34、inspections. A 2 %sample, to a minimum of five cells per lot shall undergo one complete charge-discharge cycle to verify the integrity of the lot. Acharge-discharge cycle is defined as a full charge followed by a full discharge to the depth typical for the subject chemistry.Additionally, the physica

Sampling shall be in accordance withANSI/ASQ Z1.4-2008.Any alternate plan must be approved by the GAA.The sampling plan shall accept on zero defects.5.2.3 shall be performed
36、 on a 2 % sample to a minimum of five cells per lot. Thecapacity tests and physical inspections may, but are not required to be performed on the same cells.5.2.1.1 Capacity TestThe sample shall undergo one complete charge-discharge cycle to verify the integrity of the lot. Acharge-discharge cycle is

A subject cell is to be rejected for any ofthe following conditions:(1) Swel

If a solder connection is unacceptable,it may be reworked by the pack assembler.5.2.2 Received-Voltage TestThe pack assembler shall measure this voltage on every cell i

The measurement is taken directly at the cell tab, bypassing anyprotection circuitry that may be connected. In the event that a cells received voltage is outside limits that are normal or recoverablefor t
41、he particular chemistry, the cell shall be rejected. The received voltage shall not vary significantly from what is consideredthe typical chemistry-specific storagestorage/shipping voltage or the mean measurement for the bulk of the lot. The receivedvoltage for a lot will typically vary little from

If the cell is within this range, the inspections giveninoutside the storage/shipping voltage, the 5.2.3 are not required, although procedures

If, however the cell is within those limits but the received v
