The battery at time of delivery shall read 12.6 V (OCV) or more at 25°C ±10°C,
provided it is measured within 14 days after delivery.
6.4 Internal resistance:
Give a full charge to the battery, and measure with AC Bridge (1 kHz test frequency)
the reading shall be less than 24 mΩ.
6.5 Capacity retention:
The remaining capacity of the battery, left standing for 3 months at 25° (±5°)C shall
be more than 80%. After 6 months it shall retain more than 60% capacity.
6.6 Characteristics against given load:
No deterioration shall be found with 42 A continuous discharge.
No deterioration shall be found with 105 A discharge for 5 seconds.
