Why Evaluate the 841625 Format?
The 16mm width and 25mm length create a short narrow pocket, while the 8.4mm thickness becomes the main mechanical boundary to review.
3.7 V Lithium Polymer Battery
3.7 V 300mAh Lithium Polymer Battery 841625
The 841625 LiPo battery delivers a 300mAh rated capacity in an 8.4mm × 16mm × 25mm narrow, deeper envelope. Its approximately 1.11Wh energy reference can be evaluated where the battery bay is short and narrow but has room for a thicker cell.

A 300mAh Reserve in a Narrow, Deeper Envelope
The 841625 uses a 16mm × 25mm plan area to concentrate a 300mAh target. This makes it a useful contrast with thinner 300mAh formats when width and length are constrained but depth remains available.
Compare the Thick Format with Usable Energy
The 300mAh rating corresponds to approximately 1.11Wh of calculated energy. Check it against duty cycle and charger access before choosing a deeper cell solely to preserve plan area.

Product Characteristics & Advantages
Thick Narrow Energy Reserve: Why Evaluate the 841625 LiPo Battery?
The 841625 is a thickness-led 300mAh reference. It can help designers keep the plan area compact, but the 8.4mm depth and 180mΩ resistance need to remain visible in the battery-pocket and power-path discussion.
The 841625 is a thickness-led 300mAh reference. It can help designers keep the plan area compact, but the 8.4mm depth and 180mΩ resistance need to remain visible in the battery-pocket and power-path discussion. The calculated electrical references provide a structured starting point for charger, load and protection discussions, while the final battery remains a configurable OEM design.
16mm × 25mm for Narrow Placement
The compact plan area may fit beside a board or within a short device cavity where longer cells are not practical.
8.4mm for a Deeper Battery Bay
The thickness is the key mechanical constraint and should be checked against housing height, cushioning and connector arrangement.
1.11Wh for a 300mAh Target
The calculated energy supports runtime comparison with the thinner 582030 format and other nearby capacity choices.
180mΩ for Peak-Load Questions
Use the listed resistance to identify voltage-drop and startup topics, then validate the complete current path in samples.
Approx. 6.0g Family Reference
The derived mass can be included in early portable-device planning while finished assembly weight remains configuration-dependent.
Battery Calculation
Check 841625 Energy and Estimated Runtime
Use the prefilled 841625 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. 150mA is the approximate standard-charge reference for 300mAh.

How to Use the Result
The 841625 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.
- 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 841625 Battery Around the Depth Limit
For 841625, the main design question is whether the 8.4mm profile can be protected and retained inside the short 16mm × 25mm bay without interfering with the electronics.
Measure the Real Depth Envelope
Compare 8.4mm with the complete housing, cushioning, adhesive or retention method and connector height before releasing the pocket.
Keep the Narrow Plan Area Controlled
The 16mm × 25mm outline can simplify placement, but its edges still need protection from sharp ribs and compression points.
Use the Same-Capacity Comparison
Approximately 1.11Wh is the same energy reference as 582030, so the selection can focus on depth versus length and width.
Check Voltage Drop at the Device Peaks
The 180mΩ listing should be considered with actual peak load, wires, connectors and protection before the design is approved.
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.
