Why Evaluate the 350926 Format?
The 9mm × 26mm plan area can fit a narrow edge cavity, while the 3.5mm profile keeps the mechanical stack compact.
3.7 V Lithium Polymer Battery
The 350926 LiPo battery provides a 60mAh rated capacity in a 3.5mm × 9mm × 26mm micro-linear envelope. Its approximately 0.22Wh energy reference is intended for early review of very small products where width, depth and total mass are tightly constrained.
Product Snapshot
The 350926 is a minimal-footprint reference with only 9mm width and 3.5mm thickness. It gives product teams a defined starting point for compact battery pockets, low-duty operation and short lead routes.
The 9mm × 26mm plan area can fit a narrow edge cavity, while the 3.5mm profile keeps the mechanical stack compact.
The 60mAh rating and approximately 0.22Wh calculated energy should be compared with actual standby demand, update frequency and charging access before the pocket is approved.

Product Characteristics & Advantages
The 350926 is a micro-cell reference for products that prioritize a very small pocket over a long operating interval. Its 3.5mm profile, 9mm width and 400mΩ resistance make low-power duty-cycle planning especially important.
The 350926 is a micro-cell reference for products that prioritize a very small pocket over a long operating interval. Its 3.5mm profile, 9mm width and 400mΩ resistance make low-power duty-cycle planning especially important. The calculated electrical references provide a structured starting point for charger, load and protection discussions, while the final battery remains a configurable OEM design.
The narrow width can help fit a small battery beside a board or along an enclosure wall where wider cells cannot be placed.
Use the thickness to check housing clearance, cushioning and the lead or connector route in a very small enclosure.
The calculated energy supports early comparison of standby, short sensing events and limited wireless activity.
The listed resistance makes it important to compare peak load and voltage margin before selecting the configuration for a burst-heavy device.
The derived mass can support ultra-compact product weight planning, while the finished assembly will vary with leads and protection.
Battery Calculation
Use the prefilled 350926 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. 30mA is the approximate standard-charge reference for 60mAh.
The 350926 reference values are prefilled: 3.7 V, 60mAh and a standard-charge reference of approximately 30mA. 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
For 350926, the pocket and duty cycle should be designed together. Review the 3.5mm depth, 9mm width, 26mm length, 60mAh capacity and 400mΩ listing against the actual load.
A 9mm-wide cell leaves little room for sharp housing features, so plan the retention and cable exit before finalizing the miniature enclosure.
The linear shape can follow a narrow channel, but service access and bend radius still matter in a small assembly.
Compare the calculated energy with sleep current, wake events and charging frequency instead of assuming a fixed runtime.
The 400mΩ reference warrants an explicit voltage-drop discussion with actual burst current, connector resistance and cutoff conditions.
Applications & Solutions
The 350926 can be evaluated in very compact products where the battery pocket is narrow and the device duty cycle is modest enough for a 60mAh energy target.
01The 3.5mm × 9mm × 26mm profile is a compact reference for hearing-aid designs where a slim cell must fit beside acoustic and charging hardware.

Share the 9mm × 26mm channel, 3.5mm depth, standby profile and charging method so the 60mAh configuration can be reviewed without overestimating runtime.
For a micro-cell RFQ, the device duty cycle is as important as the available physical pocket.
ZERNE can compare the 451220, 401224 or a custom capacity and geometry when the 350926 energy target does not cover the finished duty cycle.
