Naval Surface Warfare Center, Indian Head has determined that the battery connection in the subject inflators are susceptible to failure when used at temperatures below 20 degrees Fahrenheit. The subject inflators that have this problem were made between 2006 and 2008 with Lot numbers CAX06E001-001 through CAX08L003-015.
The investigation revealed that at temperatures below 20 degrees, the battery case can fail, causing the connection between the button cells within the battery to lose contact with each other resulting in intermittent loss of voltage. The current battery caps (black in color) only applies 1 pound of force which is insufficient to assure circuit integrity. The manufacturer, Conax Corporation, redesigned a stronger, more reliable cap (beige/gray in color). The new cap applies 8 lbs tension, holding the button cells tightly together and eliminating the failures.
Per NAVAMMOLOGCEN Naval Message 141940Z FEB 11, each ship/airwing should determine requirements for replacement caps and submit a consolidated request by e-mail to SANDRA.YANDELL@NAVY.MIL. New battery caps are a no cost item to the ship/airwing. Please provide quantity, completed mailing address, and point of contact for delivery. The black cap shall be replaced within 180 days from the date of the above naval message. When the new battery caps are received, unscrew the black cap and screw on the new battery cap. Old black battery caps are not HAZMAT and can be disposed of after being replaced.
