3.14 Cycling service. Batteries shall contain plate thickness and formulation suitable for withstanding the
high cycling type of service encountered in vehicles such as law enforcement, school bus, and delivery
and shall be capable of meeting the cycle life test requirements of SAE J240. The class 7 battery shall be
capable of yielding minimum total cycles equal to 50 times its reserve capacity minute rating.
3.15 Cold activation of dry charged batteries. As 30ºF (-1.11ºC) dry charged batteries shall be capable
of producing a terminal voltage, under load, at the end of 15 seconds discharge equivalent to 1.2 volts per
cell minimum when tested as specified in BCI Battery Technical Manual for cold activation performance.
3.16 Reserve capacity. After cold activation and conditioning as specified in SAE J537, batteries shall be
capable of meeting the reserve capacity requirements as specified in the BCI Battery Technical Manual
Test sequence. A minimum of 90 percent of the batteries shall be capable of meeting or exceeding the
specified reserve capacity of SAE J537. The remaining batteries shall be capable of meeting or
exceeding 90 percent of the specified reserve capacity when tested as specified in SAE J537.
3.17 Cold cranking. At 0ºF (-17.77ºC), the battery shall be capable of meeting the performance
requirements of SAE J537.
3.18 Charge rate. The battery shall be capable of accepting a minimum charge rate of 2 percent of the
cold cranking rating of SAE J537.
3.19 Retention of charge. After cold activation and conditioning as specified in SAE J537and after being
on open circuit for 4 weeks at 75ºF (23.88ºC), without recharging at the end of this period, the battery
shall be capable of meeting the following requirements.
Classes 1, 2, 3, and 4: 75 percent of the reserve capacity rate of SAE J537.
Classes 5, 6, and 7:
90 percent of the reserve capacity rate of SAE J537.
3.20 Internal resistance for dry batteries. For dry charged batteries, the average terminal-to-terminal
resistance of each cell in the assembled battery shall be not less than 50,000 ohms.
3.21 Leakage. Each cell shall be capable of independently maintaining a pressure of 2 psi for a period of
5 seconds with a maximum loss of 0.1 psi.
3.22 Vibration. Batteries shall be capable of meeting the leakage requirement and the cold cranking
requirement for 0ºF (-17.77ºC), and shall not have any electrolyte leakage after being subjected to 2 units
of vibration as specified in SAE J537.
3.23 Identification marking. The following data shall be molded on the sides, the top of the cover, or
applied to a permanent electrolyte resistant label or plate securely and permanently attached to the
battery container.
Battery Identification Number:
Cold Cranking at 0ºF (-17.77ºC) rating (the test name or abbreviation thereof followed by the rating).
Manufacturer s Name or Identification (Manufacturer s name or identification may include private
branding).
Date of manufacture (month, year) and plant of manufacture, if the same battery is manufactured at more
than one plant, shall be legibly stamped or branded on the outside cell connector, top or side of the cover
or container. A plate or label permanently affixed to the top or side of the outer cover or container, or a
tag permanently affixed to the terminal post is acceptable. Coded information is acceptable provided the
key to the code is made available.
3.24 Condition for shipment. Batteries shall be in one of the following conditions at the time of shipment.
3.24.1 Batteries intended for immediate use or wet storage with charging equipment. Filled with
electrolyte and fully charged.
