Thin Profile with a Larger Plan Area
The 4mm thickness gives mechanical teams a clear starting boundary for shallow enclosures, while the broad footprint should be reviewed against the full device stack-up.
3.7V Lithium Polymer Battery
3.7 V 900mAh Lithium Polymer Battery 404355
The 404355 lipo battery combines a 900mAh rated capacity with a 4mm × 43mm × 55mm broad rectangular format. Its approximately 3.33Wh energy reference is suited to early design discussions where a thin cell can spread across a wider, longer battery pocket without taking much enclosure depth.

A 404355 Format for Thin, Broad Battery Pockets
The 404355 reference places a 900mAh energy target in a 4mm profile and a 43mm × 55mm plan area. This geometry is worth evaluating when the enclosure can allocate surface area but has limited height for the pouch, cushioning and finished protection arrangement.
900mAh for a Defined Energy Window
The calculated 3.33Wh reference supports early comparison of runtime, recharge interval and active-load demand before the final battery assembly is approved.

Product Characteristics & Advantages
Ultra-Thin Broad-Footprint Integration: Why Evaluate the 404355 LiPo Battery?
The 404355 is a surface-area-led reference rather than a narrow-channel cell. Its 4mm depth, 43mm × 55mm footprint and approximately 18g family weight reference help the mechanical and electrical teams decide whether a broad, shallow battery pocket is more practical than a thicker or longer alternative.
The 404355 is a surface-area-led reference rather than a narrow-channel cell. Its 4mm depth, 43mm × 55mm footprint and approximately 18g family weight reference help the mechanical and electrical teams decide whether a broad, shallow battery pocket is more practical than a thicker or longer alternative. The calculated electrical references provide a structured starting point for charger, load and protection discussions, while the final battery remains a configurable OEM design.
4mm for Shallow Enclosure Planning
The thin profile can preserve vertical space for a display, board, sensor, cover or structural assembly, subject to finished-pack clearance.
43mm × 55mm for Broad Placement
The plan area provides a concrete boundary for reviewing a wide battery bay, surface retention and cable exit before the enclosure is frozen.
3.33Wh for Runtime Comparison
The calculated energy gives the product team a starting point for comparing active sessions, standby intervals and desired recharge frequency.
Approx. 18g for System Budgeting
The family-derived weight reference can be included in a preliminary portable-device mass budget and replaced with finished assembly data during validation.
Approx. 450mA Standard-Charge Reference
The capacity-derived current values support early charger and load discussions while final current limits remain configuration-specific.
Battery Calculation
Check 404355 Energy and Estimated Runtime
Use the prefilled 404355 values or enter your own load assumptions for a quick energy and runtime estimate.
LiPo Battery Capacity Calculator
Energy is calculated from nominal voltage and capacity. Runtime uses the entered load power and an adjustable efficiency assumption.
Approx. 450mA is the approximate standard-charge reference for 900mAh.

How to Use the Result
The 404355 reference values are prefilled: 3.7V, 900mAh and a standard-charge reference of approximately 450mA. Adjust the load power and efficiency to compare operating scenarios; the calculator does not infer safe limits from capacity alone.
- Energy = voltage × capacity ÷ 1000
- Runtime estimate = energy × efficiency ÷ load power
- Ideal charge time = capacity ÷ entered charge current
- Actual runtime depends on load profile, temperature, cutoff and system losses
Use the result for early comparison, then confirm the charger, protection, connector and final battery specification through sample testing.
Integration Guidance
Integrate the 404355 Battery Across a Broad, Shallow Pocket
The main integration question for 404355 is whether the 43mm × 55mm footprint can be retained without creating pressure points, while the 4mm depth remains compatible with cushioning, protection and connector clearance.
Reserve the Shallow Stack-Up
Use the 4mm cell thickness as the starting point, then add the clearance required for cushioning, retention and the finished protection arrangement.
Control Pressure Across the Broad Face
A wider pouch benefits from even support. Avoid localized housing features that could press directly on the cell during assembly or service.
Plan the Cable Exit Before Tooling
Review lead direction, connector height and bend radius against the 43mm × 55mm battery bay rather than adding the cable route after the enclosure is complete.
Compare 3.33Wh with the Real Load
Use the calculated energy for early runtime comparison, then validate cutoff, temperature, radio activity and peak-load behavior with samples.
The stated dimensions and calculated values are reference inputs for design planning. Confirm the finished battery drawing, tolerance, protection, connector and test conditions before production release.
