A Mid-Range Energy Step
The 3500mAh configuration can extend the operating interval beyond smaller reference cells while keeping the package below the larger 4.4Ah and 6.2Ah formats.
3.7 V Lithium Polymer Battery
The 775767 lipo battery combines a 3500mAh rated capacity with a 7.7mm × 57mm × 67mm rectangular envelope. Its approximately 12.95Wh calculated energy reference provides a balanced route for portable devices that need more reserve without moving to the largest pouch formats.

Product Snapshot
The 775767 sits between compact 2.3–3.0Ah references and larger high-capacity formats. Its 7.7mm depth, 57mm width and 67mm length create a practical comparison point for products that need more energy but still have a controlled enclosure.
The 3500mAh configuration can extend the operating interval beyond smaller reference cells while keeping the package below the larger 4.4Ah and 6.2Ah formats.
The 57mm × 67mm footprint gives OEM teams a defined battery bay for reviewing board placement, retention and cable access.

Product Characteristics & Advantages
The 775767 is a balanced mid-range option: enough energy for active portable equipment, a confirmed 7.7mm profile and an approximate 70g weight. It is best compared against thinner, smaller and higher-capacity formats according to the finished enclosure.
The 775767 is a balanced mid-range option: enough energy for active portable equipment, a confirmed 7.7mm profile and an approximate 70g weight. It is best compared against thinner, smaller and higher-capacity formats according to the finished enclosure. The calculated electrical references provide a structured starting point for charger, load and protection discussions, while the final battery remains a configurable OEM design.
Use the capacity to compare print sessions, handheld use, radio activity or measurement intervals with the real load profile.
The thickness should be checked with cushioning, protection, connector height and the surrounding PCB.
The plan area can support a stable battery pocket while leaving the enclosure team clear mechanical boundaries.
Carry the confirmed approximate weight into mounting, balance and user-handling decisions.
Use the confirmed cycle-life value to define validation questions, not as a universal field-life promise.
Battery Calculation
Use the prefilled 775767 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. 1750mA is the approximate standard-charge reference for 3500mAh.
The 775767 reference values are prefilled: 3.7 V, 3500mAh and a standard-charge reference of approximately 1750mA. 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 775767 should be reviewed around the 7.7mm depth and 57mm × 67mm pocket. Confirm how the pouch sits beside the board, connector, protection and user-facing enclosure surfaces.
Reserve space for cushioning and the finished battery assembly rather than treating the nominal cell thickness as the full pocket depth.
Translate approximately 12.95Wh into runtime only after accounting for duty cycle, cutoff, temperature and system losses.
The approximate weight can influence handheld balance, mounting and drop-performance requirements.
The confirmed 1750mA maximum charge and 3500mA discharge references should be checked against the selected charger, protection and wiring.
Applications & Solutions
The 775767 is a useful reference for portable products that need a mid-range energy reserve and a defined rectangular bay without moving immediately to a very large pouch.
01The 3500mAh target can be compared with repeated print sessions and motor pulses while the 57mm × 67mm pocket is checked against the housing.
