3.7 General requirements. In the second sentence of step e, delete "tubes" and insert
"holes." In the third sentence of step e, delete "ports" and insert "holes."
3.8.6 Capacity and electrical performance. Delete the text and insert: "The rated
capacity of the battery shall be not less than 1.5 ampere-hours. To meet the capacity
requirement, each battery shall produce a potential of not less than 20.0 volts at not less than 60
minutes when connected to a 1.5-ampere load after being tested in accordance with 4.5.7 at
21° C (70° F) (1.5Ah/1.0hr/21° C/20.0 V at end of life). The battery 1C-rate shall be 1.5
amperes (see requirement 3 of the specification sheet). The battery shall also meet the
requirements of 3.8.18."
3.8.9 Cycling. Insert the following after the first sentence: "The battery potential shall
be not less than 20.0 volts after the discharge at the end of each cycle. The battery shall also
meet the requirements of 3.8.18."
3.8.16 Output performance. Delete the text and insert: "The battery shall produce a
potential of not less than 20.0 volts during and after the test of 4.5.28. The battery shall also
meet the requirements of 3.8.18."
3.8.17 Cold and hot temperature charge. Delete the text.
7.5 Add the following paragraphs:
"3.8.17.1 Half-hour charging. The battery shall produce not less than 1.25 ampere-hours
after being tested in accordance with 4.5.29.1.c and 4.5.29.1.h. The battery shall also meet the
requirements of 3.7 and 3.8.18."
"3.8.17.2 One-hour charging. The battery shall produce not less than 1.25 ampere-hours
after being tested in accordance with 4.5.29.2.e. The battery shall not sustain any damage when
a 28.25 ± 0.5 volt charging source is applied continuously to the battery during the test of
4.5.29.2. The battery shall also meet the requirements of 3.7 and 3.8.18."
"3.8.18 Diode resistance. The battery charging diode shall not be shorted or open after
the test of 4.5.32. The ratio of the charging diode's forward direction resistance to its reverse
direction resistance shall be not less than 1:100."
"3.8.19 Battery high rate discharge. The battery potential shall be not less than 18.0
volts during the test of 4.5.33. The battery shall also meet the requirements of 3.7 and 3.8.18."
