Product Description
For a design using the 90 x 190mm pouch format, the 40Ah cell offers a different thickness and current specification from the 33Ah version. Compare the full-charge thickness, tab geometry and cell mass before treating the two as interchangeable. The capacity table distinguishes 40Ah nominal from 39Ah minimum; both belong in sample acceptance planning.

Dimensions and tab layout
Technical views based on the dimensions in this product specification. Open either drawing to inspect the vector detail.
Evaluate 40Ah within the 90mm footprint
The 40Ah pouch battery cell provides 148Wh calculated nominal energy at a stated 376 ± 5g mass. It keeps the 90 x 190mm footprint of the smaller 33Ah family member. The gain in capacity comes with a different thickness and current specification, so the comparison must include the intended pack load.
Measure thickness at an agreed charge state
A JSN9590190 cell is specified at 9.0 ± 0.3mm thick at half charge and 9.6 ± 0.3mm at full charge. A receiving gauge set to only one nominal dimension could misclassify a sample. Define the state of charge and support method in the inspection procedure.
Review the 3C operating basis
This 3.70V high capacity battery cell lists 120A maximum continuous discharge and 40A maximum charge. Normal charging ends at 4.25V; the discharge endpoint depends on temperature. Those values concern the cell and must be reviewed again when interconnects, external leads and protection are added.
Prepare the joint and supply requirements
When buying a solid state cell for UAV packs, give the pack builder the tab geometry as well as capacity. This model has 30mm-wide tabs on 40mm centers with 20mm length. Agree the joint process, insulation and capacity-test basis before samples are compared or an order specification is frozen.

Related pouch-cell material is shown for production context. This 40Ah item is distinguished by its own thickness, capacity and current specifications, not by a shared workshop photograph.
Request a Configuration Review
For a 40Ah cell sample, provide the proposed cell restraint and the load profile. Confirm which capacity and thickness conditions will be used to approve repeat orders.

FAQ
Is the 40Ah cell simply a thicker 33Ah replacement?
The footprint is similar, but mass, thickness, capacity-test rate and maximum discharge figure differ. Recheck the load and assembly design before substitution.
Which capacity is guaranteed by the reference table?
The nominal value is 40Ah and the stated minimum is 39Ah at 0.2C and 25 ± 2°C. Acceptance should retain those test conditions.
Do the tabs come with an aircraft plug?
The drawing describes bare tabs. External connectors and protection belong to a separately specified battery assembly.
