The Specification SCL-6870A represents versatile performance for silver-zinc secondary batteries. The design is deemed satisfactory for the varied requirements of this specification. Lot acceptance testing has been successfully completed for the vented series of secondary silver-zinc batteries as described by SCL-6870A. Forty 40 dry uncharged batteries of each capacity have been forwarded to the USAECOM as a result of this testing. This acceptance testing included capacity, -20F, high rate, environmental and charge retention tests for the BB-462 U, BB-463 U, BB-464 U and BB-465 U. It has been determined that the 160F, 7 day charge retention test is essentially a destructive test. After exposure to 160F for seven 7 days, the batteries met specification requirements but it was noted that the cells would short-out within ten 10 cycles. Author
