capacity with a 6mm-thick, 30mm × 48mm rectangular format. Its approximately 3.15Wh energy reference and slim depth give OEM teams a practical starting point for long-pocket products where enclosure height and operating interval must be balanced.

Product Snapshot
The 603048 reference places an 850mAh energy target inside a 6mm profile and a 30mm × 48mm footprint. This combination is useful when a product has a defined linear pocket but limited depth for the cell, cushioning and cable route.
The 6mm thickness helps teams screen shallow housings while the 850mAh capacity provides a clear starting point for standby and active-load planning.
The 30mm × 48mm footprint can be compared with a device pocket that is longer than it is wide, leaving room to review retention and connector access along the enclosure edge.

Product Characteristics & Advantages
The 603048 is best evaluated as a slim rectangular reference rather than as a capacity number alone. Its approximate 17g family weight reference, 6mm thickness and calculated current values help the mechanical and electrical teams discuss the same starting configuration before samples are built.
The 603048 is best evaluated as a slim rectangular reference rather than as a capacity number alone. Its approximate 17g family weight reference, 6mm thickness and calculated current values help the mechanical and electrical teams discuss the same starting configuration before samples are built. The calculated electrical references provide a structured starting point for charger, load and protection discussions, while the final battery remains a configurable OEM design.
The rated capacity supports early comparison of reporting intervals, active use and standby requirements without turning the page into a generic capacity claim.
The slim profile provides a concrete boundary for housing depth, cushioning, compression risk and clearance around the finished battery assembly.
The longer rectangular plan area can help align the battery with a board edge, handheld grip, tracker shell or other elongated product space.
The calculated charge and discharge references give the power team early inputs for charger and load discussions while the final limits remain configuration-specific.
The family-derived weight reference can be included in an early portable-device budget, then replaced by the finished battery assembly weight during validation.
Battery Calculation
Use the prefilled 603048 values or enter your own load assumptions for a quick energy and runtime estimate.
Energy is calculated from nominal voltage and capacity. Runtime uses the entered load power and an adjustable efficiency assumption.
Approx. 425mA is the approximate standard-charge reference for 850mAh.
The 603048 reference values are prefilled: 3.7V, 850mAh and a standard-charge reference of approximately 425mA. Adjust the load power and efficiency to compare operating scenarios; the calculator does not infer safe limits from capacity alone.
Use the result for early comparison, then confirm the charger, protection, connector and final battery specification through sample testing.
Integration Guidance
The main integration question for 603048 is how the 6mm cell depth and 30mm × 48mm footprint sit inside the device stack-up. Review the battery pocket, lead exit and service clearance together with the 850mAh energy target.
Start with the 6mm cell dimension, then add the clearance required for cushioning, retention and the final protection or connection arrangement.
Place the 48mm length where it supports a stable retention feature or a clean cable route instead of forcing the pouch into a short cavity.
Approximately 3.15Wh supports initial runtime comparison, but radio bursts, displays and cutoff settings can reduce the usable operating window.
Use the calculated current references for early power-path discussion and confirm the final charger, protection and load limits with the approved design.
Applications & Solutions
The 603048 format may suit compact products that need a slim battery pocket with more plan length than width. These application paths focus on where the 6mm profile, 850mAh energy target and approximately 17g reference weight should be evaluated together.
