A Compact 80mAh Reference for Low-Power Products
The rated capacity gives a clear starting point for compact electronics that need a small rechargeable energy reserve and a short, defined battery pocket.
3.7 V Lithium Polymer Battery
3.7 V 80mAh Lithium Polymer Battery 451220
The 451220 80mAh LiPo battery uses a 4.5mm × 12mm × 20mm envelope for very small rechargeable products that need a little more energy than the 70mAh configuration. It gives OEM teams a capacity-specific reference for comparing runtime, pocket fit and connection access without changing the compact format.

A Small Battery Format with a Defined Capacity Step
The 451220 80mAh configuration combines a small rectangular footprint with approximately 0.30Wh of calculated energy. The dimensional format can help teams compare the higher capacity option with the 451220 70mAh reference before final runtime and charging requirements are confirmed.
Keep the Pocket Small While Comparing Runtime
The 4.5mm × 12mm × 20mm envelope keeps the mechanical discussion focused on depth, lead exit and retention rather than on a larger battery cavity.

Product Characteristics & Advantages
An 80mAh Capacity Step in a Compact 451220 Envelope: Why Evaluate the 451220 LiPo Battery?
The 451220 80mAh page is positioned around a small capacity step within a compact dimensional envelope. Its value is easiest to assess when the device team compares energy demand, battery-pocket clearance, connector access and the difference between the 70mAh and 80mAh configurations.
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.
80mAh for a Defined Low-Power Budget
The 80mAh rating provides a specific energy target for products where a modest increase over the 70mAh option may improve the operating interval without changing the battery pocket.
12mm × 20mm for Compact Placement
The short plan area can be reviewed in small housings, board-edge pockets and miniature products where every millimeter affects assembly access.
A Clear Depth Boundary for Enclosure Design
Use the 4.5mm thickness to check housing clearance, cushioning, retention and lead routing before the mechanical stack-up is released.
Capacity-Based References for Early Charger Review
The calculated current values offer early inputs for charger and load discussions. The final operating limits remain part of the final battery configuration.
A Reference Format Rather Than a Closed SKU
ZERNE can review capacity, connector, protection and wiring requirements when the 451220 envelope or the 80mAh target does not match the finished device.
Battery Calculation
Check 451220 Energy and Estimated Runtime
Use the prefilled 451220 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. 40mA is the approximate standard-charge reference for 80mAh.

How to Use the Result
The 451220 reference values are prefilled: 3.7 V, 80mAh and a standard-charge reference of approximately 40mA. 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
Fit the 451220 80mAh Battery Inside a Small Device Pocket
The 451220 should be evaluated as a compact assembly. Reserve the 12mm × 20mm plan area, check the 4.5mm depth and review the lead exit, retention method and final protection arrangement around the cell.
Reserve the Short Battery Pocket
Keep the 12mm × 20mm area clear of board components, housing ribs and compression points. The finished assembly may require additional clearance.
Compare the 0.30Wh Energy Reference
Use the calculated energy to screen standby time, reporting frequency and active load. Actual usable energy depends on the device cut-off and operating profile.
Plan Lead and Connector Access
The connector and cable route can take a meaningful share of a very small enclosure. Confirm exit direction, bend radius and service access before sampling.
Use the Capacity Variants Intentionally
Compare the 70mAh and 80mAh versions against the same battery pocket while keeping the runtime target and load profile visible in the selection discussion.
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.
Applications & Solutions
Applications for the 451220 80mAh LiPo Battery
The 451220 80mAh format can be considered for compact products where a small battery pocket and a defined low-power energy target are more important than a large capacity reserve.
01Wearable and Personal Electronics
The 4.5mm profile and short footprint can help teams examine battery placement in compact wearable housings, provided the finished product can accommodate the pouch and connection arrangement.
