A Balanced Compact Format
The 20mm × 30mm plan area provides a defined pocket for a mid-sized compact battery, while 6mm thickness helps the team check the depth of the enclosure stack.
3.7 V Lithium Polymer Battery
The 602030 300mAh LiPo battery combines a 6.0mm profile with a 20mm × 30mm footprint and approximately 1.11Wh of calculated energy. It gives OEM teams a compact square-leaning reference for comparing enclosure space, runtime and connection access.

Product Snapshot
The 602030 configuration places 300mAh in a 6mm × 20mm × 30mm envelope. Its compact plan area is useful for products that need more capacity than a micro cell but cannot reserve a long or wide battery pocket.
The 20mm × 30mm plan area provides a defined pocket for a mid-sized compact battery, while 6mm thickness helps the team check the depth of the enclosure stack.
The 1.11Wh calculated energy reference supports early runtime comparison for compact electronics whose duty cycle is larger than a very small wearable cell but below a high-capacity device.

Approximate weight follows the 3.7 V LiPo family reference. Current and energy values are calculated planning references, not measured limits; confirm the final charger, protection and load specification for the finished battery.
Product Characteristics & Advantages
The 602030 page focuses on balanced compact packaging. It is differentiated from the thinner 582030 by depth, from the lower-capacity 502030 by capacity, and from the wider 603030 by battery-pocket geometry.
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 plan area can fit a compact central or edge-mounted pocket while leaving the team a clear basis for reviewing board placement and retention.
Use the listed thickness when checking adjacent components, cushioning, compression and the final protection or connection arrangement.
The capacity gives a practical starting point for comparing standby intervals, sensing cycles and intermittent communication.
Capacity-based current references support early charger and load planning; confirm the final electrical limits for the completed configuration.
ZERNE can adjust capacity, lead arrangement, protection, connector and mechanical details when the 602030 pocket needs a different configuration.
Battery Calculation
Use the prefilled 602030 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. 150mA is the approximate standard-charge reference for 300mAh.
The 602030 reference values are prefilled: 3.7 V, 300mAh and a standard-charge reference of approximately 150mA. 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 602030 should be reviewed as a compact rectangular pouch rather than as a capacity number alone. Check the 6mm depth, 20mm × 30mm area, cable route and retention method against the complete housing.
Keep the battery footprint clear of housing ribs, board components and compression points, then add the clearance required by the finished assembly.
Review the cell thickness in the stack-up together with cushioning and any protection or connector components.
Use the calculated energy for an early budget and account for cut-off, load, temperature and system efficiency during validation.
Use the rated capacity and calculated references for early planning, then confirm the charger, protection and load limits for the finished battery assembly.
Applications & Solutions
The 602030 300mAh format can be evaluated in compact IoT, wearable and tracking products where a 20mm × 30mm battery pocket is easier to allocate than a long narrow cell.
