Part A
Parameters for non-rechargeable batteries
1. Minimum average duration: minimum average time reached by a sample of batteries on discharge when used under specific conditions, such as temperature and relative humidity.
2. Delayed discharge performance: the relative decrease of the minimum average duration, with the initially measured minimum average duration as the reference point, after a defined period and under specific conditions, such as temperature and relative humidity.
3. Resistance to leakage: resistance to unplanned escape of electrolyte, gas or other material.
Part B
Parameters for rechargeable batteries
1. Rated capacity: the capacity value of a battery, under specific conditions, such as temperature and relative humidity, and declared by the manufacturer.
2. Charge (capacity) (
7
) retention: the capacity that a battery can deliver after storage, under specific conditions, such as temperature and relative humidity, for a specific time, without a subsequent recharge and expressed as a percentage of the rated capacity.
3. Charge (capacity) recovery: the capacity that a battery can deliver with a subsequent recharge after storage, under specific conditions, such as temperature and relative humidity, for a specific time and expressed as percentage of the rated capacity.
4. Endurance in cycles the number of charge and discharge cycles a battery can perform under specific conditions, such as temperature and relative humidity, before the capacity drops below a specified fraction of the rated capacity.
5. Resistance to leakage: resistance to unplanned escape of electrolyte, gas or other material.
