Product Characteristics & Advantages
Narrow Mid-Range Battery Pocket: Why Evaluate the 751328 LiPo Battery?
The 751328 is a narrow mid-range reference for products that need a compact 250mAh reserve without moving to a broad square cell. Its main decision axes are width, depth, energy and the listed 150mΩ resistance.
The 751328 is a narrow mid-range reference for products that need a compact 250mAh reserve without moving to a broad square cell. Its main decision axes are width, depth, energy and the listed 150mΩ resistance. The calculated electrical references provide a structured starting point for charger, load and protection discussions, while the final battery remains a configurable OEM design.
13mm for a Narrow Device Bay
The compact width can preserve room for a board, antenna or enclosure wall around the battery.
250mAh for a Defined Reserve
The calculated 0.93Wh reference supports early comparisons of reporting, sensing and short active use.
28mm for Concentrated Placement
The length keeps the pocket compact while offering more plan area than micro-capacity references.
7.5mm for Stack-Up Review
Check the thickness with housing features, cushioning, connector height and the complete protection arrangement.
150mΩ for Power-Path Planning
Use the listing to frame startup and load questions, then validate the final assembly under the device profile.
Battery Calculation
Check 751328 Energy and Estimated Runtime
Use the prefilled 751328 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. 125mA is the approximate standard-charge reference for 250mAh.

How to Use the Result
The 751328 reference values are prefilled: 3.7 V, 250mAh and a standard-charge reference of approximately 125mA. 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 751328 Battery in a Narrow Mid-Range Bay
The 751328 should be reviewed as a compact narrow pouch. Confirm the 7.5mm depth, 13mm × 28mm pocket, connector access and 250mAh energy target together.
Reserve the Narrow Outline
Keep the 13mm width clear of housing ribs and plan retention without adding pressure to the pouch edges.
Use the Short Length Efficiently
The 28mm dimension can fit beside the PCB or within a small instrument cavity, but lead exit and service access still need room.
Compare 0.93Wh with the Duty Cycle
Use the calculated energy to assess reporting interval, sensing time and the desired recharge schedule.
Check the Complete Load Path
Consider the 150mΩ listing with peak current, connector and wires before approving the charger and protection arrangement.
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.
