A Compact Square Footprint
The 30mm × 30mm area can be considered when the battery pocket sits near the center of a device rather than along a long internal channel.
3.7 V Lithium Polymer Battery
The 603030 450mAh LiPo battery places a moderate energy target in a 6.0mm × 30mm × 30mm compact square format. It can help OEM teams compare a wider, centered battery pocket with long or thin alternatives before the enclosure and connection path are finalized.

Product Snapshot
The 603030 reference combines 450mAh capacity with a 6mm profile and a 30mm × 30mm plan area. Its near-square footprint gives the mechanical team a different option from the 3.2mm-thin 323540 and the long 651648 format.
The 30mm × 30mm area can be considered when the battery pocket sits near the center of a device rather than along a long internal channel.
The 450mAh rating and approximately 1.67Wh calculated energy provide a defined reference for portable electronics, sensors and compact instruments.

Product Characteristics & Advantages
The 603030 page owns the square compact geometry in the 450mAh group. Its selection logic is different from 323540, which prioritizes thinness, and 651648, which prioritizes a long narrow pocket.
The calculated electrical references provide a structured starting point for charger, load and protection discussions. Share the finished product requirements with ZERNE to confirm the final battery design and assembly details.
The near-square plan area can simplify comparison with housings that have a broad central cavity or a board-surrounded battery space.
Use the 6mm thickness to review cushioning, compression, retention and the position of adjacent components.
The calculated 1.67Wh can support early runtime comparisons for devices with intermittent loads and compact service intervals.
Approximate current references are calculated from the current rated capacity and are intended to start charger and load discussions.
ZERNE can review connector, cable, protection, capacity and mechanical changes when the 603030 pocket needs adjustment.
Battery Calculation
Use the prefilled 603030 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. 225mA is the approximate standard-charge reference for 450mAh.
The 603030 reference values are prefilled: 3.7 V, 450mAh and a standard-charge reference of approximately 225mA. 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 603030 format is most useful when the device can reserve a 30mm × 30mm area and approximately 6mm of cell depth. Review board clearance, retention and cable exit around that square starting point.
Check the pouch footprint against boards, housing ribs, fasteners and service features before fixing the battery position.
Review cell depth, cushioning and final connection or protection components in the enclosure stack-up.
Use calculated energy for early budgeting, then validate the operating interval against the actual duty cycle and cut-off.
A square pocket can still be constrained by lead exit and connector orientation. Include cable details in the mechanical review.
Applications & Solutions
The 603030 format can be evaluated in compact products that have a square or broad internal cavity and need a moderate 450mAh energy reference.
01The square footprint can be considered in selected monitoring or diagnostic products where the battery sits within a broad internal cavity.

The 603030 reference measures 6.0mm in thickness, 30mm in width and 30mm in length.
At 3.7 V nominal voltage, the rated 450mAh capacity gives approximately 1.67Wh of calculated energy before device cut-off and system losses.
Both are 450mAh configurations, but 603030 uses a 6.0mm × 30mm × 30mm square-leaning format while 323540 uses a much thinner 3.2mm × 35mm × 40mm format.
Confirm the charger, protection arrangement, device load, cut-off condition and final electrical limits against the finished 603030 battery assembly.
The approximate current references are calculated from the 450mAh rated capacity and the 3.7 V LiPo family rates. Final limits require configuration validation.
Yes. ZERNE can review capacity, dimensions, connector, cable, protection and assembly requirements around the square battery pocket.
